摘要： A method for evaluation of an eddy current testing signal is provided. The method includes the steps of generating a feature amount based on a sample eddy current testing signal obtained by measuring a standard specimen, the feature amount including a feature highly correlated to a secondary factor which is other than a depth of the flaw and which affects the waveform of the signal; generating an evaluation parameter by using the feature amount, the evaluation parameter being a parameter for outputting a value with a sufficiently small error relative to correct answer data on the sample eddy current testing signal; and estimating the depth of a flaw, expressed by an actual measurement eddy current testing signal, by use of the evaluation parameter.

摘要： A method and an apparatus for classifying and recovering the main components of used batteries, particularly, a method and an apparatus by which the batteries are conveyed on a conveyor while an alternating magnetic field of a plurality of frequencies is applied to each and a detection means detects what sort of induced magnetic field has resulted from the eddy current induced in the battery. The orthogonal components in the change of the induced magnetic field are detected; the relationship between these orthogonal components and the frequencies are compared with the database of the same which is previously obtained, and the batteries are sorted according to their classification and size. This method can sort large amounts of used batteries continuously. In this invention, the battery will be drawn down into the detection region either magnetically or mechanically while the stable transport of the battery is achieved. The method and apparatus of the invention enable continuous bulk sorting of batteries, assure a smooth feed, and improve the accuracy with which the induced magnetic field generated in the battery is detected.

摘要： This invention prevents the failure of detection for horizontal and oblique lift-offs in a probe for an eddy current flaw detection test. A plurality of probes are provided, and each probe includes four detection coils. Two adjacent eddy current flaw detecting probes commonly own (share) one of the four coils. The detection coils are connected to a bridge circuit for picking up a flaw signal. The detection coils are adjusted so that interlinkage magnetic fluxes generated inside the detection coils by the eddy current become equal. An excitation coil for inducing the eddy current in a test piece by AC driving can be disposed over the detection coils. The center of the excitation coil is positioned on the center axes of the detection coils. An oscillator for applying an AC current to this excitation coil is connected to the coil.
