  • Patent number: 9440533
    Abstract: A control apparatus for a vehicular 4-wheel drive system provided with: primary drive wheels to which a drive force is transmitted from a drive power source; auxiliary drive wheels to which the drive force is selectively transmitted; a first clutch configured to selectively place a first power transmitting path in a power transmitting state and a power cutoff state; and a second clutch disposed in a second power transmitting path to selectively place the second power transmitting path in a power transmitting state and a power cutoff state. The first and second clutches are placed in fully released states to establish a 2-wheel drive mode. The control apparatus includes a first-clutch control portion configured to bring the first clutch into a partially engaged state when a predetermined condition in which the vehicular 4-wheel drive system generates or is considered to generate a noise is satisfied in the 2-wheel drive mode.

  • Publication number: 20160229316
    Abstract: A shoulder support adjuster includes a shoulder support, a bending angle adjusting mechanism, and a bending position adjusting mechanism. The bending angle adjusting mechanism and the bending position adjusting mechanism are provided within the shoulder support of a vehicle seat. At the bending angle adjusting mechanism, a bending angle of the seatback is adjusted by inflating an airbag. Further, at the bending position adjusting mechanism, by inflating the airbag and airbags, a flexed position of a shoulder plate is moved downward, and a bending position of the seatback changes downward. The bending position of the seatback is thereby adjusted.

  • Patent number: 9413256
    Abstract: An object is to suppress deterioration of a high-voltage side battery regardless of the magnitude of a load current. Provided is a control device of a DC-DC converter that is constituted by a primary side circuit that is electrically connected between an input side and a transformer, and a secondary side circuit that is electrically connected between an output side and the transformer. The control device includes a command generating unit 325 that sets an output current limiting value to a predetermined value on the basis of a detected input voltage, a duty generating unit 330 that calculates a duty configured to turn ON/OFF a switching element on the basis of the output current limiting value and a detected output current, and a switching signal generating unit 335 that generates a switching signal on the basis of the duty. The duty generating unit 330 generates the duty so that an output current is limited to the output current limiting value or less.

  • Patent number: 8786565
    Abstract: A cellular phone 1 includes displays 11 and 12, touch sensors 12 and 22 which receives an operation on the displays 11 and 12, an external speaker 308 which performs a notification action, and a CPU 100 which controls the displays 11, 12 and the external speaker 308. Here, the CPU 100 displays a snooze button B6 and a dismiss button B7, which are a target of the operation, on the display 11 or 21 during the notification action. If an operation on the snooze button B6 is a confirmation flick, the CPU 100 stops the notification action and furthermore resumes the notification action if standby time elapses after the notification action stops. In contrast, if an operation on the dismiss button B7 is a confirmation flick, the CPU 100 stops the notification action and furthermore cancels a setting of the notification action.
