摘要： 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.

摘要： In an analog type of timepiece equipped with an alarm, an alarm time coincidence detection mechanism and a zero seconds detection mechanism are provided whereby switch contacts are closed when alarm time coincidence and zero seconds are detected respectively. A logical product is formed by combining signals from said switch contacts such that an operating signal to actuate an alarm device is produced with a high degree of accuracy. A memory circuit is incorporated to eliminate the effects of imperfect switch contact.

摘要： A switching circuit including a flip-flop which receives a switching signal that sets the flip-flop and which receives a reset signal which resets the flip-flop. A latching circuit, responsive to a clock signal, is connected to receive an output signal of the flip-flop for developing a latching circuit output signal corresponding to the output signal of the flip-flop at a time the clock signal is applied thereto. A reset signal and a clock signal developed repetitively and out of phase are respectively applied to the flip-flop and the latching circuit so that the latching circuit output signal can change only after the flip-flop has been reset.

摘要： A chattering prevention circuit includes a counter, which upon receiving an input signal including a chattering signal such as from a switch contact, begins to count a clock signal. When the count reaches a predetermined value, a gate signal is generated which, in turn, is employed to gate the input signal. The input signal is delayed by a time corresponding to the period during which the chattering phenomenon remains in effect following the closing of the contact, thereby to prevent chattering.
