  • Publication number: 20240343121
    Abstract: A drive device for a railway vehicle operates by receiving power supply from an alternating-current overhead contact line or a three-phase generator. The drive device for a railway vehicle is configured such that a voltage output from a main transformer is applied to alternating-current input ends in a converter circuit via a first switch. A first phase voltage among voltages output from the three-phase generator is applied to an alternating-current input end in a first leg of a brake chopper circuit via a second switch. Second and third phase voltages among the voltages output from the three-phase generator are applied to the alternating-current input ends, respectively, via the second switch.

  • Patent number: 10020096
    Abstract: A method for manufacturing a shielded wire harness, includes: wrapping a conductive sheet around a wire harness in a parallel state to the wire harness, the conductive sheet having a long belt shape along a longitudinal direction of the wire harness, and cutting the conductive sheet in matching with a desired electric wire length; allowing an adhesive surface formed on a back surface side of the protection tape to fix the conductive sheet to the wire harness by spirally winding a long protection tape around an outer circumference of the conductive sheet wrapped around the wire harness; and cutting the protection tape in matching with the desired electric wire length.

  • Patent number: 9633764
    Abstract: A conductive line shield structure includes a first conductive line and a shielding member. The first conductive line includes a conductive part and an insulative part. The shielding member is a sheet including an insulative base material and a metal foil, and is wrapped so as to enclose the first conductive line therein. One side end part of the shielding member overlaps an outside surface of the insulative base material so that one side end part of the insulative base material is in contact with the outside surface of the insulative base material.

  • Patent number: 8576567
    Abstract: A COF includes, in at least one embodiment, a heat dissipating material on a back surface of an insulating film. The heat dissipating material has a slit for reducing a degree of thermal expansion. Thus, at least one embodiment of the invention provides the COF in which deformation and disconnection of wiring are prevented.

  • Patent number: 8344486
    Abstract: In a COF of an embodiment of the present invention, the smaller distance to edges of a heat-releasing member an area of the heat-releasing member has, the larger openings the area has. Accordingly, a volume per area (an area per length) of the heat-releasing member decreases toward the edges. The arrangement improves flexibility of the COF. This prevents a stress caused by bending the COF from concentrating at the edges. This makes it possible to prevent a line on an insulating film from being broken. Also, it becomes possible to prevent an anisotropic conductive resin from coming off which is used to bond the COF with a display panel in providing the COF in a display apparatus.

  • Patent number: 8162724
    Abstract: A surface treating apparatus treats a substrate surface by rotating a cylindrical polishing member in a state where the polishing member makes contact with the substrate surface. A polishing liquid is supplied to a polishing liquid passage that is provided in a central portion of the polishing member, and the polishing liquid is supplied to the substrate surface by rotating the polishing member while filtering the polishing liquid by a foam member provided on an outer periphery of the polishing liquid passage. Aperture diameters of the foam member are larger on the side of the polishing liquid passage than on the outside of the polishing member.

  • Publication number: 20050208977
    Abstract: The information processing apparatus according to the present invention comprises a phone book database and a key input section. The phone book database stores the associations between phone numbers and keywords related to the phone numbers. The key input section contains keys to which characters and numerals are assigned. When a key is pressed, the information processing apparatus reads keywords, which begin with a character assigned to the pressed key, from the phone book database, and displays the read keywords. The information processing apparatus also displays a numeral that is assigned to the pressed key. When a selection is made to dial one of the displayed keywords, the information processing apparatus dials a phone number corresponding to the selected keyword. When keys in the key input section are repeatedly pressed, the numerals assigned to the pressed keys are displayed next to the currently displayed numeral.
