  • Patent number: 9877396
    Abstract: A method for producing a receptacle for a sensor element, such as a combustion chamber pressure sensor, includes introducing a first amount of a pre-ceramic substance into an injection mold, forming a base layer of the receptacle by molding the pre-ceramic substance in the mold, and applying at least one conductor track to the base layer. A further amount of a pre-ceramic substance is introduced into the mold onto at least a partial region of the conductor track. A top region of the receptacle is formed directly on the base layer while at least partially covering over the conductor track by molding the further pre-ceramic substance in the injection mold.

The heating element includes a conductive core which is surrounded by an insulator layer, which in turn supports a resistive layer. An optional conductive jacket can surround the resistive layer. These layered components are pre-formed in prior operations and then assembled one into the other to form a precursor structure. The precursor structure is transferred to a die, where it is compressed to form a so-called green part having dimensional attributes proportional to the finished heating element. The individual layers remain substantially intact, with some boundary layer mixing possible to enhance material-to-material bonding. The green part is sintered to bond to various materials together into an essentially solid mass. Various finishing operations may be required, following which the heating element is assembled to form a glow plug.

  • Patent number: 7165316
    Abstract: An electrical resistor is made by providing a sacrificial layer and conductive pads disposed on a first surface of the sacrificial layer. An electrically resistive material is deposited over the pads and on the first surface of the sacrificial layer to form at least one unit including the resistive material and the pads. At least part of the sacrificial layer is then removed so as to expose one or more of the pads.

  • Patent number: 7069642
    Abstract: A method of fabricating a current control device is presented. The method impregnates a pressure conduction composite within a current control device with a fluid additive via suffusion. The suffusion process is performed by placing the pressure conduction composite within a bath of a liquid additive. The method generally includes the steps of mixing a compressible non-conductive matrix and conductive filler, forming a pressure conduction composite composed of the non-conductive matrix having the conductive filler electrically isolated therein, suffusing the composite within a bath so as to impregnate the composite with an additive, and attaching a pair of conductive plates to the composite. Alternate methods include attaching non-conductive plates to the composite, forming pores within the pressure conduction composite, and inserting a temperature responsive material into a porous composite.

  • Patent number: 7069641
    Abstract: The present invention discloses a method for preparing a conductive polymeric composite material having carbon black utilized to a structure for composite materials of a positive temperature coefficient thermistor. The method first provides a metal laminated material comprising a top metal layer and a bottom metal layer, an insulating layer between the top and the bottom metal layer, and a conducting through hole disposed between the top metal layer and the bottom metal layer. A composite electroplating process is then performed to form an composite electroplating layer on the surface of the top metal layer, wherein the composite electroplating layer is a continuous porous structure with a secondary aggregation of carbon black and electroplated metal.

  • Patent number: 6900610
    Abstract: The invention is a system for controlling the position of a movable member moved by a prime mover by monitoring the position of the movable member; generating position information based upon this monitoring; and controlling the prime mover based upon the position information by providing a counter force to the movable member substantially equal to an opposing force opposing the movement of the movable member. The invention may include a movable member, such as a ram used for fastening a terminal to a wire; a spring; a DC planetary gear motor for providing a force to the movable member opposing the spring; a position detector, such as an linear voltage displacement transducer, to detect the position of the movable member and generate position information; and a controller, which may include a logic board or microprocessor and memory, for controlling the force from the motor in response to the position information.
