Filed: 1988-06-24
Abstract: PURPOSE:To achieve a higher flaw discrimination capacity by providing a Z comparative computation circuit to detect the maximum value of a maximul value of a Z signal within a specified time. CONSTITUTION:A Z comparative computation circuit 115 monitors a minimal value ¦Zmax¦ of a Z signal to detect the maximum value ¦Zmax¦max of the maximal value ¦Zmax¦ within time as given by dividing a length of a detection coil by a passage speed V of material to be inspected. A selection means 110 forces a matrix decider 109 to make a selection corresponding to a phase angle tan<-1> (Vy/Vx) derived from the maximum value ¦Zmax¦max and values of an X signal Vx and a Y signal Vy providing the maximum value. Hence, each time an X axis signal and a Y axis signal are detected, a formula (Z<2>=X<2>+Y<2>) is calculated and a value Z<2> is monitored to determine the maximal value thereof and the X and Y signals thus obtained are held. Likewise, the subsequent maximal value is determined to be compared with the maximal value determined at the first time and the larger one is set as the maximum value of the value Z<2>. When the maximal value of the value Z<2> determined following the third time is larger than the maximum value, the maximum value is updated. The maximum value thus obtained is defined as representative value of a corresponding flaw.
