Patent number: 8052858Abstract: A resin material is brought into contact with a first solution containing ozone, and at the same time, ultraviolet rays are irradiated. The activation due to the treatment with ozone water and the activation due to the treatment with ultraviolet rays are synergistically operated to enable the formation of a plated coating having excellent adhesive strength by a short treatment. In addition, even by a long treatment, the adhesive strength can be restrained from lowering. Consequently, a plated coating having excellent adhesion can be formed without roughening the surface of the resin material by a short pretreatment.Type: GrantFiled: October 9, 2003Date of Patent: November 8, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Motoki Hiraoka, Takeshi Bessho, Sigeru Sibata

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: 7964069Abstract: A device for galvanic coating of a piston has a pot-shaped interior for accommodating the piston and an electrolyte fluid, a holder device for fixing the piston in place, a cover that is structured like a shutter and leaves only the surfaces of the piston that are to be coated uncovered, a first electrical contact that is connected with an anode and with the plus pole of a direct voltage source, and a second electrical contact that connects the piston with the minus pole of a direct voltage source. The piston can be simply and quickly attached to the holder device, since the holder device is in plate shape, and has an oblong centering device, the length of which corresponds to the radial inside diameter of the piston to be coated so that the piston can be pushed onto the centering device by way of its underside.Type: GrantFiled: August 30, 2007Date of Patent: June 21, 2011Assignee: MAHLE International GmbHInventors: Rudolf Bergmann, Kurt Nikolei
