摘要： PURPOSE:To start a pendulum without putting a hand directly thereon by a method wherein magnetic lines of force are generated in an electromagnetic coil and the magnetic imbalance of attraction or repulsion is generated successively by the mutual actions of said magnetic line of force and the pendulum M. CONSTITUTION:When a switch S is closed, a current of about 9muA flows to a diode 2 through a resistor 3 to cause a bias, and thereby a current is made to flow to a coil M. Then an electromotive force is generated in a coil S and thereby a current is made to flow to the base of a transistor (Tr) 5 through a diode 1. The transistor is thereby set completely in the state of operation. The balanced relationships of a pendulum M to the core of an electromagnetic coil and an iron piece which are disposed in somewhat deviation from the center line of the pendulum M are lost by a weak oscillation current of the electromagnetic coil, and thereby the pendulum M is moved slightly. Then an electromotive force in a forward or backward bias is generated in the transistor on the coil S, and thus an oscillation frequency changes slightly. This change acts in the direction wherein the movement of the pendulum M is further increased, and thus the pendulum M is moved increasingly.
