  • Patent number: 9866084
    Abstract: A core segment sub-assembly has a first holding groove, which holds a start part of a coil wire of a three-phase winding, and a second holding groove, which holds an end part of the coil wire of the three-phase winding, at positions on an axial end surface of an annular covering part and shifted in a circumferential direction relative to a tooth covering part, on which the winding is provided. The first holding groove and the second holding groove sandwiches the tooth covering part and are separated more from each other as extending in a radially outward direction. The positions and the directions of the first holding groove and the second holding grooves are matched to the paths of the coil wire wound by a flyer type winding machine. The stator can thus be made suited to a winding process by the flyer type winding machine.

  • Patent number: 8875020
    Abstract: A portable information processing apparatus includes a replay processing unit that replays content data, a synchronous display unit that selects a piece of associated information corresponding to a replayed portion of the content data, and instructs to display the associated information thus selected, and an output controlling unit that displays the associated information that is selected by the synchronous display unit in an associated information display area arranged in a display unit. The synchronous display unit selects the associated information other than the one corresponding to the replayed portion and instructs the output controlling unit to display the information, upon accepting an operation requesting to display associated information other than the one corresponding to the replayed portion.

  • Patent number: 8419280
    Abstract: Provided is a thin slide unit which allows, in a case where two ball plates each formed with a track-like ball groove are combined to thereby construct an endless circulation path for balls, by merely directly connecting the two ball plates without using a guide plate, balls to smoothly circulate, and a slider to smoothly reciprocate with respect to a guide rail. An endless circulation path for the balls of the slider is formed such that the two ball plates each formed with the track-like ball groove are caused to face each other, and that the ball plates are directly connected. Peripheral sides of the two ball plates oppose to each other, to thereby form a load opening portion for causing the balls in the endless circulation path to contact a rolling groove of the guide rail, and form a scooping-up portion for raising the balls from the rolling groove to guide the balls into the endless circulation path.

  • Patent number: RE43657
    Abstract: An electronic device that prevents a failure caused by a temperature drift of an angular velocity sensor, and a signal compensation system and a signal compensation method for compensating for the temperature drift are provided. The present invention provides a mechanism including an angular velocity sensor that outputs a first signal in accordance with a rotational angular velocity. The device stores in advance data of a second signal normally output by the angular velocity sensor while in a stationary state, detects a stationary state and extracts the difference between the first and second signals when the stationary state is detected. The device thereby compensates for the first signal based on the extracted difference signal. A display unit in the device scrolls an image based on the compensated signal. This prevents a failure caused by the temperature drift of the angular velocity sensor.
