It is an object of the present invention to provide a cage that can be used in a cryogenic-temperature environment or a vacuum without providing the cage with a complicated construction and without performing special treatment and a bearing using the cage. The molded article transfer device includes a transfer structure that defines, amongst other things, a first aperture that is structured to receive a first molded article from a first mold stack of the injection mold. The terminal device may include a terminal communication unit, an outputting unit, an input receiving unit and an output control unit. Component models are added or removed from the database or updated as need. The load device may adjust an amount of power in the direct current power signals in order to match the target power level.
