  • Patent number: 8785777
    Abstract: An actuator control device includes a circuit device that is resin-molded by a plurality of metal molds including at least one movable metal mold to include a first bus bar and a second bus bar. The first bus bar and the second bus bar each include a flat plate-like portion that includes two main flat-face portions having large surface areas, and two sub flat-face portions that are adjacent to the main flat-face portions and have smaller surface areas than the surface areas of the main flat-face portions. One of the main flat-face portions of the first bus bar faces one of the main flat-face portions of the second bus bar. The facing direction differs from the mold release direction of the movable metal mold.

  • Publication number: 20120219330
    Abstract: A toner container and system for mounting and/or securing the toner container includes a toner container having a toner dispensing hole, a shutter, and a protrusion. The shutter is movable relative to the toner dispensing hole, and is to selectively close the toner dispensing hole. The protrusion is connected to the shutter and movement of the protrusion causes the shutter to move relative to the toner dispensing hole to cover the toner dispensing hole. There is a receiver including a movable catch, the movable catch being in a first position when the toner container is initially inserted into the receiver, and the movable catch moving to a second position upon insertion of the toner container into the receiver. The movable catch interacts with the protrusion of the toner container when the toner container is being removed from the receiver.

  • Publication number: 20120195645
    Abstract: A system with a container including a protrusion, and a receiver to receive the container. The receiver includes a slide block that is movable relative to a body of the receiver, the slide block including two surfaces, a first surface, initially contacted by the protrusion of the container during insertion of the container into the receiver, having a first slope to resist movement of the container towards the receiver, and a second surface, subsequently contacted by the protrusion of the container during the insertion of the container into the receiver, having a second slope to interact with the protrusion of the container to assist movement of the container towards the receiver. This construction provides the user with a changing insertion force to indicate proper mounting of the container.
