    摘要: A timepiece which includes a case (2), a horometric movement (4) housed within the case (2) and means for broadcasting an electromagnetic signal including electronic means (12) for furnishing the signal and at least one broadcasting antenna (14) coupled to the electronic means (12). Such timepiece is characterized in that the antenna (14) is arranged on a first face (20a) of a support plate (20) of basically planar form arranged in the interior of the case (2), such antenna (14) being constituted by a thin metallic layer deposited on the face (20a) of the support plate (20). This timepiece is applicable to the control of an arrangement, for example for latching and unlatching, of a door in particular.

    摘要: A highly stable frequency generator (G) comprises an oscillator (10) for generating a first frequency (F1), and further comprises a time base (BT) providing a time stable frequency signal which is independent of the temperature, and a feedback circuit arranged to provide a first number of pulses (n.sub.T) coming from the oscillator (10) to a comparing circuit (13), a circuit (14) for providing a reference number of pulses (N.sub.T) to said comparing circuit (13), and a circuit (13,15,16) providing a correction signal (Sc) as a function of the difference (.DELTA.) between the first number (n.sub.T) and the reference number (N.sub.T), the generator (G) further comprising a correction circuit (17) of the oscillation frequency (F1) of said first oscillator (10), this correction circuit being controlled by said control signal (Sc).
