Abstract: The present invention relates to a composition, preferably a cosmetic composition, and more preferably a skin cosmetic composition, comprising: (a) at least one complex, comprising at least one cationic polymer and at least one anionic polymer, at least one cationic polymer and at least one amphoteric polymer, at least one anionic polymer and at least one amphoteric polymer, or at least one amphoteric polymer, and at least one non-polymeric acid having two or more pKa values or salt(s) thereof or at least one non-polymeric base having two or more pKb values or salt(s) thereof; (b) at least one oil; and (c) water, wherein the cationic polymer comprises at least one cationic cellulose polymer with at least one fatty chain comprising at least 10 carbon atoms, and if the (a) complex comprises at least one anionic polymer and at least one amphoteric polymer, or at least one amphoteric polymer, the (a) complex further comprises at least one cationic cellulose polymer with at least one fatty chain comprising at leas

Abstract: Pick-up and placement apparatus including an arm that executes pick-up and placement motions and an arm drive mechanism. The drive mechanism comprising a driven rotating member having an appointed range of rotation, a swiveling member slidably attached to the rotating member and swiveling in an appointed range of rotation by normal and reverse rotations of the rotating member, a connection portion directly or indirectly linked with the arm, a retaining member applying a retaining force to retain the swiveling member at an appointed position in a radial direction with respect to the rotating member while slidably retaining the swiveling member, and an apparatus regulating and guiding said connection portion to linearly move the connection portion by directly or indirectly regulating the swiveling member in the vicinity of both ends of in the range of rotation.

Abstract: Pick-up and placement apparatus including an arm that executes pick-up and placement motions and a drive mechanism that drives said arm. The drive mechanism comprising a rotating member normally or reversely driven and rotated in an appointed range of rotation, a swiveling member slidably attached to the rotating member in the radial direction and normally or reversely swiveling in an appointed range of rotation by normal and reverse rotations of the rotating member, being provided with a connection portion directly or indirectly linked with the arm, a retaining means applying a retaining forces to retain the swiveling member at an appointed position in the radial direction with respect to the rotating member while slidably retaining the swiveling member, and a means for regulating and guiding said connection portion to linearly move the connection portion by directly or indirectly regulating the swiveling member in the vicinity of both ends of in the range of rotation.
