ULTRASONIC GENERATOR, SONIC VELOCITY MEASURING EQUIPMENT USING ULTRASONIC GENERATOR AND SONIC VELOCITY MEASURING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a ultrasonic generator or a sonic velocity measuring equipment capable of measuring sonic velocity value even in the case that installation place is limited.;SOLUTION: The sonic velocity measuring device has ultrasonic generation equipment formed as a receiving/oscillating part which is integrated an oscillation part and a receiving part of ultrasonic wave that has an acoustic lens unit for correction for enabling the receiving oscillating part to receive reflection wave in the case that ultrasonic oscillated from the receiving/oscillating part is reflected to a different position from the receiving/oscillating part, a turnaround time measuring unit for measuring reciprocating time of ultrasonic by using the ultrasonic generating device and a sonic velocity measuring unit for measuring sonic velocity value based on the turnaround time.;COPYRIGHT: (C)2004,JPO
