摘要： A non-destructive inspection apparatus includes a magnetic field applying device and a magnetic sensor. The magnetic field applying device is adapted to apply DC and AC magnetic fields to an object to be inspected. Degradation/damage of the object is detected by measuring a magnetic characteristic of the object in a state in which the DC and AC magnetic fields are applied. Also, a non-destructive inspection apparatus includes as a magnetic sensor a plurality of pickup coils and a SQUID(s) connected to the pickup coils and decides the form of a defect of an object to be inspected by producing a difference between outputs of the pickup coils or SQUIDs.

摘要： There is provided an apparatus for picking up a defective portion replica that can pick up a replica with high accuracy and positively even from a surface of a structure in the water. Within a container part provided at a leading end of a replica pickup part is displaced a deformable member, such as a porous expansion member, which is excellent in adhesion with a replica and which deforms when a replica material is poured into a gap between a surface of a structure and the deformable member. The replica material from the replica material supply nozzle is poured into the gap between the surface of a structure and the porous expansion member and the replica is recovered by making use of adhesion with the porous expansion member.
