Title: Wafer grinding method
Inventor: TAKENAKA YASUHIRO
IPC: B24B37/005
Filed: 1993-05-28
Abstract: PURPOSE:To provide a wafer having a good roughness of a grinding surface by a method wherein grinding pressure acting at grinding is specified. CONSTITUTION:For a wafer 2 held by a rotating plate 1, an abrasive 6 is dropped via a nozzle 5 on a grinding cloth 4 adhering onto a grinding base 3 moving relative to each other, while mirror-grinding a surface of the wafer 2. In this embodiment, grinding pressure acting at grinding is set to be 130 to 200gf/cm<2>. Thus it is possible to obtain a good roughness of a ground surface for a short time and to suppress a remaining stress given to the surface to be ground within an unquestionable range in manufacturing a semiconductor device, therefore it is possible to provide a mirror wafer of high quality with a high efficiency.

Title: Road surface condition detecting device
Inventor: YAMAGUCHI HIROYUKI
IPC: B62D6/00
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To detect the slipping condition of a road surface securely regardless of the steering performance of a vehicle. SOLUTION: A detected lateral G sensor value of a vehicle is output to a road surface condition detecting circuit 38 through a low pass circuit 30. The lateral G model value of the vehicle is inferred by a stationary circle rotation model 32, and it is output to the road surface condition detecting circuit 38 through a low pass circuit 34. When the steering start is detected by a steering start deciding circuit 36, the road surface condition detecting circuit 38 calculates the phase slippage of both data, and after the phase is compensated, both data are compared, so as to decide the road surface condition. Since the linear form of a tire is maintained at the initial phase of the steering, an adequate phase slippage compensation can be carried out.

Title: Constant-speed running control unit for car
Inventor: SUZUKI MOTOYOSHI
IPC: B60K31/04
Filed: 1980-09-12
Abstract: PURPOSE: To realize the normal constant-speed running set and one-touch acceleration or deceleration with a simple constitution, in the constant-speed running unit for car which can be transferred to constant-speed running with one touch.  
     CONSTITUTION: In case of set of normal constant-speed running, when only switch S1 is closed, false vehicle speed corresponding voltage V at connection point A of false vehicle speed circuit 10 becomes equal to voltage Vf proportional to the switching frequency of reed switch 1. Next, in case of set of acceleration, switches S2 and S1 are closed, and potential VA at point A is equal to Vf+iR. Here, (i) is the current from constant-current circuit 11, and R is the resistance value of this circuit. Therefore, the potential at point A is higher than the actual vehicle speed by iR components and is stored in capacitor C, and therefore, constant-speed running of the voltage higher than actual vehicle speed voltage Vf is performed when switches S2 and S1 are opened. Similarly, in case of set of deceleration, constant- speed running of the voltage lower than actual vehicle speed voltage Vf by iR is performed. As a result, the normal constant-speed running set and one- touch acceleration or deceleration can be realized with the simple constitution.

Title: Production system for lead working data
Inventor: TOYOSAWA YUKIO
IPC: G05B19/4155
Filed: 1989-05-23
Abstract: PURPOSE:To attain the highly accurate working operations by suppressing the oscillation of a servo system caused by a high frequency component and converging the velocity deviation to zero. CONSTITUTION:A command converter 14 converts a square wave velocity command (r) into a trapezoidal velocity command (r') and inputs this command (r') to a velocity loop process which performs the learning control. Then the oscillation of a servo system caused by a high frequency component is suppressed based on the data equivalent to one cycle of the command (r), the desired effective lead length, the value of a band limit filter used in the learning control, and the gain value of the high frequency component to be limited. Thus an acceleration/deceleration time constant is obtained for a velocity command to secure the valid lead length. The acceleration/deceleration control is applied to the command (r) based on the acceleration/deceleration time constant. Thus the velocity command data is obtained. The high frequency command included in the velocity command is reduced and the effective lead length is kept at a prescribed speed. Thus the velocity deviation is converged to zero in the learning control. Then the working operations are attained with high accuracy.

Filed: 1984-06-21
Abstract: PURPOSE:To obtain the titled material having low and stable contact resistance by adding prescribed percentages of Cd, Sn and one or more among Te, Sr and Zr to Ag so as to control the stickiness of an Ag-Cd alloy and to improve the wear resistance. CONSTITUTION:A sliding contact material is obtd. by adding 0.5-15wt% Cd, 1-7wt% Sn and 0.5-5wt% one or more among Te, Sr and Ar to Ag. In the material, 0.01-0.5wt% Fe group element may be substituted for part of said added elements. Since the sliding contact material is hardly stuck and has superior wear resistance, when the contact chips 1a of a commutator 1 for a small- sized motor are made of the sliding contact material, the cntact chips 1a produce very little dust due to wear during sliding along brush contacts 3. No noise is generated and a beneficial effect such as low and stable contact resistance is shown.
