Patent JP-S57176343-A (JP)
Title: Piston
Inventor: MATSUI ISAO
IPC: F16J1/24
Filed: 1981-04-21
Abstract: PURPOSE:To circumferentially rotate a piston and largely improve its lubrication, by converting movement of gas in a combustion chamber into rotary motion of the piston through elements and providing said elements to a top part of the piston provided with a ball joint to its pin part. CONSTITUTION:Hollows 2, with directivity, are provided on a top part of a piston 1, internally provided with a ball joint, and this hollow 2 is used as an element converting movement of gas into rotary motion of the piston. If movement as shown by an arrow head 3 is caused in gas in a combustion chamber, the element 2 catches to convert the movement into the rotary motion of the piston. For the gas movement, a swirl or jet stream of combustion gas from a subchamber to a main combustion chamber can be utilized.

Title: Automatic power control circuit
Inventor: SUGAWARA YOJI
IPC: H03G3/30
Filed: 1988-03-14
Abstract: PURPOSE:To decrease the current flowing to a differential amplifier in the standby state by inserting a 2nd resistor and a switching transistor(TR) turned on/off in the standby and in the operation between a 1st resistor and earth. CONSTITUTION:The 2nd resistor R2 of a high resistance and a switching TR T3 turned on/off in the operation and standby are inserted between a resistor R1 and ground at the emitter side of a differential amplifier and since the TR is turned on, the 1st resistor R1 is connected to ground and the circuit acts like a normal operation. When the TR is turned off in the standby, the 1st resistor R1 and the 2nd resistor R2 of a high resistance are inserted in series between the emitter of the differential amplifier and ground and the current flowing therethrough is very less. Thus, the discharge time of the battery being the power supply slows down.

Title: Flash illuminator
Inventor: NAGASAWA KIYOTO
IPC: G03B15/03
Filed: 1978-05-20
Abstract: PURPOSE: To elongate the illumination time of flash lamps by shifting the illuminating timings of the lamps so that the illuminatiom time periods may be partially overlapped.  
     CONSTITUTION: When a copy 1 left unfixed is conveyed by conveyor means 1, the fixation is accomplished in a manner to absorb the light emitting energies of flash lamps 4 and 5 within a flash fixing device having a reflecting plate 3 and the lamps 4 and 5. The illuminating timings of the lamps 4 and 5 are determined by the timings at which light emitting signals F 1  and F 2  fed from a light emitting signal generating circuit FG to trigger generators TRI 1  and TRI 2 . The circut FG is composed of detecting means 6 and a delay circuit so that it generates with a timely shift the signals F 1  and F 2  in response to the detection of the copy 1 by the means 6. Thus, it is possible to obtain an excellent fixing property.

Title: Transmission method for facsimile broadcast
Inventor: HASEGAWA MASAAKI
IPC: H04J3/00
Filed: 1990-03-12
Abstract: PURPOSE:To attain reception recording with high resolution for a receiver coping with high resolution and reception recording with low resolution for a receiver coping with low resolution by dividing high resolution picture information into plural low resolution picture information divisions, compressing each division and sending them in time division. CONSTITUTION:When picture information 1 with high resolution is sent, picture information with high resolution is divided into plural sets of picture information with low resolution, divisions 3a-3d are sent in time division. Thus, the plural divisions 3a-3d received and decoded are synthesized by a high resolution oriented receiver and one of the divisions 3a-3d is decoded by a standard resolution oriented receiver to attain reception recording. Thus, picture information is received and recorded with a resolution in response to each function even in the case of the receiver having high resolution reception capability or the receiver having standard resolution reception capability.

Title: Gas laser oscillator
Inventor: UCHIDA YUTAKA
IPC: H01S3/038
Filed: 1987-03-18
Abstract: PURPOSE:To avoid the deterioration of gas laser medium circulation and the complexity of its structure and to enable preliminary ionization effectively by dividing at least one of cathode and anode which form main discharge electrode into a plurality of sections laterally to perpendicularly cross a longitudinal direction, and using at least one of a plurality of sections as preliminary ionization electrode used also as a main discharge electrode. CONSTITUTION:Charging energy charge in a main capacitor 4 is charged in each peaking capacitor 24 by the closure of a switch 5. Thus, discharge takes place concentratedly at a position near the opposed surfaces of cathodes 20 disposed near, between the divided two sections 23a, 23b laterally of electrode pieces 22a, 22b,..., of the cathode 20. Gas laser medium between the electrodes 20 and 21 is preliminarily ionized by ultraviolet light produced by the discharge. When the preliminary ionization is sufficiently advanced and a potential across the capacitor 24 exceeds the breakdown voltage of main discharge, the main discharge takes place between one section 23a of the electrode pieces 22a, 22b,..., of the cathode 20 and the anode 21, and a light output laser is stably oscillated.

Title: Thermistor element and manufacture thereof
Inventor: KAWAGUCHI YUKIO
IPC: H01C7/02
Filed: 1990-03-13
Abstract: PURPOSE:To prevent the deterioration of characteristics under adverse conditions such as high temperature and humidity, and improve reliability, by coating only the parts, of leads, exposed from the glass with a plated film. CONSTITUTION:Plated films 431, 451 are formed only on the parts of leads 43, 45 which parts are exposed from glass 5, and the surfaces of the leads 43, 45 are directly in contact with the glass 5. Since a plated film, whose wettability to glass is low, is not interposed, the adhesion between the leads 43, 45 and the glass 5 are increased, As a result, when the device is used under the condition of high temperature and humidity, water content, oxygen, etc., scarcely permeate into the inside of the glass-sealed part, and thermistor characteristics are not deteriorated. Activation treatment of the lead surface, which is performed to improve the adhesion of the plated film, is executed after glass-sealing, so that chemicals used in the case of activation treatment do not remain in the glass-sealed part, thereby preventing the deterioration of leads, electrodes, etc.
