  • Patent number: 9073571
    Abstract: A lower spoke cored bar of a spoke cored bar constituting a spoke portion couples one end portion of a first coupling portion to a rim cored bar. The lower spoke cored bar couples one end portion of a second coupling portion to a boss cored bar. The lower spoke cored bar is provided with a vertical wall portion which couples a bending-shaped first bent portion to the other end portion of the first coupling portion, and which couples a second bent portion in a bending form to the other end portion of the second coupling portion. The rim cored bar is provided with a deformation allowing portion capable of deforming. The vertical wall portion and deformation allowing portions are arranged substantially on the same line.

  • Patent number: 9027955
    Abstract: First support portions 71 and 72 positioned on a predetermined straight line L2 approximately perpendicular to a broken line of a hinge portion is set in a support portion 70 that supports a back plate 27 with respect to a back face side of a door portion 36. Second and third support portions 73 and 74 positioned in line symmetry with respect to the straight line L2, are set in the support portion 70. It is possible to receive the centrifugal force, which is applied to the back plate 27 due to the expansion of the door portion 36, with good balance by the first to third support portions 71, 72, 73, and 74. An emblem 24 can be reliably fixed to the door portion 36 with preventing a fixing pin 31 from being excessively locked into a through hole 33 more than necessary.

  • Publication number: 20120283901
    Abstract: There is provided a control system for a hybrid vehicle. When it is detected that an ignition power supply line has been cut off (that an ignition switch has been switched OFF) during EV travel realized by disengaging a transmission clutch, a self-shut function is stopped while keeping a switching transistor of a self-shut line ON, and the transmission clutch is maintained in a disengaged condition by keeping a transmission clutch actuator energized.

  • Publication number: 20110258422
    Abstract: There is a need to provide a microcomputer capable of eliminating an external terminal for endian selection. Flash memory includes a user boot area for storing a program executed in user boot mode and corresponding endian information and a user area for storing a program executed in user mode and corresponding endian information. A data transfer circuit reads endian information stored in the user boot area or the user area in accordance with operation mode and supplies the endian information to a CPU before reset release of the CPU. Accordingly, an external terminal for endian selection can be eliminated.

  • Patent number: 7483593
    Abstract: When a line number counted by a line number counting unit corresponds to a prescribed line number, a transfer source address generating unit adds an offset address set in an offset address setting unit to respective transfer source addresses to output as addresses to a memory. A DMA control unit controls DMA transfer in accordance with a transfer source address generated by the transfer source address generating unit and a transfer destination address generated by a transfer destination address generating unit. Thus, rapid enlargement/reduction of image data becomes possible.

  • Patent number: 7095191
    Abstract: A control apparatus of an electric vehicle in which relays are switched to a disconnecting state without causing failure of the electric vehicle. Main relays Ry1, Ry2 switchable between a connecting state and a disconnecting state are provided between a drive motor 11 for driving driven wheels and a motor drive battery 34 for supplying current to the drive motor 11. When these main relays Ry1, Ry2 are to be switched to the disconnecting state, it is determined whether or not the output current I from the motor drive battery 34 is below a predetermined current and whether or not the vehicle speed V is below a predetermined speed. When it is determined that the output current I is below the predetermined current and the vehicle speed V is below the predetermined speed, the main relays Ry1, Ry2 are switched to their disconnecting states.

  • Publication number: 20010052648
    Abstract: A silicide layer in direct contact with a gate electrode layer of a MOS transistor is formed only in a contact hole reaching the gate electrode layer, and is located only in the bottom portion of the contact hole. Thereby, increase in gate interconnection resistance is prevented, and thereby decrease in drive power of the transistor can be prevented.
