Ultrasonic beam emitted from a probe 20 by said catalytic medium water is injected in a material 6 to be inspected while the reflected echo is received by the probe. In this case, it is necessary that the inner cylinder 32 is rotated at a concentric position with respect to the outer cylinder 31 when the material to be inspected is advanced into the probe holder. Therefore, the mass of the inner cylinder is made smaller than that of water excluded by a total volume and the buoyancy of the inner cylinder is utilized with respect to centrifugal force generated when the probe holder is rotated at a high speed to hold the inner cylinder concentrically. Restriction due to the bending of the material to be inspected is eliminated and flaw detection can be performed at a high speed in high efficiency.

Title: A/d converter
Inventor: TANI YASUNORI
IPC: H03M1/10
Filed: 1990-05-17
Abstract: PURPOSE:To make it difficult to be affected by surrounding noise by providing exclusive analog/digital(A/D) converters according to each of plural input levels set preliminarily and switching them according to the state of an analog input. CONSTITUTION:An analog signal is converted to a digital signal by A/D converters(ADC) 3 and 6. At that time, a selector 11 operates a switching operation. That is, when the signal amplitude of an inputted analog input is small, the selector 11 outputs a signal amplified by an amplifier 2 after the A/D conversion and when the signal amplitude of the analog input is large, the selector 11 outputs the signal directly after the A/D conversion. Thus, it is possible to always convert the analog signal with a large amplitude by the A/D converter even when the analog signal level is small and to make it difficult to be affected by the surrounding noise.
