  • Patent number: 11116262
    Abstract: A garment includes a covering fabric; padding to be filled inside the covering fabric; and quilting stitches. The padding is constituted by polyester staple fibers including fibers having a circular outer peripheral cross section and has an open fiber structure. The fibers constituting the padding have an irregular diameter, and a smoothing agent is fixed to surfaces of the fibers. Thus, it is possible to provide a garment free from problems of uneven distribution of padding and having favorable water removability at the time of washing, quick dryability, and a favorable sliding property between fibers. This garment is suitable as a garment for sports to be washed repeatedly. Further, since the garment can be worn in a puffy state even when wet, it dries quickly by the body heat.

  • Patent number: 10498203
    Abstract: A laminated rotor core (36) wherein permanent magnets (47) are inserted in respective magnet insertion holes (46) is disposed between and pressed by an upper die (37) and a lower die (29). The upper die (37) has resin reservoir pots (50) provided above the laminated rotor core (36) and at positions corresponding to the respective magnet insertion holes (46). Raw resin material put in the resin reservoir pots (50) is heated by the upper die (37). Subsequently, the resin material in a liquefied state is ejected from the resin reservoir pots (50) by plungers (52) that are inserted and moves vertically in the resin reservoir pots (50) and is directly filled in the magnet insertion holes (46). Consequently, the respective magnet insertion holes (46) are filled with the resin material more evenly and highly reliable products can be supplied at low cost.

  • Patent number: 10472753
    Abstract: A bobbin thread winder of a sewing machine including a bobbin winder spindle holding a bobbin and a driving mechanism to apply a drive force to the bobbin winder spindle, comprises a time measuring unit to measure an bobbin-thread winding execution time with respect to the bobbin, and a bobbin-thread winding amount calculating unit which calculates a winding amount of the bobbin based on the bobbin-thread winding execution time with respect to the bobbin measured by the time measuring unit. In the bobbin thread winder, since the bobbin-thread winding execution time was measured by the time measuring unit, and the bobbin winding amount of the bobbin is calculated based on the bobbin-thread winding execution time by the bobbin-thread winding amount calculating unit, it is possible to detect the bobbin winding amount of the bobbin accurately regardless of the type and thickness of the bobbin thread.

  • Publication number: 20180271182
    Abstract: A garment of the present invention is a garment (1) including: a covering fabric; padding to be filled inside the covering fabric; and quilting stitches (2a, 2b). The padding is a polyester staple fiber cotton including fibers having a circular outer peripheral cross section and has an open fiber structure. The fibers constituting the padding have an irregular diameter, and a smoothing agent is fixed to surfaces of the fibers. Thus, it is possible to provide a garment free from problems of uneven distribution of padding after repeated washing, fatigue, etc., and having favorable water removability at the time of washing, quick dryability, and a favorable sliding property between fibers even though synthetic fiber cotton is used as the padding. This garment is suitable as a garment for sports to be washed repeatedly. Further, since the garment can be worn in a puffy state even when wet with sweat, rain, snow, water, etc., it dries quickly by the body temperature and prevents the coldness of the body.

  • Publication number: 20160103478
    Abstract: According to embodiments, a second control unit creates parity from information loaded into a volatile second memory. When shifting from a normal mode to a sleep mode, the second control unit stores the created parity and the information loaded in the second memory into a buffer of a non-volatile first memory, and issues a power supply shutdown request. A power supply circuit shuts down power supply to the second memory and the second control unit in response to the issued power supply shutdown request.
