Patent JP-H0374880-A (JP)
Title: Semiconductor device
Inventor: UEMOTO YASUHIRO
IPC: H01L29/78
Filed: 1989-08-16
Abstract: PURPOSE:To obtain a device with a high withstand voltage characteristic without providing an offset part by providing a plurality of thin-film FETs within an Si layer on an insulation substrate and connecting a source and a drain commonly and mutually. CONSTITUTION:An SiO2 12 and poly Si 21 are laminated on an Si substrate 11. Then, an SiO2 13 and a P-doped poly Si 14 are superposed, etching is made using a resist mask, and then a gate oxide film 13 and a gate electrode 14 are formed. Then, a P ion is implanted with the gate as a mask for annealing, thus forming a source 15 and drains 16-1 to 5. A device is formed, where a plurality of thin-film FETs where the source and the drain are connected commonly are connected in series. With this configuration, when a gate voltage VG is constant and a high drain voltage VD (5) is applied to the drain 16-5 of this serial FET, operation proceeds in inversely biased state in sequence from the drain side so that a large drain voltage is not concentrated on only the FET which is closest to the drain 16-5 and is distributed uniformly to each FET at a smaller value below the withstand voltage, thus greatly improving withstand voltage between the source 15 and the drain 16-5.

Title: Insulating apparatus of arrester
Inventor: NAKAYAMA TETSUYA
IPC: H01T4/10
Filed: 1990-08-08
Abstract: PURPOSE:To prevent flashing over owing to inner overvoltage and make it possible to send electricity owing to restarting a breaker by a method wherein a driving apparatus is operated when an a. c. trouble earthing current runs in an arrester to drive either one of discharging electrodes in electricity applied side or earthing side and enlarge the discharging gap in air. CONSTITUTION:When shutting a continuous current succeeding the lightning surge current becomes impossible owing to extraordinarily large lightning surge current, waves are filtered by a filter circuit F by the a.c. continuous current and in the case that the current is equal to or larger than a prescribed level, an electric power source apparatus E is started by a level determining circuit L, so that a driving apparatus S is started. Owing to the start of the driving apparatus, a stopper 21 rotates and is released from a stopping part 20. Next, a discharging electrode 14 rotates contraclockwise owing to an accelerating force of a rotary spring 19 and the discharging gap G in air is enlarged and becomes the minimum insulating gap. In this way, insulating gap is retained and flashing over against the assumed opening and shutting surge and short-time overvoltage is not caused, so that a breaker in a substation becomes possible to be re-started and sending electricity can be resumed.
