Abstract: To provide a method of manufacturing a battery capable of providing an equal amount of electrolyte in each battery and of enhancing productivity and coating machines employed thereof. The sensor detects a boundary from the collector exposed region C of the belt-shaped positive electrode to the positive electrode mixture layer exposed region B, on the basis of the detection timing, the shutter is withdrawn to open the flowing path and the proportioning pomp is driven. Following this, when the sensor detected a boundary from the positive electrode mixture layer exposed region B to a collector exposed region C, and on the basis of the detection timing, the shutter is protruded inside the flowing path to close the flowing path and the proportioning pump stops. As a result of this, the electrolyte stops to be delivered from the nozzle. The electrolyte layers are intermittently formed by repeating the same procedures.

Abstract: The present invention relates to an apparatus as well as systems and methods for masking ceiling or wall fixtures, such as recessed light fixtures, during residential and commercial painting and drywalling. Through the use of an insert mask, a user can quickly and safely mask a fixture without the use of special tools or ladders. Typically, the user positions the insert within a defined opening on the ceiling or wall fixture. The insert is fully inserted into the opening whereby a retaining surface on the insert creates a friction fit between the fixture and the insert. While the insert frictionally resides within the opening, any overspray or misapplication of painting or drywalling material is captured by a protective surface of the insert. Following the material application process, the insert can be removed from the fixture. In an embodiment, the insert mask system includes an insertion tool for insertion and removal of the insert from the fixture.
