Description
なお、図示しないが、光圧回転体1は、所定の粘度を有する液体である媒質中に配置されており、また、光圧回転体1は集光された光の焦点位置の近傍に引寄せられており、光圧回転体1の上面7よりも若干上方から集光照射されているものとする。
(i)請求項1乃至9のいずれかに記載の光圧回転体の金型(金属だけではなく、シリコンや石英を使用する)の作製には、ミクロンオーダーの精密加工が可能な、例えば、放電加工を利用する。放電加工は特に複雑な加工に適しており、工具や加工物に応力がかからないので高精度である。次に
(ii)プレスあるいは射出成形(インジェクション)などの方法で、(a)PC、PMMAなどの熱可塑性樹脂や、(b)紫外線硬化樹脂を成型する。具体的には、(a)では、素材を加熱状態で加圧する、あるいは加熱シリンダ内でどろどろになった液状の樹脂を高速で金型(モールド)枠内に射出し冷却硬化する、(b)では粘度の低い光硬化樹脂を金型(モールド)で変形し、その後で紫外線を照射して硬化させ、金型(モールド)を離すなどによる。これらの微細加工方は、10nmのパターン解像度をもつナノインプリント技術として、本発明の光圧回転体の製造に有効に利用できるものである。
