 note = {In order to carry out the easy and accurate detection of the shell-plate-flaw in
steel fishing vessels, irrespective of the inspection-location, whether at sea or in docking,
a simplified ultrasonic shell-plate-flaw-detector for fishing vessels was devised with the
use of the standing wave technique in thickness-measurement.
As the result of the repeated experiments the effectiveness of the newly devised
detector was proved to be generally good, with the accuracy lying within 3% mean
error in the thickness-measurement (max. 5%) ; with the confirmation that by the
observation of resonance-image-changing phase even the flaw-depth could be detected,
though, at present, whether it was in contact with salt water or not, it was better that
there was no paint and no curvature on the plate surface.},
