Patent number: 6524457Abstract: A photocatalytic oxidation purification system includes an ultra violet light source and a filter that comprises a pleated wire mesh substrate with a nanophase metal oxide oxidation catalyst suspended on the substrate, wherein the catalyst is applied without an adhesive using an electromechanical plating process. As a fluid containing organic contaminants is directed through the filter in the presence of ultra violet light from the light source, the catalyst oxidizes and decomposes the organic contaminants into environmentally harmless components. Methods of making the purification system including preparing a solution of catalyst and applying the catalyst without adhesive binding material to the filter substrate electromagnetically.Type: GrantFiled: July 7, 2000Date of Patent: February 25, 2003Inventor: Robin Scott

Publication number: 20030034249Abstract: An image forming method wherein an aqueous dispersion is prepared in a vessel of an apparatus. The aqueous dispersion contains an electrodeposition material including a fine particle coloring material, and a polymer which is chemically dissolved, or is deposited and precipitated, by a change in pH. The vessel is able to hold a liquid, and has therein an image supporting member. The image supporting member has at least an electrode, which can supply current or an electric field in accordance with an image pattern, and a surface which can support an image; and a counter electrode which forms a pair of electrodes together with the electrode. The electrodeposition material is deposited and precipitated to form an image by supplying current or an electric field in accordance with an image pattern to the image supporting member and the counter electrode and by changing the pH value of the aqueous dispersion in the vicinity of the image supporting surface of the image supporting member.Type: ApplicationFiled: January 12, 2001Publication date: February 20, 2003Applicant: Fuji Xerox Co., Ltd.Inventors: Eiichi Akutsu, Shigemi Ohtsu, Lyong Sun Pu
