  • Patent number: 11971682
    Abstract: A cartridge includes a first unit including a photosensitive member, and a second unit including a developer bearing member and a force receiving portion, the second unit being configured to be rotatable about a first axis to move with respect to the first unit between a first position and a second position. In a state where the first unit is in a same posture as when an image forming operation is performed, the second unit is disposed at the second position by its own weight. The developer bearing member is configured to be rotatable about a second axis. When seen in the direction of the first axis, a first distance between the force receiving portion and the second axis is smaller than a second distance between the first axis and the second axis and a third distance between the first axis and the force receiving portion.

  • Patent number: 11939641
    Abstract: A grain oriented electrical steel sheet includes the texture aligned with Goss orientation. In the grain oriented electrical steel sheet, when (?1 ?1 ?1) and (?2 ?2 ?2) represent deviation angles of crystal orientations measured at two measurement points which are adjacent on the sheet surface and which have an interval of 1 mm, the boundary condition BA is defined as [(?2??1)2+(?2??1)2+(?2??1)2]1/2?0.5°, and the boundary condition BB is defined as [(?2??1)2+(?2??1)2+(?2??1)2]1/2?2.0°, the boundary which satisfies the boundary condition BA and which does not satisfy the boundary condition BB is included.

  • Patent number: 5295920
    Abstract: An automatic transmission system having a belt type infinitely variable gear is housed in a transmission casing. The transmission casing is formed of a torque convertor housing portion in which the torque convertor is housed and an infinitely variable gear housing portion in which the infinitely variable gear is housed. A forward-reverse switching mechanism is provided between the torque convertor and the primary shaft of the infinitely variable gear and is supported on the torque convertor housing portion. Opposite ends of the primary shaft of the infinitely variable gear are supported on support portions respectively formed on the infinitely variable gear housing portion and the torque convertor housing portion, and opposite ends of the secondary shaft of the infinitely variable gear are supported on support portions respectively formed on the infinitely variable gear housing portion and the torque convertor housing portion.
