摘要： A lens drive mechanism for an optical disc player includes a movable unit including an objective lens for focusing a coherent beam of light on an optical disc, a lens holder carrying the objective lens, focusing and tracking coils secured to opposite portions of a periphery of the lens holder. The lens drive mechanism also includes permanent magnets and yokes, and a plurality of support members connected at one end to the periphery of the lens holder and at the opposite end to a support fixture for supporting the movable unit for movement in focusing and tracking directions substantially perpendicular to each other. A upper set of the support members has a spring constant different from that of a lower set of the support members, and the product of the spring constant of the upper set of the support members multiplied by a distance from the center of gravity of the movable unit to a position of securement of the upper set of the support members is chosen to be equal to the product of the spring constant of the lower set of the support members multiplied by a distance from the center of gravity of the movable unit to a position of securement of the lower set of the support members.
摘要翻译：用于光盘播放器的透镜驱动机构包括：可移动单元，包括用于将相干光束聚焦在光盘上的物镜，承载物镜的透镜架，固定到所述物镜周边的相对部分的聚焦和跟踪线圈镜头座透镜驱动机构还包括永磁体和轭，以及多个支撑构件，其一端连接到透镜保持器的周边，并且在相对端连接到支撑固定件，用于支撑可移动单元以基本上在聚焦和跟踪方向上移动彼此垂直。上一组支撑构件具有与下一组支撑构件的弹簧常数不同的弹簧常数，并且上部支撑构件的弹簧常数乘以距离可移动的重心的距离的乘积单元到上部支撑构件的固定位置被选择为等于下部支撑构件的弹簧常数乘以距离可移动单元的重心的距离乘以位置固定下一组支撑构件。

摘要： A flat tablet case (A) is assembled by joining together a bottom half case (30) having the shape of a rectangular tray and a top half case (10) having the shape of a rectangular tray. A plurality of studs (21 to 25) are formed on the inner surface of the top half case (10), and a plurality of sockets (41 to 45) are formed on the inner surface the bottom half case (30). A hinged cap (50) is formed integrally with the bottom half case (30) in a section of the side wall (31) excluding corners. The hinged cap (50) is provided on its opposite side surfaces with projections (53, 54) which are engaged with and disengaged from cap holding structures (35, 36) formed on the bottom half case (30).
