Title: Control circuit of dc-dc converter
Inventor: YAMASHITA TAKASHI
IPC: H02M3/28
Filed: 1986-10-20
Abstract: PURPOSE:To enable a DC-DC converter to continue stable operation though the transfer characteristic gets degraded, by connecting each light receiving element in series by the use of two sets of photocouplers to a control circuit of the DC-DC converter. CONSTITUTION:A DC input 1 is turned on and off by a main switch 4 driven by a drive circuit 3. The AC voltage thus generated is transformed 5, rectified and smoothed 6, and outputted into a load 7. This output voltage is divided by resistances 8 and 9 for comparison with reference voltage 11 to radiate the first luminous element 13 in response to its output (a). To a light receiving element 20 corresponding to the luminous element 13 a light receiving element 19 against the second luminous element 21 is connected in series, the voltage (b) at the contact of which is compared with the output (c) of a sawtooth wave oscillator 16 by a comparator 15. The operation of a drive circuit 3 is controlled with the output (d) of a comparator 15. Even if the transfer characteristic of a photocoupler is thereby degraded by radioactive rays, etc., no voltage (b) at the contact of the first and second light receiving elements 19 and 20 is changed and normal operation is carried out. It is therefore suitable for use on a satellite.

Abstract: PURPOSE:To obtain lighting beams having the spread of the incident angle bf beams sufficient even in the tangential direction or radial direction of circular slit lighting by turning spot lighting having an optical axis parallel with a shaft for scanning and mounting a filter equalizing the beams. CONSTITUTION:Beams 21 emitted from a light source 20 are condensed by an auxiliary condenser lens 23a in the front while beams reflected by a spherical reflecting mirror 22 in the rear are also added, and diaphragmed by a lighting field stop 24a, and the image of a light source is formed at the position of an aperture diaphragm 26a. Beams are further condensed onto the lower surface of a mask 28 by a condenser lens 27a, and lighting is conducted. Since an image by the condenser lens 27a for the light source is shaped at the point at infinity, lighting irregularities are not generated on the surface to be lit, the image of the field stop 24a is formed on the lower surface of the mask 28, and the contour of a lighting visual field is defined, and a lighting spot 29 is generated. An illuminating optical system is rotated and scanned together with a rotary casing 31, and the mask 28 is linearly scanned in the direction of D, and lighting is attenuated at the rate of cos alpha in the periphery by a illuminance correcting filter 30. Accordingly, lighting uniform extending over the whole surface can be obtained on the mask 28.

Title: Production of interior furnishing
Inventor: KODAMA MASAHIRO
IPC: B32B27/10
Filed: 1988-09-30
Abstract: PURPOSE:To obtain an interior furnishing by simple drying or without drying by bringing a porous body impregnated with a polyisocyanate into contact with an alcohol to thereby convert the polyisocyanate into a high-molecular reticular compound and mold it into a predetermined shape. CONSTITUTION:A porous body (e.g., flexible polyether polyurethane foam sheet) is impregnated with a polyisocyanate (e.g., 4,4'-diphenylmethane diisocyanate) and is brought into contact with an alcohol (e.g., ethanol or ethylene glycol) to convert the polyisocyanate into a high-molecular reticular compound and simultaneously mold this porous body into a predetermined shape. Thus it is possible to produce interior furnishings such as automobile ceiling materials, door trims and rear parcels in good productivity, because the drying is very easy when the alcohol is a lower alcohol, which is still more volatile than water, and because the alcohol itself is incorporated into the cured polyisocyanate product when it is a higher alcohol, which makes the drying unnecessary.

Title: Semiconductor memory sound recording an reproducing device
Inventor: TANIGUCHI HIRONORI
IPC: G10L19/00
Filed: 1989-09-25
Abstract: PURPOSE:To eliminate the generation of a voiceless period in the beginning of reproduction by starting sound recording operation on condition that a voiced/ voiceless decision part detects whether or not there is an input signal. CONSTITUTION:The voiced/voiceless decision part 5 inputs a vice signal passed through a preamplifier 2 to decide whether the signal is a voiced or voiceless signal, and inputs the result to a CPU 6. The CPU 6 inputs the output of the voiced/voiceless decision part 5 and starts executing a program for sound recording on condition that the decision part 5 generates a voiced sound detection signal. Namely, even if a sound recording start command is supplied by switch operation, sound recording operation is not started until the decision part 5 detects whether or not there is the input signal. Consequently, a voiceless period is prevented from being generated in the beginning of reproduction.

Title: Preparation of halftone data for laser plotter
Inventor: YAMANE KENJI
IPC: H04N1/053
Filed: 1988-10-04
Abstract: PURPOSE:To minimize the correction of a scanning system and thereby obtain a highly accurate print easily at low cost by setting a halftone density in a subscan direction so that the frequency component of a halftone period close to the error period of the scanning system is minimized and setting the density of the whole halftone at a halftone density in a scan direction. CONSTITUTION:The time at which a scanning error occurs is determined and it is decided which period of the halftone frequency component the error occurred is closet to. In addition, a halftone density is determined so that the frequency component close to the scan error is minimized. If the density is determined, it is fixed as it is in a subscan direction where the error exists, and halftone data is prepared so that the density of the whole halftone to be output to the surface of a recording member is changed by a halftone density in another scan direction. The frequency component of the halftone becomes zero depending on the halftone density. It is possible to judge to which period of a halftone frequency component the period of scan error is close. Consequently, it is possible to determine a density at which the frequency component of a halftone close to the period of scan error becomes zero. Thus humming due to a scan error and its relative halftone can be eliminated.

Title: Power supply
Inventor: KARIZUME IKUO
IPC: H02M1/12
Filed: 1990-09-19
Abstract: PURPOSE:To make it possible to improve the wave-form of an AC input current through simple circuitry by providing a switching element which turns ON, OFF so that DC supply voltage is made constant and an input current proportional to the input voltage from an AC input power supply is obtained. CONSTITUTION:Upon abrupt decrease of a load 13, load side output voltage Vo increases. Increase of Vo is detected through a control circuit 13 which then shortens ON interval Ton of a switching element. Consequently, Vo drops to maintain the load side voltage Vo at a constant level. When Ton is shortened, energy to be fed from a tank capacitor 6 through an output transformer 9 to the load decreases and thereby the voltage Vo to be applied on the tank capacitor 6 increases. But, since the energy to be stored in an input transformer for injecting energy into the tank capacitor 6, per single Ton, also decreases due to shortening of Ton interval, energy to be fed to the tank capacitor 6 decreases thus stabilizing the Vo. Furthermore, Io also decreases due to reduction of the Ton interval.

Filed: 1994-10-14
Abstract: PURPOSE: To obtain an effective interface by providing an integrated circuit which operates with a low-voltage and a high-voltage input signal and outputs a high-voltage or low-voltage signal corresponding to them. CONSTITUTION: Cutoff circuit block 4 inhibits a 1st amplifying circuit block 2 from becoming conductive when a high-voltage output terminal operates as an input terminal. Consequently, any high-voltage signal applied to the high- voltage output terminal B operates on only a 2nd amplification block 3. A 2nd amplifying circuit block 3, on the other hand, consists of a power element which operates with a high voltage, withstands high-voltage input, and outputs a low-voltage signal. For the application of this interface circuit 1 to an industrial control unit, the 1st amplifying circuit block 2 operates relatively to an actuator, but the 2nd amplifying circuit block 3 operates relatively to a microcontroller. This block 2 can be powered directly by the same power source with the actuator and the block 3 can share a low-voltage power source with the microcontroller.
