Introduction

Tetsuo Hori is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of permanent magnet materials, holding 2 patents that showcase his innovative approach to enhancing magnetic properties.

Latest Patents

Hori's latest patents include the development of a rare type-earth-cobalt permanent magnet material, specifically R.sub.2 Co.sub.17. This invention focuses on the addition of at least two elements from Nb, V, Ta, and Zr to a ternary alloy of R (rare earth)-Co-Cu. This addition aims to improve the coercive force, residual magnetization, and energy product of the permanent magnets. The new formulation allows for Cu and Fe contents of the alloy to be less than 10% and more than 6%, respectively, which were previously avoided in prior art to prevent reductions in Br and Hc.

Another notable patent by Hori is related to the process for producing permanent magnet materials. This patent also emphasizes the addition of Nb, V, Ta, or Zr to the ternary alloy of R-Co-Cu, further enhancing the magnetic properties while maintaining the specified alloy compositions.
