  • Publication number: 20150133282
    Abstract: Provided is a sheet folding device comprising a deceleration means which halts a sheet by pressing. A pressure member such as rubber is disposed upon the leading end of a rod-shaped member which is rotatably retained. A sheet is decelerated by the pressure member being applied obliquely to the sheet. The entire surface of the rubber does not make close contact with paper, and thus, a wrinkle is not formed in the paper. It is possible to ensure a stable folding location.

  • Patent number: 8567818
    Abstract: A vibration damping structure for a steering wheel includes an airbag mounted in the steering wheel, an inflator arranged forward of the airbag, and a support member elastically supporting the inflator at a position forward of the inflator. The inflator includes a peripheral wall portion and gas ports formed in the wall portion. The support member has a hole facing the inflator. A sealing portion is provided to surround the hole. Through contact between the inflator and the support member at the sealing portion, gas leakage via the hole is prevented. The inflator has a pressure receiving portion in the vicinity of the gas ports to change the flow direction of gas, which is discharged outward from the gas ports in the radial direction of the wall portion, to a direction toward a rear side. The pressure receiving portion produces force acting forward by receiving pressure from the gas.

  • Patent number: 8547313
    Abstract: A driving apparatus includes a voltage applying unit, a light irradiation unit and a resistance control unit. The voltage applying unit forms a voltage applying circuit together with a pair of electrode layers of a photo-addressing type display element. The voltage applying unit applies a voltage between the pair of electrode layers. The light irradiation unit irradiates the photo-addressing type display element with addressing light. The resistance control unit controls a resistance to a current which flows in a direction to reduce a potential difference between the pair of electrode layers to be larger than that during a period in which the voltage applying unit is applying the voltage.
