    摘要: An optical pickup device comprises a semiconductor laser that causes outgoing of laser beam used for reproduction and recording of information on an optical disk, and an objective lens that conducts the laser beam outgoing from the semiconductor laser to the optical disk. The objective lens is driven by a yoke, a focusing coil, a tracking coil, etc. These elements are accommodated in a pickup housing. First and second bearing portions supporting the pickup housing to make the same movable are attached to the pickup housing and arranged on both sides with the objective lens therebetween. The yoke is thermally connected to the first bearing portion positioned on an opposite side of the yoke to the semiconductor laser.

    摘要: An electronic apparatus, such as a blade server or the like, has a cooling system for efficiently cooling a plurality of heat generating semiconductor devices, such as a CPU, mounted on blades which is freely put on and taken off. The cooling system includes a thermosiphon which transfers heat from devices having relatively high heat generation, such as CPU or the like, to the outside of the apparatus, heat pipes which transfer heat of devices having relatively low heat generation to the thermosiphon, a thermal highway which is thermally coupled to the thermosiphon by the mounting of blades into a housing and collects and transfers the heat from the thermosiphon and the heat pipes, and a condenser which transfers the heat collected and transferred by the thermal highway outside a housing.

The server module includes an enclosure accommodating therein a motherboard on which a CPU, memory, and the like are mounted, and part of a boil cooling device for cooling heat generated by the CPU. A fan accommodated in a fan module is adapted to blow air into the server module through an opening of the server module enclosure. The boil cooling device includes a first heat transmission member disposed in the server module enclosure, a second heat transmission member disposed outside the server module enclosure, and a plurality of pipes connecting them. The first heat transmission member is a box body with an internal space for hermetically sealing a refrigerant therein, one external planar face of which is thermally connected to the CPU and the other external planar face of which is provided with a heat sink. The second heat transmission member is disposed in the fan module unit, and a heat radiation member provided for the pipes forms an airflow passage together with the motherboard.

    摘要: The voltage output terminals of a semiconductor integrated circuit are connected to the first ends of resistors while the second ends of the resistors are connected to a common signal line. Taking advantage that the potential of the signal line presents the mean voltage value of the voltages output from all the voltage output terminals, the deviation of the potential at each voltage output terminal from the mean value and the difference of this mean value from the ideal value are determined, whereby the suitability of the output voltage from each of the output terminals is examined.
