  • Patent number: 10883553
    Abstract: Provided is a one-way clutch in which a rotating direction of a first rotating member with respect to a second rotating member is switched. The first rotating member includes a recessed portion that receives a planetary gear and, in an outer circumferential portion thereof, an engaging portion that engages with the planetary gear, whereby relative rotation of the planetary gear and the first and second rotating members is switched to rotatable and unrotatable. When the first rotating member is relatively rotating with respect to the second rotating member, the planetary gear meshes with an internal gear of the second rotating member, and the position of the planetary gear is thereby restricted.

  • Patent number: 10727771
    Abstract: In order to shorten an activation time while realizing stable motor control, a motor control apparatus operable to control a motor is provided. The apparatus controls so as to drive the motor by the forced commutation control in a duration from a start of control of the motor until a first time period elapses, and control so as to drive the motor by the vector control after the first time period has elapsed. In addition, the apparatus controls an execution frequency of a current detection and a rotation speed estimation. The apparatus controls so that a first execution frequency in a second time period after a switch is made from driving by the forced commutation control to driving by the vector control is greater than a second execution frequency in a third time period subsequent to the second time period.

  • Publication number: 20200165090
    Abstract: A conveyance apparatus includes a change conveyance unit. In a case where a first sheet in a sheet storage unit included in the feeding apparatus is fed in a landscape orientation to the conveyance apparatus, the change conveyance unit changes a conveyance orientation of the first sheet to a portrait orientation. The landscape orientation is an orientation in which a short side of the first sheet is parallel to a sheet conveyance direction of the first sheet. The portrait orientation is an orientation in which a long side of the first sheet is parallel to the sheet conveyance direction. The change conveyance unit changes the conveyance orientation of the first sheet from the landscape orientation to the portrait orientation on a substantially horizontal region between the image forming apparatus and the feeding apparatus.

  • Publication number: 20200101928
    Abstract: An airbag includes a mounting portion, a top wall deployable towards a vehicle occupant, and a circumferential wall disposed between the mounting portion and top wall. An airbag base member for forming the airbag includes a top-forming panel for forming the top wall, and at least three circumferential panels that extend generally radially from the top-forming panel and form the circumferential wall by being joined together by adjoining edges thereof. Each of the circumferential panels is formed into a generally band-like contour which has a first and a second curving edges that make the circumferential panel enlarge in width from the leading end towards an intermediate portion and then narrow towards the top-forming panel. When the airbag base member is laid flat, adjoining edges of any two adjoining circumferential panels are generally symmetrical to each other in curving shape with respect to a line disposed there between.
