Abstract: PROBLEM TO BE SOLVED: To move piping connecting an applicator with a coating liquid supply means simultaneously, to move the piping smoothly and surely, to prevent the deterioration of application accuracy due to the deformation of the piping, and to obtain a high quality plasma display in high productivity by moving the applicator and the supply means simultaneously. SOLUTION: A die coater has a mounting table fixed to a base 201, a gate- shaped frame 202 for holding a die 40 through a vertically moving mechanism, a linear bearing 204 for guiding the frame 202 along a rail 206 on the base 201, and others. The extension/contraction of a linear actuator 238 is adjusted to made the discharge opening face 74 of the die 40 parallel to the suction face of a fixed mounting table. After that, a suction valve 243 is closed, a discharge valve 244 is opened, and a coating liquid is supplied from a quantitative pump 242 to the die 40 to apply the liquid on a substrate on the suction face. In this process, a coating liquid supply unit 240 is moved simultaneously with the die 40 so that the frame 202 can move without being hindered by each piping 248, 249.

Abstract: PROBLEM TO BE SOLVED: To obtain a uniform thickness of a coating film by preventing the increase in film thickness in the end parts by reducing a discharge, to provide a means which has flexibility to maintain application uniformity always even when the kind of a coating solution is changed and is high in reproducibility, and to materialize uniformity even at a high speed without generating film cutting even when an application speed is increased. SOLUTION: In an applicator, a discharge opening for discharging a coating solution is constituted by inserting a shim 102 of a prescribed thickness into the inside, and the shim 102 has a shape which changes the shape of a coating solution passage over the longitudinal direction of the discharge opening and/or the discharge direction of the coating solution so that the distribution of the discharged coating solution changes over the longitudinal direction of the discharge opening.

Abstract: PROBLEM TO BE SOLVED: To provide an electrode for a battery excellent in safety, and provide a secondary battery using this electrode by laminating a resin layer on at least one part of an electrode material layer, which contains the active material. SOLUTION: An electrode for battery is formed by providing an electrode material layer, which contains an active material, on one surface or both surfaces of a collector. It is necessary for safety to laminate a resin layer on a part or the whole of the electrode material layer. As a resin, any resin, for example polyvinylidene fluoride, can be used. As a method for laminating the resin layer, any method for coating the electrode material layer with a resin solution and for drying it can be used. In this case, the electrode material and the resin layer are desirably adhered to each other so as to secure the higher safety. With this structure, even in the case where it is stung by a nail, the electrode material layer and the controller are hard to be exposed, and since the sudden generation of internal short-circuit between the electrode material layer or the collector and a battery can through the nail is hard to be generated, the safety is further improved.

Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of an internal short-circuit when a battery is manufactured and used by setting the distance of one opposite portion between a positive electrode and a negative electrode in the partial range longer than that of the other opposite portion in the battery having a spirally wound electrode body. SOLUTION: In a battery having a spiral electrode body 3 spirally wound with a positive electrode and a negative electrode via a separator, the distance of one opposite portion between the positive electrode and the negative electrode in the partial range is set longer than that of the other opposite portion, preferably to three times the distance of the other opposite portion. The partial range is selected to the range within 10cm from the winding starts of the opposite portions of the positive electrode and the negative electrode for the manifestation of the characteristic near the core where an internal short circuit easily occurs. A separator is laminated at the internal short circuit occurrence position when the electrode body 3 is wound, the distance of the opposite portion between the positive electrode and the negative electrode is extended, and the position can be repaired.

Abstract: PROBLEM TO BE SOLVED: To provide a high-capacity battery which has good cyclic characteristics and ensures a high safety by winding a positive electrode sheet and a negative electrode sheet spirally to accomplish an electrode body, and using a negative electrode active material having a greater charging capacity than the positive electrode active material. SOLUTION: An electrode body is formed by winding round a positive electrode sheet and a negative electrode sheet spirally, while lithium salt is used as electrolyte. In this battery, the negative electrode active material is given a charging capacity per unit weight as 3.0 times greater than the positive electrode active material. The positive electrode sheet should favorably be structured so that the active material quantity on the outside surface is 0.97-1.03 times per unit area of electricity collector as large as the active material quantity on the inside surface. It is also preferable that the active material quantity per unit area of electricity collector on the outside surface of the negative electrode sheet is greater than on the corresponding inside surface and that the ratio of coating amount ranges between 1.03 and 1.20. Further the material of the positive electrode should preferably contain transition metal compound(s), while the material of negative electrode should preferably contain an amorphous carbonaceous material and also carbon fibers.

Abstract: PROBLEM TO BE SOLVED: To manufacture a battery with high filling ratio and high battery capacity by increasing the application quantity of a positive electrode material and a negative electrode material within a specified range. SOLUTION: When the application quantity of an electrode material is increased, the charge and discharge capacity of a battery is increased because the substantial charging quantity is increased. With an application thickness less than 250μm, the filling ratio is largely reduced by the reduction in application thickness, and in order to provide a higher filling ratio, thus, the application thickness must be set to 250μm or more. When the application thickness is larger than 400μm, the probability of cracking in winding is increased. Thus, in both a positive electrode sheet and a negative electrode sheet which are spirally wound, the total application thickness in both the sheets is set to 250μm or more and 400μm or less, whereby a battery with high filling ratio and high battery capacity can be manufactured.

Abstract: PURPOSE:To obtain a composite membrane for separating gas excellent in both gas permeability and selectivity by allowing organopolysiloxane having silanol group in a side chain to react with a silane or siloxane crosslinking agent on a supporting membrane. CONSTITUTION:The following polymer shown in a formula is used which has silanol group in an end group of one part of a side chain of polyorganosiloxane having a repeated unit bonded with siloxane in a principal chain. This polysiloxane is allowed to react with a silane crosslinking agent or a siloxane crosslinking agent on a fine porous supporting membrane. As the silane crosslinking agent, acetoxysilane, oxime silane and alkoxysilane, etc., are high in reactivity and therefore preferably used. The siloxane crosslinking agent is a hydrolyzed condensate of these silane crosslinking agents. Polysiloxane coated on the fine porous membrane is preferably regulated to 0.01-5wt%, and the crosslinking agent is regulated to 2-100 times equivalent of the number of silanol group.
