Title: The Innovative Contributions of Makoto Ogasawara
Introduction
Makoto Ogasawara is a notable inventor based in Shiga, Japan. He has made significant contributions to the field of magnetic materials, particularly through his innovative patents. With a total of 3 patents to his name, Ogasawara continues to push the boundaries of technology in his area of expertise.
Latest Patents
Ogasawara's latest patents include the development of acicular ferromagnetic iron oxide particles and a process for producing them. These acicular berthollide particles are characterized by their crystalline structure, expressed by the formula FeOx (1.33 ≤ x < 1.5), and are modified with a specific amount of zinc ions. The process for producing these particles involves oxidizing acicular magnetic iron oxide particles, which are initially expressed by the formula FeOx (1.0 < x < 1.33) and also modified with zinc ions. This innovative method includes several steps, such as heating and dehydrating acicular hydrous iron oxide particles containing zinc, reducing them, and heating under specific conditions.
Another significant patent involves a process for producing magnetic iron oxide particles for magnetic recording. This process entails heat-treating magnetic iron oxide particles, such as magnetite, berthollide, or maghemite, in the presence of a zinc component at temperatures ranging from 400°C to 700°C. The resulting magnetic iron oxide particles exhibit improved saturation magnetization due to the doping of zinc ions.
