  • Patent number: 10259032
    Abstract: Metal foil base material placed on lower blade is first restricted under pressure by lower blade and pad and then cut by a shearing action based on an engagement of lower blade side cutting edge and upper blade side cutting edge. Resin face sheets are fixed to the top surface of lower blade and the pressing surface of pad, the face sheets having a larger friction coefficient than that of these surfaces. By frictional forces imparted by face sheets, metal foil base material is prevented from being dragged and moved by the pressing force of the upper blade prior to cutting. Consequently, the occurrence of “burr”, “roll-up”, and so forth is eliminated thereby ensuring a good cutting quality.

  • Publication number: 20130068327
    Abstract: The present invention concerns an electrolyte supplying apparatus including a tank which stores an electrolyte, a supply-receiving unit to which the electrolyte in the tank is supplied, a pipe which connects the tank and the supply-receiving unit, a gas pressure feeding unit which feeds an inert gas under pressure into the tank so that the electrolyte in the tank is supplied to the supply-receiving unit via the pipe by increasing an internal pressure of the tank, and a mass flowmeter which is provided in the pipe and detects a mass flow rate of a fluid flowing in the pipe.
