Patent number: 7229537Abstract: A composite oxygen ion transport element that has a layered structure formed by a dense layer to transport oxygen ions and electrons and a porous support layer to provide mechanical support. The dense layer can be formed of a mixture of a mixed conductor, an ionic conductor, and a metal. The porous support layer can be fabricated from an oxide dispersion strengthened metal, a metal-reinforced intermetallic alloy, a boron-doped Mo5Si3-based intermetallic alloy or combinations thereof. The support layer can be provided with a network of non-interconnected pores and each of said pores communicates between opposite surfaces of said support layer. Such a support layer can be advantageously employed to reduce diffusion resistance in any type of element, including those using a different material makeup than that outlined above.Type: GrantFiled: June 10, 2004Date of Patent: June 12, 2007Assignees: Praxair Technology, Inc., BP Corporation North America, Inc.Inventors: Jack C. Chen, Charles J. Besecker, Hancun Chen, Earil T. Robinson

Patent number: 7229538Abstract: A microfluidic device has a plurality of H-shaped micro channels not connected to each other and formed on a substrate. Each of the H-shaped micro channels comprises two main channels separately placed on two opposite sides in parallel and a plurality of sub-channels perpendicularly connected to the two main channels. The present invention is designed in such a way that various reagents dropped into different H-shaped micro channels are immobilized on respective sub-channels because of the different widths of the main channel and sub-channel. Afterwards the reagents are coated with a layer of polymer. The polymer has a porous structure that allows the passage of any sample to be tested. Finally, a plurality of upper channels parallel to one another are directly fabricated in the polymer, or in another layer of polymer stacked on the previous polymer.Type: GrantFiled: September 11, 2003Date of Patent: June 12, 2007Inventors: Fan-Gang Tseng, Kuang-Hua Lin, Hui-Ting Hsu

Patent number: 7229540Abstract: To provide a biochip, a biochip manufacturing method, an electrophoresis method, and an electrophoresis apparatus, by which the detection accuracy may improve, there is a biochip introducing a sample in band form into a sample separation passage, by a means for reducing the band width of sample, at which the sample is before being introduced in the sample separation passage in band form. The band of sample supplied to the sample separation passage is compressed, and the expansion by diffusion may be prevented, thus the detection accuracy may improve.Type: GrantFiled: January 7, 2003Date of Patent: June 12, 2007Assignees: President of Shizuoka University, a Japanese Government Agency, ASTI CorporationInventors: Naomichi Okamoto, Noriyuki Okumiya, Ryo Sugimura

Patent number: 7229541Abstract: A processing solution tank of forming an agitating flow by flowing and circulating a processing solution in directions opposite to each other between the side of a liquid surface and the side of a tank bottom, in which a guide plate substantially of an arcuate shape is formed to an end of the tank situated at least to the downstream on the side of the liquid surface or the downstream on the side of the tank bottom in the agitating flow for reversing the flow downward to the tank bottom or upward to the liquid surface, and a swirl chamber having a swirl generating portion of a substantially arcuate face for capturing dusts is provided at the bottom of the tank, whereby high quality surface treatment, for example, electrodeposition coating can be conducted by uniformly stirring the processing solution so as not to cause backflow or turbulence in the processing solution tank while dipping a work on a conveyor in the processing solution.Type: GrantFiled: July 23, 2004Date of Patent: June 12, 2007Assignee: Trinity Industrial CorporationInventors: Hideaki Hara, Toshinori Watanabe

Patent number: 7229542Abstract: Molded structures, methods of and apparatus for producing the molded structures are provided. At least a portion of the surface features for the molds are formed from multilayer electrochemically fabricated structures (e.g. fabricated by the EFAB™ formation process), and typically contain features having resolutions within the 1 to 100 ?m range. The layered structure is combined with other mold components, as necessary, and a molding material is injected into the mold and hardened. The layered structure is removed (e.g. by etching) along with any other mold components to yield the molded article. In some embodiments portions of the layered structure remain in the molded article and in other embodiments an additional molding material is added after a partial or complete removal of the layered structure.Type: GrantFiled: May 7, 2003Date of Patent: June 12, 2007Assignee: Microfabrica Inc.Inventor: Christopher A. Bang

Patent number: 7229543Abstract: A method for measuring a target constituent of an electroplating solution using an electroanalytical technique is set forth in which the electroplating solution includes one or more constituents whose by-products skew an initial electrical response to an energy input of the electroanalytical technique. The method comprises a first step in which an electroanalytical measurement cycle of the target constituent is initiated by providing an energy input to a pair of electrodes disposed in the electroplating solution. The energy input to the pair of electrodes is provided for at least a predetermined time period corresponding to a time period in which the electroanalytical measurement cycle reaches a steady-state condition. In a subsequent step, an electroanalytical measurement of the energy output of the electroanalytical technique is taken after the electroanalytical measurement cycle has reached the steady-state condition.Type: GrantFiled: February 26, 2003Date of Patent: June 12, 2007Assignee: Semitool, Inc.Inventors: Lyndon W.
