Scientific & Technological History of The Engineering Bureau of The Ministory of Communications - Process of the development of technical foundation for the life-long education society

本主题的主要研究资源是东京文世书院收集的有关明治以来日本电信事业发展的文献。在此基础上，阐明了日本电信事业的发展历程和通信部工程局的构成。日本电信事业的发展经历了20世纪20年代至30年代的划时代时期。在此期间，通信部优秀的技术官僚松前茂吉发明了用于更清晰通话通信的无主线圈电缆。更重要的是，我们必须注意到，在这一时期，许多电信的基础设备已经国产化。今天的终身教育社会，正是在这些著名的、优秀的成果的支撑下，才得以出现。和其他许多优秀的电信技术官僚，在战后的日子里组成了“电子国家日本”。

Main study resources on this theme are the Bunsei Shoin (in Tokyo)'s collection of documents about the development of telecommunication works in Japan from Meiji era. Basing these considarable documents, the developmental process of the telecommunication works in Japan and the constitution of engineering bureau of the Ministory of Communications had been clarified. In Japan, the process of development of telecommunication works had the epoch making period from 1900's to 1930's. In this period, unlording coiled cable for more clear talking telecommunication, was invented by the excellent technical bureaucrat "Shigeyoshi Matsumae" in the Ministory of Communications. And still more, we must pay attention that in this period many foundamental devices of telecommunications have been domestically produced. Today's life-long education society, supporting by these famous and excellent achievements, have been apearing. And many other excellent technical bureaucrats of telecommunication, had made up "the electronic nation Japan" in the post war days.
