    • A method is provided for securely holding a spectacle lens. Without using screwing members such as a screw and a nut, and extra parts such as a bush, a cylindrical pin and a slip-off preventive pin, a spectacle lens can surely be held. A taper pin is provided projecting on a lens holding member for holding a spectacle lens, and a taper hole having approximately the same size as the taper pin is provided on the spectacle lens. The taper pin is directly press-fitted into the taper hole, thereby holding the spectacle lens by a press-contact between an inner circumferential surface of the taper hole and an outer circumferential surface of the taper pin. The taper pin is press-fitted in a thickness direction of the spectacle lens.
    • 提供了一种可靠地保持眼镜镜片的方法。 不使用诸如螺钉和螺母的螺纹构件,以及诸如衬套,圆柱销和防脱销的额外部件,可以可靠地保持眼镜镜片。 设置在用于保持眼镜片的透镜保持构件上突出的锥形销,并且在眼镜镜片上设置有与锥形销大致相同尺寸的锥形孔。 锥形销被直接压入锥形孔中,从而通过锥形孔的内周面和锥形销的外周面之间的压接而保持眼镜镜片。 锥形销在眼镜镜片的厚度方向上压配合。

    • A perpendicular magnetic recording medium composed of a nonmagnetic substrate having a surface onto which are provided a plurality of layers including, in the order recited, a soft underlayer; a nonmagnetic coupling layer; a hard magnetic pinning layer which is antiferromagnetically coupled to the soft underlayer at ambient temperature via the nonmagnetic coupling layer and which has an axis of easy magnetization which extends in a direction which is perpendicular to that of the surface of the nonmagnetic substrate; a nonmagnetic intermediate layer; and a magnetic recording layer. Such a perpendicular magnetic recording medium has an improved medium performance, with reduced noise originating from the presence of the soft underlayer, and no erasure of recorded magnetization when influenced by an external magnetic field.
