    摘要： There are disclosed an improved method for production of a polarizing glass having a high extinction ratio by facilitating control of the diameter of silver halide particles in a mother glass with high Ag concentration, and a polarizing glass produced by the method. The glass is a polarizing glass having dispersed and oriented geometrically anisotropic metallic silver particles at least in its surface layer, which is characterized by not containing TiO2 exceeding 1.7 wt % but containing not less than 0.4 wt % Ag, and in that Ag and halogens contained therein satisfy the following relations: the molar ratio of Ag/(Cl+Br) is 0.2 to 1.0; the molar ratio of Cl/(Cl+Br+F) 0.5 to 0.95; and the molar ratio of Br/(Cl+Br+F) 0.05 to 0.4. The method for production comprises the steps of drawing a glass containing dispersed AgClxBr1-x crystals, and then reducing it under a reducing atmosphere.

    摘要： A magnetic sensor in which magnetic leakage flaw detection can be performed with high accuracy without so reducing liftoff, and a magnetic flaw detection method and apparatus to which the magnetic sensor is applied. The magnetic sensor 50 for detecting magnetic flux generated due to a defect portion of a magnetized subject to be inspected has an E-shaped core 51 having magnetic poles (51a, 51b and 51c) arranged in the neighborhood of a steel plate (13) to be inspected, and a search coil (52) wound on the center magnetic pole (51b) of the E-shaped core for detecting the magnetic flux. An external magnetic field floating in the circumference of the E-shaped magnetic sensor passes through the opposite side magnetic poles (51a and 51c) of the E-shaped core 51 but does not cross the center magnetic pole (51b) of the E-shaped core. Accordingly, no voltage due to the external magnetic field is induced in the search coil (52), so that only the magnetic flux caused by the defect portion is detected. Accordingly, the directivity with respect to the external magnetic field is improved so that the generation of a noise voltage due to the external magnetic field is suppressed and S/N at the time of flaw detection is improved.
