ULTRASONIC INSPECTION INSTRUMENT

摘要

PURPOSE:To obtain an ultrasonic inspection instrument which is adapted to inspect the presence of a matter in a specimen automatically in a non-destructive manner. CONSTITUTION:A part requiring no detection of a specimen S is covered with a sound absorbing material of a container 7 for inspection and moved being held on a belt 5 of a conveyor 2. The specimen S moving is scanned by an ultrasonic beam with a transmitting/receiving scan type ultrasonic probe 11. The reflected wave from the specimen S is received by the ultrasonic probe 11. A judging section of an apparatus body 12 detects whether the arrival time of a receiving signal is in a fixed range or not to determine the acceptance or rejection of the specimen S.
