  • Publication number: 20080098819
    Abstract: A pressure sensor, which is to be used in an environment involving vibrations, includes a case and a sensor chip. The case has an inner surface that is to be disposed perpendicular to a direction of the vibrations. The sensor chip is to sense a pressure in the environment and generate a sensing signal representative of the sensed pressure. The sensor chip has a pressure-receiving surface and is secured in the case with the pressure-receiving surface perpendicular to the inner surface of the case. With such an arrangement, since the pressure-receiving surface of the sensor chip is accordingly to be parallel to the direction of the vibrations, the influence of the vibrations on the pressure-receiving surface can be minimized. Consequently, high accuracy of the pressure sensor can be ensured.

  • Publication number: 20070212234
    Abstract: Provide a suction muffler capable of enhancing the reliability of compressor, by preventing production of molten resin (slag) which solidifies in the suction muffler. Fit or put in contact with each other bonding portion (140) of a plurality of resin members (105), (120) formed in advance by injection molding, and bond bonding portion (140) with a resin belt formed with secondary injection molding. Because the bonding is made with the heat of the molten resin itself, it becomes possible to provide a suction muffler capable (101) of enhancing the reliability of compressor, by preventing production of slag due to pressing of bonding portion (140).

  • Patent number: 7030360
    Abstract: A photoreceptor is provided with an erroneous operation detection circuit for monitoring an output signal supplied from a slew rate variable output stage. The erroneous operation detection circuit performs such controls that a slew rate of output is decreased within a range in which a transmission speed of the slew rate variable output stage is not decreased. With this arrangement, it is possible to inhibit adverse effect on the output signal due to a parasite current caused between an output terminal of the photoreceptor and photoelectric converting means, such as a photodiode.

  • Publication number: 20040173425
    Abstract: A collapsible upright wall extends the height of the sides on the load hauling box on a truck. The collapsible upright wall comprises a fabric which when vertically stretched provides adequate resistance to substantial lateral load. A method of increasing the volumetric capacity of the box on a truck comprises the steps of: a) providing a rectangular frame above, and dimensioned to seat adjacent to an open top side portion of the load hauling box on the truck; b) providing a substantial lift mechanism to uniformly lift the rectangular frame above the box; and, c) providing and attaching an elongate strip of fabric having a top elongate side portion peripherally attached to the rectangular frame, and a bottom elongate side portion peripherally attached to the open top side portion of the box. Then when the rectangular frame is lifted to an upper operable position the fabric is stretched taut and is thereby able to sustain significant lateral load.

  • Patent number: 6786490
    Abstract: A metal gasket for a high performance of an engine includes two sheets of elastic metal substrates providing a bead on peripheral portion of a cylinder opening and an annular thin metal plate that is thinner than the elastic metal substrates and surrounds the cylinder opening and is arranged between the substrates. The annular thin metal plate is fixed on the substrate by inserting an engaging portion solidly projected from the outside periphery into a slit formed on the substrate and folding the plate. Due to the thin metal plate, the cylinder opening peripheral portion has a high seal contact pressure in contrast to other locations. Moreover, the contact pressure of the cylinder opening peripheral portion becomes uniform.
