Title:
ULTRASONIC WAVE TRANSMISSION LINE AND ULTRASONIC WAVE UTILIZATION DEVICE
Document Type and Number:
Japanese Patent JP2018042185
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent an ultrasonic wave from being attenuated by absorbing ultrasonic vibration in a tube wall normally when an ultrasonic waveguide put into a hollow tube or an object holding the ultrasonic waveguide is brought into contact with the tube wall in an ultrasonic wave transmission line.SOLUTION: The present invention relates to an ultrasonic wave transmission line connecting an ultrasonic wave transmission part of an ultrasonic wave generation device with an ultrasonic wave reception part of an ultrasonic wave utilization device. The ultrasonic wave transmission line includes: a waterproof and flexible hollow tube; a rod-shaped or tabular flexible ultrasonic waveguide disposed in a length direction inside of the hollow tube and capable of propagating a transverse wave, a longitudinal wave or Lamb wave; and a support member which is disposed while being fixed on an inner wall of the hollow tube with spacing of a half wavelength or an integer multiple of the half wavelength of the ultrasonic wave, and brought into partial contact with the ultrasonic waveguide for supporting the ultrasonic waveguide in such a manner that the ultrasonic waveguide is prevented from being brought into contact with the inner wall of the hollow tube.SELECTED DRAWING: Figure 1
