Abstract
PURPOSE: To measure the width of slide face exactly by removing the distortion of signal wave form and the noise component contained before and after the signal when measuring the trolley wire slide face width.
CONSTITUTION: A signal from the reflected ray on the trolley slide face, a part of which is delayed a fixed time in which a rise time is regarded in the delay circuit 10, becomes the signal wave B through the level regulating ciruit 9. A part of the original signal is compressed by the amplitude compressor 11, both signal waves are compared with each other by the comparator 12 to obtain the output E. On the other hand, the delay signal is also compressed and compared with the original signal by the comparator 14 to obtain the output F. The original signal wave A and the delay signal wave B are compared with a reference voltage in the comparators 16, 17 to obtain the signals G, H respectively. When the logical product of A, B, G and H is taken, the voltage change parts E', E", F' and F" in the output waves E, F corresponding to the noise component in the original signal A are removed.
