  • Patent number: 11438536
    Abstract: An imaging device that includes pixels arranged in a matrix having rows and columns, the pixels including first pixels and second pixels different from the first pixels, the first pixels and the second pixels being located in one of the columns, each of the pixels including a photoelectric converter that converts incident light into signal charge, and a first transistor having a first gate, a first source and a first drain, the first gate being coupled to the photoelectric converter. The imaging device further includes a first line coupled to one of the first source and drain of the first pixels; a second line coupled to one of the first source and drain of the second pixels; a third line coupled to the other of the first source and drain of the first pixels; and voltage circuitry coupled to the third line and that supplies a first and second voltage.

  • Patent number: 11378175
    Abstract: An actuator includes an electric motor, an output shaft and a speed reducer. The speed reducer is configured to transmit rotation, which is outputted from the motor, to the output shaft after reducing a speed of the rotation outputted from the motor. The speed reducer includes an output gear joined to the output shaft and a compound gear. The compound gear includes a large diameter gear, which has a plurality of large gear teeth, and a small diameter gear, which has a plurality of small gear teeth. One of the large diameter gear and the small diameter gear is a metal gear, which is made of a metal member, while another one of the large diameter gear and the small diameter gear is a resin gear, which is made of a resin member, and the resin gear is integrally molded together with the metal gear in one piece.

  • Publication number: 20220015530
    Abstract: A toothbrush includes a head portion (10) having a bristle tufting surface; a grip portion (30) disposed on a rear end side from the head portion; a neck portion (20) disposed between the bristle tufting surface (11) and the grip portion; and a sensing portion (70) for sensing that an external force in a first direction orthogonal to the bristle tufting surface exceeds a threshold value. A reversal portion (80) connects a first region and a second region, and snaps, buckles, and reverses as the head portion is displaced on a rear surface side due to the external force exceeding the threshold value. An elastic deformation portion (90) connects the first region and the second region, and elastically deforms at least up to the external force at which the reversal portion snaps, buckles, and reverses.
