Title: Voltage conversion device
Inventor: NAKAMURA KAZUTO
IPC: H02M7/12
Filed: 1990-06-20
Abstract: PURPOSE:To improve a conversion efficiency by chopping an AC power source voltage in a short period, inverting the polarity of a magnetic flux generated in a transformer at each chopping, full-wave rectifying an induced voltage, and enhancing a conversion frequency in the transformer. CONSTITUTION:A power source voltage V1 is chopped in a high frequency, and the polarity is inverted at each pulse. As a result, an output voltage (primary voltage of a transformer 4) V1 to the transformer 4 is converted to a pulselike high frequency voltage having the same envelope as the waveform of the power source voltage. The primary voltage V1 of the transformer 4 is stepped down by the transformer 4, and then full-wave rectified by a rectifier 5. However, the frequency of the primary voltage is increased to suppress the maximum magnetic flux density to a small value.

Title: Cmos inverter circuit
Inventor: OKANO YOSHIAKI
IPC: H01L27/092
Filed: 1985-07-24
Abstract: PURPOSE:To decrease the delay in leading and trailing of a CMOS inverter circuit by increasing or decreasing a resistance of a p-channel transistor (TR) than the resistance of a n-channel TR. CONSTITUTION:The resistance of the p-channel MOS TRs TR1, TR5 is increased more than that of the n-channel MOS TRs TR6, TR2 to bring an input threshold voltage to Vcc/2 or below. When the level of an input IN changes from H to L, an output (b) of the p-channel side inverter rises from L to H, but the leading is unsharpened. An output (c) of the n-channel side inverter rises also from L to H, the level is boosted by the leading of the output (b), the back gate effect is acted on the TR2 to quicken the leading of the output (c). The outputs (b), as above are received by CMOS inverters TRs3, 4 of the next stage, the turn-on of the n-channel TR4 is quickened by the output (c) especially and not too much delay is caused for the leading/trailing at an output OUT.

Title: Fuel supply control device of engine
Inventor: MASUDA TOYOO
IPC: F02D41/00
Filed: 1984-08-03
Abstract: PURPOSE:To eliminate a lock when power is cut off and enable a throttle valve to be reset, by actuating a relay in a throttle valve motor circuit when all of the brake switch, throttle backup switch and the accelerator idle switch are simultaneously closed. CONSTITUTION:When a vehicle is stopped by depressing a brake pedal, a brake switch 6, throttle backup switch 7 and an accelerator idle switch 8 are turned on, and the switches 6-8 detect a trouble in an electronic control device 4 becuase a throttle valve is not turned in the direction of its full close position despite that the speed of an engine decreases. Accordingly, a control device, receiving voltage of an ignition circuit and urging a relay coil 5b in a relay 5 so as to open a relay switch 5a and deenergize also a coil 2b, stops a motor 3 by opening a switch 2a so as to cut off voltage to the motor 3. Consequently, the engine is driven in operation of an idling mode by returning the throttle valve to its full close position by a return spring.

Title: Optical coupling device
Inventor: SUGAWARA MITSURU
IPC: G02B6/42
Filed: 1986-07-14
Abstract: PURPOSE:To eliminate the position shift at the time of fixation by adjustment after the fixation and to make the adjustment without contacting by holding either of a photosemiconductor element and an optical element on a base through shape memory alloy and fixing it by soldering, etc., and then giving temperature variation to the shape memory alloy member. CONSTITUTION:A semiconductor laser element 1 is driven after the assembly of respective elements and the quantity of light coupled with an optical fiber is monitored on a power meter 12 connected to the other terminal of the optical fiber. One shape memory alloy member 7 is irradiated with laser light guided from an externally provided light source 13 through the other optical fiber 14 and the member restores itself to the shape memorized at high temperature when the temperature is raised up to martensite transformation point, so the semiconductor laser element moves. In this process, variation on the power meter is read and the irradiation of the laser light is stopped at the best position. When the laser element is moved in the opposite direction, the other shape memory alloy member 9 is only irradiated with the laser light. This operation is repeated to adjust the position relation between the semiconductor laser element 1 and optical fiber 4 without contacting.

Abstract: PURPOSE:To obtain more precise particle size distribution by correcting an error generated in accordance with the concentration of particles in a centrifugal force field. CONSTITUTION:An output signal from a photodetector 5 detecting light B projected from a light source 4 and passed through a rotating case 1 is inputted to a CPU12 every fixed period in accordance with a measuring program previosuly stored in a ROM11 and stored in a RAM15 sequentially, and simultaneously, time (t) after the start of application of centrifugal force corresponding to said signal input is converted into a particle diameter DP by the CPU12 on the basis of the formula stored in the ROM11 and the converted value is stored in a RAM15.
