Title: Production of carbon composite material
Inventor: OKUYAMA YASUO
IPC: C04B35/52
Filed: 1988-03-18
Abstract: PURPOSE:To obtain a high-density carbon composite material, by adding a mixed solution of two boiling point ranges prepared by fractional distillation to an aggregate, heat-treating to give the aggregate to which the pitchy substance is stuck, molding the aggregate into a sheetlike state, removing a light component, laminating, then molding and carbonizing. CONSTITUTION:A mixed solution of fractions which are obtained from coal-based or petroleum-based tar by fractional distillation and comprise a fraction having 200-550 deg.C boiling point and a fraction having >=500 deg.C boiling point in the blending ratio of preferably 10:3 is prepared. Then the mixed solution is added to an aggregate, which is heat-treated while stirring so as to uniformly disperse the aggregate. For example, carbon fibers, metallic fibers, inorganic compound fibers, etc. may be cited as the aggregate to be used. Then the heat-treated blend is cooled to a temperature wherein a necessary amount of the pitchy substance is stuck to the aggregate and the aggregate is separated from the mixed solution of the distilled components of the tar. The aggregate is molded into a sheetlike substance, which is then heat-treated in an inert atmosphere, infusibilized by distilling a light component, molded into a shape of final product, carbonized and calcined to give the aimed carbon composite material.

IPC: H02M3/135
Filed: 1988-03-23
Abstract: PURPOSE:To prevent the breakdown of a thyristor, by constituting a snubber circuit through connecting a diode in series with a parallel circuit of a capacitor and a resistance. CONSTITUTION:A snubber circuit for a GTO thyristor is constituted by further connection of a diode DS in series with a circuit by parallel connection of a capacitor CS2 and a resistance RS3. Then, when the GTO is turned OFF, electric current flowing through the GTO so far flows through a by-pass circuit of DS CS2 to control the rise of a GTO anode voltage. Also, when the thyristor connected in antiparallel with the GTO is turned ON, the forward voltage of thyristor(reverse voltage of GTO) is blocked by the diode DS so that the capacitor CS2 is not charged with electricity. Further, when a reactor is inserted into a short circuit, it is possible to control the rise of a discharge current of said snubber capacitor.
