IPC: H03K17/732
Filed: 1986-04-30
Abstract: PURPOSE:To protect a gate circuit by connecting a diode having a large current capacity in anti-parallel with a transistor (TR). CONSTITUTION:When a signal is inputted to a TR 3, an on-gate current is conducted through a resistor 5, a GTO 8 is turned on, and when a signal is inputted to a thyristor 7, an off-gate current is conducted through an inductance 6, the GTO 8 is turned off.

Title: Silicon carbide member and its production
Inventor: ICHIJIMA MASAHIKO
IPC: C04B41/89
Filed: 1990-04-13
Abstract: PURPOSE:To prevent attack on silicon in a base material of silicon carbide and to carry out purification to the inner part by forming a glassy carbon layer on the surface of a base material composed of silicon impregnated silicon carbide. CONSTITUTION:A porous molded body of silicon carbide is obtained by molding a pelletized matter prepared by the known method, e.g. by adding phenolic resin to a purified silicon carbide powder and kneading the resulting mixture, applying heating to the resulting molded body to cure the resin, and exerting calcination. Silicon is impregnated into the above molded body by the known method to form a base material of silicon impregnated silicon carbide, and then, this base material is coated with glassy carbon by means of immersion in glassy carbon and/or application of glassy carbon by the known method. The glassy carbon has stable stability as well as chemical stability at high temp., and further, it does not react with purification treatment gas, etc., in the case, e.g. of application to the surface of the base material of silicon impregnated silicon carbide because it is minimal in pores, and, as a result, it can protect the base material. Moreover, since impurities can be passed through the glassy carbon with great facility, purification can sufficiently reach the base material even if the base material surface is uniformly coated with the glassy carbon by means of application, etc.
