  • Patent number: 7619501
    Abstract: A rotary variable resistor including a rotator having at an upper part a disk-shaped flange provided with a rectangular first adjustment hole penetrating a circumferential portion thereof and at a lower part a cylindrical shaft, and an adjustment plate having a slider at a lower surface thereof and a second adjustment hole with a narrower width than that of the first adjustment hole on an annular flat plate portion. The rotator is integrated into the adjustment plate by fitting the adjustment plate into the shaft of the rotator with adjusting the position of the first adjustment hole with the second adjustment hole. Thus, a rotary variable resistor is configured. After a product is completed, by applying a force from the side of the first adjustment hole to a side wall in the direction of rotation of the second adjustment hole, the adjustment plate can be moved so as to adjust the output voltage ratio.

  • Patent number: 7507919
    Abstract: A multi-directional input device includes an operating shaft capable of rotating around a central axis thereof and tilting in multiple directions from the central axis; a rotating body rotating together with the operating shaft to sequentially connect or disconnect a slide contact and a fixed contact; and a plurality of horizontal push switches operable by tilting the operating shaft. The engaging surface between the operating shaft and the rotating body forms a curved surface having both arc element and noncircular element. The operating shaft and the rotating body are always in contact with each other in a large area. Thus, in both tilting and rotating operation, even an extended period of use causes less abrasion.

  • Publication number: 20070105456
    Abstract: A press-fit fixing terminal is mountable to a wiring board by being inserted into a through-hole of the wiring board, and includes a flat plate section and a resilient contacting section. The flat plate section is made of metal thin plate and double-backed such that an end of the flat plate section is placed on a root side and a bent point works as an insertion tip when the terminal is inserted into the through-hole. The resilient contacting sections sandwich the double-backed portion of the flat plate section such that they are placed symmetrically with respect to the double-backed portion and both of the ridges of the resilient contacting section face outward viewed from the double-backed portion, so that each one of the resilient contacting sections forms a V-shape including an obtuse angle.

  • Patent number: 7077656
    Abstract: A rotating electronic part has a board; a case composed of insulating resin; a supporting projection made of resin integrally structured with the case; and a rotating member. The board is provided with a central hole and three or more notches around the central hole at even angular intervals. The case fixes the board so as to maintain a penetration state of the central hole on the board. Each of the supporting projections is partially provided in one of the notches and projects to an inner radius of the central hole. The rotating member has a shaft inserted in the central hole on the board and is rotatably supported at the distal ends of the supporting projections; and a contact that faces to the board, makes a rotational movement with the rotation of the shaft, and contacts the board to output electric signals outward.

  • Patent number: 6975249
    Abstract: Rotary electronic component of the invention has a contact board and an elastic contact. The contact board, including an annular contact having an arc-segmental portion split by a slit with a predetermined width and signaling contacts disposed at spaced positions and in electrical continuation with the arc-segmental portion, is fixed in a resin molding with the annular contact exposed on the top plane of the resin molding. The elastic contact slides on the contact board along the annular contact. In this rotary electronic component, a stress occurring when the annular contact is fixed by molding on to the contact board is relaxed owing to presence of the slit. Thus, a rotary electronic component generating an electric signal with a stabilized waveform over a long time can be obtained.
