  • Patent number: 8112853
    Abstract: A method of manufacturing a capacitor-integrated busbar includes disposing a pair of metal conductors having surfaces facing each other with a gap lying therebetween, injecting a resin material in a fluid state into the gap between the metal conductors disposed to face each other, and forming a plate-like resin by hardening the injected resin material.

  • Publication number: 20100296224
    Abstract: A capacitor formed by winding a multilayer film in which an insulation film, a cathode, electrode, an insulation film and an anode electrode) are serially multilayered, wherein at least one of first insulation film and second insulation film is formed so that an end portion of insulation film on an inward side of the capacitor has a thickness larger than a thickness of an end portion thereof on an outward side of the capacitor.

  • Patent number: 7820279
    Abstract: A resin-metal composite layer is formed by modifying a surface of a resin substrate to a modified layer, contacting the modified layer with a metal compound solution, and adsorbing at least either metal colloids or ions are adsorbed to the polar group, so that metal particles are dispersed into the modified layer. Because of the fineness of the metal particles in the resin-metal composite layer, high transparent can be achieved. The resin-metal composite layer functions as a transparent conductive layer and the like.

  • Publication number: 20100165680
    Abstract: An inverter module has a first inverter driving a first electric load and a second inverter driving a second electric load, mounted on a common insulation substrate. In the first inverter, the arms of the U, V and W phases are arranged on the insulation substrate such that arms adjacent in the horizontal direction in the drawing are located displaced from each other in the vertical direction in the drawing. In the second inverter, the arms of the U, V and W phases are arranged on the insulation substrate such that arms adjacent in the horizontal direction in the drawing are displaced from each other in the vertical direction in the drawing. Moreover, the arm of the first inverter and the arm of the second inverter are arranged to be adjacent along the horizontal direction in the drawing. By such an arrangement, the in-plane temperature distribution can be rendered uniform without having to increase the area occupied by the insulation substrate.

  • Publication number: 20100132193
    Abstract: A power conversion device according to the present invention includes a power conversion circuit having a switching element and converting DC power to AC power, a capacitor-integrated busbar, and a housing accommodating the power conversion circuit and the capacitor-integrated busbar. The capacitor-integrated busbar includes a highly dielectric plate-like resin having a resin material as a base material, and a pair of metal conductors having a facing region where the metal conductors face each other, the facing region being joined to opposing surfaces of the plate-like resin. The plate-like resin and the pair of metal conductors of the capacitor-integrated busbar form a capacitor. The power conversion circuit is supplied with power via the metal conductors.

  • Publication number: 20100066166
    Abstract: In a hybrid vehicle, rocker outer reinforcements serving as vehicle side frame members in a vehicle width direction extend in a vehicle front-rear direction. An electric power cable is provided such that a portion thereof along the vehicle front-rear direction is placed along an inner side surface of the rocker outer reinforcement in the vehicle width direction. An electric power cable is provided such that a portion thereof along the vehicle front-rear direction is placed along an inner side surface of the rocker outer reinforcement in the vehicle width direction. Further, each of the electric power cables is placed in a space portion formed between the rocker outer reinforcement and a center body pillar serving as an energy absorbing member absorbing energy in the event of a side collision of the vehicle.

  • Publication number: 20060042954
    Abstract: This invention provides a method for plating a resin material that improves adhesion strength between a resin material and a plated metal layer and reduces the cost incurred by plating. This method comprises a step of treating a resin material with ozone water and a step of permitting the resin material to adsorb at least one metal catalyst selected from the group consisting of silver, cobalt, nickel, ruthenium, cerium, iron, manganese, and rhodium catalysts.
