发明名称 QUARTZ CRYSTAL RESONATOR.
摘要 <p>A tuning fork type quartz crystal resonator may be used to generate higher harmonic oscillations at the base portion thereof by appropriate selection of the width (W) and thickness (t) of an arm portion of the resonator as well as the cut angle of the original crystal. This tuning fork type quartz crystal resonator generating higher harmonic oscillations shows stable characteristics against temperature changes.</p>
