Latest Patents

Fujimura holds a patent for an "On-line coating adhesion determination apparatus of galvannealed steel sheet, and galvannealed steel sheet manufacturing line." This apparatus includes an X-ray tube that irradiates a galvannealed steel sheet traveling on a transportation line with X-rays. The optical system allows the emitted X-rays to be diffracted, and a detector measures the intensity of the diffracted X-rays. The design ensures that the emitted beam luminance of the X-rays is 20 W/mm or higher, with a width-direction gain of 0.15 or higher. The crystal lattice spacing d may be 1.914 Å, and the energy of the incident X-rays is lower than the excitation energy of Fe-Kα fluorescence X-ray.
