Abstract:
A resin composition comprising predetermined amounts of a specific polyamide resin (A), a modified polyphenylene ether resin (B), a fibrous inorganic filler (C) having an average fiber-diameter of 10 .mu.m or less, a powdery inorganic filler (D) having an average particle diameter of 10 .mu.m or less, an epoxy resin (E) and a copper compound (F-1) and/or a powdery phenolic resin (F-2); a molded article formed from the resin composition; and a lamp reflector formed from the molded article. The molded article formed from the above resin composition can give an automotive lamp reflector excellent in resistance to heat generated when a lamp is on, rigidity at high temperatures, clear reflection performance on a mold article surface, adhesion to deposited aluminum and adhesion to a primer coating composition.
Abstract:
A semiconductor device includes first and second trenches, and a first layer provided therebetween, in a principal surface of a semiconductor substrate, a second layer in contact with and sandwiching the first trench with the first layer, a third layer provided under the second layer and in contact with the second layer and the first trench, a fourth layer provided under and in contact with the third layer but separated from the first trench, and a fifth layer provided in the principal surface and sandwiching the second trench with the first layer. The second and fourth layers are semiconductors of a first conductivity type, and the first, third, and fifth layers are semiconductors of a second conductivity type. A gate trench electrode is provided inside the first trench via the insulating film, and an emitter trench electrode is provided inside the second trench via the insulating film.
Abstract:
A leakage current of the MOS transistor of a power control section at a standby time is drastically reduced and the reduction of the consumption power is achieved. A memory module is provided with power control sections. When either of the memory mats is not selected, the power control sections stop the power supply voltage to a non-selected memory mat, a word driver, an input-output circuit, a control circuit and an output circuit. At the standby time of the memory module, the power control section stops a power supply to power control sections, a control circuit, a predecoder circuit, and an input circuit. In this manner, the leakage current of the MOS transistor of the power control sections at the standby time can be drastically reduced.
Abstract:
There is disclosed a polyamide resin composition comprising (A) 100 parts by weight of a polyamide (a) composed mainly of a xylylenediamine component and an .alpha.,.omega.-straight chain asphaltic dibasic acid component, or a combination of the polyamide (a) and polyamide 66, (B) 1 to 15 parts by weight of polyamide 12, (C) 0.01 to 5 parts by weight (in terms of copper) of a copper compound, (D) 1 to 15 parts by weight of carbon black, and (E) an alkali metal halide of such an amount that the number of halogen atoms of the alkali metal halide is 0.3 to 4 per one copper atom of the above copper compound. Said polyamide resin composition has an excellent weather resistance, moldability, and mechanical properties, and can be injection-molded.
Abstract:
A pneumatic tire is provided including a multiplicity of land portions 3A, 3B, 3C, 3D, and 3E formed by main grooves 2 extending linearly in the tire width direction partitioning the tread surface 1, and having a designated mounting direction on a vehicle. Among the multiplicity of land portions 3A, 3B, 3C, 3D, and 3E, lug grooves are not provided in a ground contact region R of the land portions 3A and 3E positioned on both shoulder sides. Lug grooves 4 inclining in the tire circumferential direction that have terminating parts in the land portions and opening to the main groove 2 on the vehicle inner side are formed at specified intervals in the tire circumferential direction in the land portions 3B and 3D inwardly adjacent to the land portions on both shoulder sides.
