摘要： This invention relates to an electromechanical oscillator for time measurement, wherein the oscillation of a mechanical resonator is sustained through a coil coupled with the resonator, the coil being connected in one branch of a feedback bridge circuit connected between the input and output of an amplifier. In order to avoid a compensating inductance for said coil a specific network of resistors and condensers is provided including a compensating resistance for the ohmic component of the coil impedance and a supplemental resistance for compensation of the inductive component of the coil impedance.

摘要： A constant frequency electromagnetic driving device, for example for a time piece, comprises an electromechanical transducer having a coil electromagnetically coupled to a movable mechanical element and serving both pickup and driving functions to convert mechanical movement of the movable element into an electrical signal and also to convert an electrical signal into mechanical movement of the moving element. An electric circuit shifts the phase of the electrical signal generated by movement of the moving element, amplifies the phase-shifted signal and feeds it back to the coil to drive the moving element.

摘要： A MINIATURE TIMEPIECE DRIVEN BY A TUNING-FORK MOTOR WHOSE VIBRATORY ACTION IS ELECTROMAGNETICALLY SUSTAINED BY AN ELECTRONIC DRIVE CIRCUIT. TO REGULATE THE TIMING RATE OF THE MOTOR, A FREQUENCY STANDARD IS PROVIDED IN THE FORM OF A CRYSTAL OSCILLATOR WHOSE FREQUENCY IS AN EXACT MULTIPLE OF THE PRESCRIBED TIMING FREQUENCY OF THE MOTOR. THE MOTOR IS PRESET TO OPERATE AT A TIMING RATE DISPLACED TO ONE SIDE OF THE PRESCRIBED FREQUENCY TO A DEGREE DETERMINED BY THE MAXIMUM ANTICIPATED DEVIATION IN TIMING RATE CHARACTERISTIC OF THE MOTOR. TO EFFECT REGULATION, PULSES ARE DERIVED FROM THE ELECTRONIC CIRCUIT, THE PULSES HAVING A PERIODICALLY EQUAL TO THE OPERATING FREQUENCY OF THE FORK. THESE PULSE ARE COMPARED IN A COINCIDENCE CIRCUIT WITH THE STANDARD OSCILLATIONS TO PRODUCE AN ERROR SIGNAL ONLY WHEN THE PULSE ARE DISPLACED IN PHASE FROM THE PARTICULAR SUBMULTIPLE OF OSCILLATIONS WHICH CORRESPONDS TO THE PRESCRIBED FREQUENCY. THE ERROR SIGNAL ACTIVATES A FREQUENCY-CORRECTION CIRCUIT COUPLED TO THE ELECTRONIC DRIVE CIRCUIT ASSOCIATED WITH THE TUNING-FORK MOTOR, WHEREBY THE PHASE OF THE PULSE DERIVED FROM THE ELECTRONIC CIRCUIT SHIFTS IN A DIRECTION TO BRING ABOUT PHASE-LOCKING WITH SAID SUBMULTIPLE.

摘要： The method for test the rate of an electronic watch with a time base device (1) comprises three main steps for the test on test equipment. The time base device comprises at least one watch module (2) with a resonator (3) connected to an oscillator of an electronic circuit (4), which is followed by a divider circuit, which is controlled by an inhibition circuit, and which provides a divided timing signal for a motor. In a first step, a measurement is made of the frequency of the oscillator reference signal in at least one measurement period without inhibition. A second step is provided for acquiring the current inhibition value to inhibit a certain number of clock pulses in a subsequently inhibition period and to determine the inhibition value. Finally, a third step is provided for calculating the corresponding rate frequency of the watch.
