Title: Non-contact discrimination of semiconductor material conductivity type and equipment therefor
Inventor: YUKI TADANOBU
IPC: H01L21/66
Filed: 1989-06-22
Abstract: PURPOSE:To discriminate the conductivity type of semiconductor material with high precision in a non-contact way, without the influence of existence of an oxide film, by charging a smoothing capacitor with photoelectromotive force, and measuring the voltage of the capacitor. CONSTITUTION:Semiconductor material 4 is intermittently irradiated with light. In the case of P-type semiconductor, positive photoelectromotive force is generated in the semiconductor material 4. In the case of N-type semiconductor, negative photoelectromotive force is generated in said material. After said photoelectromotive force is detected by detecting electrodes 5, 6, electrostatically coupled with the semiconductor material 4, a smoothing capacitor 9 is charged by the detected voltage. P-N judgement of the semiconductor material 4 is done by measuring the voltage of the charged smoothing capacitor 9. Thus the conductivity type can be discriminated by using the photoelectromotive force utilizing light, while the detecting electrodes are not in contact with the semiconductor material, differently from the conventional case. Hence misjudgement is not caused by the hindrance of an oxide film, differently from the conventional case, and very highly precise judgement can be achieved.

Filed: 1988-06-30
Abstract: PURPOSE:To obtain a displacement output having a good linearity from the title measuring instrument by controlling a light emitting output so that the photocurrent outputted from a light receiving element can become a specific one. CONSTITUTION:A light receiving element 20 outputs two currents of I1 and I2. The currents I1 and I2 are respectively converted into voltages V1 and V2 through current/voltage conversion circuits 21 and 22 and the voltages V1 and V2 are respectively amplified through amplifiers 23 and 24. The amplifier 23 outputs a voltage V1 signal as it is and the other amplifier 24 outputs another output signal which is obtained by multiplying the voltage V2 signal by K (Knot equal to 1). Then the voltage V'1 and KV'2 signals respectively outputted from the amplifiers 23 and 24 are inputted to an adder 25 and converted to (V'1+KV'2). Moreover, the light emitting power of a light emitting element 17 is controlled by means of a light emitting power control circuit 26 so that the output voltage (V'1+KV'2) of the adder 25 can be kept always constant. Then the voltage V'1 signal is inputted to a gain adjustment circuit 27 and an analog signal is outputted from the circuit 27 in corresponding to an appropriate output gain. Thus a displacement output is obtained.

IPC: G03C5/00
Filed: 1992-06-19
Abstract: PURPOSE:To recycle the waste liquid generated accompanying the photographic processing of photographic sensitive materials by an automatic developing machine, etc., for photography by incorporating substantially no formaldehyde into a stabilizer. CONSTITUTION:The stabilizer contains substantially no formaldehyde at the time of using the distilled water generated by subjecting the waste stabilizer to an evaporation concentrating treatment at <=90 deg.C under a reduced pressure of <=700mHg as the evaporation makeup water for the processing tank of the automatic developing machine. Namely, the decrease of the photographic density and the generation of precipitate are resulted when the distilled liquid is reutilized in the case of the execution of the evaporation concentrating under the reduced pressure if the formaldehyde exists in the waste photographic processing liquid. This waste stabilizer may be alone or may be a waste photographic liquid mixture mixed with other waste photographic liquids in such a case. The higher effect of the stabilizer is exhibited by incorporating at least one kind of the compds. selected from formula I, formula II, etc., into the stabilizer. In the formulas, R1 to R6 denote a hydrogen atom or univalent org. group; R7 to R9 denote a hydrogen atom or methylol group.

Title: Rear wheel steering control device for vehicle
Inventor: ICHIMARU HIDENORI
IPC: B62D7/15
Filed: 1985-07-22
Abstract: PURPOSE:To prevent the transverse slip of vehicles and ensure the small turning radius thereof to an available level by determining a steering ratio depending upon the slippery condition of a road surface and determining a rear wheel steering angle correspondingly. CONSTITUTION:A detecting means 5 for a road condition finds a slip condition attributable to the wetted and frozen road surface, and outputs a corresponding signal. Then, according to said detected signal and another signal from a car speed detecting means 1, a steering ratio operating means 2c calculates a primary steering angle ratio when the road is in a non-slippery condition, and a secondary steering angle ratio when the road is in a slippery condition. The result of the calculation is fed to an output means 3 as a determined steering angle ratio. And a control signal corresponding to the determined steering angle ratio, is outputted to a rear wheel steering mechanism 4 to set a rear wheel steering angle to the determined steering angle ratio. The secondary steering angle ratio in this case gives a steering value in the same phase as the front wheel at a relatively slow running speed, as compared with the primary steering angle ratio. Therefore, even when a coefficient of friction between the road surface and the wheels is small, the slip angle of vehicles does not become so large, thereby preventing a transverse slip and keeping the small turning radius as original.
