Title: High voltage switch
Inventor: YABUUCHI MASATAKA
IPC: H01S3/097
Filed: 1992-06-29
Abstract: PURPOSE:To simplify the constitution of a high voltage switch which uses many electric power semiconductor devices such as FET and IGBT and turn on the switch at a high speed. CONSTITUTION:Only the bottommost level FET 1 is turned on/off by a gate drive circuit 7 and other FETs are supplied with gate current in synchronism with the gate drive circuit 7 by a separately provided gate power source capacitor 9. Therefore, the gate drive circuit 7 does not have to be provided for each FET 1, power source supply for driving the FETs 1 in series is eliminated and all the FETs 1 that constitute a high voltage switch are turned on at one time at a high speed only by giving the on-instruction to the bottommost FET 1. Since the number of the components is reduced, the switch is manufactured at a low cost.

Title: Sheet cutting device
Inventor: KAWAKAMI NOBORU
IPC: B26D1/38
Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To lubricate the cutter tips without changing the occupation section area of a sheet cutting device by furnishing a lubricant-containing resilient piece, to be pressed by the cutter tip of a rotary blade when it rotates in swinging, in a part of a stationary blade in the range of engaging of the stationary blade tip with the rotary blade tip where the sheet material does not pass. SOLUTION: When the cutter tip 21 of a rotary blade sinks to the downmost position relative to the cutter tip 11 of a stationary blade, the rotary blade tip 211 in the range 9 where the two cutter tips 11, 21 are in direct engagement with each other, is in the pressed condition to such a degree as deflecting concave a resilient piece 6 to 1-2 mm approximately, and lubricant contained in this resilient piece 6 will be applied automatically to the cutter tip 211 of the rotary blade. At the second run of cutting operation, the lubricant will be applied also to the stationary blade tip 111 when the rotary blade edge 211 with lubricant is applied is engaged by the cutter tip 111 in the range where the cutter tips on the stationary blade 1 side are engaged by each other directly.  Because the lubricant is spread thinly on the cutter tip line, propagation of tip wear due to direct engagement of cutter tips with each other will be suppressed.

Abstract: PURPOSE:To obtain the optically active phase difference plate which is thin and has excellent light transmittance by providing vapor-deposited layers consisting of a double refractive material on a light transparent substrate and forming the vapor-deposited layers with the superposed layers of the layers which vary in orientation direction. CONSTITUTION:The light transparent substrate 2 is disposed diagonally with a vapor deposition source having the double refractive material 1 and a vacuum vapor deposition is executed under the continuous or intermittent rotation of the light transparent substrate 2 to form the superposed layers 11 to 14 of the vapor-deposited layers which vary in the orientation direction on the light transparent substrate 2. The orientation direction can be controlled by rotating the light transparent substrate 2 at this time and the superposed layers 11 to 14 of the vapor-deposited layers which are different in the orientation direction are formed. The superposed layers 11 to 14 of the vapor-deposited layers formed in such a manner vary in the orientation direction and, therefore, exhibit the optical rotatory power and since these layers are the vapor-deposited layers, the layers are excellent in small thickness and light transmittability.

Title: X-ray waveguide method and optical fiber used for said method
Inventor: HIDAKA TATSUHIKO
IPC: G02B6/02
Filed: 1984-08-16
Abstract: PURPOSE:To reduce the size of a device by guiding X rays to a hollow optical fiber which has a hollow part in the center, and guiding the X rays through the hollow part. CONSTITUTION:The hollow optical fiber 3 for X-ray guidance has the hollow part in the center of a fiberous solid material such as quartz, and X rays from an X-ray source 1 are reflected totally by this hollow part and guided. Thus, the optical fiber 3 is hollowed in a vacuum state, so when X rays are admitted into this hollow part, the X rays are guided while reflected totally and repeatedly in the hollow part. Further, the hollow optical fiber 3 is flexible, so the radiant X rays from the X-ray source 1 are guided through the hollow optical fiber 3 to an optional position efficiently. Consequently, the conventional restriction conditions of X-ray utilization, i.e. need to array the X-ray source, a filter or shutter, an object of irradiation, an X-ray detector, etc., linearly is eliminated completely, thereby reducing the size of a device which utilizes X rays.

By eliminating, with a reactive sputter etching system, the SiO2 film 4 in the region where an Si3N4 film 11 is eliminated, an emitter forming region 18 can be formed. A base layer 19 is formed by ion implanting method. A polycrystal silicon film is stuck on the whole surface, and phosphorus for forming an emitter layer is ion-implanted. An emitter layer 21 is formed by heat-treating.
