    摘要: A self-starting swinging apparatus including a free-running oscillation circuit comprising two transistors which are a PNP transistor and an NPN transistor, the bases of both transistors being connected respectively to the collector of one transistor directly and to the collector of the other transistor through a capacitor for setting a time constant; a driving coil connected to the collector of the transistor with the capacitor connected thereto, as a load on the transistor; and a permanent magnet having a relatively repulsive magnetic pole arrangement of the same polarity as, or having a relatively attractive magnetic pole arrangement of a different polarity from, that of a magnetic pole in a magnetic field which ought to be generated in the driving coil when an electric current is fed to the driving coil from the oscillation circuit, the permanent magnet being relatively movable with respect to the driving coil and capable of performing a relative swing motion under the action of an arbitrary restoring force, one of the permanent magnet and the driving coil being fixed to a swinging side and the other fixed to a stationary side in a position near or deviated from a neutral point of a swing motion of the swinging side.

    摘要: Permanent magnets (12) are used to perform useful work. The field of a first permanent magnet (12) is diverted by electromagnetic coils (22, 24) to such a low value that another opposing permanent magnet (20, 26, 52) can approach the first magnet (12) withoutthe application of undue force. The field in the first magnet (12) is restored to act on the second magnet so as to repel it. The force which results may be harnessed to effect reciprocal or rotary motion.

    摘要: Acircuitfor controlling the intermittent application of a dc potential to a device, such as a striker mechanism for a gong, having a member reciprocally movable between rest and active positions. The reciprocating member shunts and unshunts a capacitor when the member is in its rest position and moved away therefrom, respectively. While the capacitor is shorted, and during its charge time, dc power is applied to the device. When the capacitor is charged to a predetermined potential, dc power is disconnected from the device thereby allowing the reciprocating member to return to its rest position to shunt the capacitor and initiate a new cycle of operation. The system is substantially independent of mechanical characteristics of the device and the current interrupted or made by the contact pair may be at least an order of magnitude less than the peak current in said device.
