Abstract: PROBLEM TO BE SOLVED: To improve heating efficiency and enable heating of low resistance and a low magnetic permeation rate of aluminum or the like by constituting a heating coil element wire diameter by a litz wire of a specific diameter and molding it and generating a high-frequency magnetic field by a specific high-frequency current. SOLUTION: To heat a non-magnetic body or an aluminum pot with small resistance in a similar way as an iron pot, it is necessary to increase an input resistance to 20 times. Therefore, a heater coil winding has more turns than 20T for the iron pot, and an inverter frequency is increased. At this time, the inverter frequency is set to 40kHz or more, a heater coil is constituted by the litz wire of 0.2mm or less in heater coil element wire diameter to increase the input resistance, thereby ensure improvement in cooling capacity. A heating coil 2 is constituted by 119 stranded litz wire 1 of 0.2mm in element wire diameter and molded by a mold material 3. The mold material 3 is intruded to the inside of the heating coil 2, thermal conductivity is improved, and cooling capacity is improved.

CONSTITUTION: In the case of the communication from a terminal A which is a telephone set to the terminal B which is a personal computer, the signals from the terminal A are transmitted through the normal telephone line 1 to the communication base station 2 first. In the communication base station 2, after recording the signals from the terminal A, voice signals are converted to character/picture signals, the computer network 3 is accessed and the signals are transmitted to the terminal B. Also, inversely, when the communication from the terminal B to the terminal A is considered, the signals from the terminal B are transmitted through the computer network 3 to the communication base station 2, converted from the character/picture signals to the voice signals and then, transmitted through the telephone line 1 to the terminal A.

Abstract: PURPOSE:To make it possible to connect reliably heating units to a heat dissipation means regardless of the sizes and inclination of the heating units by a method wherein with particles having a heat conductivity encapsulated between the heating units and the heat dissipation means, one part of an enclosure is formed into a flexible structure. CONSTITUTION:A heat sink 25 of a semiconductor package 15 is constituted of an insulating film 17, whose one part is flexible, and metallic particles 21, whose diameters are different from each other, and a heat transfer fluid 23 is filled in spaces 19 between the particles 21 between the film 17 and a cap 9. Heats of chips 1 are transferred to the particles 21 via the film 17 and after being transferred to the fellow particles 21, the heats are emitted to the outside through heat dissipation fins 11 via the cap 9. In this constitution, as one part of the film 17 is flexible, while an irregularity in the heights of the chips 1 above a substrate 3 and the inclination of the chips 1 are absorbed, the sink 25 can reliably come into contact to the back surfaces of the chips 1 and the heats of the chips 1 can be efficiently transferred to the sink 25.
