Patent number: 7214881Abstract: An electrical connection is made by connecting a metal element to a second element to which the electrical connection is desired to be made by means of a conductive material disposed onto one or both of the metal element and the second element so as to contact and disperse about or through the metal element thereby providing both an electrical and a mechanical connection. The metal element may be a strip or pad with openings or knurls formed such as by stamping, a wire that is flattened and knurled, or a mesh material such as a wire mesh. In a preferred embodiment, the conductive material is a metal capable of withstanding harsh, high temperature environments, such as a noble metal. In another preferred embodiment, the second element is a ceramic element, preferably with a noble metal conductive pad thereon, to which the metal element is attached.Type: GrantFiled: August 25, 2004Date of Patent: May 8, 2007Assignee: Delphi Technologies, Inc.Inventors: Charles Scott Nelson, Robert G. Minard, Paul Hugo Ruterbusch, Kathryn Mary McCauley, Kaius Kiiren Polikarpus

Patent number: 7007653Abstract: A composition for forming an electrode for use in a torch jet spark plug is provided. The composition comprises a ceramic material, ceramic particles, and an electrically conductive material. The ceramic particles are dispersed within the ceramic material. At least some of the ceramic particles have a predetermined size. This predetermined size is at least as large as the thickness of the finally formed electrode. The electrically conductive material is capable of being manipulated to form ribbons around the ceramic particles and of being sintered to form the electrode. The resultant electrode has good resistance to explosive erosion mechanisms, which consequently increases the life of the torch jet spark plug.Type: GrantFiled: May 6, 2003Date of Patent: March 7, 2006Inventors: William J. Labarge, Kaius Kiiren Polikarpus, Keith Michael Brenske

Patent number: 6800158Abstract: A conductive co-fired body for an electrochemical cell for an exhaust sensor comprises zirconia, yttrium oxide, and alumina. The body comprises about 15 to about 30 weight % monoclinic phase zirconia. This produces an electrochemical cell having low impedance wherein the zirconia body and alumina body are co-fired. One method for manufacturing the electrochemical cell comprises combining zirconia, yttria, and alumina with solvent and dispersant to form a mixture. After, binder is added to the mixture which is then de-aired and cast onto a tape surface. The tape is dried, metallized, and laminated to an unfired alumina surface. The structure is then co-fired to form a body for said electrochemical cell.Type: GrantFiled: January 23, 2001Date of Patent: October 5, 2004Assignee: Delphi Technologies, Inc.Inventors: Kaius Kiiren Polikarpus, Walter Thomas Symons, Kerry J.

Patent number: 6572747Abstract: The method of making a wide range oxygen sensor of the present invention enables ease of handling and processing, particularly in a mass production environment. This process comprises forming planar composite elements of the sensor where the elements are individually laminated. These laminated composites are easily handled and readily stacked. Furthermore, electrodes and electrode leads can be readily deposited on the laminated composites, across the intersection of the various materials forming the composite. After deposition of the electrodes, leads, and a heater, the elements are stacked accordingly and laminated to produce the oxygen sensor.Type: GrantFiled: March 8, 1999Date of Patent: June 3, 2003Assignee: Delphi Technologies, Inc.Inventors: Richard Eugene Fouts, Lora B. Younkman, Raymond Leo Bloink, Kaius Kiiren Polikarpus

Patent number: 6562747Abstract: The electrolyte comprises up to about 80 wt % zirconia, up to about 30 wt % stabilizer, and up to about 40 wt % dopant-zirconia. Alternatively, the electrolyte can comprise zirconia having a phase chemistry, wherein the phase chemistry, at about 25° C., is about 15 wt % to about 35 wt % monoclinic, less than about 10 wt % tetragonal, balance cubic, based upon the weight of the zirconia in the electrolyte.Type: GrantFiled: December 19, 2000Date of Patent: May 13, 2003Assignee: Delphi Technologies, Inc.Inventors: Walter Thomas Symons, Kaius Kiiren Polikarpus, Kerry J.
