摘要： PROBLEM TO BE SOLVED: To provide a magnetic material bent part rupture inspection method and a magnetic material bent part rupture inspection device capable of detecting rupture at a bent part of a magnetic material at low cost by a nondestructive procedure. SOLUTION: The rupture at the bent part Sc of a long cylindrical magnetic material S2 covered with a covering body C is inspected. A detection head 10 for detecting a magnetic flux change caused by excitation of an excitation core is provided near a pair of ends 11a, 11b of the excitation core. The pair of ends 11a, 11b of the excitation core are oriented along the longitudinal direction of the magnetic material, and the excitation core is excited and simultaneously moved in the far-and-near direction relative to the bent part Sc together with the detection head 10. The rupture is inspected from a detection result of the magnetic flux change by using the detection head 10 near the bent part Sc caused by the movement. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a method for inspecting a cavity of a concrete structure capable of inspecting the presence/absence and the extent of the cavity by boring a part of the cavity.SOLUTION: A hole is bored in a concrete structure 100. Gas is made to flow in or out (hereinafter, referred to as "flow in and the like") from the hole 130 at a prescribed pressure. The volume of the cavity 120 communicated with the hole 130 is measured by a time fluctuation of the measurement pressure at a low pressure range when the measurement pressure starts to increase after starting the inflow. The volume of the cavity 120 communicated with the hole 130 is measured by the time fluctuation of a pressure ratio that is obtained by dividing the measurement pressure by a prescribed value when the measurement pressure reaches.

摘要： PROBLEM TO BE SOLVED: To provide a method and device for simply and more reliably inspecting fracture of a magnetic material such as a reinforcing bar.
SOLUTION: The device includes a detection head 10 for detecting a change in magnetic flux caused by the excitation of an exciting coil at a bend part Sc of a rod-like magnetic material S2 covered with a coating body. A fracture in the bend part Sc of the magnetic material S2 is inspected by using a Lissajous's waveform produced based on a signal of the detection head 10. The signal is obtained by exciting the exciting coil at two different frequencies. By adjusting the phase and amplitude of at least one Lissajous's waveform out of Lissajous's waveforms produced based on signals of respective frequencies, it is made possible to adjust a composited waveform thereof with the other Lissajous's waveform.
