  • Patent number: 6173487
    Abstract: A fan speed controller of an automotive vehicle air conditioning device is usually placed in an air flow duct to be effectively cooled. Thus, compact construction of the speed controller is needed to obtain a larger air flow in the air flow duct. For this purpose, various compact resistor units for the speed controller have been proposed. However, some of them are poor in durability against shocks. In view of this, a compact resistor unit for a speed controller includes a resistor block that has a flat resistor, a flat insulating plate and a flat radiation plate which are respectively positioned against one another. The compact resistor unit further includes a holder block of molded plastic on which the resistor block is mounted. The compact resistor unit also includes a plurality of metal terminals partially embedded in the holder block, where the terminals are connected to particular portions of the flat resistor.

  • Patent number: 4068206
    Abstract: Disclosed is a pressure-sensing transducer in which a transducing unit comprising a semiconductor-type strain element is confined within a housing defining a generally funnel-shaped chamber. The unit is supported within the housing in spaced relationship with the surface of the chamber by an electrically non-conductive cup-shaped member of relatively rigid material, and a resilient electrically non-conductive ring which is yieldably deformed by sealing engagement of outer peripheral surface portions of the ring with the chamber and the inner cup surface of the member, and the inner periphery of the ring with the outer circular surface of the unit. A viscous flow-resistant, electrically non-conductive liquid occupies any open space in the chamber for communicating pressure from a pressure source through the small end of the chamber to the element within the unit.
