Abstract: An improvement has been made in contact states between a rotating electrode arranged inside a vacuum chamber and a power supply mechanism which touches the rotating electrode to supply electric power thereto. A vacuum device is provided with a vacuum chamber, a rotating electrode arranged inside and electrically insulated from the vacuum chamber, and a power supply mechanism which touches the rotating electrode to supply electric power thereto, wherein the rotating electrode has an annular shape and horizontally rotates with respect to the center axis of the annular shape, and the power supply mechanism is composed of electrode members, and the electrode member and the rotating electrode come into contact with each other at at least one contact surface.

Abstract: A press for adjusting and inspecting molds is disclosed, which comprises a vertically movable slide and two bolsters provided on the lowermost position of the opposite sides of the slide. The slide has a coupler provided on either side. Each bolster has a coupler provided on either end. The couplers of each bolster can be coupled to the respective couplers of the slide by first coupling one of them to the corresponding coupler of the slide such that the bolster can be swung relative thereto. The slide includes a bolster inverter, which consists of a piston-cylinder assembly or the like for swinging a bolster about its end detachably coupled thereto, and an inverter orientation controller for turning the end of the bolster inverter toward the respective bolsters. Two molds are disposed on the opposite sides of the lowermost position of the slide, and either one of them can be adjusted and inspected when desired.
