  • Patent number: 9381908
    Abstract: A hybrid vehicle control apparatus includes a first clutch disposed between an engine and a motor, and a second clutch disposed between the motor and a driving wheel. A lockup controller performs a lockup operation to shift the second clutch from slip state into completely engaged state when a predetermined lockup condition is satisfied under a condition that the second clutch is in the slip state. A second clutch transmitted torque capacity controller performs a lockup-condition second clutch control to control transmitted torque capacity of the second clutch to a value higher by a set quantity than an input torque to the second clutch while the lockup operation is being performed. The input torque corresponds to a state of depression of an accelerator pedal during the shifting of the second clutch from the slip state into the completely engaged state.

  • Patent number: 8465165
    Abstract: A method for producing a display member that can restrain lights from leaking from a remainder chip of a runner and a portion around the remainder chip. The method includes laminating a transparent layer on a light-diffusing layer; forming slant surfaces each having an slant angle of more than 45 degrees with respect to an extending direction D of a runner, the slant surfaces being provided around a portion on the rear surface of the transparent layer to which the runner is connected and being inclined cutting out the runner at a position along and near the slant surfaces; and forming a shielding layer on a remainder chip of the runner and on a rear surface of the display member main body inside the remainder chip by spraying a light-shielding material onto a front surface of the display member main body and a side part of the remainder chip.
