Publication number: 20010009724Abstract: Deposition of metal in a preferred shape, including coatings on parts, or stand-alone materials, and subsequent heat treatment to provide improved mechanical properties. In particular, the method gives products with relatively high yield strength. The products often have relatively high elastic modulus, and are thermally stable, maintaining the high yield strength at temperatures considerably above 25° C. This technique involves depositing a material in the presence of a selected additive, and then subjecting the deposited material to a moderate heat treatment. This moderate heat treatment differs from other commonly employed “stress relief” heat treatments in using lower temperatures and/or shorter times, preferably just enough to reorganize the material to the new, desired form. Coating and heat treating a spring-shaped substrate provides a resilient, conductive contact useful for electronic applications.Type: ApplicationFiled: January 29, 2001Publication date: July 26, 2001Inventors: Jimmy Kuo-Wei Chen, Benjamin N. Eldridge, Thomas H. Dozier, Junjye J. Yeh, Gayle J. Herman

Patent number: 6183618Abstract: A process for treating an impregnated electrolytic capacitor anode whereby the anode body is immersed in a liquid electrolytic solution and a voltage is applied to the anode body, whereby a current flows through and repairs flaw sites in the anode body. The liquid electrolytic solution includes an organic solvent comprising at least one of polyethylene glycol, polyethylene glycol monomethyl ether, and polyethylene glycol dimethyl ether. Alternatively, the electrolytic solution includes an organic solvent and an alkali metal phosphate salt. Preferably, the electrolytic solution contains both an alkali metal phosphate salt and an organic solvent comprising at least one of polyethylene glycol, polyethylene glycol monomethyl ether, and polyethylene glycol dimethyl ether.Type: GrantFiled: February 2, 1999Date of Patent: February 6, 2001Assignee: Kemet Electronics CorporationInventors: Brian J. Melody, John T. Kinard, David A. Wheeler

Patent number: 6176995Abstract: The current density with which the process is used is of essential importance for the economy of a method of electrolytically treating materials. Normally only low or medium current densities are used, as the speed of replacement of consumed materials in the direct vicinity of the surface of the material for treatment has a restrictive effect on the magnitude of the current density at which a usable process result can still be achieved. However, a low current density leads to long electrolysis times and to complex treatment installations.Type: GrantFiled: July 1, 1996Date of Patent: January 23, 2001Assignee: Atotech Deutschland GmbHInventor: Reinhard Schneider

Patent number: 5976342Abstract: A method for manufacturing an orifice plate that is built up in multiple layers and includes a complete axial through passage for a fluid. The orifice plate includes inlet openings, outlet openings, and at least one conduit lying between them. The layers or functional planes of the orifice plate are built up on one another by electroplating metal deposition (multilayer electroplating). Orifice plates manufactured in this manner are particularly suitable for use on injection valves in fuel injection systems, in paint nozzles, inhalers, or inkjet printers, or in freeze-drying processes, for spraying or injecting fluids such as beverages.Type: GrantFiled: March 3, 1998Date of Patent: November 2, 1999Assignee: Robert Bosch GmbHInventors: Stefan Arndt, Dietmar Hahn, Heinz Fuchs, Gottfried Flik, Guenter Dantes, Gilbert Moersch, Detlef Nowak, Joerg Heyse, Beate Ader, Frank Schatz

Patent number: 5865977Abstract: A process for electrochemical treating flow channels of metal workpieces uses a tool extending into the workpieces and an electrolyte flow between the tool and the flow channel. Either volume flow of the electrolyte, or pressure of the electrolyte, or both, are measured in a reference sample workpiece calibrated previously with test oil under high pressure and the determined electrolyte value is stored as a nominal value and used for a subsequent series treatment of the workpieces. This value is used as a regulating variable for termination of the treatment. The pressure of the electrolyte during the electrochemical series treatment of the workpieces is maintained at about 100 bars.Type: GrantFiled: June 30, 1997Date of Patent: February 2, 1999Inventor: Fritz-Herbert Frembgen

Patent number: 5700363Abstract: A porous nickel electrode substrate having a central high conductivity core sandwiched between two layers of porous conductive material such as nickel foam or nickel felt. The porous conductive material is plated with nickel and then sintered. By selectively controlling the plating of nickel on the porous material, variable conductivities may be designed into the substrate.Type: GrantFiled: February 15, 1996Date of Patent: December 23, 1997Assignee: Inco LimitedInventors: Victor Alexander Ettel, John Ambrose, Kirt Kenneth Cushnie, James Alexander E.
