Patent number: 7763113Abstract: The present invention provides a photocatalyst material, which can comprise a photocatalyst with an excellent adherence to a substrate and a high photocatalytic activity, and a production method thereof. The photocatalyst material (20) obtained by reacting crystal nuclei with a sol solution containing an organic metallic compound or the like and then carrying out gelation, solidification and heat treatment has a structure where more than one basic structures (10) are fixed to the surface of the substrate (1). The basic structure consists of abase portion (2) comprising crystal nuclei fixed to the surface of the substrate (1) and a photocatalyst crystalline body (3), which connects to and is extended from the base portion (2) and has a columnar structure having a hollow portion (5) formed therein. A cylindrical substrate may be used for the substrate (1). The above photocatalytic activity is further enhanced by the formation of an interior-exposing structure (8) in a shell portion (4).Type: GrantFiled: June 14, 2002Date of Patent: July 27, 2010Assignee: Andre Andes Electric Co., Ltd.Inventors: Azuma Ruike, Takeshi Kudo, Yuko Nakamura, Kazuhito Kudo, Fumie Kawanami, Akira Ikegami

Publication number: 20100141181Abstract: A highly heat resistant wire based on niobium or tantalum or niobium tantalum alloy for single-side socket lamps is enriched, according to the invention, with phosphorus and converted into an annealed state. The wire exhibits a yield strength Rp 0.2 of at least 200 MPa or a tensile strength Rm of at least 300 MPa. For the production of a frame for single-side socket lamps, a metal based on niobium or tantalum or an alloy thereof is doped with phosphorus and the doped metal is cold shaped into a wire, this wire is annealed and formed into a frame. This frame is used for the simultaneous current supply and holding of a burner in a single-side socket lamp.Type: ApplicationFiled: August 11, 2006Publication date: June 10, 2010Applicant: W.C.

Patent number: 7687007Abstract: Method for manufacturing a mold tool (1), devised for forming a structured nanoscale pattern on an object (24) and having a layer (16) which is anti-adhesive with regard to the object (24). A stamp blank (2) is provided with a structured pattern (4) on a surface (8). The patterned surface (8) is coated with a layer (6) of a metal, which has a stable oxidation number and can form a mechanically stable oxide film. The metal layer (6) is oxidized for forming of an oxide film (10). The oxide film (10) is exposed to a reagent comprising molecule chains (18), each of which has a linkage group (20) which bonds to the oxide film (10) by chemical bonding, wherein the molecule chains (18) either at the outset comprise at least a group (22) comprising fluorine, or in a subsequent step is provided with at least one such group (22).Type: GrantFiled: June 16, 2003Date of Patent: March 30, 2010Assignee: Obducat ABInventors: Torbjörn Ling, Lars Montelius, Matthias Keil, Marc Beck

Publication number: 20100032061Abstract: A method for manufacturing a Ni-based alloy article which elutes little Ni even when used in a high-temperature water environment for a long period comprises heating the Ni-based alloy in a carbon dioxide-containing atmosphere for a set period of time at an elevated temperature to form an oxide film comprising chromium oxide on a surface thereof. Using carbon dioxide as an oxidizing gas produces an oxide film of generally uniform thickness along a length of the article being treated so that resistance to nickel elution is more uniform over the entire article.Type: ApplicationFiled: August 10, 2009Publication date: February 11, 2010Inventors: Hiroyuki Anada, Shoji Kinomura, Noriaki Hirohata, Manabu Kanzaki, Kazuyuki Kitamura

Publication number: 20090322464Abstract: A method for manufacturing an electric contact material is provided which can prevent it from being adhesively melted even when being exposed to high temperatures resulting from an arc induced by an electric current being turned on or off. Also an electric contact material which is manufactured by the method and a thermal fuse are provided. A surface layer portion of an alloy containing 1 to 15 mass % of Cu, 0.01 to 0.7 mass % of Ni, and the remainder of Ag and unavoidable impurities is supplied with an amount of oxygen exceeding the amount of oxygen required for internal oxidation of Cu to form an oxygen concentrated layer. This alloy can serve as an electric contact material. This electric contact material is formed into a movable electrode, which is in turn employed for a thermal fuse.Type: ApplicationFiled: May 20, 2008Publication date: December 31, 2009Applicant: TANAKA KIKINZOKU KOGYO K.K.Inventors: Toshiya Yamamoto, Kazuyasu Takada, Kiyokazu Kojima

Patent number: 7604703Abstract: In a process of fabricating a stent composed primarily of niobium alloyed with a trace amount of zirconium, tantalum, or titanium for hardening, the stent is annealed under vacuum in a substantially oxygen-free environment. The vacuum is preferably maintained at pressure less than 10?4 millibars, oxygen-content less than about 80 parts per million, and the annealing temperature exceeds 400° C. for at least one hour, and is preferably kept in a range from about 1100-1200° C. for several hours. This may be followed by applying a surface layer of oxide, such as iridium oxide, with a thickness of 299-300 nm to the stent.Type: GrantFiled: May 3, 2006Date of Patent: October 20, 2009Assignee: Boston Scientific SciMed, Inc.Inventors: Torsten Scheuermann, Eckhard Alt
