  • Publication number: 20190162248
    Abstract: A clutch includes a roller arranged between a clutch housing and a driven side rotating body. The roller is rotated about a rotation axis of a drive side rotating body together with the drive side rotating body when the drive side rotating body is rotationally driven. The roller hinders rotation of the driven side rotating body by being sandwiched between the clutch housing and the driven side rotating body when the drive side rotating body is not rotationally driven. The support member sandwiches the roller between the clutch housing and the driven side rotating body. The support member rotates about the rotation axis of the drive side rotating body together with the drive side rotating body. The grease is arranged between the clutch housing and the roller. The support member restricts rotation of the roller about a central axis of the roller.

  • Patent number: 10263654
    Abstract: A radio frequency signal can be received in an intermediate frequency mode suitable for radio wave reception conditions. An oscillator has a variable oscillation frequency. A quadrature demodulator includes a frequency mixer and generates an intermediate frequency signal having an intermediate frequency lower than the frequency of the radio frequency signal. An ADC receives the intermediate frequency signal passed through an analog filter and converts the received intermediate frequency signal to a digital signal. A channel selection signal processing section generates a demodulated signal from the intermediate frequency signal converted to the digital signal. A mode control section switches the operating mode of the quadrature demodulator between a zero intermediate frequency mode and a low intermediate frequency mode in accordance with the radio wave reception conditions.

  • Publication number: 20190093415
    Abstract: A clutch is configured, when a driving-side rotor is in a non-driven-rotated state, to prevent rotation of a driven-side rotor by setting a rolling element in a lock state in which the rolling element is held by a control surface and a collar. The clutch is configured so that when the driving-side rotor is driven and rotated in the lock state, the driving-side rotor pushes the rolling element via two circumferential holders in a rotation direction to release the rolling element from the lock state. Each of the two circumferential holders includes a guide portion configured to guide the rolling element toward a radially inner side of the collar when the rolling element is released from the lock state.
