Title: Masakatsu Yamazaki: Innovator in Mn-Zn Ferrite Technology
Introduction
Masakatsu Yamazaki is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of materials science, particularly in the development of Mn-Zn ferrites. With a total of 4 patents to his name, Yamazaki's work has had a considerable impact on the industry.
Latest Patents
Yamazaki's latest patents include a method for producing Mn-Zn ferrites. This innovative method involves a three-step sintering process that efficiently produces Mn-Zn ferrites with excellent magnetic properties in a shorter time frame. The first step raises the temperature from room temperature to 600°C over a period of 30 minutes to 5 hours. The second step involves increasing the temperature to the sintering temperature and maintaining it until cooling begins, all within a period shorter than 10 hours. Finally, the cooling step lowers the temperature to 150°C over a period longer than 3 hours, with the total duration of the three steps being less than 20 hours. Additionally, he has developed a low power loss Mn-Zn ferrite, which consists primarily of Fe₂O₃, MnO, and ZnO, along with trace additives. This ferrite is particularly suitable for use as a transformer material in switched mode power supplies.
