    摘要: An achromatized beam splitter of a low polarization comprising a transparent first prism, a transparent second prism and a thin film group provided between the first prism and the second prism. The thin film group comprises, in succession from the first prism to the second prism, a first dielectric material thin film layer provided on the inclined surface of the first prism which first layer is a mixture of titanium oxide and zirconium oxide, a metal thin film layer provided on the first dielectric material thin film layer which metal layer consists of silver, and a second dielectric material thin film layer provided on the metal thin film layer which second layer is a mixture of titanium oxide and zirconium oxide. The second dielectric material thin film layer has a film thickness substantially equal to that of the first dielectric material thin film layer.

    摘要: First and second magnetic poles are provided, which have end surfaces brought close and in opposition to a material to be examined. These magnetic poles are magnetized by a DC exciter coil such that the magnetic poles have opposite polarities. The first magnetic pole is provided at its end surface with a pair of cumulatively connected transmitting coils, and the second magnetic pole is provided at its end surface with a pair of differentially connected receiving coils. The transmitting coils are connected to a pulser which generates a pulse current, and the receiving coils are connected to a differential amplifier. An electromagnetic ultrasonic wave generated by the transmitting coils are received by the receiving coils, amplified by the differential amplifier, and thereafter supplied to a synchroscope and an automatic detector.

    摘要: In a centerless grinding apparatus, a first and a second guide plates are disposed on the side of a grinding wheel, as well as a third and a fourth guide plates are disposed on the side of a regulating feed wheel in parallel relation to the first and second guide plates. The grinding wheel is set to protrude from a guide surface of each of the first and second guide plates by a grinding width, and the regulating feed wheel is set to protrude from a guide surface of each of the third and fourth guide plates by a feed width. The guide surface of each of the third amd fourth guide plates is curved into a curvature equal to a curvature of the outer periphery of the regulating feed wheel.
