Abstract
A technique is provided for oscillation maintenance in mechanical resonators of the type actuated by electric pulses transmitted by a coil to a permanent magnet carried by the resonator or conversely, the oscillation frequency of the resonator being modified by the action of a spring repelling it elastically on both sides of its resting position. Starting from a train of chopped (contact-modulated) square-wave pulses varying according to a tempo corresponding to a pilot frequency f in such manner that, for each succeeding alternation of this latter, the pulses are divided so as to correspond alternatively to one of two energies of different levels. The voltages induced by the resonator magnet in the induction coil is compared to the aforesaid pulse train and so acts that each successive alternation of a given signal of said voltage, beyond a preset threshold, triggers the transmission to the induction coil of a maintenance energy of the value contained in the equivalent section of the pulse train. The purpose is to establish a state of synchronism between the pilot frequency f and that of the mechanical oscillation.
