HEE-07-13 レーザーの黎明とその後の発展の一側面
The Invention and the Development of Lasers

The realization of the first laser action was performed by T.H.Maiman using optically pumped ruby rods in 1960. Lasers were resulted from masers extending frequency of emission of electromagnetic waves by the factor 104 or so. It is described how this extension achieved overcoming difficulty. The brief description about development of solid state lasers as well. The initiative success and successive improvement of semiconductor lasers are shortly described.
HEE-07-14 撮像管の歴史とデザイン
A Breif History of Television Camera Tubes and the Saticon

The development of the iconoscope camera tube made television broadcasting possible. The image orthicon permitted studio productions with a reasonably comfortable light level of 200 foot-candles and permitted mobile field operations with existing ambient light levels. The problems encountered in colour cameras with image orthicon were overcome by a new tube of the vidicon family. The Plumbicon was developed by Philips and the Saticon was developed by NHK and Hitachi. The first part of the paper describes a breif history of television camera tubes. The second part of the paper concentrates on some of the more interesting features of the Saticon.
HEE-07-15 移動通信・携帯電話技術発展の歴史と課題
History and issue of technological development
in Mobile communications/Portable telephone

This report is the result of an investigation of 100-year history of a basis for today's portable phones, technological development process, the systematic survey of technology (the interaction of technological development with society, culture, economy), advantage of Japan's unique technologies, and describe the pertinent issues and considerations. What really matters is the technology development for a "self-willed ubiquitous communication system and terminal" which is usable by anybody without any restrictions, oriented for human nature, easy to use, safe and untroubled.
HEE-07-16 日本におけるパラメトロン計算機の開発
−MUSASINO-1号50周年を記念して−
Development of Parametorn Computers in Japan

Parametron is a logic element that Eiichi Goto invented in 1954 in Hidetoshi Takahashi's laboratory in the department of Physics at the University of Tokyo. It consists of magnetic cores and a capacitor and uses the parametron excitation phenomenon for the logic operation. Zen-iti Kiyasu, Saburo Muroga and Kensuke Takashima of Electrical Communication Laboratory of Nippon Telegraph and Telephone Public Corporation (NTT) built MUSASINO-1, the first parametron computer in the world, in March 1957. Takahashi Laboratory of the University of Tokyo completed a parametron computer PC-1 in 1958. Later commercial parametron computers were build and shipped by Hitachi, NEC, Fujitsu and other manufacturers.
