Abstract: In a liquid-cooling system for a notebook personal computer having a body part including a CPU and a chip set respectively mounted on a mother board and an HDD, and a display part rotatably supported by the body part, a heat receiving head is fixed to at least one heat generation part including the CPU. A tube filled with cooling liquid is connected to the heat receiving head. The tube connected to the heat receiving head is disposed in series on at least one heat generation part including the chip set so as to collect the heat generated from each heat generation part. The tube is also laid in a meandering or zigzagging pattern between a liquid crystal panel and a housing of the display part. The heat generated from each heat generation part is absorbed at part of the tube by the cooling liquid that circulates in the tube and functions as a heat transfer medium. The absorbed heat is then radiated at another part of the tube.

Abstract: In an electronic equipment or apparatus, having water-cooling structure able to circulate/supply a cooling liquid with stability, for dealing with an increase of heat-generation of a heat-generating element, accompanying with an increase of processing performances, a pipe, which is located at a side where the cooling water flows out from a tank building up the water-cooling system, is extended up to the position of a center of the tank and disposed therein. Also, two (2) pieces of plates are provided for dividing the vicinity of an inlet portion of a pipe, through which the cooling water flows out, within the tank, and further, when injecting the cooling water into the tank, an injection jig for the cooling water is used, which has a connector portion with the tank.

Abstract: A plurality of electronic apparatuses, each apparatus having a closed loop cooling system, are installed in a cabinet having another closed loop fluid cooling system. Each of the closed loop fluid cooling systems includes a heat receiver and a pump. A projection is mounted on the electronic apparatus and a switching valve is arranged on the cabinet to stop or start circulation of a cooling fluid.

Abstract: In a disk drive system, a data transducer control during a seek operation is based on the distance to be traversed. Acceleration of a motor coupled to the head initiates movement of the head. Deceleration of the motor is initiated based on the distance traversed by the head.

Abstract: In a disk drive, since high-frequency repeatable runout (RRO) components own low correlative relationships between adjoining tracks, a servo control system of a magnetic head is followed to the high-frequency RRO components, and thus, in the worst case, there is a possibility that data which have been previously recorded on these tracks are destroyed. To avoid this problem, both a tracking type repetitive control unit which is followed to low-frequency RRO components, and a rejection type repetitive control unit which cancels the high-frequency RRO components are provided in a following control loop in order that the following control system is not unnecessarily followed to the high-frequency RRO.

Abstract: In a magnetic disk device and other memory devices, the scale and cycle of disturbance applied to each memory device are monitored to make a distinction between a harmful shock and harmless vibrations and detect the disturbance. Values at at least two points, of a waveform signal corresponding to the disturbance are captured. A) The above distinction is carried out from the size or magnitude of the inclination of a straight line defined by the two points. B) The function of capturing and storing the waveform signal corresponding to the disturbance as digital data, and outputting a slice level value for providing suitable detection sensitivity from a conversion table based on the digital data, or correcting and adjusting it and outputting the result is further set.
