Title: Semiconductor device
Inventor: FUKADA SHINICHI
IPC: H01L21/314
Filed: 1987-05-25
Abstract: PURPOSE:To avoid misoperation by a method wherein a layer insulating film is composed of a sandwich structure of an insulating layer, an oxide superconducting material layer and an insulating layer. CONSTITUTION:After a 1st layer polycrystalline Si wiring 4 is formed, an insulating layer 10 made of Si3N4 and phosphorus silicate glass is formed. Then a Ba2YCu3O7-x thin film is formed by a sputtering method and subjected to a heat treatment to form a superconducting material thin film 11. Further, an insulating layer 14 made of phosphorus silicate glass is formed and a photoresist film 12 is formed on it. Then, O<+> ions are implanted only into a hole 15 which has a larger diameter than a contact hole 16 by photolithography to convert a part of the superconducting material film 11 into an insulating film 17. When a 2nd layer wiring is formed, patterning is carried out again by photolithography and, after the contact hole 16 is formed by dry etching, the 2nd layer Al wiring 9 is formed. With this constitution, the influences of the currents applied to the wirings can be cut off by the superconducting thin film 11 and misoperation and noise induced in the semiconductor elements of the upper and lower layers by the wirings can be suppressed.

Abstract: PURPOSE:To prevent the partial wear of friction plates by putting rotatably a rotary hub on the outer perimeter circle of an eccentric hub and at the same time, furnishing interveniently at the rotary hub a disk between the plane of an armature and the plane of a side plate through the friction plates. CONSTITUTION:As the drive of a shaft 2 is released and an electro magnetic coil 4 is demagnetized, an armature 8 is separated from the suction surface 3b of a field core 3 by the spring force of a brake spring 16, and a disk 13 is moved and friction plates 14, 15 on its both sides are press-welded. And the turning movement of the disk 13 is braked, and a rotary hub 11 stops and also, the shaft 2 stops. On the occasion of these stoppages, the disk 13 stops as it slides with both surfaces being rubbed with friction plates 14, 15, but stops as it keeps on making a planetary movement during the rotation before the stoppage of the shaft 2 as well as an eccentric hub 6 which is integral therewith.

IPC: G01R15/24
Filed: 1994-06-09
Abstract: PURPOSE:To provide a superior optical current transformer capable of correcting the variation of a light quantity due to the vibration and executing the current measurement with high accuracy. CONSTITUTION:A measurement light from a first laser diode 1 is subjected to the linear polarization by a polarizer 2. A second laser diode 11 emits a random polarization light of which wavelength is different from that of the measurement light. The measurement light and reference light are coupled with each other by a beam-coupling device 12 to be allowed to fall on a Faraday element 3. A light getting a Faraday optical rotation at the Faraday element 3 is divided into two polarization components by an analyzer 5, then each is divided into the measurement light and reference light by a two- wavelength divider 14 to be converted to respective electric signals by a photodiode 6. Each of the electric signals of the measurement light and reference light is sequentially operated by an amplifier 16, a subtracter 8, an AGC amplifier 7 and an electronic circuit 17, thereby obtaining a measurement current value in which the variation of the optical quantity due to the vibration is roughly corrected.
