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。 As shown in FIGS. 1 and 2, the conventional resonator 1 has a rectangular shape and is made of aluminum, titanium,
It is made of iron or the like, and when the central part of the excitation surface 2 is excited, it resonates at a half wavelength of a longitudinal wave in the dimension with the work surface 3 on the opposite side. and,
A reduced cross-sectional area 5 is provided from the vibration node 4 to the working surface 3, so that an increased displacement amplitude on the working surface 3 can be obtained. Further, a plurality of slits 6, 6, . . . are provided over the region of the joint portion 4 to prevent Poisson coupling.
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。 However, when the width of the resonator 1 increases, the working surface 3 may have an uneven amplitude distribution. That is, as shown in FIG. 3, when the maximum swing width is 1, the swing width is 1 in the central part, but the swing width decreases toward the side parts.
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。 For example, when a resonator is used to join thermoplastic resin, the center part of the resonator is welded to meet the desired joining specifications, but the side parts are not fully welded and cannot be properly welded. The drawback was that it could not meet the initial joint specifications.
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
に関係するものである。 The amplitude expansion rate (including reduction rate) between the excitation surface and the working surface of a half-wavelength resonator is related to the ratio of the cross-sectional area from the excitation surface to the vibration node and the cross-sectional area from the vibration node to the work surface. It is something to do.

Usually used frequencies are 5KHz~60K
Hz, and when the excitation surface 2 is excited, it is amplified and causes the work surface 3 to vibrate. This vibration causes the work surface 3
