摘要： PROBLEM TO BE SOLVED: To prevent neck-in of a melt resin film extruded from T-dies when the resin film is coated on a metal plate by disposing between the T-dies and coater rollers two pairs of blowing means for blowing high-pressurized air to both the ends of the melt resin film extruded from the T-dies. SOLUTION: Nozzle 5, 5' for blowing right and left two pairs of air stream are provided directly under T-dies 2. Blowing high-pressurized air to both edges 3a of the melt resin film 3 prevents the width of the resin film 3 from contracting. The resin film 3 of the part where the high-pressurized air is not blown of the nozzle 5 is sandwiched along with a metal plate 1 by coater roller 4, 4' provided so as to have a rotational axis parallel in the lower surface of the T-dies 2 directly under the nozzle 5, thereby forming a resin coating metal plate 6 having a part 7 comprising only integrally overlapped resin films blown with the high-pressurized air by the nozzle 5 forced out of the metal plate 1 at both the sides. Thus neck-in of the melt resin film in prevented.

摘要： PROBLEM TO BE SOLVED: To provide a battery whose discharge characteristic is not deteriorated for a long period of time without fusing-out of plating layer constituent into an alkaline solution by forming an alloy layer of nickel-indium by electrolytic plating, and using a steel plate where the nickel-indium alloy layer has formed as well as a steel plate of a case material where a diffusion layer is formed in an inner surface of the battery case. SOLUTION: In forming a nickel-indium alloy plating layer, there are several methods, i.e., a method of applying nickel plating as strike plating at first, and applying indium plating thereafter; a method of applying nickel plating at first, and applying nickel-indium alloy plating thereon; and a method of applying nickel-indium alloy plating without application of strike plating. After nickel-indium alloy layer is formed on a steel plate, it is heated at 300-65 deg.C for 240-600 min. under the atmosphere of inactive or nonoxidization gas to thereby form an iron-nickel-indium diffusion layer on a boundary surface of steel plate.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of the deterioration of tension stress or excessive tension in a flying plate thickness changing process, and to realize stable and efficient continuous rolling in the arbitrary combination of preceding material and succeeding material. SOLUTION: When setting each pass schedule of the preceding material and the succeeding material by a pass schedule setting means 30, an intermediate pass schedule is determined by a pass schedule calculating means 31. The roll opening degree setting value, roll speed setting value and tension setting value between stands of each stand of the tandem rolling mill in each process of a first flying plate thickness changing from the pass schedule of the preceding material to an intermediate pass schedule and a second flying plate thickness changing from the intermediate pass schedule to the pass schedule of the succeeding material, are determined previously by a setting value calculating means 32. On the other hand, first plate thickness changing point position and second plate thickness changing point position, are determined by a plate thickness changing point position determining means 33, and the positions of two plate thickness changing points, are detected by a setting value output means 34. At timing when the plate thickness changing point has reached each stand, the roll opening degree setting value, roll speed setting value and tension setting value between stands of a corresponding rolling mill, are changed by using the output of the setting value calculating means.

摘要： PROBLEM TO BE SOLVED: To continuously laminate resin having a print pattern on a strip-like metal plate with satisfactory dimensional accuracy by transferring a resin layer to the plate while continuously bringing a striplike carrier obtained by laminating the resin layer into close contact with one surface at least on one surface of heated striplike metal plate. SOLUTION: A striplike metal plate 20 rewound from a metal plate rewinding means Rc is heated by a heating means 2. Meanwhile, a striplike resin laminate carrier 21 formed of a carrier 25 and resin layer 22 is rewound from a carrier rewinding means 3. A resin layer 22 is brought into contact with the heated plate 20 via a deflector roll 5, sandwiched between laminate rolls 4, and laminated. This plate 20 is fed to a separating roll 8 to separate only the carrier 25, and wound by a carrier winding means 9, and the resin-coated metal plate laminates only with the separated layer 22 is wound by a winding means 10. As a result, the optimum resin layer is laminated with satisfactory dimensional accuracy.
