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.
