    摘要： A coating fault locating technique transmits a base electric signal from a power source to a buried metal pipe. A location of a coating fault in the buried pipe is detected by detecting a gradient of a changing magnetic field between two points spaced along the buried pipe. The gradient is detected based upon the output differential of at least one pair of search coils. The gradient is caused by a leakage of current that occurs at the coating fault. In particular, the at least one pair of search coils are provided in a mobile unit that is located above ground. The at least one pair of search coils are spaced apart from one another and have their axes arranged so as to have a low sensitivity to a magnetic field generated by the base electric signal running through the buried pipe. The at least one pair of coils are spaced apart from each other such that a line drawn between midpoints of the search coils' axes crosses a plane normal to the axis of the buried pipe. For example, the at least one pair of search coils are spaced from each other horizontally, with each coil arranged with its axis extending in a vertical plane. The data detected by the search coils in the mobile unit can be transmitted to a GPS system, which then generates a map identifying the locations of any detected coating faults.

    摘要翻译： 涂层故障定位技术将基本电信号从电源传输到埋地金属管。 通过检测沿着埋管隔开的两个点之间的变化的磁场的梯度来检测埋管中的涂层故障的位置。 基于至少一对搜索线圈的输出差分来检测梯度。 梯度是由在涂层故障时发生的电流泄漏引起的。 特别地，至少一对搜索线圈设置在位于地面上方的移动单元中。 至少一对搜索线圈彼此间隔开，并且其轴线布置成对由穿过埋管的基本电信号产生的磁场具有低灵敏度。 至少一对线圈彼此间隔开，使得在搜索线圈的轴线的中点之间绘制的线与垂直于埋管的轴线的平面交叉。 例如，至少一对搜索线圈水平地彼此间隔开，每个线圈以其轴线在垂直平面内延伸。 由移动单元中的搜索线圈检测的数据可以被发送到GPS系统，GPS系统然后生成识别任何检测到的涂层故障的位置的地图。

    摘要： An electromagnetic pump comprising fluid operation chambers for discharging fluid to the outside; and electromagnet connected to an AC power source device for polarity switching for every half cycle of AC when energized; a permanent magent which moves together with the electromagnets; and a reciprocative shaft holding the permanent magnet, which reciprocates in the shaft direction when the electromagnet is energized. The width of a securement portion for the permanent magnet of the reciprocative shaft is relatively narrow compared to the other portions, and the permanent magnet consists of a pair of permanent magnet pieces bonded together by sandwiching the securement portion therebetween. The electromagnetic pump further comprises a fluid operation member for expanding or contracting the volume in the fluid operation chamber by the reciprocation movement of the reciprocative shaft so as to guide fluid out.
