摘要： A second housing whose center portion is depressed and whose end portion around the center portion is formed like a visor is arranged around a first housing whose center portion is depressed and whose end portion around the center portion is formed like a visor, and a hollow portion is formed between the first housing and the second housing by sandwiching a packing between the end portions of the housings. Further, degassed water for preventing empty heating is filled in the hollow portion, and an ultrasonic transducer is placed on the surface of the center portion of the first housing. A weight for preventing the vibration of the wall is provided on the wall surface of the second housing. Since the vibration of the wall of the housing is suppressed by the weight, vibration energy returns toward the bottom surface of the center of the housing through water and is radiated from the bottom surface efficiently as ultrasonic waves.

摘要翻译： 中心部分被压下并且其中心部分的端部形成为遮阳板的第二壳体围绕中心部分被压下并且其中心部分周围的端部形成为遮阳板的第一壳体布置，并且中空部分 通过在壳体的端部之间夹住填料而形成在第一壳体和第二壳体之间。 此外，用于防止空加热的脱气水填充在中空部分中，并且超声换能器被放置在第一壳体的中心部分的表面上。 用于防止壁的振动的重量设置在第二壳体的壁表面上。 由于壳体的壁的振动受到重量的抑制，振动能量通过水返回到壳体中心的底面，并且作为超声波有效地从底面辐射。
