  • Publication number: 20220181910
    Abstract: A power receiving device includes: a power receiving antenna to wirelessly receive AC power from a power transmitting antenna in the power transmitting device; a power receiving circuit to convert the AC power received by the power receiving antenna into DC power and to output the DC power; an impedance adjustment circuit disposed on a transmission path between a load that utilizes the DC power and the power receiving antenna, the impedance adjustment circuit being capable of causing a change in input impedance thereof; and a power reception control circuit to control the impedance adjustment circuit. The power reception control circuit consecutively changes a value of the input impedance of the impedance adjustment circuit to a value selected from among a plurality of values, determines from among the plurality of values a value at which power to be supplied to the load becomes largest, and sets and maintains the input impedance at an operating impedance value that is based on the determined value.

  • Patent number: 11307515
    Abstract: A developing device includes a developer bearer, a developer regulator, a developer supply passage, and a stopper. The developer bearer includes a magnetic field generator and is configured to bear a developer containing toner and magnetic carriers and conveys the developer to a developing area by rotation. A stopper prevents the developer blocked by the developer regulator from moving to a surface of the developer bearer, while securing a supply path for passing the developer in the developer supply passage to the developer bearer between the stopper and an upper end of a side wall of the developer supply passage that is opposite to the developing bearer. A width of the supply path in a direction perpendicular to a direction of a rotation axis of the developer bearer is in a range of 7%-10% of a circumference of an outer diameter of the developing bearer.

  • Patent number: 11169431
    Abstract: The camera side mount is brought, by relative rotation with the accessory side mount, from a first state where each accessory side bayonet claw is inserted between the camera side bayonet claws into a second state where the camera side and accessory side bayonet claws engage with each other. The leaf spring biasing the camera side contact pins in the protruding direction is disposed between the camera side mount and the camera body. When the camera being in the normal position is viewed from the direction facing the camera side mount, the leaf spring extends from both sides of the mount center line, which extends from the center of the camera side mount in the direction of gravity, toward the camera side contact pins. The camera side contact pins are arranged at positions other than a position on the mount center line.
