  • Patent number: 9719566
    Abstract: A one-way clutch includes a first rotational member, a second rotational member, and a first rotational body. The second rotational member has plural first through holes in which bolts are inserted. A dimension of the first through hole in a circumferential direction is larger than a dimension of the first through hole in a radial direction. A first region and a second region are obtained by dividing the first through hole into two regions in the circumferential direction. The first region is located ahead of the second region in a rotatable direction of the second rotational member. The bolts are inserted such that the each of the bolts is located in the first region of the first through hole, and the second rotational member and the first rotational body are fastened by the bolts.

  • Publication number: 20170182997
    Abstract: A control system for a hybrid vehicle configured to promptly shift a drive mode. In the single-motor mode, the vehicle is powered by a second motor while bringing an engagement device into disengagement and stopping the engine. In the dual-motor mode, the vehicle is powered by both a first motor and the second motor while bringing the engagement device into engagement and stopping a rotation of the output shaft of the engine by a stopper device. When shifting the drive mode from the single-motor mode to the dual-motor mode, the control system controls the first motor in a manner such that a speed difference between an input speed and an output speed of the engagement device is reduced while increasing a torque transmitting capacity of the engagement device.

  • Publication number: 20170159727
    Abstract: Since one end of a spring is received by a planar portion of a spring seat provided on any one of an outer plate and an inner plate, it is possible to support the spring with a planar member without machining a bottom wall face of the outer plate into a planar shape. Since the spring seat has seat guide portions that contact the outer plate, it is possible to suppress the fluctuation of the spring seat and the fluctuation of the spring by the seat guide portions, so it is possible to reliably prevent interference of the spring with its peripheral portion. Therefore, a load on the spring is reduced, so it is possible to improve the durability of a one-way clutch.

  • Publication number: 20170090951
    Abstract: A method may include associating, with a timer-B, a second application in a terminal device; setting the terminal device in a standby mode; and executing the second application when a processor in the terminal device wakes up after the timer-B measures a second amount of elapsed time. The timer-B may not initiate wake-up of the processor. The method may further include determining whether the second application is associated with the timer-B or a timer-A when the terminal device receives a command of setting the terminal device in the standby mode; and when the second application is determined as being associated with the timer-A, unassociating the second application with the timer-A. The timer-A may initiate wake-up of the processor when the timer-A measures another second amount of elapsed time while the terminal device is the standby mode. A timer associated with a first application may initiate wakeup of the processor.
