Abstract

PURPOSE:To hold the moving position of a permanent magnet of DC solenoid at a transferring position by magnetic force of the permanent magnet by a method wherein the permanent magnet is fixed to a movable body, the permanent magnet is enabled reciprocating transference between the cores of excitors, and transference of the movable body is made to be performed smoothly by repelling action from one side and by absorbing action from another side. CONSTITUTION:The two excitors 1, 2 consisting of coils 5, 6 and the cores 3, 4 are provided in a case 7 facing with each other and interposing an interval between them. The movable body 10 consisting of a non-magnetic material is arranged in a penetrating hole 8 provided at the center part of the cores 3, 4. The permanent magnet 9 is fixed to the movable body 10, and is positioned being enabled to transfer reciprocally between the cores 3, 4. By constituting the device by this way, and when electromagnetic force is generated as to make the insides of both the excitors 1, 2 become to the same polarity, anode N for example, repelling action is generated between the anode N of the permanent magnet 9, or absorbing action is generated between the cathode S of the permanent 9, the permanent magnet 9 is transferred to the excitor 1 side together with the movable body 10 to be absorbed to the core 3, and even after the excitors 1, 2 are demagnetized, it holds the transferred position to the core 3 side by magnetic force of the permanent magnet 9.
