    摘要: The present invention provides an air path forming plate used for heat exchangers having an intake air path between an outdoor intake port for capturing outdoor air and an indoor flow-in port and having an exhaust air path between an indoor intake port for capturing indoor air and an outdoor exhaust port. Each of the intake air path and the exhaust air path is made of a metal plate having a bend section on which press marks aligned like a perforation line are formed.

    摘要: A die cushion apparatus of a press machine in which a discharge opening of a fluid hydraulic pump/motor is directly connected to a pressure chamber on a cushion pressure production side of a fluid hydraulic cylinder and the torque of a rotating shaft of the fluid hydraulic pump/motor is controlled by an electric motor to control a pressure (die cushion pressure) of the pressure chamber on the cushion pressure production side. It is therefore possible to control the die cushion pressure with excellent responsiveness with respect to a die cushion pressure command and prevent occurrence of a surge pressure. The die cushion apparatus also has excellent energy efficiency since energy required for a die cushioning action that a cushion pad receives when effecting die cushioning of a press machine is regenerated as electrical energy through the fluid hydraulic cylinder, fluid hydraulic pump/motor, and electric motor.
