Title: Thin film transistor and its manufacture
Inventor: MAKITA NAOKI
IPC: H01L21/316
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To control the fluctuation of the threshold voltage of a thin film transistor by offsetting the influences of two insulating films on an active layer by making the overall polarity of fixed charged contained in one of the two insulating films holding the active layer in between from the top and bottom sides opposite to the overall polarity of the fixed charges contained in the other. SOLUTION: A base film 2 composed of silicon oxide is formed on a glass substrate 1 by performing the sputtering method in a mixed gas of argon and oxygen by using a quartz target so as to give negative fixed charges to the silicon oxide film 2. Then an amorphous silicon film is formed by the low- pressure CVD method and, after crystallizing the amorphous silicon of the film by irradiating the film with laser light, a crystalline silicon film 9 constituting an active area is formed by removing unnecessary parts. In addition, a silicon oxide film is formed so as to cover the crystalline silicon film 9 as a gate insulating film 10. After the film 10 is formed, positive fixed charges are given to the film 10 by performing annealing in an inert gas atmosphere.

Title: Sodium-sulfur battery
Inventor: KAGAWA HIROSHI
IPC: H01M10/39
Filed: 1983-02-09
Abstract: PURPOSE:To restrict the outflow of Na when an outer container that is a negative electrode component body is destroyed and improve the safety of the titled battery by providing a gap between the inner and outer containers that are the negative electrode component body and forming sealing structure and then making the pressure of the gap filled with inert gas higher than that of the inner container. CONSTITUTION:This Na-S battery is comprised by sealing a gap between an inner container 8' that fills Na and an outer container 9' that covers the inner container 8' and inserting a negative electrode component body that fills inert gas in the gap in a Na conductivity solid electrolytic tube 1 with the bottom. In this case, the body can be filled with the gasifying material that is thermally decomposed at temperatures below or exceeding the battery operating temperature and that discharges inert gas instead of inert gas. In addition, the maximum gas pressure P1 within the gap between the containers 9' and 8' is set higher than the maximum gas pressure P2 in the container 8'. When a crack is generated in the tube 1 by accident and the container 9' is perforated, the inert gas in the gap is discharged into the gap between the tube 1 and the outer surface of the container 9'. Since this gas pressure is higher than that of the inner part of the container 8', the supply of Na is stopped through a Na connecting path 10.

Title: Four wheel steering device for vehicle
Inventor: KANAZAWA HIROTAKA
IPC: B62D6/00
Filed: 1984-02-08
Abstract: PURPOSE:To eliminate an understeering characteristic generated in a vehicle, by decreasing a rear wheel steering ratio when a lateral acceleration detected by a lateral acceleration sensor exceeds a predetermined acceleration. CONSTITUTION:During a vehicle runs at an extremely los speed, the urging force of a spring 20c disposed in a steering angle regulating device 20 is set larger than the urging force of a return 14e due to operation of an actuator 20d. Therefore, a piston 20b is difficult to move outward even though hydraulic pressure is effected in an oil chamber 20a, and oil discharged from a front cylinder 7 is fed through a same/reverse phase changeover unit 16 to cylinders 14, 15 so that rear wheels are operated in the reverse phase direction to effect a small sharp turn of the vehicle. As the vehicle speed is increased, the urging force of the spring 20c is decreased since the actuator 20d is controlled by a controller 23, and therefore, variation in the volume of the rear cylinder is decreased by the front cylinder 7 to change the steering ratio in its decreasing direction.

Title: Semiconductor multi-layered film
Inventor: KASAHARA KENICHI
IPC: H01S5/00
Filed: 1990-01-30
Abstract: PURPOSE:To reduce optical absorption loss with a high reflectance kept unchanged by specifying the thicknesses of first and second semiconductor films in a semiconductor multi-layered film. CONSTITUTION:There are provided an n type semiconductor multi-layered film 31, an active layer 33, and a p type semiconductor multi-layered film 32. Predetermined optical wavelength in the semiconductor multi-layered films is assumed to be lambda, with the thickness of the first semiconductor film 31 being larger than lambda/4 and the thickness of the second semiconductor film 32 being smaller than lambda/4, and with the rate of changes in the film thicknesses from lambda/4 being the same order. Namely, even if high and low reflectivity semiconductor films 31, 32 are slightly displaced from lambda/4 thickness, the whole reflectance is not reduced steeply, and even if one semiconductor film is increased in its thickness, the degree of reduction of the reflectance can be decreased provided the other semiconductor is reduced in its thickness in the same degree. Accordingly, the thickness of the semiconductor film 32 with greater optical absorption loss is reduced relatively to that of the semiconductor film 31 with less optical absorption loss. Hereby, with high reflectance kept unchanged, the optical absorption loss in the semiconductor multi-layered film is reduced for improvement of the efficiency.

Title: Removing method for electronic part
Inventor: KONNO MASAHIKO
IPC: H05K3/34
Filed: 1993-01-14
Abstract: PURPOSE:To prevent the generation of projecting solder remains surely in a removing process of electronic parts from a board. CONSTITUTION:First of all, flux is applied to the lead wires 34a of an electronic part 34 to make the wettability of solder 35b better. Next, a beam is emitted on a pad 35a for heating. After the solder 35b is melted by the heat, the electronic part 34 is removed from a board 35, and solder 35b projections generated by drawing out the lead wires 34a are leveled evenly by applying vibrations to the board 35 emitting the beam continuously. As a result of this, it becomes possible to keep the electronic part 34 in a specified posture without deforming its lead wires 34b, since the solder 35b protrusions are leveled evenly, when the electronic part 34 removed from the board 35 is returned again on to the board 35 by lowering a vacuum pad 50, and when a mount unit 60 touches the electronic part 34 on the board 35 to suck and transfer the electronic part 34 on the side of an NG buffer 61.
