  • Stator and motor
    Patent number: 11916454
    Abstract: A stator includes a stator core that includes a core back portion having an annular shape and with a central axis as a center and tooth portions extending from the core back portion to an inside in a radial direction and arranged in a circumferential direction, insulators that are attached to the tooth portions from the inside in the radial direction, a coil that is wound around the insulator, and a cover that supports an inner surface of the insulator opposing the inside in the radial direction from the inside in the radial direction.
    Type: Grant

  • Electrode wire for wire electric discharge machining
    Patent number: 7868265
    Abstract: An electrode wire for wire electric discharge machining includes a binary alloy of copper and zinc. The electrode wire is manufactured by hot-extruding an alloy including copper and zinc at a predetermined ratio and then cold-drawing and annealing the hot-extruded alloy, and ? phase crystals and ?? phase crystals uniformly exist.

  • Toner recycle control system of electrophotographing device using viscous liquid developing solution
    Patent number: 6687477
    Abstract: The present invention provides a toner recycling control system which stably feeds a liquid developer of an appropriate concentration to a liquid developing apparatus employing a high-viscosity liquid developer; appropriately adjusts the concentration of residual developer collected after development and after transfer; and feeds the adjusted developer to the developing apparatus. The toner recycling control system collects a post-development residual developer from a developer-bearing body and a post-transfer residual developer from an image-bearing body; performs developer concentration adjustment to yield an adjusted developer; and feeds the adjusted developer back to the developer-bearing body.
