Abstract:
The mounting structure of a power device is simplified so as to reduce cost while achieving improvements in heat dissipation and reliability. A power module 100 is comprised of a metal wiring board 13, a power device 11 disposed on an upper surface of the metal wiring board 13 via a solder layer 12, a metal heat dissipating plate 15 disposed on a lower surface of the metal wiring board 13, and a heat sink 19 disposed on a lower surface of the metal heat dissipating plate 15. A resin-based insulating layer 14 is disposed between any desired two of the aforementioned layers.
Abstract:
A proton conducting polymer is formed by the copolymerization of a plurality of compounds, including a silicon compound comprising an organic chain, and a compound including at least one acid group. The polymer comprises a hybrid organic-inorganic matrix having acid groups linked through a linking group. The linking group may include one or more electron withdrawing groups. The electron withdrawing group may be a halogen.
Abstract:
A composition suitable for slush molding comprising a thermoplastic polyurethane elastomer (A) having a number average molecular weight of 10,000 to 50,000 and a heat softening initiation temperature of 120 to 200° C., a plasticizer (B), a compound (C) containing a radical polymerizable unsaturated group, and optionally an additive. The composition provides a molded article excellent in durability such as thermal/light aging resistance, soft touch at low temperature, and appearance.
Abstract:
In an air bag apparatus for a passenger seat, an air bag door has three layers: a door base member, a shell and a foam layer charged between the door base member and the shell. A groove-shaped rib is formed in a rearward end-side portion of the door base member of the air bag door. A grommet is fixed at each of the opposite ends of the rib. A strap formed of a looped resin-made cord formed by knotting the two end portions of the cord is laid in the rib, extending through the grommets. The strap is covered with a heat-shrink tube that prevents degradation of the strap due to influence of a component material of the foam layer.
Abstract:
A composition suitable for slush molding is disclosed. The composition is mainly comprised of a thermoplastic polyurethane elastomer (A) with a number average molecular weight of 20,000 to 50,000 and a glass transition point of not higher than -35.degree. C., a plasticizer (B), a blocked polyisocyanate (C) and a pigment (D), wherein each of(B), (C) and (D) is respectively contained in a prescribed quantities. The polyurethane-type slush molding composition provides a molded article of low hardness, high elongation at low temperature, and excellent thermal aging resistance and light aging resistance.
Abstract:
A vehicle interior member with an air bag includes an air bag door portion that can be made to be invisible and of improved construction. The vehicle member includes a skin molded to a substrate. The skin includes a tear line formed by a diagonal cut portion. In the vicinity of a lateral tear line of the skin side tear line, a projecting portion is provided on a lower mold to form a groove portion of the substrate along the diagonal cut portion so as to intercept a flow of a resin from the cutting direction of the diagonal cut portion. Therefore, as the resin flows in a reverse direction to the cutting direction of the diagonal cut portion at an opening portion thereof, a flow of the resin into a polypropylene foam layer of a three-layer skin through the opening portion of the diagonal cut portion can be suppressed. This prevents the polypropylene foam layer from being melted and damaged.
Abstract:
A battery, such as a lithium-ion battery, comprises a first electrode, a second electrode, a molten salt electrolyte, and an electron collector, associated with the first electrode, the electron collector comprising an electrically conducting film. The battery further includes a protection layer separating the electron collector and the first electrode, the protection layer comprising a carbon-containing material. The electron collector may be an electrically conducting material such as aluminum, aluminum alloy, copper, nickel, other metal (such as alloys), conducting polymer, and the like. In one example, the protection layer is a graphite layer. In other examples, the protection layer may be a fullerene film, carbon nanotube film, or other carbon-containing material.

This prevents the PP foam layer from being melted and damaged.
