Abstract: PROBLEM TO BE SOLVED: To reduce the layer number of an electrode current collecting part, easily perform connection to a terminal with high reliability, and improve volumetric efficiency by forming it of a first lead part and a second lead part whose lead parts do not overlap each other. SOLUTION: On the opposed side of a layered body 36 forming an electrode structure body, leads of respective electrodes are respectively layered in two places, and positive electrode lead groups 41a1 and 41a2 and electrode lead groups 41b1 and 41b2 are respectively formed. These lead groups 41a1 and 41a2 , and 41b1 and 41b2 do not overlap each other. Therefore, the number of leads in a position where ultrasonic welding is performed is reduced by half, and welding is also facilitated, and volumetric efficiency increases, and energy density as a battery is improved.

Abstract: PURPOSE:To improve the energy volume density and the weight density, and to lighten and downsize a device by forming one side surface of a cell case, which is formed in parallel with an electrode surface of a layered electrode, into a flexible thin plate. CONSTITUTION:A negative electrode 21b and a positive electrode 21a are arranged alternately so that each lead part thereof is overlapped with each other, and a polyethylene film 21c is interposed between them for lamination, and the periphery thereof is wound with a viscous tape 11 for fixation to form a layered electrode 10. A positive and a negative lead parts 13, 14 are welded to a positive and a negative electrode terminals 5, 6 inside of a barrel part 2. Thereafter, a film 3 made of aluminium foil, which is laminated with polyethylene at a predetermined thickness, is fixed to both side surfaces of the barrel part 2 by the heat seal, and the electrolyte is filled from an electrolyte filing port 8 provided in the upper part of the case 4. Since the side surfaces of the case are thereby formed flexible, a cell is lightened. Plural cells are arranged inside of a battery case and pressurized by a pressurizing spring to form a battery.

Abstract: PURPOSE:To enable printing paper to be easily color-printed by a method where in printing paper, transfer ink paper and a winding shaft winding this transfer ink paper are respectively arranged free rotatably in parallel in a cassette body, and a discharge opening of the printing paper is provided. CONSTITUTION:Since roll form printing paper 30, transfer ink paper 40, and a winding shaft 51 winding said transfer ink paper are built in a cassette body 1, the printing paper and the thermal transfer ink paper can be simultaneously supplied only by installing the cassette body to a printer. Further, since color areas of a plurality of colors are successively repetitively arranged on the transfer ink paper, the printing paper in the cassette body can be color-printed. Further, the color-printed printing paper is discharged from a discharge opening 18 of the cassette body, and the used thermal transfer ink paper is made to be wound on the winking shaft 51. Therefore, after use, the cassette body is taken out from the printer and the thermal transfer ink paper can be easily exchanged.

Abstract: PURPOSE:To ensure that printing paper does not misalign itself with ink paper for transfer by providing a transfer area and a non-transfer area on the ink paper for transfer and allowing the non-transfer area of the ink paper to adhere to the print paper in freely separable manner. CONSTITUTION:Rectangular transfer areas 4a, each being of a single image, with, for example, only black ink applied are continuously provided at an equal interval on an ink ribbon for thermal transfer 4. In addition, non-transfer areas 4b where no ink is applied are provided. Furthermore, the non-transfer areas 4b provided between adjacent transfer areas 4a, 4a on the ink ribbon 4 are put together with printing paper 3 through an adhesive tape 5 which can be peeled off freely. Thus it is possible to prevent the transfer area 4a of the ink ribbon 4 from being misaligned with the printing paper 3 during thermal transfer, as the non-transfer area 4b and the printing paper 3 are placed together by adhesion in freely separable manner.
