However, in this state, the current flowing through the winding 7 is reversed to flow the current through the electromagnet winding 7 so that the spring material 6 side becomes the N pole. , D pistons 2 descend, and pistons B and C rise. Then, when the pistons 2 (a) and (2) are located at the lowest end, and the pistons (b) and (c) are located at the highest end, the flow of the current flowing through the winding 7 is reversed again to cause the winding 7 of the electromagnet to spring. Current is passed so that the material 6 side becomes the south pole.
