Title: Semiconductor radiation detecting device
Inventor: NARUSE YUUJIROU
IPC: G01T1/24
Filed: 1980-12-22
Abstract: PURPOSE:To compensate degradation of sensitivity due to the radiation damage of a semiconductor sensing part, by simultaneously, measuring the radiation by using a plurality of the semiconductor detecting parts having different thicknesses, and comparing the output signals from said semiconductor detecting parts. CONSTITUTION:A detecting element 1 is thinner than a detecting element 2 in thickness, and absorbes only the samll quantity of the radiation. Therefore the element 1 is hard to be damaged, and the curve of the signal A is flat in comparison with that of the signal B. A sensitivity ratio A/B is obtained from a dividing circuit 4. Then a compensating constant C is outputted from a compensating constant generator 5. The output of the detecting element 2 is compensated by said compensating constant C, and the irradiated dosage rate is displayed by a dosage rate display 7. In this constitution, the sensitivity compensation before the measurement in order to check the radiation damage of the semiconductor detecting element can be omitted.

Title: Electrostatic spray gun device
Inventor: GUSUTABU SUTANRI REBUI
IPC: B05B5/025
Filed: 1981-11-16
Abstract: A hand manipulable spray gun has an air turbine (37) which is driven at high speed in the order of 60,000 rpm and drives directly an alternator (38) to generate an alternating voltage in the order of 50 volts at about 1000 Hz. The output of this alternator is supplied to a step-up transformer (39) to achieve a secondary voltage in the order of 2500 volts. From here, it is supplied to a long chain series voltage multiplier (40) to increase the voltage thereof to one in the order of 55-80 kilovolts. The combination of a relatively small transformer and small capacitance of capacitors (71 to 77) in the voltage multiplier (40) establishes a direct voltage output from the voltage multiplier which has an alternating voltage ripple in excess of fifteen percent. The gun has a "wrap" efficiency comparable to 75 to 125 kV systems without the danger of using high direct voltages.

Title: Self-diagnostic device of anti-skid control device
Inventor: OZAKI YUJI
IPC: B60T8/88
Filed: 1993-07-23
Abstract: PURPOSE:To prevent vehicle wheels from being placed in their locked state by providing an unconditional self-diagnostic means which performs the self- diagnosis of an anti-skid control device regardless of whether at the braking or not, when the vehicle speed reaches a given preset value. CONSTITUTION:Anti-skid control is performed by implementing a program memorized beforehand in a memory device based on wheel speed detection values WFL to WRR from wheel speed sensors 11FL to 11RR. Concretely, a simulated vehicle speed Vref is calculated through wheel speed detection values of WFL to WRR. For instance, the difference between the simulated vehicle speed Vref and each of wheel speed detection values WFL to WRR is used for calculating each wheel speed which comes in within a given slip ratio. The braking power to each wheel is controlled by increasing or decreasing an operating liquid pressure to each of wheel cylinder 10FL to 10RR so as to achieve this wheel speed. Thus, edge wheel is securely prevented from being locked while sufficient deceleration speed is obtained.

And since the liquid crystal display elements have the quality of birefringence, the straight polarizing light face of the luminous flux is made to rotate to emit in propotion to the video signal after a round trip in the elements. The strainght polarizing light of the respective components are composed during retrograding through an optical path and emitted from the projection face 11a of the color separation optical system 11, and meanwhile the components obtained by rotating the polarizing face by 90 deg. against a projected light passes through the polarization BS 21 to be projected on a screen 25 by a projection lens 24.

Filed: 1980-12-23
Abstract: PURPOSE:To exercise high-precision, high-stability temperature control by leading a sensor signal to the earch during a positive-half-cycle period when the sensor signal has distortion. CONSTITUTION:A positive-cycle-pulse generating circuit 19 which generates a pulse Vp during a positive-half-cycle period and a grounding circuit for a sensor signal which is turned on by the pulse Vp and composed of a switching transistor (TR) 20 are added. A TR18 normally turns off and the collector current of the TR8 is integrated in a capacitor 10, but when the circuit 19 generates the pulse Vp, the TR20 turns on to ground the collector current of the TR8. Namely, a sensor signal is grounded during the positive-half-cycle period when the sensor signal has distortion. Consequently, an accurate temperature signal irrelevant to whether a heater is powered up or not is obtained, and thus high- precision, high-stability temperature control is exercised.
