Dipole field characterization by floating wire and field map ray tracing

The floating wire (FW) technique was applied to determine particle trajectories in three dipoles which form the magnetic spectrometer ANKE installed in the accelerator ring COSY Juelich. Methodical improvements of the well-known FW technique result in extended applicability and high accuracy. The FW measurements compare well with field map based trajectory calculation using the GEANT code.

516 損耗センサ付切削工具におけるインプロセス制御システム

An in-process tool wear meter for turning has been developed by combining a sensor-integrated insert and simple signal processing technique. The sensor consists of TiN thin wire traces, which are deposited on the flank of every cutting corner of ceramic insert in parallel with the edge. As flank wear breaks the wire traces at a rapid pace, a step increase in sensor resistance occurs. This feature of the resistance signal allows for the easy interpretation of the sensor resistance output in terms of the wear amount. The sensor mechanism ensures highly reliable in-process measurement of flank wear in conjunction with appropriate signal processing. In a series of test experiments, with varied cutting conditions, the practical reliability and usefulness of the meter was confirmed. In addition to wear measurement, it was shown that the sensor could signal the machine to automatically stop when the insert wears out.

Holograms as Job Performance Aids

The nature of the new technology of holography will be briefly described and holograms will be demonstrated. The unique characteristics of holograms will be sketched and their particular value as aids to job performance will be discussed. In the last few years, the state-of-the-art in holography has advanced at an accelerating rate. It is a technology which allows objects to be presented in three dimensions as though they really exist in space. In fact, there is no visual test to discriminate between the real object and the holographically re-created object. As visual aids in wire tracing and assembly tasks, they are equal to or better than photographs or line drawings. They have been used on the windshields of moving automobiles to create the perception of on-road objects in driver testing. In the last two years they have been commercially available to colleges for teaching hundreds of difficult concepts, such as the DNA helix.
