  • Patent number: 11171319
    Abstract: The present invention relates to an electrolytic copper foil for a secondary battery, and a method of producing the same. The electrolytic copper foil for a secondary battery exhibits a little change in a physical property caused by a difference in a crosshead speed when tensile strength and an elongation percentage of the electrolytic copper foil are measured, thereby achieving excellent charging and discharging characteristics of a battery and preventing exfoliation of an active material. The electrolytic copper foil for a secondary battery is produced from a plating solution containing Total Organic Carbon (TOC), cobalt, and iron by using a drum, in which a ratio of the TOC to the cobalt and the iron contained in the electrolytic copper foil follows Formula 1 below. TOC/(cobalt+iron)=1.3 to 1.

    Abstract: An exemplary method of manufacturing a metal cover (1) with blind holes (3) therein includes: step (60), preparing a metal substrate; step (62), covering the metal substrate with a protective film formed by electrophoretic deposition; step (64), forming holes in the protective film according to an intended pattern of the blind holes in the metal cover, thus exposing the metal surface through the holes; step (66), etching the metal substrate in the exposed areas to form the blind holes; and step (68), removing a remainder of the protective film from the metal substrate, thereby obtaining the finished metal cover. The method involving etching is relatively low-cost. Additionally, because electrophoretic deposition is used to cover the metal substrate with the protective film, the protective film can be formed on all surfaces of the metal substrate. Thus the method is especially advantageous for manufacturing a metal cover having a three-dimensional shape.

  • Patent number: 6588095
    Abstract: A method, and structure formed thereof, for processing an exposed conductive connection between an thermal inkjet head device and a flexible tape circuit connectable to control signals for driving the inkjet device. According to the method of processing, the exposed conductive connection is electrophoretically plated with a polymer to protect it against corrosive damage by coupling the exposed conductive connection to a first voltage potential and immersing it into an electrophoretic polymer solution in contact with an electrode at a second voltage potential thereby establishing a current between the electrode and the exposed connection such that the exposed connection is coated with a thin film of polymer of uniform thickness.

  • Patent number: 6537435
    Abstract: 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 can 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.

  • Patent number: 6524457
    Abstract: 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.
