METHOD AND APPARATUS FOR SYNCHRONISING AN OSCILLATING SYSTEM PARTICULARLY A TIMEPIECE, WHICH IS EN BY AN ENERGY STORAGE MEANS |
摘要 |
<p>A technique of synchronizing an oscillating system driven by a mechanical energy storage means, particularly a timepiece having a regulating member which is set and maintained in oscillation by a pulse-like driving moment and which is synchronized by electromechanical action by means of timing pulses derived by division from a quartz oscillation, characterised in that the synchronizing action is achieved through an electromagnetic coupling or electromotively through indirect synchronization, in which a phase and frequency comparison is made between said timing pulses and an alternating voltage signal derived from the movement of the oscillating system, for example of the balance, with the oscillating system of corresponding frequency and phase, while in addition a regulating signal is derived from the comparison and is utilized to produce a torque MR which through the electromagnetic coupling applies a regulating action to the oscillating system.</p> |
