Title: The Innovations of Sang-Im Yoo
Introduction
Sang-Im Yoo is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of superconductivity, holding a total of four patents. His work focuses on developing high-performance superconductive materials that have the potential to revolutionize various industries.
Latest Patents
One of his latest patents is titled "Oxide superconductor and method of producing same." This invention describes a high critical temperature and high critical current density superconductor that contains a matrix phase of a metal oxide. The formula for this matrix phase is RE.sup.1 Ba.sub.2 Cu.sub.3 O.sub.p, where RE.sup.1 can be La, Nd, Sm, Eu, or Gd, and p ranges from 6.8 to 7.2. The invention also includes a first dispersed phase and a second dispersed phase of metal oxides, which are integrated into the matrix. The superconductor can be prepared by cooling a partial melt at specific temperatures and cooling rates.
Another notable patent is for "Superconductive composite materials." This composite material consists of multiple sections, each containing a bulk of a superconductive metal oxide of RE--Ba--Cu--O. Each section has pinning centers that can trap a magnetic field, and the superconductive current density varies between sections. The composite can be produced by assembling preformed sections or by growing crystals on one of the sections.
