Method of adjusting frequency of NS-GT cut quartz resonator.

摘要

The present invention discloses a NS-GT cut quartz resonator (4) which has an extremely excellent frequency-to-temperature characteristic by changing the coupling condition of the resonator using weights (5,6) deposited on at least one end of said resonator. The manufacture of the resonator includes a step of adjusting the normalized frequency according to the relationship between the normalized frequency and the first order temperature coefficient to adjust the first order temperature coefficient to substantially zero. <IMAGE>
