Title: Positioning device
Inventor: KAWAMATA NAOKI
IPC: G01B11/00
Filed: 1994-05-11
Abstract: PURPOSE:To position a load arm and a swing arm in a non-contacting manner and to eliminate continuous vibration by providing a distance sensor that detects a distance between the load arm and swing arm. CONSTITUTION:A shift between a target signal 1 and an output signal of a differentiator 6 is generated by a subtracter 12 to be applied to a motor via an amplifier 2 and a compensator 3 as a control input. On the other hand, the signal of a differentiator 6 that differentiates an output of an encoder 5 is subtracted from an output of the amplifier 2 by a subtracter 13 and the output signal is inputted to the compensator 3. A distance sensor 14 detects a differential distance between a load arm 4 and a swing arm 10. A difference between the distance and a target distance 7 that is given from an external section is detected by a subtracter 15. Thus, when the load arm 4 moves, the distance sensor 14 detects the detected distance between the load arm 4 and swing arm 10, then a positioning loop system 18 of the swing arm 10 operates so as to eliminate the difference between the detected distance and target distance so that a constant distance is maintained to be stopped.

Title: Measuring apparatus of flow speed in turbid fluid
Inventor: FUJIMURA AKIHIRO
IPC: G01P5/00
Filed: 1980-09-01
Abstract: PURPOSE:To measure the flow speed of turbid fluid in a specific part, by detecting the Doppler's shift of laser beam caused by a composite speed of vibration due to sound wave pulse to be sent and the flow speed at a measuring apparatus of the flow speed of the turbid fluid. CONSTITUTION:Turbid water is entered into a water bath 1 from an inflow port 2. Light from a laser 9 passes through a glass plate 10 to be reflected by turbid particles in the bath and then reaches a photomultiplier tube 14 through a lens 12 and a glass plate 11. When the particles are moving at a constant speed, a constant-frequency beat is generated between the turbid water and the original light reflected by the plate 10 and 11 by the Doppler's shift. At this time, when vibration is given to the particles by an ultrasonic pulse by means of a pulse generator 4, an alternating current generator 5 and a vibrator 6, said vibration is overlapped with the flow speed each other and the frequency of reflected light is varied and after all, the beat frequency is not constant and a amount equivalent to of alternating cirrent caused by the vibration is included. The flow speed is known by observing by an oscilloscope 20 through a tuner 16, a detector 18 and an amplifier 19.

Filed: 1995-05-22
Abstract: PURPOSE: To reduce the influence of a shape error and make it possible to condense X rays with high precision by pressing a mirror from the back of it against ridges of a support with a wedged section through vacuum chuck. CONSTITUTION: A support with a wedged section is, for example, a square aluminum alloy plate 10 where numerous parallel wedges are formed at 1mm intervals on one face. The support is placed so that the ridges of the wedges around the alloy plate 10 can fit the internal circumference of a box 6. Spacers with sufficient size and strength are placed appropriate distribution between the other face of the alloy plate 10 and the base of the box 6. In a reflective mirror 5, multi-layer films are formed on a silicon wafer cut off square. Then, the mirror 5 with little distortion along the ridges of the wedges is obtained by putting the mirror 5 on the box 6 in such a way as to use the former as an upper lid for the latter and expelling the air in the box 6 from a vent 11 (vacuum check).  The appropriate setting of the intervals between the wedges ensures the high precision also in the direction orthogonal to the ridges.
