    概要:軽く歪が大きい特徴を有する形状記憶ポリマーをアクチュエータとして使用するための駆動方法を開発した.アクチュエータとして用いるためには2方向の動作が必要であるが,形状記憶効果は1方向性である.そこで加熱・放熱の温度操作で形状記憶効果のみにより2方向性を実現する方法を開発し検証した.(前記研究テーマ3)
  4. ディスク記憶装置の流体振動低減とマイクロ機構の適用に関する基礎研究
    (課題番号:16560233),平成16年度~平成17年度
    研究代表者:今井郷充(分担者なし)
    概要:ヘッドの位置決め振動低減のために,位置決め機構を微小化した場合(マイクロ化含め)に励振力がどのように減少するかを明らかにした.
