Abstract: PROBLEM TO BE SOLVED: To make it possible to form an extremely thin coating on a glass substrate by a die coater. SOLUTION: This application apparatus comprises a coating liquid supply means for supplying a coating liquid, a coater 40 having a discharge outlet for discharging the coating liquid supplied from the coating liquid supply means to an object member to be coated, and a moving means for relatively moving at least one of the coater 40 and the object member to be coated A to form a coating film on the object member to be coated A. In the application apparatus, the coater 40 is installed in a coater installation means which is made freely movable in the gravity direction by the external force applied to the coater 40 from the discharged coating liquid at the time of application.

Abstract: PROBLEM TO BE SOLVED: To form coating film ends to a prescribed coating film thickness profile within a predetermined short range by executing coating film formation several times to form the prescribed coating film thickness profile when forming the coating films on a member to be coated by relatively moving at least either of a coating applicator and the member to be coated. SOLUTION: A table 6 on which the member A to be coated is placed is moved to locate the coating start part of the member A to be coated to the discharge port of a die. On the other hand, the coating liquids sucked from respective tanks 50A, 50B are fed into the die by respective syringe pumps 44A, 44B. A start signal is outputted from a computer 54 to a sequencer 56 after lapse of the prescribed time and the coating is started by moving the table 6 at a prescribed speed. The coating is ended when the coating end part of the member A to be coated exists at the discharge port of the die. At this time, the respective coating start positions and end position, respective coating weights and characteristics of the respective coating liquids 76A, 76B are merely necessitated to be optimized in order to control the film thickness profile.

Abstract: PROBLEM TO BE SOLVED: To make it difficult to generate the internal short circuit, and to prevent rupture and ignition of a battery when a nail, etc., is pierced in a battery can of the battery in the charged condition by providing a rubber material which is high in elasticity and shows the electric insulation at least on a part of a separate substance and/or an electrode body. SOLUTION: A negative electrode, a positive electrode and a spiral electrode body 14 around which the separate substance is wound, are stored in a battery can. A rubber material which is high in elasticity, i.e., >=3kg/cm in tensile strength and >=10kg/cm in breaking strength, and shown the electric insulation, is provided on the outer circumference of the separate substance and/or the spiral electrode body 14. Even when a projection is pierced from the outside of the battery can, contact of the positive electrode with the negative electrode is prevented by the elasticity of the rubber when the rubber material is provided on the separate substance. When the sheet-like latex rubber 15 of the rubber material is provided on the outer circumference of the spiral electrode body 14, the rubber is entangled around the projection to prevent the contact with the positive electrode with the negative electrode, and the electrode reaction by the internal short circuit can be prevented.
