Abstract: A method for manufacturing a hot-dip metal plated steel strip having a plated layer formed on the outer surface thereof includes continuously immersing a steel strip in a bath tub that accommodates a molten metal plating bath, causing a sink roll disposed in the bath tub to change the traveling direction of the steel strip, then causing the steel strip to pass through two support rolls formed of a stabilizing roll and a correcting roll disposed above the sink roll but below the surface of the plating bath, and extracting the steel strip out of the bath. A flow regulation plate is disposed so as to cover at least the upper side of a roll body of the stabilizing roll out of the support rolls with a gap between the flow regulation plate and the stabilizing roll, and the flow of the molten metal plating bath directed toward a portion of the steel strip located from the exit of the support rolls to the surface of the plating bath is led toward the lower side of the stabilizing roll via the gap.

Abstract: A refrigerant compressor includes a compressor housing divided by a valve plate into a first chamber and a second chamber. The valve plate includes suction conduits linking the first chamber with the suction chamber and discharge conduits linking the first chamber with the discharge chamber. A suction valve member bends to open and close the suction conduits in response to changes in discharge chamber pressure and the resulting pressure difference between the first chamber and the suction chamber. A suction valve control mechanism includes a regulator for regulating the opening and closing of the suction conduit between a maximum opening position and a minimum opening position in response to changes in discharge chamber pressure. Consquently, a starting torque shock to the compressor is reduced while maintaining high volumetric efficiency of the compressor.
