The fluid control device is prepared from a film including at least an aluminum layer and an AlSi mixed film by forming an anodized alumina film having fine pores by way of an anodization process for the aluminum layer part and also forming a silicon based micro-porous film having very fine pores containing silicon as principal ingredient by way of an anodization process or etching process for the AlSi mixed film. The fluid control device can be used as filter or ultrafilter film that allows fluid and gas to pass through it.Type: GrantFiled: December 11, 2003Date of Patent: March 20, 2007Assignee: Canon Kabushiki KaishaInventors: Tohru Den, Kazuhiko Fukutani

Patent number: 7122107Abstract: A process is disclosed for stabilizing certain colored anodized coating on aluminum articles against degradation by ultraviolet radiation. Anodized articles colored by an electrolytic or interference process can thereafter be stabilized by heat treating them at temperatures of the order of 350° F. for a period of an hour or so. The process is particularly useful for use on electrolytically colored, anodized vehicular external body panels made from suitably formable sheet metal aluminum alloys.Type: GrantFiled: August 28, 2003Date of Patent: October 17, 2006Assignee: General Motors CorporationInventors: Sheila Farrokhalaee Kia, Hong-Hsiang Kuo, Yar-Ming Wang

Patent number: 7094327Abstract: The invention relates to a composition for treating magnesium alloys aimed at improving the resistance thereof to corrosion. The composition is an aqueous solution with a pH ranging between 7 and 10, containing a niobium salt, hydrofluoric acid, and optionally a zirconium salt, phosphoric acid, and boric acid. The alloy is treated in an electrochemical cell in which said alloy acts as an anode. The cell contains an inventive composition at a temperature between 20° C. and 40° C. as an electrolyte. An initial voltage which is sufficient to create a current density between 1.5 and 2.5 A/dm2 is applied to the cell, whereupon the voltage is progressively increased to a level ranging between 240 and 330 V in order to maintain the initial current density.Type: GrantFiled: January 31, 2003Date of Patent: August 22, 2006Assignee: Univeriste Pierre et Marie CurieInventors: Hélène Ardelean, Philippe Marcus

Patent number: 7070687Abstract: Apparatus and method for treating a surface of a substrate for electrolytic or electroless plating of metals in integrated circuit manufacturing. In one embodiment the method includes forming a barrier layer on a substrate. A metal-seed layer is then formed on the barrier layer. The method continues by performing in situ surface treatment of the metal-seed layer to form a passivation layer on the metal-seed layer. In another embodiment of a method of this invention, a substrate is provided into an electroplating tool chamber. The substrate has a barrier layer formed thereon, a metal seed layer formed on the barrier layer and a passivation layer formed over the metal seed layer. The method continues by annealing the substrate in forming gas to reduce the passivation layer. A conductive material is deposited on the substrate using an electrolytic plating or electroless plating process.Type: GrantFiled: August 14, 2001Date of Patent: July 4, 2006Assignee: Intel CorporationInventors: Vinay B.
