Abstract: Provided is a nonaqueous electrolyte secondary battery having improved discharge characteristics. A nonaqueous electrolyte secondary battery according to one aspect of the present disclosure comprises an electrode including a current collector and a mixture layer that is formed on a surface of the current collector and that contains an active material. The current collector includes an electron conductive layer having a gap on the surface in contact with the mixture layer, and an electrolytic solution is present inside the electron conductive layer.

Abstract: A paint supply system includes: a paint supply pump; a paint tank connected to an inlet of the paint supply pump; a paint feed path connected to an outlet of the paint supply pump to feed paint to the coating machine; a paint return path configured to return the paint from the coating machine to the paint tank; and a control apparatus configured to exert feedback control on a discharge amount of the paint supply pump using control parameter values recorded on a table. On the table, the control parameter values are recorded as being classified under a plurality of levels so that the pressure of the paint at a predetermined specified location attains a target pressure more quickly when the pressure of the paint at the specified location is outside a first pressure range including the target pressure than when falling within the first pressure range.
