A cooling apparatus comprises a tank for keeping a coolant liquid therein and having an air layer, a heat receiving element in contact with a heat generating part to receive heat therefrom, a radiator for radiating heat absorbed by a coolant liquid, and a circulating mechanism for circulating the coolant liquid from the heat receiving element through the tank and through the radiator again to the heat receiving element. The tank has a conduit forming area for forming a coolant liquid circulating conduit to pass through a middle position of the tank, and a narrow gap which divides the conduit forming area at the middle position of the tank.

The present invention provides a backlight device which uses solid-state light emitting elements capable of emitting lights of three colors consisting of red, green and blue as a light source, can enhance the light utilizing efficiency, and can be made light-weighted. Further, the invention provides a display device which exhibits the high brightness uniformity and the high chromaticity uniformity. The backlight device includes a main light guide plate which has a light irradiation surface which irradiates light forwardly by developing the light in plane and has a light reflection surface which faces the light irradiation surface in an opposed manner and reflects the light toward the light irradiation surface; a sub light guide plate which is arranged on a back surface of the main light guide plate, is divided into a first sub light guide plate and a second sub light guide plate on both end sides by way of a first air layer disposed at a center portion, and forms light incident surfaces on facing end surfaces of the first sub light guide plate and the second sub light guide plate in the inside of the first air layer; a first light reflection plate which is arranged on a front surface of the sub light guide plate which faces the main light guide plate; a second light reflection plate which is arranged on a back surface of the sub light guide plate which faces the first light reflection plate in an opposed manner; reflectors which are arranged on both end surfaces of the main light guide plate and the sub light guide plate and optically couple the main light guide plate and the sub light guide plate; and a light emitting diode board which is mounted in a state that the light emitting diode board faces a back surface of the sub light guide plate and light emitting diodes capable of emitting light of plurality of colors in the inside of the first air layer are arranged at least in a row. Due to such a constitution, a light-source light from the light emitting diodes capable of emitting lights of plurality of colors is subjected to color mixture and an effective optical path can be elongated and hence, the light utilizing efficiency can be enhanced and, at the same time, the backlight device can be made light-weighted.

An illumination apparatus includes: a light guide plate composed of a plurality of aligned blocks; and a plurality of light sources, each being provided for one of the blocks and emitting light to the one block. A gap of 0.1 microns or more is formed in at least part of a region between the adjacent blocks. An inside of the gap serves as an air layer.

The present invention provides a display device comprising a display panel and a backlight device comprising a main light guide body which irradiates light toward the display panel. A sub light guide body is arranged on the back surface of the main light guide body is divided in the center by a first air layer. Both end portions of the sub light guide are optically coupled to the main light guide, and a plurality of solid state light emitting elements are arranged in the inside of the air layer of the sub light guide.

A die pickup method and apparatus that uses a tape peeling stage which supports a portion of an adhesive tape that corresponds to a die to be picked up, and a suction holding stage in which suction holding holes that, with vacuum suction, holds areas of the adhesive tape that surround the die to be picked up, thus separating the die from the adhesive tape by forming an air layer between the die and the adhesive tape, and then picking up the die. The air layer is formed, with the die being held via vacuum suction by a suction nozzle provided above the suction holding stage, by raising the tape peeling stage and then by moving the tape peeling stage horizontally in a direction away from the die.

An electromagnet comprises a pair of magnetic pole 1a and 1b, a return yoke 3, exciting coils 4 and 5, etc. In an interior portion of a magnetic pole, plural spacers 2a-2g are provided putting side by side in a horizontal direction. Each of the spaces 2a-2g is an air layer and a longitudinal cross-section is a substantially rectangular shape and the space has a lengthily extending slit shape in a vertical direction against a paper face in FIG. 1. The plural spaces are mainly arranged toward a right side from a beam orbit center O and an interval formed between adjacent spaces is narrower toward the right side. The electromagnet having a simple magnetic pole structure and a wide effective magnetic field area in a case where a maximum magnetic field strength is increased can be secured.

The present invention provides a portable computer in which an increase in temperature of a housing is suppressed. In the present invention, a guide plate is provided to suppress an increase in temperature of a bottom surface. When a cooling fan device operates, outside air taken in from inlet openings flows as an air current through a narrow flow path formed between the guide plate and the bottom surface. A flow velocity of the air current can be increased by narrowing the flow path, and heat exchange with the guide plate can be effectively performed, thereby sufficiently cooling a cooling surface. The cooled guide plate cools an air layer between the guide plate and the heat sink and thermally insulates between the air layer and the bottom surface.
