摘要： PROBLEM TO BE SOLVED: To manufacture a handrail by keeping handrail property stable at all times and simplify the manufacturing process by the use of a thermoplastic elastomer by a method wherein a decorative rubber layer is provided on an outer layer except the lower end part side of a core body formed by filling a rubber layer in a tubular body, which is prepared by forming a thick woven fabric into a tubular shape with a C-like sedtion. SOLUTION: A tension body is arranged near at the center of a tubular body 1, which is made of a thick woven fabric 1a into a tube. Next, by continuously adhering a certain fixed amount of rubber to the inside of the tubular body 1, a rubber layer 2 is formed. Next, during the period that the fluidity of an extruded rubber is kept, by shaping the section of the rubber into a C-shaped form, a core body A is produced. In this case, it is important that no gap is left in the rubber layer 2 within the core body. Next, a decorative rubber 3 covers the outside of the core body A. As the covering method of the decorative rubber 3, a method for fixing by pressure with a press, a coveringly fixing method by pressure with an extrusion molder or the like is employed. In order to continuously manufacture a handrail, the employment of a thermoplastic elastomer is preferable.

摘要： PROBLEM TO BE SOLVED: To provide a molding method for a positive electrode mix wherein no chipping is produced and no dust is generated when the positive electrode mixes for an alkaline dry battery, made in such a manner that a plurality of molded positive electrode mixes are press-fitted into a positive electrode can, are forced into the positive electrode can, and moreover, after press-fitting, they contact closely an inner wall of the positive electrode can and can be packed into the positive electrode can with high density. SOLUTION: In this method, a positive electrode mix 1 is manufactured such that a material for the positive electrode mix is put in a metal mold 10 and compressed. The metal mold 10 is formed to have an inverse tapered part 10a gradually expanding as it goes up from its inside middle part while an upper part of the tapered part 10a is formed into a straight part 10b somewhat larger than the inner diameter of a positive electrode can 2 of an alkaline dry battery, and the material for the positive electrode mix is thereby adapted to be pushed upward and take out after it is put in the metal mold 10 and compressed.

摘要： PURPOSE:To provide a battery fitted with a safety mechanism which has a vent mechanism easy to adjust the vent pressure operating stably with a low pressure not leading to rupture of the battery even though a gas generation therein has boosted the battery internal pressure. CONSTITUTION:A battery case 1 is provided with a hole 3, whose edge projects to the outer side, to exhaust gas from the battery. A hot-bond, type resin of polyolefin type 4 is applied on the outside of the hole 3 in such a way as enclosing the projection and blocking the hole 3, and thereby the battery case 1 is sealed. Therein the angle theta and dimension (h) of the projection at the edge of the hole 3 are changed to adjust the actuation pressure of the safety mechanism.

摘要： PURPOSE:To ensure operation at the time of rising in the internal pressure, by providing a level difference portion, which is directed upwards, at the peripheral portion of an upper lid, and making the gap between the boundary portion formed by the upper surface of the level difference portion and that formed by the lower surface of the level difference portion smaller than the thickness of the upper lid material. CONSTITUTION:A level difference 1a is upwardly provided at the peripheral portion of an upper lid 1, an accumulator casing 2 is fitted in the under side of the level difference portion 1a, and a welding portion 100 is formed from side by means of a laser solvent to provide a hermetical sealing. At this time, the level difference portion 1a is formed by pressing, and the dimension of the gap between the boundary portion of the upper surface of the level difference portion and that of the lower surface of the level difference portion can arbitrarily be set through adjustment of the mold at the time of pressing. When the dimension is made smaller than the thickness of the material of the upper lid 1, a rapid increase in the internal pressure causes the thin-walled portion to be cracked and opened, whereby exhaust is effected. Thus, even if the internal pressure is rapidly increased, the operation is surely carried out to prevent the bursting.

摘要： PURPOSE:To prevent a battery from being fired or broken in the event of internal shortcircuits and minimize the damage of the battery by stacking a metallic film and a positive electrode- active material on the plastic film of a positive electrode plate, and also providing a fuse portion at one part of the metallic film. CONSTITUTION:A positive electrode plate 3 is fabricated by depositing a metal film 3b on the base of a plastic film 3a having a notched portion 3f, then removing one part of the metallic film 3b by means of patterning, forming a current collecting portion 3c and a fuse portion 3d, and applying a rechargeable positive electrode active material 3e onto the metallic film 3b. During discharge lithium is ionized and dissolved from a negative electrode plate 4 into an electrolyte with which a separator 5 is impregnated, and combines with the positive electrode active material 3e of the positive electrode plate 3; during charging the positive electrode active material 3e is dissociated from the lithium and the lithium is released as lithium ions into the electrolyte and deposited on the negative electrode plate 4 and the process of charging and discharging the battery is repeated. Even if the internal shortcircuit between the positive electrode plate 3 and the negative electrode plate 4 occurs as the lithium deposited on the negative electrode plate 4 takes the form of dendrites (trees) and breaks through the separator 5, the fuse portion 3b provided to the positive electrode plate is welded by excess current caused by the short-circuit current, so preventing subsequent current flow from other positive and negative electrode plates.

摘要： PURPOSE:To reduce the cost of parts, to make the production system at a low cost, and to improve safety, by putting in an insulating washer to an anode terminal plate which has a reverse taper. CONSTITUTION:An anode terminal plate 1 and an outer can-cum-cathode terminal 9 are calked through a gasket 4. In this case, a punched plate-form insulating protective washer 2 made of a resin is inbedded to the anode terminal plate 1 which has a reverse taper making as 1a>1b. And a mounting tube 10 is used to cover the side surface of an outer cam 9, the periphery of the cathode terminal 9a, and the insulating protective washer 2 from the outer side by a thermal contraction, to finish the mounting. By such a constitution, no terminal tip at the apparatus side is put in between the anode terminal plate 1 and the outer can 9. And the forms of parts and the production system are simplified.

摘要： PURPOSE:To extend the charge/discharge cycle life by forming a metal deposition film on one or both faces of a plastic substrate, and providing a positive electrode plate coated with a positive electrode active material on it and a negative electrode pressed with a negative electrode active material mainly made of lithium on the similar metal deposition film. CONSTITUTION:A positive electrode active material 3 is coated on a metal deposition film 2 formed on a plastic substrate 1 to form a positive electrode plate. The positive electrode plate is spirally wound and stored in a negative electrode can together with a spacer 5 and a negative electrode plate made of a negative electrode active material 6 via a separator 4. Extremely thin lithium or its alloy is pressed to the film 2 formed on the substrate 1 to form the negative electrode plate. A long charge/discharge cycle life and high performance are obtained.
