Patent number: 5779775Abstract: The object of the present invention is to provide a stock solution composition for use in production of hard polyurethane foam, which composition can disperse the flame retardant filler component stably therein when allowed to stand and, when subjected to stirring or an external pressure, has a reduced viscosity, promising easy transfer of the composition and easy foaming in production of hard polyurethane foam at the site. The present invention provides a stock solution composition for use in production of hard polyurethane foam, which comprises, as the essential components, a polyol, a foaming agent, a flame retardant filler, a flame retarder and a solvent-swollen clay mineral. The swollen clay mineral has thixotropy; that is, it is a gel owing to the interaction between molecules when allowed to stand and, when subjected to an external pressure or the like, said interaction between molecules is cut and the gel changes into a liquid sol.Type: GrantFiled: April 8, 1997Date of Patent: July 14, 1998Assignee: Nisshinbo Industries, Inc.Inventors: Shin Kuwabara, Kazuhisa Nagata, Yasuo Imashiro, Eiji Sasaki

Patent number: 5270259Abstract: A silicone resin is applied on a substrate to form a coating film. The coating film is subjected to a reactive ion etching in an atmosphere containing at least O.sub.2. Thus, the film is inorganized in its surface and has a distribution of the residue, an organic radical, contained therein gradually increasing in the depth thereof. This permits an insulating film having excellent heat endurance to be formed without generation of any cracks. This insulating film is very useful as an interlayer insulating film for multi-layer wiring.Type: GrantFiled: March 11, 1991Date of Patent: December 14, 1993Assignees: Hitachi, Ltd., Hitachi VLSI Engineering CorporationInventors: Shinichi Ito, Yoshio Homma, Eiji Sasaki, Natsuki Yokoyama

Patent number: 4770720Abstract: Grooves are formed on a finish-annealed electrical steel sheet by applying a mean load of from 90 to 220 kg/mm.sup.2 to the steel sheet, which is then heat treated at a temperature of 750.degree. C. or higher, and thereby fine crystal grains are generated at the strain-introduced sites of the steel sheet. The fine crystal grain reduces the watt-loss value. Such a watt-loss improving effect is not impaired even by stress-relief annealing.Type: GrantFiled: September 5, 1986Date of Patent: September 13, 1988Assignee: Nippon Steel CorporationInventors: Hisashi Kobayashi, Eiji Sasaki, Katsuo Eto, Takeo Nishimura
