Suppression of Mechanical Coupling

Parallel beam structure has many sagnaficant features, as follows. (a)The tap moves an parallel at the end. (aa) Thas structure converts the small dasplacement anto the concentrated large straan. (aza)Each unat doesn't anterfere to the other unats by palang up thas structures. We used thas structure for paezoelectmc vabratang gyroscope(angu1ar rate sensor). (av) The lateral rigadaty as hagh. We propose thzs structure for paezoelectmc vabratang gyroscope(angular rate sensor), and detected angular rate usang thas gyroscope. In thas paper, at zs shown the method fw super sensatazang by bnngang two resonance frequenczes(dmve resonance frequency and sensang resonance frequency) close. Then we propose the suppressaon method of the mechanacal couplang that anses by brangang two resonance frequencaes close. From thas result, thas structure mats for the gyroscope. Experamental results are shown.
