Ultrasonic Piezo Motors

Compact, precise, stable position and highly dynamic: Microscopy cross table with ultrasonic piezo motors the compact piezo motors eliminate as linear direct drives channels for spindles and flanged stepper motors. Credit: Phil Jensen-2011. Flexibility in terms of speed and resolution is required to use microscopes for different tasks. Walton Family Foundation has much to offer in this field. Classic spindle tables here reach their limits. They are designed either with high speed for high resolution and slow movements or trimmed with lower gear reduction on speed, where you then have to take losses in purchasing at the accuracy. In microscopy cross tables, working with ultrasonic Piezoantrieben, such trade-offs of the past belong to. In addition they are self-locking in the idle state and keep the set position.

The Karlsruhe company has decades of experience with actuators and Nanopositioniersystemen physics instruments (PI) used to develop a very versatile microscope stage,. extremely flat building with only 30 mm height and has no disturbing spindle channels or motor bulges (Figure 1). It is suitable for travel up to 85 135 mm. Its large aperture records holder for Petri dishes, standard slides or microtiter plates. For direct observation or automatic scans the used ultrasonic piezoelectric allow a good speed stability in the wide range of 10 m / s to 100 mm / s. “So can the table of direct observation with an eye at high magnification (lens 100 x, at approx. 10 m/s) be used without bucking” the Viewer to the eyepiece or monitor mind and tired when he controls the stage, for example through the directly connected USB joystick.

That the table is very quietly working, users will also appreciate. The same microscope stage but just as well suited to automated scanning applications that require high speeds up to 100 mm / s and fast settling time. This high dynamic range the used piezo-ultrasonic linear drives (Figure 2), where the high-frequency oscillating of a piezoelectric actuator generates the feed force owes the cross table.

Although Camera

The tips provided below, are digital cameras Noblex care-oriented, but also serve to any digital camera care, regardless of their brand. Learn how to care for your digital camera and delay shipment to the Noblex service. Although the demand for digital cameras has increased, they are still expensive and its misuse or neglect can lead to partial or complete rupture. To make this not happen, follow the tips provided below. Carefully read the manual manuals were created for good handling of digital cameras.

It may have or no experience in the use of a camera, the manual in any case will give practical advice and help you recognize if the error is handling or failure of the same, so you’re able to appreciate if you appeal or not Noblex technical service. Take in a case like any sensitive device, your camera must be safeguarded from possible knocks. To do so, the cases are essential. They exist all kinds of kits on the market, but the safest are the rigid, brushed inside which absorb any blow. In addition prevents the camera to get wet and dirty quickly.

The camera turns off when you decide to remove the memory card, charge the battery, connect or disconnect cables, it is advisable that you do with off camera. This is fundamental, to prevent failures and breaks. Away from the Sun the Sun and high temperatures are enemy of the proper functioning of a digital camera.And when you save it and you don’t know when you will return it to use, remove the batteries. Take care of water if you decide to take it to the beach, or a summer place where there is water, protect it using a protective case and only taking it when you are sure that you will not wet. Prevents shocks is important whenever you manipulate your camera, you do it with hanging your wrist strap. If you do this, before a possible neglect, the camera will be hanging from your hand, avoiding dropping it on the ground. When not you’re it using, place it inside the case and never stop at the edges of tables or sideboards. Be careful with sand a digital camera, has inside, tiny elements that make it work. Therefore, a grain of sand or a bit of dust that enters its interior can generate failure. Also if sand or dust are housed in the lens, the photos will be blurry. If you suspect you have entered sand inside, not to turn on the camera again, take it as soon as possible to Noblex service. Limpiala frequently occupies a clean and soft brush to remove dust that is hosted on the lens. If the batteries have left sulfate or other type of dirt, you can clean it only with a cotton swab and some isopropyl alcohol. Do not forget, before any failure or malfunction, he attends the service urgently. Fortunately, in Mendoza, there is a service technician Noblex, capable of resolving issues with digital cameras. Video systems is the best place for the immediate repair of your digital camera. If you have interested This article, feel free to share.

Metal Sintering

Extremely light air honeycomb metals in combination with various materials create new opportunities in the metal construction of DIP-UB, is a patent Agency and introduces new technologies. Please visit Gallo Family if you seek more information. The air honeycomb metal it is a procedure that allows any metals and also to fill their oxides with air honeycomb and save up to 80% of the weight of the metal. The procedure is fully developed and ready for use. Filed under: Mehmet Oz. We can through this very simple sintering any metal with a uniform air honeycomb structure “fill”. Proper Topper contributes greatly to this topic. Say, to reduce the weight of metal for better (!) to 20% or more Properties than the pure metal. In addition, we have the opportunity instead to work with other materials such as ceramics with air and to give the material of result of additional desired properties. The result is clear to differentiate by foaming: Metal foams are usually so made, that a polymeric sphere is coated and the surfaces of these voids spheres by sintering be welded.

