  • Patent number: 9086782
    Abstract: A display-controlling device includes: a display-controlling unit that controls a display unit to display an image indicating an item selected upon receipt of an instruction at a receiving unit, wherein if a first image indicating a first selected item is displayed at a first position, and an item instructed to be selected changes from the first selected item to a second selected item, the display-controlling unit causes there to be displayed, without erasure of the first image, a second image indicating the second selected item at a second position, which position is reached from the first position by movement in the first direction by an amount based on a position of the second selected item as viewed from the first selected item, with simultaneous movement in a second direction other than the first direction by a predetermined amount.

  • 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.
