The integrated values of the detected AE waves corresponding to the numerous points X 1 , X 2 ... are summed up by an energy summing-up circuit 28 depending on signals of the positions of the sound sources to indicate the energy of cracks on a monitor 30. The length of the cracks and the time-dependent change in the length are calculated by a crack length propagation speed calculating circuit 34 from the cracking energy and the average value of stress measured by a stress measuring circuit 32 and a sensor S 3  such as a strain gauge. The crack length and the crack propagation speed are thus determined to raise an alarm if necessary.

Abstract: PURPOSE:To enable the observation of a magnetic domain structure in non-destructively and with a high resolution, by measuring the intensity of light according to changes in magnetization with relative movement of a sample and a light spot to perform a mapping for moving distance and the intensity of light. CONSTITUTION:Light from a light source 1 turns to a parallel light with a collimeter lens 4 via a condenser lens 2 and a slit 3 to be made incident into a sample surface through a polarizer 5 and a slit 6. The reflected light from a sample passes through an objective lens 9, an analyzer 10 and an eyepiece 11 to observe the magnetic domain structure on a photographic film 12 and a bright and dark pattern is observed corresponding to the magnetic domain of a sample as shown by (b). In the electric measurement, a light receiving element 12' is used in place of the film 12 and a magnetic field generator 13 such as Helmholtz to facilitate the measurement of an M-H curve. A sample is placed on X-Y-Z stage 8 and then, for example, the stage is moved in the direction of Y. The element 12' receives the density of light corresponding to the magnetization of the sample to obtain an electrical signal as shown by (c). Thus, the observation of the magnetic domain structure can be done with a high resolution by a mapping with an X-Y scanning.
