中国磁性材料考察团于一九七五年六月二十四日至七月二十五日,在日本参观访问了二十八个单位。其中有东京电气化学、富士电气化学、日立金属、住友特殊金属、日立麦克塞尔、松下通信、松下电气、富士通等公司所属的磁性材料器件工厂或车间。参观的研究所有:理化学研究所、通产省电子技术综合研究所、日本广播协会综合技术研究所、日立制作所中央研究所、日本电气中央研究所。还参观了东京大学、东京工业大学、东北大学、大阪大学、早稻田大学、庆应大学、京都大学、广岛大学中部分磁学、磁性材料与器件的研究工作。这些单位对我们的态度一般都较友好,有些还是相当热情的。这体现了毛主席的革命外交路线的胜利。通过这次考察使我们了解到日本磁性材料器件生产和科研的概况,看到一些较为先进的工艺和设备。当然由于资本主义的本性,在技术上对我们开放是有限的,同时由于我们考察时间不长,了解不深,水平不高,整理出的这分材料一定有不准确和错误的地方,因此,仅供同志们参考。
The Chinese magnetic material delegation visited 28 units in Japan from June 24 to July 25, Among them, Tokyo Electrochemistry, Fuji Electrochemical, Hitachi Metals, Sumitomo Metal, Hitachi Maxell, Matsushita Telecom, Matsushita Electric, Fujitsu and other companies belong to the magnetic material plant or workshop. Visiting research institutes include: Institute of Physical and Chemical Research, Institute of Electronics Technology of Japan’s Ministry of International Trade and Industry, Institute of General Technology of Japan Broadcasting Association, Central Research Institute of Hitachi Ltd., Central Research Institute of Japan Electric. Also visited the Tokyo University, Tokyo Institute of Technology, Northeastern University, Osaka University, Waseda University, Keio University, Kyoto University, Hiroshima University in part of the magnetic, magnetic materials and devices research. The attitude of these units to us is generally more friendly, and some are quite enthusiastic. This shows the victory of Chairman Mao’s revolutionary diplomatic line. Through this study, we have made an overview of the production and research of Japan’s magnetic material devices and have seen some of the more advanced processes and equipment. Of course, because of the nature of capitalism, there are limited technical openness to us. In the meantime, because of the short period of time we have not studied, the level of understanding is not high, and the sorted materials have some inaccuracies and mistakes. Therefore, Only for comrades reference.
