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： A second housing (12) whose center portion (12a) is depressed and whose end portion (12b) around the center portion (12a) is formed like a visor is arranged around a first housing (11) whose center portion (11a) is depressed and whose end portion (11b) around the center portion (11a) is formed like a visor, and a hollow portion (14) is formed between the first housing (11) and the second housing (12) by sandwiching a packing (13) between the end portions (11b,12b) of the housings (11,12). Further, degassed water (15) for preventing empty heating is filled in the hollow portion (14), and an ultrasonic transducer (16) is placed on the surface of the center portion (11a) of the first housing (11). A weight (17) for preventing the vibration of the wall (12c) is provided on the wall surface of the second housing (12). Since the vibration of the wall (12c) of the housing (12) is suppressed by the weight (17), vibration energy returns toward the bottom surface of the center of the housing (12) through water and is radiated from the bottom surface efficiently as ultrasonic waves.
摘要翻译： 其中心部分（12a）被压下并且其中心部分（12a）周围的端部（12b）形成为类似于帽檐的第二壳体（12）围绕中心部分（11a）被压下的第一壳体 （11a）周围的端部（11b）形成为像遮阳板一样的形状，在第一外壳（11）和第二外壳（12）之间夹有填料（13）形成中空部分（14） 在壳体（11,12）的端部（11b，12b）之间。 另外，在中空部14中填充防止空热的脱气水15，在第一壳体11的中央部11a的表面配置超声波振子16。 在第二壳体（12）的壁表面上设置有用于防止壁（12c）振动的重物（17）。 由于壳体12的壁12c的振动通过配重17被抑制，因此振动能量通过水向壳体12的中心的底面返回，并且从底面有效地放射 作为超声波。
