  • Patent number: 11362667
    Abstract: A device includes a master delay-lock loop (DLL) having a phase frequency detector connected in series with a charge pump that is to generate a control voltage. A slave DLL is coupled to the master DLL and has a delay line including a buffer to receive a slave clock and a series of delay cells coupled between the buffer and an output terminal that is to output a delay clock, the series of delay cells variably controlled by the control voltage. The master DLL and the slave DLL are powered by a power supply that experiences undershoot or overshoot in response to a load transient. A dummy load is coupled between the delay line of the slave DLL and an output of the power supply, the dummy load including an exclusive OR gate that receives, as inputs, a first output of the buffer and the delay clock.

  • Publication number: 20220042580
    Abstract: A gear reducer has a helical gear, an eccentric shaft that is joined to the helical gear and has a first supporting portion that is offset in a rotation radial direction with respect to a rotation shaft of the helical gear, and a slider plate that is disposed at a radial direction outer side of the eccentric shaft. Further, the gear reducer has a transmitting gear that is supported at a first supporting portion, and whose rotation around its own axis is restricted due to the transmitting gear being engaged with the slider plate, and that revolves due to the helical gear rotating together with the eccentric shaft, and has an output gear body that rotates due to the transmitting gear revolving. The transmitting gear has a pair of restricting projections that project-out toward the slider plate side, and the slider plate is disposed between the pair of restricting projections.

  • Patent number: 11047433
    Abstract: This clutch includes an annular clutch housing, a rotationally driven drive-side rotating body, a driven-side rotating body, a rolling body, and a support member. The clutch is configured such that, when the drive-side rotating body starts to rotate when driven, the drive-side rotating body comes into contact with the support member in a rotational direction and presses the rolling body in the rotational direction through the support member, thereby releasing the rolling body from gripping effected by the clutch housing and the driven-side rotating body. The support member includes a load generation section for generating a load which makes it difficult for the support member to rotate about the rotation axis of the drive-side rotating body when at least the drive-side rotating body starts to rotate when driven.

  • Patent number: 11002322
    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.
