Abstract:
PROBLEM TO BE SOLVED: To provide a configuration and a method to raise cooling capability of a portable personal computer. SOLUTION: By this method, cooling capability of a lap-top computer whose size, weight, and power consumption are restricted can be improved by conducting and radiating heat to the rear of a liquid crystal display of the lap-top computer from the semiconductor chip which is located in the computer and must be cooled .

Abstract:
PURPOSE: To provide a portable PC excellent in operability and durability while reducing its weight and thickness by making it possible to lift a pointing device of the PC. CONSTITUTION: This portable PC and keyboard system has a mechanism, for lifting the pointing device 30. A lifting mechanism can be constituted so as to lift the device 30 based upon the position of a cover for the computer. A base part 104 fixes the device 30. The base part 104 is connected to the pallet part 26 of the keyboard by hinge 106. The base part 104 is pushed up by the movement of an arm 110 interlocking with the open/close of the cover. Thereby the device 30 fixed on the base part 104 is pushed up to a position higher than an adjacent key 28.

PROBLEM TO BE SOLVED: To provide an antenna structure for antenna used for an electronic apparatus, capable of implementing calibration of frequency shifting for the antenna after the last assembly of the electronic apparatus. SOLUTION: An antenna structure 10 installed at an electronic apparatus comprises a radiating element 11 for receiving/radiating electric waves, a ground (GND) 12 arranged with a predetermined gap for the radiating element 11, a frequency shifting dielectric 20 arranged close to or contact with the radiating element 11 and capable of being moved at least a part of it after radiating element 11 is mounted at the electronic apparatus, and a calibration screw 21 for attaching the frequency shifting dielectric 20 to the ground 12. The frequency shifting dielectric 20 is turned by rotating the calibration screw 21 to adjust a distance between the radiating element 11 and the frequency shifting dielectric 20. Consequently, the center of frequencies can be aligned. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To improve the heat transferring performance by promoting the circulation of the liquid-phase working fluid in a heat pipe comprising a porous wick. SOLUTION: In this heat pipe, the condensable working fluid is sealed inside of a container sealed in an airtight state, the wick 5 composed of a porous material is mounted inside of the container for circulating the liquid-phase working fluid by capillary pressure, a part of the container 2 is used as an evaporating part 3 for evaporating the working fluid by the heat from the external, and the other part of the container is used as a condensing part 4 for condensing the working fluid by radiating the heat to the external. A direct-current circulating passage 6 having a cross-sectional area larger than a cross-sectional area of a pore formed on the porous material 5 and allowing the liquid-phase working fluid to flow toward the evaporating part 3, is formed.

Abstract:
The keyboard assembly for a computer with movable keyboard pallets. The pallets are movable relative to each other between a compact stowing position and an extended operational position. A movement mechanism moves at least one of the pallets in a lateral direction relative to the other pallet and then towards the other pallet in a direction orthogonal to the lateral direction. The movement mechanism can be connected to the cover of the computer to automatically control movement of the pallets based upon position of the cover relative to a base of the computer. Thus, the pallets can be automatically moved from the compact stowing position, when the cover is closed, to the extended operational position when the cover is opened. Upon moving the cover from the open position to the closed position, the pallets are automatically moved from the extended operational position to the compact stowing position.
