Abstract: Rate change in a quartz crystal timepiece due, for example, to aging of a capacitance used for correcting the frequency-temperature characteristic of the crystal oscillator of the timepiece, is corrected by dividing the oscillator output signal to provide a minimum rate adjustment unit signal and a rate adjustment timing signal. A rate adjustment step width signal consisting of a number of minumum rate adjustment unit signals is predetermined for all of the timepieces in a production run. The number controls the repeated counting of unit signals to produce a series of step width signals. The rate adjustment required for correct timekeeping is determined as an integral number of step width signals. The latter number is set into a second counter in the timepiece to generate a rate adjustment signal. The rate adjustment signal controls the duty cycle of a switch which adds reactance to the crystal oscillator circuit to effect the rate change.

Abstract: A chattering preventive circuit for preventing chattering in a switch having a mechanical contact. The circuit includes a switch element for producing an input signal representative of the open and closed states of the switch and also includes a periodic pulse signal. A first memory circuit receives the input signal and the periodic pulse signal and produces a write-in signal representative of the coincidence of the input signal and the periodic pulse signal. A second memory circuit receives the write-in signal and the periodic pulse signal and produces an output signal representative of the closed state of the switch element only when the switch element is kept closed for at least a predetermined time period. The second memory circuit will not produce the next output signal representative of another closing of the switch element unless the switch element first remains open for at least a predetermined time prior to reclosing.

Abstract: A signal produced by connecting the electrical contacts of a mechanical switch is read into a circuit without chatter only when the switch is closed longer than a selected time period. A first memory stores and outputs a switch actuation signal on the occurrence of a read signal, and erases the stored signal when the switch actuation signal is removed. A second memory outputs a square wave pulse on the coincidence of a later read signal and the first memory output. Electrical noise lasting less than the selected time period does not produce an output. The selected time period can be varied by using independent, phase-shifted read signals for each memory.

Occurrence of a logic state in a subsequent divider stage enables the circuits for the next periodic application of the correcting data. Coarse and fine adjustments can be made.
