Japanese English education has focused mainly on teaching passive skills such as reading and listening, whereas actual business activities in society require active skills such as writing and speaking in addition to the passive skills. This educational situation is estimated to be a reason Japanese engineers are less confident in writing and speaking than in reading and listening. This paper focuses on details of the English Technical Writing Test provided by the Japan Society of Technical Communication and emphasizes the importance of the active skills, mainly focusing on what skills should be taught in the future and how to develop these skills. This paper also stresses the necessity of learning rhetoric-related skills, concept of information words, as well as paragraph reading and writing skills based on the concept of the 3Cs (Correct, Clear, and Concise) as a means to develop technical writing skills for engineers.

音導型スピーカに対し、ディジタル信号処理を適用し、スピーカユニット前面に配正された音響管で生じる音響共振の影響を取り除く再生方式について検討を行った。ディジタル信号処理では、音導型スピーカの音圧周波数特性と位相周波数特性の逆特性を実現するFIR型ディジタルフィルタを構成し、入力信号の補正を行う。その結果、ディジタルフィルタを含む総合再生特性は音圧周波数特性がほほ平坦で、位相周波数特性が補正前と比較し大幅に改善された。さらに不要な残事成分の再生も抑制することができた。
