Patent number: 8039045Abstract: An object of the present invention is to provide a plating method on a glass base plate. The method allows forming a plating film on a base plate composed of a glass material with excellent adhesivity and homogeneity by means of an electroless plating method even to a thickness of 1 ?m or more. Before forming a plating film by a step of electroless plating S6, a surface treatment process is conducted on a surface of the base plate composed of a glass material. The surface treatment process comprises at least a step of glass activation treatment S2 to increase quantity of silanol groups on the surface of the base plate at least by a factor of two using an aqueous solution of diluted acid, a step of silane coupling agent treatment S3, a step of palladium catalyst treatment S4, and a step of palladium bonding treatment S5.Type: GrantFiled: July 27, 2005Date of Patent: October 18, 2011Assignee: Fuji Electric Co., Ltd.Inventors: Youichi Tei, Akira Iso, Kazuhito Higuchi, Hajime Kurihara, Hiroyuki Uwazumi

Patent number: 7913516Abstract: A crystalline glass with a characteristic of precipitating crystals from the surface of the crystalline glass to the interior thereof when it is being heated at a temperature higher than the softening point is used in the invention. A plurality of small crystalline glass masses 12 are accumulated and leveled in a fireproof mold coated with a mold release agent, and two crystalline glass plates 14A and 14B cut in an S shape are placed on the accumulated surface of the small crystalline glass masses 12 with the cut faces tightly bonded. A heat treatment is then performed to obtain a crystallized glass article having patterns. The crystalline glass plate can be cut into any shape to tightly bond the cut faces, and therefore the obtained crystallized glass articles have different patterns like natural-marble-like patterns, human figure patterns, animal patterns, etc. The invention also discloses a method of producing crystallized articles having patterns.Type: GrantFiled: September 21, 2009Date of Patent: March 29, 2011Assignee: Jian Quan Glass Development Company Ltd.Inventor: Kuo-Chuan Hsu
