摘要： A detection method and detection device of buried metal which are capable of detecting singular points, in horizontal and vertical directions, of metal tubes, telecommunication cables, and electric power cables, or the like buried in the ground. A magnetic field component of the direction of 3 axes of a XYZ axis is detected by two or more magnetic sensors installed in the detectable direction, and detects a magnetic field induced to buried metal. While carrying out synchronous detection of these magnetic field components and calculating for each amplitude and each phase of a magnetic field component of the direction of 3 axes, image processing is carried out and it is outputted to a display. While calculating for the position of a singular point, a singular point distinguishes whether it is an over-crossing state, it is an under-crossing state, or it is a branched state from these image data.

摘要： A leakage-sound detecting apparatus is provided for efficiently detecting water leakage in a plastic pipe by increasing sensitivity to a low frequency sound component and efficiently reducing stray noise, as well as protecting a piezoelectric element. To this end a detection portion and a pedestal portion are connected through a mechanical resonant member formed of a soft material. A low frequency sound component is amplified by the resonant member, and high frequency components are substantially attenuated. In an alternative arrangement a detection portion and a mechanical resonant member mounted on a pedestal portion are connected through a buffer portion having a buffer member arranged therein. When a shock is applied to the bottom of the pedestal portion, due to the apparatus being dropped for example, the buffer member is compressed, and no overload is applied to a piezoelectric element.
