  • Patent number: 9397527
    Abstract: A stator unit including a coil in which a distance between an m?1-th turn and an m-th turn is wider than each distance in a first turn to the m?1-th turn. The m+1-th turn is disposed between the m?1-th turn and the m-th turn. Further, in a cross-section perpendicular to a central axis and passing a tooth, an angle between a line segment connecting respective centers of the m+1-th turn and the m?1-th turn and a line segment connecting respective centers of the m+1-th turn and the m-th turn is about 120° or more. With this structure, bulging in a circumferential direction of the coil adjacent to an inner peripheral portion of the tooth can be suppressed and a clearance can be secured between adjacent coils such that the number of turns of the coil can be increased.

  • Publication number: 20060117886
    Abstract: In a parallel shaft-type of conical-geared transmission apparatus, a conical pinion is fitted to a first rotation shaft, and a second rotation shaft is arranged in parallel to this first rotation shaft. A conical wheel meshing with the conical pinion is fitted to the second rotation shaft. The pinion and the wheel are substantially equal in cone angle. A supporting device supports the first rotation shaft to be movable in the axial direction. A pressing device applies thrust in the axial direction of the first rotation shaft. A load bearing body to bear the thrust applied by the pressing device and to allow the first rotation shaft to be displaced in the radial direction is provided at an end of the first rotation shaft.

  • Patent number: 6913055
    Abstract: A lamination system comprises a thermocompression bonding means for bonding laminate films on top and/or back surfaces of cards, applying heat and pressure using a pair of heat rollers. The lamination system is provided with contact type temperature detection devices for detecting surface temperatures of the heat rollers and a heat roller attaching/detaching device for attaching or detaching the heat rollers. The heat roller attaching/detaching device places the temperature detection devices in contact with surfaces of the heat rollers when the heat rollers are being installed in the lamination system, and places the temperature detection devices apart from the heat rollers when the heat rollers are to be attached to, or detached from, the lamination system.

  • Patent number: 6883573
    Abstract: In a lamination system for laminating a film with a heat adhesive layer on at least a surface of a plastic card applying heat and pressure by heat rollers, each of two rectification devices for rectifying warp in the laminated card is provided independently of each other, at the downstream of the heat rollers, respectively along each of sides of the card along card transfer direction. Each of the rectification devices comprises a pair of rotatable rollers.
