気球材料であるポリエチレンフィルムを連続接着するバンドシーラ方式は, 大気球製作には適している。しかし, 一度接着を始めると途中で停止できない構造のため, 限られた空間で大きな気球を製作する装置としては構造上に問題があった。開発した新型ベルトシーラは, 連続接着中でも任意の位置で停止, 開始操作が可能な機能を持ったもので, 製作場所のの広狭によらず, 大きな気球を能率良く製作できる装置とすることができた。, Band-sealer machines, which seal long polyethylene-film gores continuously, are used to produce big plastic balloons. The machines are designed to operate in long factories and can not stop sealing in a middle of long gores. This paper describes a new belt-sealer that we have developed for producing big polyethylene balloons. The machine is designed such that it can stop and re-start in any middle point of sealing. The sealer removes handling difficulties of the usual-type band-sealer and can be operated even in factories with a small area., 資料番号: SA0167036000

This graduate-level textbook gives an introductory overview of the fundamentals of quantum nonlinear optics. Based on the quantum theory of radiation, Quantum Nonlinear Optics incorporates the exciting developments in novel nonlinear responses of materials (plus laser oscillation and superradiance) developed over the past decade. It deals with the organization of radiation field, interaction between electronic system and radiation field, statistics of light, mutual manipulation of light and matter, laser oscillation, dynamics of light, nonlinear optical response, and nonlinear spectroscopy, as well as ultrashort and ultrastrong laser pulse. Also considered are Q-switching, mode locking and pulse compression. Experimental and theoretical aspects are intertwined throughout.
