  • Patent number: 11161710
    Abstract: A sheet separation device to open a two-ply sheet includes a rotator; a nipping member disposed opposite the rotator and configured to nip the two-ply sheet with the rotator; a conveyor configured to convey the two-ply sheet between the rotator and the nipping member, and a winding member disposed adjacent to the rotator. The conveyor conveys the two-ply sheet with a bonded portion of the two-ply sheet being an upstream end or a downstream end of the two-ply sheet in a conveyance direction of the two-ply sheet. The winding member winds the two-ply sheet around the rotator, to create a difference in winding circumferential length between the two sheets and separate the two sheets.

  • Publication number: 20210302343
    Abstract: This invention prevents measurement error from becoming large in thermoelectric conversion coefficient evaluation and enhances evaluation efficiency. This invention is a physical property evaluation device for evaluating the physical properties of a plurality of solid materials formed on a substrate. The physical property evaluation device comprises an electromotive force measurement means that forms closed circuits including the individual solid materials and measures the electromotive forces occurring at the two ends of each of the solid materials, a means for producing heat flow within the individual solid materials, an external magnetic field generation means for generating a uniform magnetic field having a given intensity and direction in the vicinity of the individual solid materials, and an automation means for evaluating the physical properties of the individual solid materials using the electromotive force measurement means, heat flow production means, and external magnetic field generation means.

  • Patent number: 7584995
    Abstract: An actuatable knee bolster provided in an instrument panel of a vehicle to protect lower legs of an occupant seated in a front seat of the vehicle. The actuatable knee bolster includes: an opposing section opposed to the lower legs of the occupant; a driving section driving the opposing section to move toward and away from the occupant; and a shock absorbing section configured to be plastically deformed when making contact with the lower legs of the occupant. In the actuatable knee bolster, the driving section is disposed inside the shock absorbing section.

  • Patent number: 5094212
    Abstract: A throttle body assembly for supplying a mixture of fuel and air to an intake port of an internal combustion engine, integrally incorporating a fuel injection valve, a fuel pump, a fuel supply passage defined in the throttle body and extending from the fuel pump to the fuel injection valve, and a fuel pressure control valve directly incorporated in the throttle body to control pressure of fuel in the fuel supply passage. Thus, there is no need to use an external tubing system for supplying and returning fuel to and from the fuel injection valve, and the throttle body assemby may be simplified in structure so as to facilitate the assembling and servicing of the throttle body assembly. Further, an electronic control unit and sensors associated with the control unit are both directly mounted on the throttle body so that wiring around the throttle body may be eliminated.
