While a charge pump activationdeactivation control circuit is outputting a high level signal, MOS transistors for short-circuiting a flying capacitor are off, and the charge pump circuit operates normally. A servo controller 17 can set the speed of the rod 11 and a load for stopping Ps that is used for determining whether the rod 11 should be stopped so that the load for pressurizing Pm does not significantly exceed the target load Pt. The die assembly consists of a die, an adaptor plate and an ejector plate assembly. Each upright member of the pair of upright members is connected to the leg member and extends downwardly from the leg member to a distal end. Each first contact has a first contact portion protruding into the first receiving cavity and a first tail portion.
