  • Patent number: 12221064
    Abstract: A key system for an automobile according to the present disclosure includes an on-vehicle device configured to transmit and receive a radio signal to and from an electronic key, and a resin panel through which the on-vehicle device is fixed to and held by a body of the automobile. The on-vehicle device includes a transmitter configured to transmit a search signal to the electronic key, a receiver configured to receive a response signal transmitted from the electronic key in response to the search signal, a control unit configured to control the transmission of the search signal, and a resin case. The smart key system for the automobile according to the present disclosure removes electrostatic charging generated by the search signal transmitted from the transmitter in either or both of the resin case and the resin panel.

  • Publication number: 20190190186
    Abstract: A connector structure may include a case and a connector. The case may include a case body accommodating an electronic substrate arranged therein and a cover structured to close an opening of the case body. The connector may include a terminal part supporting a plurality of terminals and a housing including a tubular part surrounding a plurality of tip end sides of the plurality of terminals. The terminal part may be structured as a separate component from the housing. The terminal part may be fixed on the electronic substrate. The housing may be integrally coupled to the cover. The terminal part and the housing may respectively include a plurality of positioning parts positioning the terminal part and the housing relative to each other.

  • Patent number: 8986018
    Abstract: There is provided a rotary connector device in which a flat cable is wound and accommodated in an annular space between a rotating rotor and a fixed stator. The rotor is provided with a rotor main body made of a PBT resin, and a rotor cover portion made of a polyacetal resin and overlapping the rotor main body to ensure strength of the rotary connector device and reduce sliding noises between the flat cable and the rotor. The rotor cover portion is provided with an opening portion for pulling the flat cable in the annular space out of the rotor main body, and a concave portion is formed in a disc portion of the rotor cover portion for improving work efficiency at the time of assembling the rotor main body and the rotor cover portion.

  • Patent number: 8740626
    Abstract: A spacer arranged in an annular space between a rotor and a stator for supporting a roller reversing a winding direction of a flat cable is made of plastic having high lubricating properties. First guide portions on an annular plate portion are spaced by equal intervals from each other. The first guide portion includes an inner guide rib having a semicircle cross section projecting inward, an outer guide rib having a semicircle cross section projecting outward, and a tension wall connecting the inner guide rib and the outer guide rib. A second guide portion is provided between the first guide portions, and includes three parallel plate ribs extending from an inner peripheral side to an outer peripheral side of the annular plate portion, and circumferential connecting walls connecting the three parallel plate ribs.

  • Patent number: 7407258
    Abstract: In an ink jet recording apparatus, it is detected whether or not an ejection has been performed at least one time while printing an image, with respect to each nozzle, within a predetermined period (preliminary on-paper ejection cycle corresponding to the checking area C1), and the nozzle which has performed the ejection at least one time is excluded from a target of preliminary ejection within a second predetermined period (preliminary on-paper ejection cycle corresponding to the checking area C2) subsequent to the above predetermined period. As for the nozzle not excluded from the preliminary ejection target, the preliminary ejection is performed at least one time onto paper (preliminary on-paper ejection area R2) as to each nozzle at a predetermined timing within the second predetermined period (preliminary on-paper ejection cycle corresponding to the checking area C2). Accordingly, printing is not interrupted by a head recovery processing, and also unnecessary preliminary ejection can be reduced.

  • Patent number: 7193166
    Abstract: A joystic device allows a knob to perform parallel movement, turning and depressing operations by a single operation of the knob. The device is provided with a knob formed of a non-turning portion in a center, and an operating portion provided to the non-turning portion so as to be relatively turnable such that a parallel movement operation and a depressing operation of the non-turning portion and the operating portion, and a turning operation of the operating portion are performed with respect to a case, and a parallel operating portion that supports the knob to allow the parallel movement and depressing operations of the non-turning portion and the operating portion, and the turning operation of the operating portion while receiving a turning regulation with respect to the case. In response to the operations of the parallel movement, turning, and depressing through the non-turning portion and the operating portion, corresponding one of detecting portions is operated.
