The developer of the world's strongest magnet is Tohoku University OB Masato Sagawa "Queen Elizabeth Engineering Award"
―――――――― I ask Professor Sugimoto, Tohoku University
Masato Sagawa (78) of Tohoku University OB = Daido Special Steel Advisor = was selected this month as the "Elizabeth Queen Engineering Award", called the Nobel Prize in the engineering field.Mr. Sagawa's strongest "neodymium magnet" developed in 1982 was evaluated as "groundbreaking technological innovation that brings global benefits to humanity."Professor Satoshi Sugimoto (magnetic material) of the Graduate School of Engineering, Tohoku University, taught me the significance.(Editorial Bureau Content Content Center, Roji Sato)
For everything
-What kind of neodymium magnet is used?
"It was adopted on a personal computer hard disk (HD) and mass -produced in less than three years since the invention. From around 1997, when the Kyoto Protocol (which is an international agreement to prevent global warming), it was around 1997.It has come to be used for everything. It helps to miniaturize and save air conditioners, air conditioners compressors, smartphone speakers, etc., and have no neodymium magnet.
-What are the expected areas that you will use?
"It is indispensable for the realization of a car calibrous society. It is used for a motor and generator of a hybrid vehicle (HV) electric vehicle (HV) electric vehicle (HV) electric vehicle (HV) electric vehicle (HV).EVs get bigger to about trucks. "
"Motors account for about 60 % of domestic power consumption. If 1 % can be reduced in power consumption, energy saving can be saved for one nuclear power plant. Therefore, an efficient high -performance magnet is used.Motors have been adopted in recent years. "
From 2 elements to 3rd elements
-How was it an academic?
"The high -performance magnet one generation ago was composed of two elements, a summarium and a cobalt. It is scientifically valuable that it was made using three elements: neodymium, iron, and boron."
"It is also wonderful that about 70 % of the heavy ingredients are made of iron without using a rare resources cobalt. It is also excellent that the powder can be made and solid.It can be said that it was invented in a valuable form. "
-What is your relationship with Mr. Sagawa?
"I have been talking at the conference since the invention of the neodymium magnet. I jointly studied on a national project for five years from 2007. The neodymium magnet adds a dizzprise of Shigetsu soil so that magnetic force does not fall even at high temperatures. From China.We have developed a technology to reduce the usage of disprocyum, which depends on imports by 40 %, was also informed of this award first. "
Philosophy -oriented philosophy
-What is Sagawa's personality?
"Because I had a hard time when I was young, I encouraged and support young people. It is a ponder type, I do not watch any movies during long flights, and I have been thinking and thinking all the time.That's right. Regarding the research, he has the spirit of "Who is doing it, he's doing it?"
-The University has led the world in magnet research.
"Mr. Sagawa has respected Dr. Kotaro Honda (the first director of the Metal Materials Research Institute, invented the world's strongest magnet" KS Steel "at the time).When the international award was awarded, I was pleased that I was closer to the same position as Honda -sensei. Mr. Sagawa embodies the Tohoku University philosophy of respect for practical studies. "
[Queen Elizabeth In Engineering Award] It was founded in 2012 and has been awarded once every two years from 2013.Until now, researchers such as the Internet, satellite use position (GPS), and light emitting diodes (LEDs) have been selected.From the sixth this year, the award was award, and the prize money was £ 500,000 (about 78 million yen).
