Abstract
PURPOSE: To secure an accurate and highly efficient detection measurement of the signals by detecting and memorizing both the rise and fall of each detection pulse of the sensor in the measurement of the signal propagation speed in the metal and thus obtaining the stop signal of the counter.
CONSTITUTION: The sound wave is excited in alloy wire 2 by the control of minicomputer 5, and at the same time the clock given from generator 6 is supplied to counter 17 and 18. The propagation signal in wire 2 is detected by sensor 3 and 4 to be applied to input terminal 10 of the signal isolator circuit. The rise of the detection pulse given from sensor 3 is isolated 11 to stop counter 17 and also memorized 12. And when the output level is in agreement with the level of the fall time when given inverse detection 13, the signal level is memorized 14. On the other hand, the rise of the detection pulse is detected 15 for sensor 4, and the pulse delivered by the signal of circuit 14 stops counter 18. Computer 5 thus calculates the propagation speed of the signal based on the contents difference between counter 17 and 18, the clock pulse duration and the distance between sensor 3 and 4 each.
