    • The present invention discloses a magnetic recording medium comprised by sequentially layering a magnetic recording layer, intermediate layer and concealment layer on a non-magnetic substrate made from a thermoplastic resin, wherein the surface of the intermediate layer forms a single smooth surface with the surface of the non-magnetic substrate as a result of embedding the magnetic recording layer and the intermediate layer within a portion of the non-magnetic substrate, and the concealment layer conceals the surface of the intermediate layer and the surface of the non-magnetic substrate. This magnetic recording medium has superior concealment and adhesion of the concealment layer for the magnetic recording layer as well as a high level of design properties regardless of the type of magnetic particles used in the magnetic recording layer.

    • In a cutter bit abrasion detecting device of a shield excavator comprising a plurality of cutter bits arranged on the front surface of a cutter head rotatably provided in front of a shield body for excavating a working place, a sensor hole or sensor holes are formed in each of some of the cutter bits and sensor heads each comprising a U-shaped single-core optical fiber accommodated in a casing are inserted thereinto. As a result, sensor heads can be thin to be easily inserted into the sensor holes having a small diameter so as to be set in cutter bits with ease since the single-core optical fiber is employed and the attenuation of light received by the sensor head can be reduced due to the attenuation of light between a reflector plate and the optical fiber since no reflector plate is employed, so that accuracy in detection is improved.
    • 一种盾构式挖掘机的刀具磨耗检测装置,其特征在于,具备:设置在所述切割头的前表面上的多个切削刀头,所述切削刀头可旋转地设置在用于挖掘工作场所的屏蔽体的前方,形成有传感器孔或传感器孔 每个包括容纳在壳体中的U形单芯光纤的一些刀头和传感器头插入其中。 结果,传感器头可以很薄以便容易地插入到具有小直径的传感器孔中,从而容易地设置在切割刀头中,因为使用单芯光纤并且由传感器头接收的光的衰减 可以由于反射板和光纤之间的光衰减而减少,因为没有使用反射板,从而提高了检测精度。
