Title: Manufacture of compound semiconductor device
Inventor: OIKAWA RYUICHI
IPC: H01L21/338
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To manufacture a field effect transistor(FET), having an offset structure where only the source side is self-aligned through a less number of processes without using a gate electrode as a mask.

Title: Starting material composition for generating gaseous silicon monoxide
Inventor: AIBA YASUHIRO
IPC: C01B32/40
Filed: 1982-08-12
Abstract: PURPOSE:To obtain the titled composition capable of increasing the generation of gaseous SiO which can be used very effectively in the conversion of the surface of a graphitic material into SiC by mixing silica powder with carbon black in a specified ratio. CONSTITUTION:Silica powder is mixed with carbon black in 3.0-4.5 weight ratio of SiO2/C. Coke powder is used as a conventional carbon source. When coke powder is used, starting materials for generating gaseous SiO remain by >=40% after generation, resulting in low efficiency. The reason for the defect is considered to be in that gaseous SiO generated by the reaction of the surface of coke powder with silica reacts with the inside of the coke powder and forms SiC because the particle size of the coke powder is several 100mum. The defect can be eliminated by using carbon black of a very small particle size, and gaseous SiO can be generated efficiently.

IPC: H02P7/282
Filed: 1982-08-12
Abstract: PURPOSE:To reduce the capacity of a field controller by inserting a switch to a shunt circuit connected in series with a series circuit of an exciter and a field winding and opening the switch on full-field operation. CONSTITUTION:For operate the motor in a full-field manner, voltage generated from the exciter 3 is brought to 0, the switch 6 is opened, and an induction coil 4 is detached from the field winding 12.

Title: X-ray target base made of carbon
Inventor: IWAKI HIDEHIKO
IPC: H01J35/10
Filed: 1984-07-09
Abstract: PURPOSE:To increase the mechanical strength of an X-ray target base by stacking several pieces of nonwoven fabric formed by arranging carbon fibers in one direction. CONSTITUTION:After several prepregs are stacked each of which is formed either by impregnating carbon fibers arranged in one direction with a resin before it is hardened or by nonwoven fabric consisting of randomly arranged carbon fibers, the thus stacked prepregs are shaped into a given form. Next, the shaped stacked prepregs are bound together by a carbon matrix formed by resin impregnation, hardening, sintering and similar process, thereby making an X-ray target base. Alternatively, in order to increase the mechanical strength in the circumferential direction, fibers are wound in a disk-like form by a filament winding method and then thus formed fiber disks are bound together by a carbon matrix, thereby making an X-ray target base. An anticathode 3 is obtained by coating the thus made X-ray target with tungsten. Consequently, it is possible to increase the mechanical strength of the X-ray target base.

Abstract: PROBLEM TO BE SOLVED: To obtain a small switching power supply, in which an intelligent power device(IPD) for switching can be used, even when a power-supply input voltage is extremely low and which can moreover prevent overheating. SOLUTION: In this power supply, when an input DC voltage Vi is a voltage which is considerably lower than the ordinary usage range of an IPD 3 (an integrated switching device with a built-in control circuit), a control signal Sc is supplied to a control terminal TC of the IPD 3 from a control circuit 7, and the IPD 3 is pulled into an operational state. After that, when the IPD 3 is set to a steady-state operation, a current which is made to flow in the primary winding of a high-frequency transformer in an energy conversion part 4 is controlled intermittently by the IPD 3 according to a feedback signal Sf, and a desired output voltage Vo is extracted from the secondary winding of the transformer via an output rectifying part 5.  The control signal Sc which can operate the IPD is generated, on the basis of an output-side potential-state signal Sp from the power terminal TP of the IPD 3.

Title: Breakwater reducing pressure of high tidal waves by introduction hole
Inventor: MATSUMOTO YASUAKI
IPC: E02B3/06
Filed: 1986-06-18
Abstract: PURPOSE:To break waves as well as to reduce the pressure of tidal current acting on a level by a method in which, an opening is formed in the front face of a breakwater and a circular arc form of introduction hole is formed from the opening to the upper part of the breakwater. CONSTITUTION:An opening 2 is formed in the front face 1 of a breakwater, and an opening 4 is formed in the upper part of the breakwater.
