Latest Patents

Fukui's latest patents include an "Inductor with Plurality of Magnet Pieces in Air Gap." This invention features a gap in the magnetic circuit of an iron core inductor, where multiple small permanent magnet pieces are strategically placed. The magnetizing directions of these pieces are arranged side by side. When D.C. and A.C. overlapping currents flow through the inductor, the D.C. magnetic field is offset, resulting in a high inductance value. Additionally, the small size of the permanent magnet pieces minimizes eddy currents and heat production. Another significant patent is for an "Inductor" that includes a coil member wound on closed magnetic circuits made of soft magnetic material. This design incorporates a magnetic gap and a permanent magnet to provide magnetic bias, enhancing the inductor's performance in circuits with superimposed D.C. and A.C. currents.
