<p><P>PROBLEM TO BE SOLVED: To provide an ultrasonic sterilization/decomposition apparatus capable of utilizing ultrasonic waves irradiating a channel for a liquid for sterilization or decomposition of bacteria or microorganisms with large energy while suppressing an adverse effect on surrounding facilities. <P>SOLUTION: The ultrasonic waves 10 generated from an ultrasonic transducer 3 are converged inside the channel for the liquid 2 by a lens 4. The materials of piping 1 and a filler 6 between the lens 4 and piping 1 are materials having almost the same level of acoustic impedance as the liquid 2. The energy loss of the ultrasonic waves 10 is suppressed as much as possible to be converged, thereby sterilizing or decomposing the bacteria or microorganisms. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
