Title: Deep drawing method
Inventor: KAWACHI JIYOUSUKE
IPC: B21D22/20
Filed: 1979-09-27
Abstract: PURPOSE: To prevent the reduction of the wall thickness at the middle point of the blank, by impressing the compression force on the outer circumference of the blank so as to compress the blank toward the middle point between two punches, at performing the deep drawing work parallelly with two punches.  
     CONSTITUTION: The blank 17 is placed on the die 10 and is held by the blank holder 16. The elevator 14 is moved down in order to push down the punches 15A, 15B, for starting the purposed deep drawing work. With the progress of the drawing process, the pressure plate holders 21A, 21B, move forward; hereby, the external force is impressed on the blank 17 through the pressure plates 18A, 18B, so as to compress the blank 17 from the outer circumferential sides 17a, 17b. As a result, the materials in these outer circumferential sides 17a, 17b, are forcibly fed toward the middle point between two punches 15A, 15B. Hereby, the blank is prefectly deep drawn and is provided with simultaneously deep drawn plural parts without reducing the wall thickness of the middle part of the blank.

Title: Treatment of polysilicon powder
Inventor: SAITO MAKOTO
IPC: B09B3/00
Filed: 1991-04-26
Abstract: PURPOSE:To make polysilicon powder harmless in an easy and safe manner by stabilizing the polysilicon powder by a reaction with water in the presence of a surfactant, partially dehydrating the stabilized powder and forming silica by thermal decomposition. CONSTITUTION:Flammable, explosive and poisonous polysilicon powder produced as a by-product at the time of producing an amorphous silicon film, etc., is recovered and dispersed in a large amt. of water in the presence of a surfactant such as an anionic surfactant. By this dispersion, the powder is allowed to react partially with the water to reduce the activity. The resulting stabilized powder is partially dehydrated with a filter press, etc., and thermally decomposed in the air, etc., to form silica. Since the polysilicon powder is dispersed in the large amt. of water, the heat of reaction is absorbed and a complete reaction can be attained. Since the stabilized powder having a high water content is thermally decomposed, the thermal decomposition reaction can be allowed to proceed.

Filed: 1994-06-07
Abstract: PURPOSE:To perform optimum in-cabin sound field correction for variation in the temperature in a cabin by changing coefficients of an FIR filter for correction as the temperature in the cabin varies. CONSTITUTION:A signal which is inputted to a digital audio signal input terminal 11 is inputted to an FIR filter arithmetic part 12 for correction, converted to desired amplitude and phase characteristics, and outputted from a digital audio signal output terminal 13. An incabin temperature decision means 15 detects the temperature in the cabin and outputs it to a filter coefficient selecting means 14. The filter coefficient selecting means 14 selects one kind of coefficient stored in a filter coefficient storage unit 17 and informs a filter coefficient replacement unit 16 of it. The filter coefficient replacement unit 16 changes the coefficient of an FIR filter computing element 12 on the basis of the information. Consequently, the sound filed in the cabin can be corrected corresponding to variation in the in-cabin temperature.

Filed: 1986-06-02
Abstract: PURPOSE:To detect all peaks and bottoms of an output signal waveform by varying a threshold value according to variation in signal waveform when converting a fluorescence signal from a printed board into a binary signal. CONSTITUTION:The output signal S of a CCD detector 11 is converted by a signal binary-coding circuit 16 into a binary signal. The signal binary-coding circuit 16 consists of a delay circuit 17, a threshold value setting circuit 18, and a comparator 19. The threshold value setting circuit 18 inputs the output signal S of the detector 11, averages waveform values of specific ranges, and sets the threshold value Tv which varies according to variation in the waveform of the output signal S, and this setting circuit 18 consists of an amplifier 20, an averaging circuit 21, an adder 22, and an offset circuit 23. This threshold value setting circuit 18 sets the threshold value Tv which varies automatically according to the variation of the waveform of the output signal S shown by a solid line. A threshold value shown by a broken line crosses all peaks (a)-(f), and bottom (g) of the waveform of the output signal S, so all the peaks and bottoms of the waveform of the output signal S are detected in the binary-coded signal B.

Title: Pressure release structure of sealed type gas switch gear
Inventor: MITOMI KAZUMICHI
IPC: H01H33/575
Filed: 1987-05-25
Abstract: PURPOSE:To quicken a start of pressure release and to prevent arcs from being ejected outside by operating a pressure operation valve larger in its area than a pressure release plate so that the pressure release plate is pierced. CONSTITUTION:A pressure release plate 4 with prescribed mechanical strength and tenacity is mounted to cover a round hole 3 formed on a peripheral wall 2 of a switch gear 1. A pressure operation valve 11 is fixed to the peripheral wall with a desired gap through a holding valve 10 so that it faces the pressure release plate 4 in the switch gear 1. The pressure operation valve 11 is larger in its area than the pressure release plate 4, and it is deformed in the direction of the pressure release plate 4 by a gas pressure which is too small to break the pressure release plate 4, and next a claw 12 on the central part of the valve 11 is used to pierce the pressure release plate 4 and then break it. Since the gas is released before the gas pressure becomes too large on abnormal occasions such as a shorting accident, arcs are prevented from being ejected outside.

Title: Synchronous motor
Inventor: NISHIMURA CHISATO
IPC: H02K11/00
Filed: 1979-09-28
Abstract: PURPOSE:To expand a temperature range which a synchronous motor is used by a mechanism wherein a coil is wound in a shape that a coil winding portion is divided into the two layers of an inner layer and an outer layer, and a temperature sensing switch is connected to either one layer. CONSTITUTION:A coil 4 is wound in a shape that a coil winding portion is divided into an inner layer 4a and an outer layer 4b, and a temperature sensing switch 9 such as a bimetal is connected in series with the one side. The temperature sensing switch 9 functions at a fixed temperature T deg.C. The switch 9 is disconnected at T deg.C or more, and a condition is brought which currents flow through only one side of the inner and outer layers 4a, 4b. Consequently, the excitation of a magnetic pole tooth portion 1a is weakened, a decreasing portion of friction between a thrust washer 8 and a metal 5 is absorbed, and a range of stable rotation is returned to an approximate normal-temperature condition. Thus, a temperature range which a synchronous motor is used can be expanded.

Title: Two-stage unlubricated screw compressor
Inventor: OTA HIROSHI
IPC: F04C28/06
Filed: 1995-05-25
Abstract: PURPOSE: To feed dry air, containing no drain, to a two-stage compressor and to prevent drain from residing at the two-stage compressor after a stop by a method wherein when the compressor is stopped, after unload operation is forcibly effected for a given time, the compressor is stopped. CONSTITUTION: Compressed air the temperature of which is increased in such a way to be boosted by a one-stag compressor 1 is cooled by a cooler 3 (an intercooler). After the compressed air is compressed to a given pressure by a two-stage compressor body 2, it is discharged through a cooler 4 (a high precooler), a check valve 9, and a cooler 5 (an after-cooler). In which case, when an amount of using air is decreased and a pressure in a delivery piping is increased to a value higher than a given pressure, the increased pressure is detected by a pressure switch 10 to switch two three-way solenoid valves 12 and 13, a chamber A is pressurized, and an intake air throttle valve 6 is closed. Further, simultaneously, a gas release valve 7 is opened, and air in a delivery piping running between a compressor body and the check valve 9 is released (unloaded).  After unload operation is performed for a given time, the compressor is stopped.
