Patent JP-H0887995-A (JP)
Title: Organic electrolyte battery
Inventor: FUKUNAGA TAKAO
IPC: H01M2/16
Filed: 1994-09-14
Abstract: PURPOSE: To prevent complete melting or melting cracks on shutting off of current by using a stacked structure body of a polyolefin porous body and a polyphenylene sulfide porous body as a separator of an organic electrolyte battery. CONSTITUTION: A separator 3 placed between a positive plate 1 and a negative plate 2 of, for example, a lithium ion battery is formed by integrally stacking with hot roll compression a microporous film of polyolefin such as polyethylene and a nonwoven fabric in a dry process of polyphenylene sulfide. When a battery generates heat by external short circuit and temperature rises to around melting point of the polyolefin, pores of the porous body are clogged by melting and current is shut off. The polyphenylene sulfide porous body with high heat resistance does not melt and acts as a supporter of the polyolefin porous body, and progress of contraction or breakage is prevented. Polyphenylene sulfide has high chemical resistance to an organic solvent in an electrolyte.

Title: Tapered roller bearing
Inventor: UENO HIROSHI
IPC: F16C33/46
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a tapered roller bearing which can prevent the occurrence of bearing separation caused by biting foreign matters, and can lengthen the life of the bearing. SOLUTION: In this tapered roller bearing, both a second gap B between the small diameter side brim part 6 of a holding unit 5 and the small diameter side brim part 7 of an inner race 1, and a fourth gap D between the large diameter side brim part 12 of the holding unit 5 and the large diameter side end part 8 of the inner race 1, are set at a value enabling the holding unit 5 to stand close to the inner race as far as the holding unit is out of touch with the inner race 1 while the bearing is being rotated. In addition, a first gap A is made larger than the second gap B, and a third gap C is also made larger than the fourth gap D. When the flow rate of lubricant from the small diameter side to the large diameter side is made minimum, the occurrence of biting foreign matters carried in by lubricant can be prevented.  Besides, heat can be radiated from the gap A and the gap C without increasing the flow rate of lubricant from the small diameter side to the large diameter side.

Title: Cutting method of steel plate coated with primer rich in zinc
Inventor: MASUKO SHINKICHI
IPC: B23K7/00
Filed: 1984-11-26
Abstract: PURPOSE:To obtain a fine cut face of a steel plate coated with zinc-rich primer and improve the efficiency of the cutting work, by blowing compressed air to the vicinity of a cutting nozzle from the back of the cutting nozzle in its advancing direction. CONSTITUTION:A pipeline 6 connected with a compressed air source and supported by a bracket 5 fixed to a cutting torch 2 is put behind the torch. Two air blowing nozzle 8 are fitted to a holding member 7 provided at the lower end of the pipe line 6. The nozzles 8 are oriented toward the vicinity of the cutting location of a steel plate 1 and they are arranged in such a way that the blown air flows 9 from the nozzles 8 can be directed to both sides of cutting oxygen. When gas cutting is performed by advancing the gas-cutting torch 2, the compressed air of the nozzles are blown to the vicinity of the cutting torch 2 from the back of the torch 2. When such a method is applied, the cutting location and tip of a cutting nozzle 3 are cooled and no cutting slag adheres to the cut section. At the same time, the cutting nozzle 3 is prevented from clogging. Therefore, fine cut faces are obtained and, at the same time, the efficiency of the cutting work is improved.

Title: Automatic exposure control camera
Inventor: OOKUBO YUUJI
IPC: G03B7/089
Filed: 1983-12-27
Abstract: PURPOSE:To improve operability by locking exposure and turning off the power source at the same time only by pressing momentarily an AE lock button and thus preventing the power source from being held on by turning off simultaneously the power supply, and pressing the AE lock button only in display confirmation. CONSTITUTION:When the AE lock button is pressed in while a subject part is set in the center of a finder, a brush shifts in position from an area (a) to an area (b) and a switch SM is turned off. Then, an amplifier A4 is turned off through an AND1 and a diode D6. Namely, an AE lock is made. At the same time, a TRQ5 is turned off through a diode D5, transistor (TR)Q7, and resistances R14 and R13, so a TRQ8 turns off unless a switch SH is turned on, and consequently electric power is applied to neither a power source holding timer TI nor a bias circuit BI, so that biases to all amplifiers are turned off. Thus, problems of AE locking are solved and the operability is improved.

Title: Plasma vapor growth device
Inventor: TAKASAKI KANETAKE
IPC: H01L21/31
Filed: 1983-12-27
Abstract: PURPOSE:To improve the operating efficiency of a plasma vapor growth device and to enable a film to be stably formed, by applying to the device different high-frequency exciting conditions according to the differences of the processing conditions between during formation of the film and during cleaning of the device. CONSTITUTION:When contaminants on the walls of a bell jar are etched away by filling the device with Ar gas of an appropriate concentration, the etching rate (Angstrom /min) is increased proportionally to the frequencies. On the other hand, when a film is formed on a substrate by collecting plasma ion gas excited in the reaction gas space, the film formation rate is decreased within the frequency range of 1-3MHz, while in that range a film which not tensed nor compressed can be obtained. A dense film can be obtained in the compression stress region corresponding to the lower plasma frequencies as shown in the graph. According to such differences of the processing conditions, high plasma frequency of 5kHz or more is applied when the device is cleaned just before the formation of a film, and a plasma frequency of 1MHz or less is applied when the film is formed by vapor-phase reaction. In such a manner, an excellent thin film can be obtained efficiently.

Title: Control circuit of normal & reverse rotations for dc motor
Inventor: ITO HIROYUKI
IPC: H02P1/22
Filed: 1985-11-06
Abstract: PURPOSE:To prevent the motor from burning on account of the simultaneous switching-on of the switching elements by inputting the normal or reverse rotation signal through the Zener diode to the switching elements connected in series. CONSTITUTION:When an H signal is inputted to an input terminal MFS and an L signal to MRS, the transistors TR 2 and TR 3 are turned to 'ON' and the motor M operates reversely. On the other hand, when a signal L is inputted to the input terminals MFS and a signal H to MRS, the transistors TR 1 and TR 4 are turned to 'ON' and the motor M operates normally. The transistors TR 1 and TR 2 and TR 3 and TR 4 would not be turned to 'ON' simultaneously, because the Zener diodes ZD 1 - ZD 4 are connected to the bases of the transistors TR 1 - TR 4. Thus the transistors TR 1 - TR 4 can be prevented from burning.
