Abstract
Each resonant frequency of a coupling resonator is measured at a plurality of each different temperatures. From these values the first order temperature coefficient .alpha. is calculated. According to the value of .alpha., it is accurately adjusted and finally the resonant frequency of a fundamental vibration is also adjusted to a nominal frequency.
