波の半波長共振するようになつている。そして、
振動の節部４から作業面３に亘つて断面積の減少
部５を設けて、作業面３に増大された変位振巾が
得られるようにしている。又、節部４の領域に亘
つてポアソンカツプリングを防止するように複数
個のスリツト６，６，…を設けている。
しかしながら、前記の共振体１においては、巾
が大きくなると、作業面３において不均一な振巾
分布を持つようになることがある。即ち、第３図
に示すように、最大振巾１とした場合、中央部は
振巾１を示すが、側方部に行くにしたがつて振巾
が減少する。
このことは、例えば、共振体を熱可塑性樹脂の
接合に用いた場合、共振体の中央部付近は溶着し
て所期の接合仕様を満足させるが、側方部におい
ては溶着が不十分で所期の接合仕様を満足できな
いという欠点があつた。
半波長共振体の励振面と作業面との振巾拡大率
（減少率も含む）は、励振面より振動節部までの
断面積と、振動節部より作業面までの断面積の比

長共振する振動伝送体（通常ブースタホーンと呼
ばれる）を介して共振体１の励振面２の中央部を
励振する。通常使用される周波数は5KHz〜60K
Hzであり、励振面２が励振されると、増巾されて
作業面３を振動させる。この振動により作業面３
により各種の作業を行うが、この作業面３の振動
