Abstract: <P>PROBLEM TO BE SOLVED: To provide a circuit which can detect minute constance difference in two resistors, coils, capacitors, etc., and to realize and provide a location detecting device and an identification inspecting device, etc., of defects of conductor or its presence or absence which use the circuit.  <P>SOLUTION: Energization and control are simultaneously conducted on two nearly identical RLC circuits. The difference in the transient response is converted into a time width, from the time of energization switching to the time, when a prescribed transient response potential difference is obtained. The time width is digitized, by counting the pulses of minute interval. Since the difference of the constants of the two sets of the RLC circuits is small, the time width becomes large, the difference can be expanded through digitization and can be identified. These detection circuits are applied to the location detecting device and to the identification inspection device of defect or existence of a conductor, thereby significantly improving the detection sensitivity.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
