PURPOSE:To increase both the suppression effect to the ultrasonic beam and the working efficiency, by adhering through the heat hardening the powdered resin formed into an optional form to the areas other than the regular running path of the ultrasonic beam. CONSTITUTION:Powdered resin 17 formed into an optional form like a samll piece plate, etc. is adhered through the heat hardening to the areas other than the regular running path of the ultrasonic beam by piezoelectric oscillators 13 and 14 and shown by the dot-line arrows on glass medium 12. As a result, the suppression effect can be increased to the ultrasonic beam propagating the aras other than the regular route, at the same time enhancing the working efficiency. |
