Abstract: A box-shaped enclosure of a storage box includes a deadening wall or walls defining a storage space between first and second planes. The storage space is open at the first and second planes. A deadening wall member extends along the first plane. An auxiliary box-shaped enclosure is connected to the box-shaped enclosure so as to close the first plane of the box-shaped enclosure. The auxiliary box-shaped enclosure defines an auxiliary space isolated from the storage space with a deadening wall member. The storage space is connected to the fresh air through the ventilation opening and the auxiliary space. The deadening wall or walls of the box-shaped enclosure and the deadening wall member serve to prevent the leakage of the operating sound.

Abstract: A support member is designed to move in the longitudinal direction in a rack mount type disk array apparatus. A frame member is attached to the support member for relative rotation around the rotation axis located between the front and rear ends of the frame member in the longitudinal direction. Recording disk drives are held within the frame member in an upright attitude. The recording disk drives can be removed from and inserted into the frame member in a facilitated manner. This leads to a facilitated replacement of the recording disk drives. Moreover, the upper face of the frame member is allowed to face forward through the rotation around the rotation axis. Even if the disk array apparatus is placed at a higher level, the operator easily accesses the recording disk drives in the frame member.

Abstract: A refrigeration system allows the refrigerant to circulate through a closed circulation channel. A dry evaporator is incorporated in the circulation channel. The dry evaporator is designed to keep a quality smaller than 1.0 in evaporating the refrigerant. The quantity of heat transfer per unit area, namely, a heat transfer coefficient depends on the quality. The heat transfer coefficient remarkably drops when the quality of the refrigerant exceeds a predetermined threshold level before the quality actually reaches 1.0. The quality of the refrigerant kept below the predetermined threshold level during vaporization of the refrigetant in the dry evaporator allows a reliable establishment of a higher performance of cooling. On the other hand, if a refrigerant completely evaporates in a dry evaporator in a conventional manner, the heat transfer coefficient of the refrigerant remarkably drops after the quality of the refrigerant exceeds the predetermined threshold level.

Abstract: A heat conductive fluid is interposed between an electronic component and a heat sink. The heat conductive fluid serves to enhance the contact between the surface of the electronic component and the opposed surface of the heat sink. The heat conductive fluid also exhibits the property of adsorption between a pair of surfaces based on the fluidity of the heat conductive fluid itself. Although the adsorption allows the slippage of the heat sink along the surface of the electronic component, the adsorption reliably restrains the heat sink from moving in the perpendicular direction perpendicular to the surface of the electronic component. The atmospheric pressure solely acts on the heat sink so as to urge the heat sink against the surface of the electronic component. No excessive urging force is applied to the electronic component.

Abstract: In an electronic device that contains a cooling system in which the refrigerant circulates through both the base and the heat-radiator and the heat-radiator is installed away from and to the side of the heat-generator, the heat-generator is positioned on top of the base. This means that the height of the base in the electronic device becomes relatively low, and so the height of the heat-radiator—which must be installed above the height of the base—can be increased, meaning that the required heat-radiating region can be secured and high-performance cooling becomes possible.
