    • The circuit comprises a counter (13), a generator (11) that produces a reference signal (Sf) made up of pulses, and a two-input AND gate (10). One input of the AND gate is connected to the generator while the other input receives a signal (Sx) produced by a bouncing contact (X) as it switches from an open position to a closed position and vice versa. The output of the AND gate is connected to the clock input (C113) of the counter, which further has a reset input (R13) connected to the output of an inverter (14) whose input receives the signal produced by the contact.Opening of the contact causes the reference signal to be blocked by the AND gate and the counter to be reset. Closure of the contact causes the AND gate to open to the reference signal whose pulses then increment the counter and the latter, upon its contents reaching a predetermined value, issues an output signal (S13) in the form of a pulse.
    • 电路包括计数器(13),产生由脉冲组成的参考信号(Sf)的发生器(11)和双输入与门(10)。 与门的一个输入连接到发生器,而另一个输入接收到由弹跳触点(X)产生的信号(Sx),因为它从打开位置切换到闭合位置,反之亦然。 与门的输出连接到计数器的时钟输入(C113),该输入还具有连接到反相器(14)的输出端的复位输入(R13),其输入接收由触点产生的信号。 触点断开会导致参考信号由与门阻塞,计数器被复位。 触点的闭合使AND门打开到参考信号,其脉冲然后递增计数器,而后者当其内容达到预定值时,以脉冲的形式发出输出信号(S13)。

    • A time base including a resonator (4) and an integrated electronic circuit (3) for driving the resonator into oscillation and for producing, in response to the oscillation, a signal having a determined frequency. The resonator is an integrated micromechanical ring resonator supported above a substrate (2) and adapted to oscillate in a first oscillation mode. The ring resonator includes a free-standing oscillating structure (6). Electrodes (100, 120; 130, 150) are positioned under the free-standing oscillating structure in such a way as to drive and sense a second oscillation mode in a plane substantially perpendicular to the substrate and having a resonant frequency which is different from the resonant frequency of the first oscillation mode, a frequency difference between the resonant frequencies of both oscillation modes being used for compensating for the effect of temperature on the frequency of the signal produced by the time base.

    • There is described a time base comprising a resonator (4) and an integrated electronic circuit (3) for driving the resonator into oscillation and for producing, in response to the oscillation, a signal having a determined frequency. The resonator is an integrated micromechanical ring resonator supported above a substrate (2) and adapted to oscillate around an axis of rotation (O) substantially perpendicular to the substrate, the ring resonator comprising a central post (5) extending from the substrate along the axis of rotation, a free-standing oscillating structure (6) connected to the central post and including an outer ring (60) coaxial with the axis of rotation and connected to the central post by means of a plurality of spring elements (62), and electrode structures (9; 9*) disposed around the outer ring and connected to the integrated electronic circuit. The free-standing oscillating structure further comprises a plurality of thermally compensating members (65) which are adapted to alter a mass moment of inertia of the free-standing oscillating structure as a function of temperature so as to compensate for the effect of temperature on the resonant frequency of the ring resonator.
