    摘要： A mechanical watch includes a balance, an oscillation circuit configured to output a clock signal, a vibration detection unit configured to detect a vibration of the balance and output a vibration detection signal, a speed governing unit including a permanent magnet and a coil, a speed governing control unit, a storage unit configured to store an electrical energy, and a generator. One of the permanent magnet and the coil is held by the balance. The speed governing control unit compares the clock signal and the vibration detection signal and performs the speed governing control of the balance by exerting an electromagnetic force on the permanent magnet, the electromagnetic force being generated by outputting a current to the coil. When a stored energy amount is equal to or smaller than a predetermined value, the speed governing control unit switches a state to a stop state where the speed governing control of the balance is stopped.

    摘要： A method for orienting a timepiece component including ferromagnetic material, where, on both ends of this component, two magnetic fields each attract it onto a pole piece, with an unbalance in the intensity of these fields around this component, in order to create a differential in the forces thereon and to press one of these ends onto a contact surface of one of the pole pieces, and to hold the other end at a distance from the other pole piece. A magnetic pivot includes such a component with two ends. It includes a guide device with surfaces of two pole pieces each generating a magnetic field attracting one of these ends, the magnetic forces exerted on the two ends being of different intensity, in order to attract only one end into contact with only one of these pole piece surfaces.

    摘要： A mechanical timepiece includes: a hairspring; a permanent magnet; a soft magnetic core; a control circuit for performing rate adjustment based on a counter-electromotive voltage caused in a coil by a motion of the permanent magnet accompanying a forward direction motion and a reverse direction motion of the balance wheel. The permanent magnet is arranged so that, under a state in which the hairspring is brought to an equilibrium length, a direction of magnetization is directed to the first end portion side or the second end portion side.

    摘要： Herein disclosed is an electromagnetic drive circuit for driving a pendulum or the like, comprising: a coil for detecting and driving a permanent magnet; a reference voltage source having a variable reference voltage; a comparator for generating an output when the induced voltage of the coil exceeds the reference voltage; a pulse generator for generating a drive pulse in response to generation of the output of the comparator; a driver responsive to the drive pulse for feeding a drive current to the coil; and a controller responsive to the output of the comparator for controlling the reference voltage in accordance with the amplitude of the induced voltage. It is possible to integrate the most of construction and to eliminate the disadvantage of generating the drive pulses at the level of the induced voltage other than its maximal point so that the automatic control can be accomplished to effect the drive efficiently at the maximal point of the induced voltage at all times. Thus, the permanent magnet can be driven efficiently with the stable amplitude.
