Abstract: A portable phone including a connecting member such as a hinge part for coupling a display housing and a grip housing in a manner that a first state in which the display housing and the grip housing are folded together, and a second state in which the display housing and the grip housing are coupled at one end, are exchangeable. The display housing includes a display unit, a fuel cell, and a fuel cartridge, and the grip housing includes an operation part and a rechargeable part for storing electricity generated by the fuel cell, the fuel cartridge is detachably mounted on the side face of the display housing.

Abstract: There is provided a power generator including a plurality of power generation elements, and a fuel supply portion that communicates with the plurality of power generation elements through a fuel supply passage, the plurality of power generation elements are housed in a plurality of independent power generation casings having vent portions, and the plurality of power generation casings are movably connected via a connecting portion so as to enter a housing state where the casings are placed on top of each other and a power generation state where the casings are separated. There is provided a portable power generator that can ensure sufficient ventilation and power generation areas in use (during power generation), and becomes compact when carried.

Abstract: A portable information terminal unit comprises a first and a second casing, a hinge means for coupling the first and second casing so that the first and second casing are rotatable relative to each other, an opening piercing though the first casing, a first see-thorough liquid crystal display part fitted in the opening, a means for detecting opening of the first and second casing, relative to each other, and a control means for reversing a display on the first see-through liquid crystal display part in response to a detection by the detecting means, wherein monochromatic information is displayed on the first see-through liquid crystal display part so as to reduce power consumption.

Abstract: An information communication terminal device having a first display/operation part and a second display/operation part mounted on an upper and a lower case, respectively. A housing member accommodates a video camera therein, and a support mechanism rotatably supports the first display/operation part, the second display/operation part and the housing member on the same rotation axis with respect to each other. The first and second display/operation parts are rotatably mounted by at least 180 degrees about the housing member and are structured so as to be opposed to each other when the information communication terminal device is in an opened condition and to be overlapped with respect to each other when the information communication terminal device is in a closed condition.
