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

关于这一主题的主要研究资源是文成书院（东京）收集的有关明治时代日本电信作品发展的文件。在此基础上，阐明了日本通信事业的发展过程和通信省工程局的组成。在日本，从20世纪00年代到30年代，通信作品的发展过程具有划时代的意义。在这一时期，为了更清晰地通话电信，优秀的技术官僚“松前茂吉”在通信部发明了无主盘绕电缆。更重要的是，我们必须注意到，在这一时期，许多电信基础设备已经国产化。在这些著名的优秀成果的支撑下，当今的终身教育社会已经到来。和其他许多优秀的电信技术官僚，组成了战后的“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.
