Latest Patents

One of Mori's latest patents is an apparatus for detecting the center of a welded seam. This innovative device first magnetizes a base metal with an alternating flux to cross the welded seam. The resulting leakage flux from the welded seam is detected by at least one flux search element, generating an AC signal. The fundamental harmonic component corresponding to the magnetizing signal is eliminated from the AC signal, and the resulting signal voltage is sampled at a fixed period. This process allows for the detection of the center position of the welded seam based on the sampling results. The apparatus includes a magnetizing coil, flux search elements, and a sampling circuit, which work together to determine the relative positional relation between the flux search element and the center of the welded seam.

Another significant patent by Mori is an eddy current flaw detector that utilizes a pair of parallel resonant circuits. By connecting a negative resistance in parallel to the resonance circuit composed of a coil and condenser, the detecting system enhances sensitivity for flaw detection. This innovation reduces the required degree of amplification of the following amplifier, thereby minimizing the influence of unbalance in the bridge circuit. Additionally, the simplification of the power source for this system can be easily achieved.
