Abstract: According to an embodiment of the present invention, there is provided a heat spreader including an evaporation portion, a first condenser portion, a working fluid, and a first flow path. The evaporation portion is arranged in a first position. The first condenser portion is arranged in a second position, the second position being one of higher than and apart from the first position. The working fluid evaporates from a liquid phase to a gas phase in the evaporation portion, and condenses from the gas phase to the liquid phase in the first condenser portion. The first flow path is made of a nanomaterial, has hydrophobicity on a surface, and causes the working fluid condensed to the liquid phase in the first condenser portion to flow to the evaporation portion.

Abstract: PROBLEM TO BE SOLVED: To provide a pump device capable of keeping airtightness high and stably and efficiently pressure-feeding fluid and to provide a cooling apparatus equipped with the pump device. SOLUTION: The pump device 10 has, in a housing 1 connected to a pipe 20 through which the fluid can flow, a check valve 6, a movable body 2, a bellows supported at opposite ends by check valve 6 and the movable body 2, and a coil spring 5 supporting the movable body 2 and the bellows 8 on an inner wall of the housing 1. The movable body 2 is provided with a magnet 4 and a check valve 7. A coil 3 is provided on an outer periphery of the housing 1 for reciprocating the movable body 2 including the magnet 4 in a flow direction of the fluid. When the bellows 8 is expanded through reciprocation of the movable body 2, pressure in the bellows is decreased and the fluid flows in from the pipe 20 through an opening portion 1b and the check valve 6. When the bellows is constricted, the pressure in the bellows 8 is increased and the fluid flows out through the check valve 7 and an opening portion 1d. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide desired heat transportation capability even at any attitude. SOLUTION: Even when an evaporator is arranged below a condenser and heat load is not applied to the evaporator, working fluid 19 is held by capillary tube force of a channel 14a in the condenser as shown in Fig. 6 (B) to prevent the working fluid 19 from flowing out onto an evaporator side. Consequently, only liquid phase working fluid exists in a liquid phase tube always. As a result, it is possible to prevent running-out of liquid or drying-out when the heat transportation device operates to obtain desired heat transportation capability. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PURPOSE:To make level adjustments of high quality which are small in initial distortion rate and level variation even if operation modes are switched. CONSTITUTION:A controller 31 stores a backup RAM 24 with the control value from a control value calculation unit 70 right before the modes are switched with a mode changeover switch 32, and uses the control value stored in this backup RAM 24 as the initial value of an attenuator 83 after the mode switching.

Abstract: PROBLEM TO BE SOLVED: To provide a heat transport apparatus which carries out large capacity heat transport while the apparatus is miniaturized and thinned, and also to provide an electronic instrument mounted therewith.
SOLUTION: A plurality of first tabular bodies 17 arranged in a direction substantially orthogonal to both of an arrangement direction of a cover plate 9 and a base plate 10, and an arrangement direction of an evaporator 3 and a condenser 5, is provided to form a first gap 18 for communicating a condensed working fluid to the evaporator 3. Accordingly, capillary force is easily increased by narrowing intervals between the first tabular bodies 17, and reducing the first gap 18. It is also easy to reduce a thickness in the arrangement direction of the cover 9 and the base plate 10 comprising a casing 2 by numerously arranging the plurality of first tabular bodies 17 in its arrangement direction.
