Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To judge plasticization and its position according to the distribution condition of magnetic field by scanning the surface of steel with a differential type magnetic sensor. SOLUTION: When a magnetic sensor 10 is placed close to the surface of a steel 1, it detects vertical elements of a magnetic field, and it is moved in parallel to the steel 1 so as to scan the surface thereof and obtain the one- dimensional distribution of intensity of the magnetic field. Further, the entire surface of the steel 1 is scanned square with the sensor 10 so as to obtain the plane distribution of intensity of the magnetic field. Then, scanning points is prepared on the respective scanning lines according to sampling frequency, and the intensities of magnetic field at the respective scanning points are converted into digital values through an A/D converter, then the points out of respective scanning points that are the same in magnetic field intensity are connected with each other to prepare a similar magnetic line diagram.  When any magnetic anisotropy is generated internally due to plasticizing deformation, any distribution of magnetic field caused by magnetic anisotropy occurs externally, and its phenomenon is reflected on the prepared diagram. Thus, the result is analyzed so as to judge the plasticization of the steel 1.

Further, when highly close contact properties are considered, it is pref. that the elastomer is absent on the front part of the absorbable article 1. By this method, the absorbable article wherein both of leakproof properties and a use feeling are considerably well is obtained.
