A semiconductor package for use in computers includes a insulating substrate onto which a semiconductor device is mounted, an insulating cap which shuts out outside air and seals said semiconductor device, power-source lines which provide power to the semiconductor device, and signal lines which transmit output signals from the semiconductor device to external circuits. The signal lines are arranged perpendicularly to the insulating substrate so that they are prevented from the dielectric constant of the insulating substrate, while the power-source lines are formed within the insulating substrate and connected through conductive layers parallel to the surface onto which the semiconductor is mounted to external leads.

A heat conducting member is placed in the space between a semiconductor chip which generates heat and a heat transfer block which is cooled by a coolant, and the heat conducting member conducts heat from the semiconductor chip to the heat transfer block. The heat conducting member has a slanted surface which is inclined with respect to a surface to be cooled of the corresponding semiconductor chip. Even when the semiconductor chip is displaced or inclined with respect to the heat transfer block, the whole of the cooling surface of the semiconductor chip can be kept in contact with the corresponding heat conducting member.

A wire holder capable of facilitating adjustment and/or variation of a length and tension of the wire. The wire holder includes a wire grip and a connector. The connector is formed on an outer surface thereof with a groove longitudinally extending from an upper end portion thereof to an intermediate portion thereof and laterally extending from a substantially central portion of the connector to the outer surface of the connector in the manner that a bottom surface of the groove is smoothly curved so as to gradually decrease a depth of the groove toward a lower end portion of the connector and toward the outer surface of the connector.

Display apparatus having a rail fixable on a stationary structure and provided with a groove, a sliding member fittable in the rail groove and slidable therealong, a wire or cord coupled to the sliding member, a gripping member through which the wire or cord passes, a supporting hook connected to an end of the wire or cord remote from the gripping member, and a second rail having a groove for receiving the hook such that the wire or cord is coupled to the second rail and is tensioned when installed. The gripping member through which the wire or cord passes, comprises a hollow member having an inner tapered surface, a sleeve member having a passage formed therein for the wire or cord and situated within the hollow member to be freely slidable with respect thereto with at least a portion of the sleeve member projecting out from the hollow member, and at least one ball captured in the sleeve member seating against the tapered inner surface of the hollow member and communicating with the passage. A spring urges the sleeve member in a direction in which the inner surface of the hollow member tapers.
摘要:
The present invention relates to the development of an alloy material with significantly improved low-temperature brittleness, recrystallization brittleness, and irradiation brittleness by the introduction of a recrystallization microstructure into an alloy, particularly a tungsten material, to significantly strengthen a weak grain boundary of the recrystallization microstructure. The present invention comprises the steps of: mechanically alloying at least one species selected from a group-IVA, VA, or VIA transition metal carbide and a metallic raw material; sintering base powders obtained through the mechanically alloying step, by using a hot isostatic press; and performing plastic deformation of at least 60% on the alloy obtained through the sintering step, at a strain rate between 10−5 s−1 and 10−2 S−1 and at a temperature between 500° C. and 2,000° C. It is therefore possible to obtain an alloy material with significantly improved low-temperature brittleness, recrystallization brittleness, and irradiation brittleness.
