Title: Device for measuring mirror face accuracy of spherical scan-type non-contact mirror
Inventor: ONO MAKOTO
IPC: G01B11/30
Filed: 1985-04-04
Abstract: PURPOSE:To detect the mirror face accuracy in a non-contact state by scanning the interior of a sphere while a counter is counting the time until when a pulse transmitted from a pulse laser oscillator generating a pulse signal is reflected by a subject to be tested and returns. CONSTITUTION:A horizontally rotating mechanism 8 is fitted on a base 2, and thereon a vertically rotating mechanism 7 is fitted. A pulse laser is transmitted from a transmitting part 9 fitted on the upper part of the vertically rotating mechanism 7, and a receiving part 9 receives the pulse laser which is reflected by the subject to be tested, an antenna 1, for instance, and returns. Then a built-in pulse counter counts the time from transmission to reception. A control ler not-shown in figure, rotates the sphere in all directions by the prescribed angle to scan the sphere, and length is obtained from the required time at each point. The obtained pole coordinate display is converted into three- dimensional coordinates, X, Y and Z. Thus the mirror face accuracy is detected in the non-contact state and the breakage of the surface due to malfunction can be prevented.

Inventor: RYU TADAMITSU
IPC: G09G5/00
Filed: 1990-03-20
Abstract: PURPOSE:To surely perform initialization and the change by storing a data update period, a variable information ID, and a variable information classification, which are required for start of a display control part and a variable information gathering part, in a variable information management file and providing the variable information gathering part with the adjusting function. CONSTITUTION:A display control part 26 performs the update processing of variable information displayed on a display part 21 by new variable information to control the display.

The value of an update period in a variable information management file 28 is rewritten with the value of this update period. Thus, variable information displayed on the display part 21 is synchronously updated correspondingly to new variable information periodically outputted from new desired variable information output parts 22, 42 and 52, and the changes of setting related to this display control is surely performed.

Title: Wafer polishing method
Inventor: KAWASE SHIGENORI
IPC: B24B37/30
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To polish a semiconductor wafer uniformly over its entire surface using a polishing cloth to make the surface smooth and avoid causing localized polishing, by pressing the wafer through combined backing pads mutually different in hardness. SOLUTION: In the polishing for a wafer with use of a polishing cloth, an inner and outer pads 2 and 3 mutually different in hardness form a backing pd 1. As a result, the pressing force exerted on the wafer is partly controllable to make it possible to uniformly polish it over the entire surface. The cushion effect at the wafer's marginal area is apt to appear at the polishing cloth, using an outer pad 3 having a higher hardness than of the inner pad 2, and hence the localized polishing at the wafer's marginal area is suppressed. And at the central area of the wafer, this effect is apt to appear at the backing pad and hence the dishing at the central area of the wafer is suppressed.

Title: Correcting method for field pole detecting position of synchronous motor
Inventor: KAI TOORU
IPC: H02P23/18
Filed: 1984-04-12
Abstract: PURPOSE:To prevent a vector control system from possibly running away due to a positive feedback by judging a feedback polarity, and inverting the detected phase when the feedback polarity is positive. CONSTITUTION:When a phase difference delta0 falls within a range of pi/2<delta0<=3pi/ 2 in the correction when a torque disturbance DELTAT is applied by a torque disturbance generator 20, a vector control system becomes a positive feedback to run away. In this case, the polarity of the signal DELTAT and the polarity of a torque command T are monitored, and if both have the same polarity, it is judges as that the vector control system runs away. After the runaway is thus detected, the phase is shifted by pi from the phase difference delta0, i.e., inverted to be corrected.

IPC: F02M7/28
Filed: 1983-04-23
Abstract: PURPOSE:To prevent mixture from becoming too lean and stabilize the operation of the engine by a method wherein the mixture is made rich when a pressure difference between the fore and aft parts of a carburettor, equipped with the supercharger at the upstream thereof, has become large. CONSTITUTION:A switch 12, operating by the pressure difference between the upstream part 16 of the carburettor and the downstream part 18 of the same, is provided in the engine equipped with the supercharger at the upstream of the carburettor having a throttle valve 17. When the supercharger is driven and the throttle valve 17 is at the vicinity of the closed position thereof, said pressure difference becomes big, therefore, the switch 12 is closed to operate the solenoid valve 7, which closes an auxiliary air bleed 6 through a control circuit 8. According to this method, the mixture of the carburettor becomes rich and the air- fuel ratio, whih has a tendency to become too lean, may be kept in proper state.

Title: Inductance type displacement sensor
Inventor: SHIRAO YUJI
IPC: G01B7/00
Filed: 1988-03-28
Abstract: PURPOSE:To exactly detect the displacement of an object to be measured by surrounding other part than the surface opposed to the object to be measured by a shielding wall having layers consisting of a magnetic material and a good conductor. CONSTITUTION:A displacement sensor 10 is constituted roughly of a coil 12, a core 14 and a shielding wall 16. Also, the shielding wall 16 is constituted of a layer (magnetic material layer) 18 consisting of a magnetic material, and a layer (good conductor layer) 20 consisting of a good conductor. This shielding wall 16 surround all the parts except a void part 24 in which the sensor 10 is opposed to an object to be measured 22. At the time of operation, among lines of magnetic flux generated from a control coil and a motor, etc., that of a low frequency is shielded by the magnetic material layer 18, and on the other hand, the line of magnetic flux of a high frequency is shielded due to a fact that an eddy current is generated in the direction for obstructing its line of magnetic flux by the good conductor layer 20. As a result, the inductance to be detected in the sensor 10 is varied, based on a variation of a dimension (l) of the void part 24 between the object to be measured 22 and the sensor 10, that is, a displacement of the object to be measured 22, and the influence of a magnetic noise from the outside is eliminated.
