Title: Nighttime photographing device
Inventor: HASEGAWA MITSUO
IPC: G03B15/02
Filed: 1992-05-11
Abstract: PURPOSE:To photograph an object at a long distance at night by using a laser as a light source irradiating the object in the dark, performing two-dimensional scanning by a laser beam, opening a shutter as soon as the scanning is started, and closing the shutter with the finish of the scanning. CONSTITUTION:The laser beam emitted from a laser oscillator 1 is reflected by a galvano-mirror part 2 controlled in X-axis and Y-axis directions by a mirror control part 3. Since the angle of the galvano-mirror is changed with input voltage, the control part 3 optionally adds voltage inputted in an X-axis control part and a Y-axis control part so as to perform the scanning to an X-Y plane. A synchronizing control part 4 controls the opening/closing of the shutter of a camera 5 by synchronizing with time when the irradiation with the laser beam is performed. Namely, the shutter of the camera 5 is opened at a certain point in the middle of the irradiation with the laser beam and it is closed when the position of the laser beam reaches a next point, thereby realizing the photographing of the laser beam reflected from the object 7.

IPC: G01D5/245
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a detector for a steering angle whereby a rotational angle and a neutral point of a steering are detected with high resolution. SOLUTION: Magnetoresistive elements 2, 3 detect change of magnetic fluxes along with rotation of a magnetic ring 1 to output a plurality of sine waves having different phases. A rectangular wave group generating circuit 4 generates a plurality of rectangular wave groups having a phase the same as the sine wave and having a phase different from the sine wave on the basis of the plurality of the sine waves. An angle signal generating circuit 5 executes a logical operation by using the rectangular waves to generate two rectangular waves having cycles each sorter than its original rectangular wave of which phases are shifted with each other by one fourth of the cycle. A control circuit obtains a steering angle based on the two rectangular waves. A neutral point signal element 6 outputs a pulse having a width shorter than the cycle of the sine wave.  A neutral point detection signal generating circuit 7 executes a logical operation by using one or more rectangular waves in the rectangular wave group and generates a neutral point detection signal of the steering.

IPC: G01N30/20
Filed: 1981-07-27
Abstract: PURPOSE:To ensure higher quantitativity even when a gas reservior chamber or a gas  quantity detecting tube is negative in the pressure by feeding air into the gas quantity  detecting tube communicating to the gas reservior chamber to maintain the normal  pressure before the gas quantifying operation. CONSTITUTION:When a 6-way diverter valve 5 is normally retained at the state as  shown by the solid line while a transformer case 1 is filled with an insulating oil 2 deaired, a gas reservior chamber 4 and a gas quantity detecting tube 6 communicating  thereto is negative in the pressure. Under such a condition, before the measurement, an  air release valve 13 is opened to maintain the normal pressure in the gas reservior  chamber 4 and the gas quantity detecting tube 6 and the valve 13 is closed again. Then,  a gas circulator 12 is actuated to circulate gas forcibly between the gas reservior  chamber 4 and the gas quantity detecting tube 6 to uniformize it with an agitation.  Thereafter, a port of the 6- way diverter valve 5 is switched to the channel as shown  by the broken line to connect the gas quantity detecting tube 6 to a carrier gas input/ output tubes 10 and 11 whereby the gas is introduced into a gas chromatograph equipment 9. This eliminates changes in the peak output value caused by pressure in the  tube 6 due to a difference in the treatment conditions of the insulating oil 2.

Filed: 1992-04-10
Abstract: PURPOSE:To surely make lands conductive to each other by a method wherein a plurality of thin wires are inserted into a through hole and a solder which is absorbed by the capillary phenomenon of the thin wires is filled into the through hole. CONSTITUTION:A thin wire 9 is inserted into a through hole 6. A conductive material such as copper, aluminum or the like is used for the thin wire 9. A plurality of thin wires whose diameter is smaller than the diameter of the through hole 6 are inserted. Small gaps are formed between the thin wires 9 which have been inserted into the through hole 6; parts between the thin wires 9 are set to the state of capaillaries due to the gaps. After the thin wires 9 have been inserted, a printed wiring board 1 is immersed in a soldering tank. A molten solder which is kept at about 260 deg.C is filled into the soldering tank. When the board is immersed in the soldering tank, the molten solder creeps into the through hole 6. When the molten solder creeps, it is absorbed smoothly into the through hole 6 due to a capillary phenomenon between the thin wires 9. Thereby, lands can be made conductive without performing a complicated operation such as a soldering operation or the like.
