    • A device for locating an object concealed behind a piercable member which is less dense than the object comprises a handle with a thin elongated needle mounted on the handle. The location of a denser object concealed behind the piercable member, such as a stud located behind drywall, is indicated by driving the needle through the drywall at selected points until a stud is struck. The locating device preferably includes a collar member surrounding and embracing the piercing end of the needle which provides lateral support for this part of the needle. The collar telescopes within a bore provided on the handle during penetration of the piercable member, with the collar being biased outboard relative to the bore to assure such lateral support at the point of needle penetration. A rigid sleeve surrounds a shank portion of the needle, with the collar member sliding along the outside of the sleeve during penetration. The sleeve lends further lateral support to the needle. The lateral support so provided enables the use of a very thin needle which readily penetrates the drywall and leaves only a tiny pin hole to repair, if necessary.
    • 用于定位隐藏在可撕开构件后方的物体的装置,该物体比物体密度小,包括具有安装在手柄上的细长针的手柄。 隐藏在可穿孔构件后面的密集物体的位置,例如位于干墙后面的螺柱的位置,通过在选定的点处驱动针穿过干式墙壁来指示直到螺栓被撞击。 定位装置优选地包括围绕和包围针的刺穿端的套环构件,其为针的该部分提供横向支撑。 在穿透穿孔部件期间,衣领内设置在手柄内的孔,其中套环相对于孔偏向外侧,以确保针穿透点处的这种横向支撑。 刚性套筒围绕针的柄部分,其中套环构件在穿透期间沿套筒的外部滑动。 套筒向针提供进一步的横向支撑。 如此提供的横向支撑使得能够使用非常细的针,其可以容易地穿过干墙,并且如果需要,仅留下一个微小的针孔来进行修理。

    • A magneto-impedance element with a longitudinal columnar section whose cross section about a longitudinal center axis is either a circle or a polygon inscribed in the circle, and which has a trap region configured to trap a magnetic substance that is formed in a band region extending along at least one of two lines of intersection between a plane containing the center axis and a lateral surface of the longitudinal columnar section and a non-trap region for a magnetic substance that is a region of the lateral surface of the magneto- impedance element excluding the trap region. The magneto-impedance element is used to provide a detection apparatus and a detection method that can easily detect a magnetic substance with high precision.
    • 一种具有纵向柱状截面的磁阻元件,其纵向中心轴线的横截面为圆形或内圆切割的多边形,并且具有陷阱区域,该陷阱区域被配置为捕获形成在带状区域中的磁性物质 沿着包含中心轴的平面和纵向柱状部分的侧表面之间的两条线交点中的至少一条和用于磁性物质的非陷阱区域,该磁性物质是磁阻元件的侧表面的区域,不包括 陷阱区域。 磁阻元件用于提供能够以高精度容易地检测磁性物质的检测装置和检测方法。
