Patent JP-S50161274-A (JP)
IPC: G04D7/10
Filed: 1974-06-18
Abstract: An apparatus for adjusting the frequency of an oscillating element provided with a hair sp extracts an oscillating signal from the oscillating element which is oscillated by the elastic force of the hair spring. High frequency pulses are counted by a counter during a predetermined period of the oscillation signal. On the other hand, further high frequency pulses are counted by another counter. When the count value of the latter counter coincides with that of the former counter, the input pulses to the latter counter are stopped by the coincidence output. Until the coincidence between the count values of both the counters is established, the hair spring is transported to adjust the length thereof. Thereafter, the unnecessary hair spring is cut away. Since this apparatus detects an appropriate length of the hair spring by electronic circuitry, it is small in size, and the unnecessary length of hair spring is automatically cut away.
