A synchronizing circuit that is capable of generating a reproduced clock signal synchronized with a reference clock signal without causing a false lock and a clock data recovery circuit including the same are provided. An oscillation or vibration of the measurement instrument is recorded and taken into account in the measurement. A double closed flux path structure that uses three magnetic layers is employed with magnetic coupled structure in both ends of the track. The chisel cutting tool can be moveable relative to a selected trial implant or the chisel cutting tools can be fixed onto a trial implant shaped body portion. This is primarily due to the early saturation effect of OFETs having very thin semi-conducting layers, and, furthermore, to the use of OFETs having specific properties as the organic logic components and to a novel layout of the circuit containing these logic components.
