Title: Heat-resistant composite material having high thermal conductivity and production thereof
Inventor: HORIGUCHI AKIHIRO
IPC: C04B35/581
Filed: 1987-05-08
Abstract: PURPOSE:To obtain the titled composite material having improved heat- resistance, strength and thermal conductivity, by using Al nitride as a principal phase and an Ni-Al intermetallic compound as a subsidiary phase and restricting contents of Ni and impurity oxygen within specific ranges. CONSTITUTION:A molded article is produced by mixing Al nitride powder having an impurity oxygen content of <=7wt.% and an average particle diameter of 0.05-5mum with <=20wt.% of an Ni compound in terms of Ni element. As an alternative method, a sintered article having an Ni content of <=20wt.%, containing AlN as a principal phase and containing (Ni-Al-O) compound and/or (Ni-O) compound phase is prepared beforehand. The article is calcined by heating at 1,650-2,050 deg.C in N2 gas atmosphere for >=3hr. A composite material containing AlN as a principal phase and an Ni-Al intermetallic compound as a subsidiary phase can be produced by this process. Since the Ni content and impurity oxygen content are restricted to <=20wt.% and <=8,000ppm, respectively, the obtained composite material has improved heat-resistance and thermal conductivity.

Title: Electric double-layer capacitor
Inventor: KURABAYASHI KEN
IPC: H01G11/34
Filed: 1990-04-30
Abstract: PURPOSE:To increase capacitance without scaling up size by using activated carbon treated at a low temperature as a polarizable electrode and employing an alkaline electrolyte as an electrolyte. CONSTITUTION:An activated-carbon powder sintered body is used as a solid polarizable electrode. The adsorption of an acidic electrolyte and an alkaline electrolyte differs by an activation temperature or a heat treatment temperature after activation in activated carbon, and activated carbon activated at a low temperature or thermally treated excellently adsorbs the alkaline electrolyte. Consequently, the alkaline electrolyte such as KOH is employed and weight mol concentration is set within a specified range, thus acquiring an electric double layer capacitor, capacitance of which is increased by twice or more though internal resistance is made slightly larger than a case when an H2SO4 electrolyte is used. Accordingly, capacitance can be augmented without scaling up size.
