Patent number: 6841191Abstract: A fabricating method and apparatus of an zinc phosphate coating for a varistor has a insulation formed on a surface of a body which does not include two opposite ends of the body formed two outer terminals. The insulation has anti-etch feature for the electrolyte, so that the exposed surface of the body prevents to be etched and to be electroplated a metal material on it. Therefore the varistor has a great fabricating yield and the great shape after electroplating the two outer terminals step.Type: GrantFiled: February 8, 2002Date of Patent: January 11, 2005Assignee: Thinking Electronic Industrial Co., Ltd.Inventor: Chien-Liang Wu

Patent number: 6725514Abstract: A method of making a low-cost metal diaphragm sensor that integrates both pressure and temperature sensing in a single sensor assembly utilizes thick-film processing to form a circuit including stress and temperature sensitive elements on the outboard or exposed surface of a thin metal diaphragm separating the circuit from a pressurized fluid. Only a thin layer of dielectric separates the stress and temperature sensitive elements from the diaphragm surface. The stress sensitive elements respond to mechanical stressing of the diaphragm due to the presence of the pressurized fluid, while the temperature sensitive element responds to the temperature of the pressurized fluid. The thermal capacity of the fluid greatly exceeds that of the diaphragm, so that the temperature responsive characteristic of the temperature sensitive element accurately reflects the temperature of the pressurized fluid.Type: GrantFiled: May 31, 2002Date of Patent: April 27, 2004Assignee: Delphi Technologies, Inc.Inventors: James I.
