回転対称殻の英語

回転対称の球殻、円筒、円錐等で構成される内殼、外殻を同軸上に配置し、互いに共通の回転軸上で自由に回転できるようにし、それぞれの表面にスリットを設け、該スリットは２つの内殻、外殻上に互いが交差するように設けられている防塵装置。例文帳に追加

In this dustproof device, an inner shell and an outer shell each composed of a rotationally symmetric spherical shell, cylinder, cone or the like are coaxially disposed such that the inner shell and the outer shell can freely rotate around a rotational axis common to each other, while slits are formed on the respective surfaces of the inner and outer shells such that the slits crosses each other. - 特許庁

外形が長軸と短軸を有し、かつ長軸を回転軸とする回転対称性をもつ、細長い形状であり、外形をなす殻の内部に外形とほぼ相似の空洞が形成されている中空粒子を作製する。例文帳に追加

The hollow particle is produced of which the outer shape is a slender shape having a major axis and a minor axis and having revolution symmetry with the major axis as an axis of revolution, and in which a cavity substantially similar to the outer shape is formed within a shell forming the outer shape. - 特許庁
