Abstract
【解決手段】磁気材料のアレイを移動、配置及び整列させる装置は、アレイに組み合わされる固定具であって、前記アレイに対応する複数の特定可能な位置を有する固定具と、前記固定具が組み合わされる前記アレイに対応する前記特定可能な位置にて前記固定具に付着される複数の磁石と、を有し、前記固定具が前記アレイに組み合わされた場合に、前記磁石は、前記固定具の表面上に付着され、前記磁石によって生成される磁場は、前記アレイの少なくとも一部分に広がる、ことを特徴とする。
【選択図】図25A
Description
・デバイスの熱放散時定数(thermal dissipation time constant)
・混合時定数
・反応時間
の3つの時定数を考えると、「低速」混合は、反応時間と熱放散時定数の両方より大きいか、またはそれらと同程度の時定数で混合することと理解できる点に注意されたい。このような場合、熱は発生時と略同じペースで損失し、比較的強力な反応だけが検出される。混合速度を上昇させるために本願で説明するコンセプトを利用することにより、サーミスタが感知する温度上昇がより急峻で高くなり、感度が改善される。
