    • An optical scanning device for leading a laser beam emitted from a semiconductor laser diode through a collimator lens, an imaging lens, and a cylindrical lens to a plurality of reflecting surfaces of a rotatable polygon mirror, and scanning a surface to be scanned movable in a vertical scanning direction with the laser beam reflected on the reflecting surfaces of the polygon mirror and transmitted through a correcting lens. The optical centers of the semiconductor laser diode, the collimator lens, the cylindrical lens, a return mirror, and the correcting lens are located in a plane containing an axis of rotation of the polygon mirror. The semiconductor laser diode, the collimator lens, and the cylindrical lens are located over an upper surface of the polygon mirror. Accordingly, an optical system can be formed in symmetry with respect to a center axis of an optical path of a horizontal scanning light beam from the polygon mirror without interference of the semiconductor laser diode, etc. with the optical path of the horizontal scanning light beam. Thus, the size and weight of the optical scanning device can be reduced, and the optical characteristics and the productivity of the optical scanning device can be improved.
    • 一种光学扫描装置,用于将从半导体激光二极管发射的激光束通过准直透镜,成像透镜和柱面透镜引导到可旋转多面镜的多个反射表面,并且扫描可扫描的表面, 垂直扫描方向与激光束反射在多面反射镜的反射表面上并透过校正透镜。 半导体激光二极管,准直透镜,柱面透镜,返回镜和校正透镜的光学中心位于包含多面镜的旋转轴的平面中。 半导体激光二极管,准直透镜和柱面透镜位于多面镜的上表面的上方。 因此,光学系统可以相对于来自多面镜的水平扫描光束的光路的中心轴对称地形成,而不会干涉半导体激光二极管等与水平扫描光束的光路 。 因此,可以减小光学扫描装置的尺寸和重量,并且可以提高光学扫描装置的光学特性和生产率。

    • A blood separation composition for use in blood collection tubes. The composition comprises, as a gel-like material that is the main ingredient or the composition, a copolymer of sebacic acid with 2,2-dimethyl-1,3-propanediol and 1,2-propanediol. The separation composition may further comprise a thixotropic agent blended with the copolymer. The copolymer renders the blood separation composition stable and less flowable during storage, allowing it to form a stable partition barrier in each collection tube when centrifuged. The blood cells above the barrier are prevented from remaining within the serum, without any amount of harmful oily substances being released from the separation composition.
    • 用于采血管的血液分离组合物。 该组合物作为主要成分或组合物的凝胶状材料包含癸二酸与2,2-二甲基-1,3-丙二醇和1,2-丙二醇的共聚物。 分离组合物还可以包含与共聚物共混的触变剂。 共聚物使得血液分离组合物在储存期间稳定且流动性差,允许其在离心时在每个收集管中形成稳定的分隔壁。 防止屏障上方的血细胞残留在血清中,没有任何量的有害油性物质从分离组合物中释放出来。
