Patent number: 7204410Abstract: A structure of a system using an IC card is simplified. A controller and active antennas are connected to each other through a bus. The controller transmits a command outputted from a host computer and including an ID for discriminating the active antennas to all the active antennas connected to the bus. The respective active antennas judge whether or not the received command is directed to itself by checking the contained ID. In the case where it is judged that the command is directed to itself, transfer of data to the IC card is performed, and the result is transferred to the controller through the active antenna and the bus.Type: GrantFiled: May 20, 2005Date of Patent: April 17, 2007Assignee: Sony CorporationInventors: Yuji Murayama, Susumu Kusakabe, Katsuyuki Tanaka

Patent number: 7076833Abstract: An automobile door checker includes a check plate, a shoe holder housed in a case, a shoe that is held by the shoe holder and the shoe slides on the check plate accompanying relative movement between the case and the check plate, and a check spring that resiliently urges the shoe holder toward the check plate in order to press the shoe against the check plate. The shoe is axially supported in the shoe holder so that the shoe can swing from a neutral position to forward and backward swing limits. The shoe is provided with return-to-neutral means for exhibiting a return force that makes the shoe return to the neutral position. The contact area between the shoe and the check plate is arranged so that the frictional force in the contact area becomes the smallest when the shoe reaches the shoe swing limits.Type: GrantFiled: April 14, 2004Date of Patent: July 18, 2006Assignees: Rikenkaki Kogyo Kabushiki Kaisha, Honda Motor Co., Ltd.Inventors: Yuji Murayama, Junichi Yoshioka
