  • Patent number: 12163712
    Abstract: A heat-source-side heat exchanger is divided so that a heat-source-side heat exchanger that functions as an evaporator also functions as an intermediate cooler. Since, when an air conditioner includes a bypass pipe, a heat-source-side heat exchanger that functions as an evaporator and as an intermediate cooler also further functions as a radiator, operation efficiency is increased.

  • Publication number: 20240328964
    Abstract: To provide an X-ray inspection apparatus capable of obtaining a clear transmission image with less noise without reducing a conveyance speed of an inspection object. There is provided an X-ray inspection apparatus in which an X-ray generator and an X-ray detector are disposed to face each other with a conveyance path interposed between the X-ray generator and the X-ray detector, conveyance path through which inspection objects that are sequentially conveyed pass. The X-ray generator and the X-ray detector are configured to move back and forth in a conveyance direction of the inspection object and an opposite direction thereof. The X-ray detector captures an image of the inspection object while the X-ray generator and the X-ray detector moves in the conveyance direction from an image capturing start position to an image capturing end position at a speed equal to the conveyance speed of the inspection object.

  • 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: 9476394
    Abstract: A motor includes a stator with a bobbin. The bobbin has a lower end winding portion, a head part retainer portion that retains a head part of a winding, and a control portion disposed between the lower end winding portion and the head part retainer portion. A head part retainer surface formed on a pump part side of the head part retainer portion and an end face formed on a pump part side of the control portion are positioned on the same plane and on a pump part side relative to a winding retainer surface that is formed on a pump part side of the lower end winding portion. Thus, when the winding is wound in layers onto the winding retainer surface of the bobbin, collapsing of a middle part of the winding onto the head part of the winding is prevented.

  • 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.
