Title: Ultrasonic measuring instrument
Inventor: KAJIWARA JUNICHI
IPC: G01N29/44
Filed: 1986-12-26
Abstract: PURPOSE:To efficiently measure an object body by providing a probe with an operation switch and receiving an ultrasonic wave received signal as an effective signal when the operation switch is on or off. CONSTITUTION:The transmitting probe 21 of a probe 20 sends out an ultrasonic wave and the receiving probe 22 receives the ultrasonic wave reflected by the surface of the object body. Its received signal is sent out to a peak holding circuit 8 and a necessary time section is selected with a gate signal 9 to detect the peak level of the received signal. Then the peak level signal is A/D converted 10 and inputted to a computer 11. When the operation switch 5 of the probe 22 is on, the computer 11 receives the signal from the A/D converter 10 to detect the peak level and make a numerical display 12. Further, the peak level is not detected when the operation switch 5 is off. In another way, the peak level may be detected when the operation switch 5 is off. Thus, the ultrasonic wave signal is received effectively, so a measurement is taken efficiently by limiting an object of measurement.
