Abstract: PURPOSE: To prevent the generation of a solder bridge which is easily generated, when a component of a terminal of narrow pitch is soldered. CONSTITUTION: An excess solder absorption region 24 which is not provided with a solder resist 20 is provided to a tip side of a terminal 14, rather than to an end part 22A of a solder pad 22 in the solder resist 20. If much solder paste is attached on the solder pad 22 when the terminal 14 is soldered, excess solder 28 which is fused by the heat of a heating heater travels through a terminal 14 and flows to the tip direction of the terminal 14, inside an excess solder- absorbing region 24. Since the excess solder 28 does not go over the solder resist 20 between the terminals 14, a solder bridge is not formed.

Abstract: PROBLEM TO BE SOLVED: To provide a keyboard that a user can recognize the keys of a notebook personal computer even if it is used in the dark in an airplane and the like. SOLUTION: The keyboard 10 comprises a board 34, a membrane 30, an elastic member 17, a cover sheet 22, and key tops 12, all made of light transmitting material, and is also provided with a light emitting means 39 emitting light from under the board 34 toward the key tops 12. As the key tops are illuminated, the characters displayed on the key surfaces 56 of the key tops 12 become recognizable, so that a key operation error can be prevented. A thermoelectric generating element 42 is used as the power source for emitting the light from the light emitting means 39, so that the working time of the battery of the notebook personal computer is not reduced by the illumination.

Abstract: PROBLEM TO BE SOLVED: To keep uniform temperature inside a computer room by judging whether temperature obtained by simulation is within a specific temperature range or not, and by controlling at least one of wind directions of a fan for covering a position at a temperature that does not exist within the specific temperature range. SOLUTION: Based on temperature, the amount of the wind of a fan, and a wind direction, simulation is carried out, and temperature distribution is obtained. Under the control of a local PC 70, a circuit 76 for controlling the amount of wind controls the speed of a specified fan, and the amount of wind, namely, the force of wind. A circuit 78 for controlling an air conditioner controls the air conditioner according to the state of temperature. For example, when temperature inside a computer room is lower than a specific temperature range, the air conditioner is temporally stopped, or the air conditioner is operated by high power when cooling effect by the fan is low. A circuit 80 for controlling a stator position selectively drives the coil winding of the stator of the specified fan, and controls the wind direction of the fan under the control of the local PC 70.

Abstract: PROBLEM TO BE SOLVED: To make mountable a CPU or an MPU of the highest speed on a portable computer and to improve the performance of the computer by transmit ting the heat of a heat generating body contained in the computer to a carrying tool and discharges the heat of the carrying tool into the air to properly cool the heat generating body. SOLUTION: Heat transfer bodies 22 are placed at the areas corresponding to one or plural heat generating bodies 20 of a portable computer 12 so as to touch these bodies 20 respectively. The transfer body 22 functions to protect each heat generating bodies 20 and also to lower the temperature of the heat generating bodies 20. A window 24 is formed to expose the other side of the transmitter 22 to the outside, so that the heat of the bodies 20 is transferred to the outside through the window 24. Heat absorbers 26 are placed at the positions corresponding to the heat transfer bodies 22 of the computer 12. Each absorber 26 touches each heat transfer body 22 and leads the internal heat of each heat generating bodies 20 to the outside.
