Latest Patents

Yoshida's most recent patents reflect his commitment to enhancing electrical conductivity and insulation. One notable invention is a method for manufacturing a stranded conductor for an electrical power cable. This method features a process for forming cupric oxide films with a thickness ranging from 0.3 µm to 3 µm. This is achieved by passing an uninsulated stranded conductor—comprised of several copper strands—through an oxidizing liquid, allowing the formation of cupric oxide films on the strands. This stranding technique incorporates a wave-like curvature to create gaps that facilitate the penetration of the oxidizing liquid, leading to a reliable and efficient conductor.

Additionally, Yoshida has developed a laminated insulation paper designed with two cellulose layers separated by a plastic layer. This innovative paper includes through holes in the plastic layer, which enable direct contact between the cellulose layers, enhancing physical and thermal properties. The fabrication of this insulation paper involves pressing heated, rounded pins into one cellulose layer, ensuring effective contact between the cellulose layers through the holes made in the plastic layer.
