摘要： A temperature compensated clock and method of clocking systems are provided. The clock preferably has an oscillator for generating an oscillating waveform signal at a preselected frequency and a frequency divider responsive to the oscillator for dividing the frequency of the oscillating waveform signal. A temperature monitoring circuit is positioned responsive to a voltage input signal independent of temperature and a voltage input signal proportional to temperature for monitoring temperature variations. A temperature compensating circuit, preferably including a programmable scaling circuit, is responsive to the frequency divider and the temperature monitoring circuit for scaling the divided frequency of the generated waveform and thereby advantageously produces a temperature compensated output timing signal.

摘要： According to a rate adjusting method, the movement of a mechanical timepiece is first assembled. The assembled movement is then disposed in a vertical position, and the rate is measured with respect to a plurality of vertical positions. On the basis of the result of this rate measurement, the magnitude and direction of the positional difference vector are calculated. On the basis of the result of this calculaton, the amount of weight to be added to or subtracted from the annular balance of the movement is calculated and the positions on the annular balance where this amount of weight is to be added to or to be subtracted from is calculated. Based on the results of these calculations, the amount of weight is added to or subtracted from the annular balance at the calculated positions.
