Title: Hiroshi Kotaki: Innovator in Superconducting Wire Technology
Introduction
Hiroshi Kotaki is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of superconducting wire technology, holding a total of 6 patents. His innovative work focuses on improving the manufacturing processes of MgB superconducting wires, which have important applications in various industries.
Latest Patents
Kotaki's latest patents include a method for producing MGB2 superconducting wire material and a production method for MgB superconducting wire rod superconducting coils and MRI applications. The first patent aims to provide a method for achieving sufficient deformation in precursor particles, even when using a soft high-purity metal for the outer layer material during mechanical milling. This method involves subjecting magnesium powder and boron powder to a shock that is insufficient for MgB to be clearly produced, resulting in precursor particles with boron particles dispersed inside a magnesium matrix. The process includes filling a metal tub with these precursor particles, processing the metal tube to form a wire, and heat-treating the wire to synthesize the MgB, with a portion of the wire-drawing step including swaging.
The second patent focuses on increasing the critical current density of wire rods with symmetrical shapes, such as round or square wires, by utilizing a mechanical milling method. This production method involves preparing a powder by adding a solid organic compound to magnesium and boron powders, applying an impact to create a mixture, filling a metal tube with this mixture, elongating the tube, and heat-treating it to synthesize MgB.
