Abstract
PURPOSE:To offer a miniature tuning fork type bending quartz oscillator having less loss resistance and high frequency, by providing at least a linking section linking nodes of a tuning fork arm, suppressing the fundamental oscillation and the secondary harmonic oscillation and exciting the ternary harmonic oscillation. CONSTITUTION:Linking sections 4 and 5 are provided around 0.5l (where; l is the lenght of a tuning fork arm) and 0.868l from the base of tuning fork of a tuning fork type bending oscillator. One linking section 4 is provided around 0.5l from the tuning fork base. The linking section 5 is provided around 0.868l from the base of tuning fork to suppress the fundamental oscillation 1 and the secondary harmonic oscillation 2, allowing to easily excite only the ternary harmonic oscillation 3.
