Losses, Efficiency and Thermal Behavior of the Synchronous Motors with Different PM Materials
Communications, 2013 The paper deals with losses, efficiency and thermal behavior of the synchronous machines with different permanent magnet (PM) materials. Three PMSM are presented in this paper: First, the PMSM with NdFeB PM, which is really constructed. Second, the NdFeB

Dynamical thermal behavior and thermal self-stability of microcavities [PDF]
Optics Express, 2004 As stability and continuous operation are important for almost any use of a microcavity, we demonstrate here experimentally and theoretically a self-stable equilibrium solution for a pump-microcavity system. In this stable equilibrium, intensity- and wavelength-perturbations cause a small thermal resonant-drift that is enough to compensate for the ...

Studies on the Thermal Behavior of Polyamides
Kobunshi Kagaku, 1970 ポリヘキサメチレンアジパミドに含まれるオリゴアミドの熱酸化における挙動について研究した。エタノールによりオリゴアミドを抽出除去したポリアミド試料と抽出前の試料の熱酸化における分子量の変化を比較した結果, 低分子量のオリゴマーは分子量低下の原因とはなっていないことがわかった。さらに種々の環状オリゴアミド, 直鎖状ナリゴアミドおよびオリゴアミド混合物の熱酸化について検討し, ポリヘキサメチレンアジパミドと比較した。また熱酸化において紫外部290mμに顕著な特性吸収を示すオリゴアミド混合物 (mp254～256℃) が, ポリヘキサメチレンアジパミドから抽出分離された。
