Abstract
PURPOSE:To simplify the frequency adjustment, by giving a weight at the end broadwise around nodes of bending harmonic oscillation. CONSTITUTION:When a tuning fork type oscillator 3 oscillates, the point where displacement is zero is in existence at the B around the tip of arm other than the base. When a weight is added to the broadwise end of the node B of this oscillation, the frequency of tortional oscillation only can be changed without changing the frequency of bending secondary harmonic oscillation, and the adjustment is made easy.
