Title: The Innovative Contributions of Tetsuhiko Mizoguchi
Introduction
Tetsuhiko Mizoguchi, an esteemed inventor based in Kyoto, Japan, has made significant advancements in the field of magnet technology. With a total of seven patents to his name, Mizoguchi has consistently pushed the boundaries of innovation, particularly in the production of NdFeB (neodymium-iron-boron) magnets, which are known for their high magnetic strength.
Latest Patents
Mizoguchi's latest patents focus on improving the magnetization characteristics of NdFeB system sintered magnets. One such patent presents a unique approach where the median grain size of the crystal grains at a section perpendicular to the c axis is maintained at 4.5 µm or less. This innovation enhances the coercive force while ensuring that the area ratio of smaller crystal grains is minimized to 5% or lower.
Another remarkable creation by Mizoguchi involves a NdFeB system sintered magnet produced via a grain boundary diffusion method. This magnet boasts a high coercive force and an impressive squareness ratio, paired with minimal decrease in the maximum energy product. In this patent, the integration of dysprosium (Dy) and/or terbium (Tb) into the base material yields a superior magnetic performance through controlled diffusion techniques.
