Title: Semiconductor device
Inventor: UEDA KAZUO
IPC: H01L21/52
Filed: 1980-08-09
Abstract: PURPOSE:To prevent alloying of Al and Mo in a large power capacity device and to improve reliability, by pressure welding an Al-layer formed on a semiconductor substrate and a Rh-layer provided through a metal layer such as Ag on an Mo plate to make it into an electrode. CONSTITUTION:For instance, in a rectifying device with a large aperture, an Mo plate 3 is bonded to one side (an Al-layer) of an Si wafer 1, wherein on both sides Al-layer 2 and 4 are formed, by soldering. With the other surface (an Al-layer 2) of said wafer 1 a Rh-layer 10, which is 0.05-0.8mum thick and plated on the 0.1- 0.3mm. thick Mo plate through an Ag-layer or an Ni-layer, is contacted to be made into a device of pressure welding and holding by being between the cupper block electrodes 6 and 7 and pressed from both sides. Thereby, the Mo plate 9 and the Al-layer 4 are alloyed due to the expansion and contraction when turning ON electricity preventing the generation of cracks on the wafer 1 and the fluctuation of power loss to highten the reliability of the device.

Inventor: GAMOU GOUTAROU
IPC: B23H7/06
Filed: 1979-08-30
Abstract: PURPOSE:To simplify a device named in the title, by using a coordinate value calculating circuit, etc. CONSTITUTION:A short-circuit detecting circuit 13, coordinate value accumulation circuit 14, coordinate value accumulation resistors 15 snd 16, calculation resistor 17, coordinate value calculation circuit 20, coordinate value resistors 18 and 19, linear interpolation device 21, discharge reopening circuit 22 are placed between a discharge limit circuit 6 and an interpolation device 8. In this set-up, when the short- circuit detection circuit 13 detects a short-circuit during discharge machining to a work 1 by a wire electrode 2, movement stop of the work 1 and voltage shut-off are effected and at the same time the work 1 is progressively moved in the X direction and moved in circle and the wire electrode 2 makes arc movement. During this movement coordinate values (values relative to the work 1) of the wire electrode 2 is read and accumulated. Further, number of readings is counted to calculate mean coordinate value of short circuit release points. Based on a calculated mean value, the work 1 and wire electrode 2 are moved to a mean coordinate value to be released completely from the short-circuit. Accordingly a resistor for memory of the passage of the wire electrode 2 one by one is not necessary.

Title: Fluid transmission gear with lock-up mechanism
Inventor: SHIBAYAMA NAOSHI
IPC: F16H45/02
Filed: 1990-04-26
Abstract: PURPOSE:To lower vibration by providing the plural numbers of spacer members on a circumference concentric with a circle for which fixing members are provided, letting the center of a line segment connecting the respective spacer members coincide with the rotating center of a cover member, and thereby letting respective angles, each of which is formed by adjacent 2 line segments extending from the center of the cover member to each nut member and each fixing member, are made different. CONSTITUTION:Each nut member 10 acting as a fixing member is provided on the circumference around the center of the rotating shaft of a converter cover 2 at positions by which a cylinder is equally divided by 3, and a pair of 2 spacers 17 is provided on the circumference while being symmetric about the center. The center of a line segment connecting the respective spacers 17 thereby coincides with the rotating center of the cover 2. Each spacer 10 which is dimensionally identical to each nut member 10 in the axial direction, is fusion bonded onto the cover 2 in such a way that the angles of alpha1, beta1, gamma1, delta1, and epsilon1, each of which is formed by adjacent 2 line segments extending from the rotating center to each nut member 10 and each spacer 17, are made entirely different, and intervals between each nut member 10 and each spacer 17 are concurrently made entirely different. This thereby causes the undulation of the cover 2 formed by the pressing action of a lock-up piston 8 to be unequal in space, thereby lowering the level of vibration.

Title: High speed thread winding machine
Inventor: YASUDA KAZUYOSHI
IPC: B65H54/52
Filed: 1985-05-24
Abstract: PURPOSE:To obtain more uniform and better physical property and form of a thread package being wound with increased productivity by keeping contact pressures applied on the package within + or -15% of the maximum from one end to the other of the package. CONSTITUTION:With a guide 9 supported by an elastic body 8a of relatively small coefficient of elasticity on both upper and lower surfaces, an adjustment screw 13 is adjusted so that a horizontal position of the winding start is obtained when a half contact pressure is applied on the tip of a drive roll 5. The coefficient of elasticity of the elastic body 8a is chosen to be smaller by 5% to 15% than the contact pressure at the foremost end set in the horizontal position with a deflection equivalent to the maximum inclination angle alpha of the drive roll 5. While the contact pressures the thread packages 11 and 12 receive during winding varies from 0% to 15% at the bottom and from 0% to -15% at the top, variation of these magnitudes are not detrimental to the physical property and form of the thread packages. These facts further contribute to improve physical property, uniformity and yield of the thread, unwinding speed of the thread packages and productivity.

Filed: 1991-05-16
Abstract: PURPOSE:To project the picture one the same screen on the side of the reception by synthesizing the video conference picture with other picture information and transmitting it and to improve the high definition of the screen. CONSTITUTION:A NTSC picture signal 13 is inputted in a NTSC picture signal processing circuit 17 and EDTV processing is performed for the signal. The output of the NTSC picture signal processing circuit 17 is inputted in one end of a picture synthetic circuit 21. Further, a high definition picture signal 15 is inputted in a high definition picture signal processing circuit 19 and the processing corresponding to the high definition screen is performed. The output of the high definition picture signal processing circuit 19 is inputted in the other end of the picture synthetic circuit 21. The output of the picture synthetic circuit 21 is inputted in a picture signal compression processing circuit 29 and is compressed. As this is the signal made by synthesizing two pictures and is a high definition picture signal, the information amount is expanded. Therefore, the information amount for one screen is reduced by compressing the signal to transmit this picture signal and is inputted in a picture signal transmission processing circuit 33.