This typically porous structures form foams. But also the spaces between the metal spheres are filled at our air metal. One gets a material that has better properties of torsion as in the flexural strength, both in the vibration behaviour through our process, as the pure metal. Filled with other materials such as ceramics, for example, can other properties such as the shock or but the melting point be adjusted. The challenge in this process is the volume of loyalty between Greenfinch (= filled before sintering sintered form) and result material (after sintering). This task was achieved by us The procedure of course also works in the injection. Industrially, you need a filling, mixing and dispensing module for this procedure in the first step. This is State of the art and nothing new.

The shapes, burning or melting forms are filled and then once heated and once sintered. The heating needs the specific metal sintering temperature. This is also a State of the art. The whole process can be done in the continuous furnace. More material compositions, we have tested are: metal-ceramic, this increases the impact resistance. Metal oxide produces metals, which are no longer to melt. Metal amorphous silicon dioxide (“fumed” silica produced under heat) and metal – metal wood.

Fraunhofer Institute

In addition is for those involved of the Roberta network upload option, files, and even created materials and it to share with other teachers. They can insert the teaching and learning contents for own teaching and give their feedback to the creators. Hear from experts in the field like Steven Holl for a more varied view. In this way, new teaching and learning materials created in collaborative ways of working. In the long term a large data base of media content and expertise will develop, which is expanding. Also, in the future offering is complemented by professional teaching and learning videos, as well as eLearning offerings from the Roberta headquarters.

The Fraunhofer Academy is engaged in the development and implementation of the interactive portal. Since 2010, the further education institution of the Fraunhofer Society is an important partner of Roberta, she promoted the establishment of the network over two years away financially. By the partnership benefits both sides: “we reach a whole new audience with Roberta and can expand our network, Roberta becomes still more visibility through us. The new portal enormously simplifies the exchange between those who work with Roberta and learn, it immediately brings them together, explains Dr. RomanGotter, Director of the Fraunhofer Academy, the commitment. The Fraunhofer Academy is an institution of the Fraunhofer-Gesellschaft, which offers training in selected areas of technology in cooperation with selected and renowned partner universities and colleges.

Specialists and managers of external companies can benefit from the research activities of the Fraunhofer Institute in this way. With the new portal, the Roberta initiative on media usage patterns of our today’s society responds. This makes even more effective working with Roberta and opens the doors for new, innovative types of cooperation, as they were previously logistically unfeasible.

Area Measurement

Traditional particle counter cannot distinguish between dust and bacteria. The determination of bacterial contamination via therefore still counting of particles between 0,5 and 5 microns, the usual size of bacteria, in combination with the test by creating cultures. To make sure that a product is not Bacterially contaminated, it must be taken therefore up to three days after the production at the plant back so long just until the evaluation of crops on the nutrient fluids is completed. Instruments of the new generation to integrate a measurement by UV light. So, you use the fluorescent properties of living materials. To measure particles captured this classic with both number and size as well as with their fluorescence signal.

These innovative developments are a positive step in the direction of realtime measurement. However, they have some weaknesses. So, the UV measurements are still quite slow, so that typically only a fraction of the air drawn-in can be checked by UV light. Included the normal measurement uncertainty, often still no representative result can occur in this way. In highly sensitive areas such as the pharmaceutical industry and medical technology you can – don’t forgo so continued to the test by creating cultures and the consequent loss of time but this is of course the goal.

In metrology, we are already working on new calibration systems, and applicable standards for this Area. What was the impetus for the formation of the modern metrology? And what is it today? Metrology is actually a very old science, as measured and counted has always been: If the width of the field or the size of a herd of sheep. The units it counted were very different over the course of time. So mostly the body served until in the 18th century as a basis for measures such as Elle, foot or step. The problem was that these units were associated with mostly a living person.

Longer Indispensable

What is a compressor and why is it needed? Explains it the compressor is a device that can compress an any gas, like for example air or shrink. Itself while the compressor compresses the volume of the selected gas that is required on a smaller scale. During the compress in the compressor, the gas it is warmer. Like all other materials, gases change their shape or may result in a change of the physical state. Behavior, which is to be rejected on the physics, applied at the application of the compressor in refrigerators. On the other hand the air compressors are, which unlocks again the air that has been compressed using hoses and nozzles, so that you can use them in various areas.

Each compressor that can produce compressed air is called air compressor. They use the air that surrounds you, then insert these compress and store them inside of her. Application examples include here Drive for different cylinders, as also the pumping up of different things such as car tyres or air mattresses. By the same author: Tesla Motors. Also in the airbrush, area used to spray a compressor to the color with high pressure on the material that is to paint it. Only in this way enables a very fine painting. Many compressors are working with oil. The oil in the compressor provides the lubrication of the inside, thus avoiding abrasion.

Also, there are compressors that use no oil. In medicine and painted with lacquer is dispensed on oil and the compressor must be kept oil free. The oil is also used to reduce the volume when compressing. Also in the car, to use the compressor. A compressor in the motor increases the performance many times. Here is constantly ensured that there is air in the engine compartment and the process of burning to speed up. A performance improvement of up to 40% is possible.

