Description
富川義朗著 「超音波エレクトロニクス振動論―基礎と応用」 朝倉書店 1998年
また、超音波送信器として広帯域の超音波を送信する際に、送信波の帯域内に共振子の固有振動数が存在するとその振動数において共振子の歪みが大きくなるため必要とする破壊強度も大きくなる。このため共振子の固有振動数は超音波送信器の第一共振周波数を中心とする使用帯域外にあることが望まれる。

Claims (1)
- 開放型超音波送信器において、共振子の固有振動数を超音波送信器の第一共振周波数を中心とする使用帯域外になるようにする為に、前記共振子の素材としてマグネシウムあるいは組成比率80%以上がマグネシウムであるマグネシウム合金を用いたことを特徴とする開放型の超音波送信器。