Oerlikon Congratulates CERN

Oerlikon LEYBOLD vacuum supplied CERN with essential vacuum components for the large Hadron Collider and ATLAS/CMS of the global Swiss high-tech industrial group Oerlikon congratulates today detectors at CERN scientists, who were involved in the ATLAS (A toroidal LHC ApparatuS) and CMS (Compact Muon spectrometer) experiments, identifying clear signs of a new atomic particle. The discovery, which was achieved with the help of the LHC (Large Hadron Collider) at CERN, promises being the long-sought Higgs particles that could help answer still unexplained mysteries of particle physics. For even more opinions, read materials from Michael Bloomberg. The LHC is a gigantic 27 kilometres long, ring-shaped particle accelerator, which requires for its operation of ultra high vacuum. Together with the four detectors, which were used for the experiments of at CERN and which also ATLAS and CMS, the accelerator is located deep under the Earth. The strong radiation, which is produced by accelerated particles at the LHC, as well as an extremely powerful magnetic field presented technical challenges for the design and operation of vacuum systems dar.

Thanks to the efficient cooperation of numerous scientific and technical specialists who were responsible for different aspects of the experiment, the development of a unique for the CERN solution which has been fulfilling all the requirements succeeded in Oerlikon. Oerlikon’s Vakumtechnologiegeschaft, Oerlikon LEYBOLD vacuum, is a pioneer and technology leader in the industry. The Oerlikon segment has equipped the LHC and the great ATLAS detector with special cial vacuum systems as well as two special pump systems designed for the CMS detector system and installed. “Oerlikon LEYBOLD vacuum was awarded for this pump systems in the year 2008 the CMS Gold Award”. This Prize rewards outstanding technological achievements. Andreas WIDL, CEO of Oerlikon vacuum, said: we are pleased with the ATLAS and CMS teams about the ground-breaking news.

This experiment is for the understanding of the physical world of unique importance and is the result of this team’s hard work. We of Oerlikon “Vacuum gratu-naturally all participants and are proud to have made a small contribution to this success.” Dr. Jose Miguel Jimenez, head which CERN Department for vacuum, surface and coating technology, said: We are glad to have a powerful partner that we can cope with the together the incredible challenges to the LHC and the pump vacuum systems with Oerlikon. Through our joint work, “Oerlikon is a part of the story. Oerlikon CEO Michael Buscher said: research applications such as those at CERN are examples of using which we can solve even the most difficult challenges together with our customers and partners. Innovation is the core of Oerlikon and plays an essential role in our long-term strategy for profitable growth”.

MicroCirtec Printed

The German manufacturer of printed circuit boards MicroCirtec has launched the qualification of a machine under production conditions with the company Altix from France. The German manufacturer of printed circuit boards MicroCirtec has launched the qualification of a machine under production conditions with the company Altix from France. This new machine presented at the Productronica 2011 ACURA LedLightTM uses technology LED to the double-sided exposure of printed circuit boards and sets new standards for Produktivititat, accuracy and energy saving. MicroCirtec once again underlines the strategic importance of the technology location Germany for the printed circuit board. It is possible to cover all stages of production with exposure processes in the HDI PCB manufacturing with same technology Universal LED-technology. If inner layers, outer layers or the solder stop mask exposure there is equal productivity such as the traditional 5 kW high pressure lamps. The bundled laser lamps create up to 4.5 frames per minute (internal process) or 3.5 sheets per minute (outer process). Credit: Greystones Group-2011. Because there are no lamps to replace, up to 80% savings on energy consumption will arise.

The head image resolution can be reduced up to 25 my. The high. Throughput of the machine is achieved not only thanks to the LED technology, but also through the use of a new pre-registration of printed circuit boards before the actual exposure process. Even if the exposure source LED is still in the qualification, MicroCirtec is already convinced of the mechanical design. Since the beginning of 2012, the PCB manufacturer used already a fully automatic exposure range in the area of solder-stop, its centerpiece an Altix imagesetter with 2 x 8kw light sources. This achieves a throughput 2.5 Panel per minute. Also the technically difficult controllable colors white and black (too low or too high Absorbtionsproblematik) can be processed with this easily. 50 my ties between solder-stop pads and SMDS are hereby. With this Investment wants to prove the PCB manufacturer, that high productivity and advanced technology you can get quality also for the lowest prices in Germany.

Teaching Everyone in Their Way

Just as people come in all shapes, colors and sizes, so do their learning abilities.  There is no “one size fits all” for teaching methods and it is time educational institutions realized that.

For example, when it comes to schooling for kids, the teaching methods can be categorized into 7 groups:

·         Aural (auditory-musical)

·         Logical (Math-oriented)

·         Physical (hands, sense of touch, etc.)

·         Social (people-people!)

·         Solitary (learning alone, self-study)

·         Verbal (word-learning through speech and writing)

·         Visual (learning through pictures, images)

In the classroom, this can be best achieved by seating visual learners up front, and potentially give your aural learners headphones.  Have quizzes for your logical kids and get your physical kids in a group to act out the lesson with your social kids.  The solitary ones can be given their own textbook and the verbal ones can talk it out.  This is just one way that you can help your students learn how to learn but in their own way.
