    • An optical disc apparatus includes a fixed portion having a light source portion and a movable portion that holds an objective lens and moves along a radial direction of an optical disc. The fixed portion includes the light source portion for selectively emitting short and long wavelength laser beams, and a collimator lens for collimating the laser beams. The objective lens includes a positive refractive lens and a diffractive lens structure formed on a surface of the refractive lens.

    • To erase data stored in a flash memory at high speed with simple processing and to improve operation environment, a file stored in the flash memory is managed by small blocks smaller than a rewriting unit, and small blocks are linked to each other so that a file having a size of plural blocks can be constructed. When a file erase command is inputted, an ineffective code is written in an area indicative of effectiveness/ineffectiveness of each block which constructs the file subjected to erasing. Writing an ineffective code is easily realized, without erasing the flash memory, by changing at least one bit of the effective code from “1” to “0”. When the set time comes, blocks storing ineffective codes are organized.

    • In a gas phase olefin polymerization, an olefin is continuously fed to a fluid bed reactor in which a metallocene catalyst is present. At least one compound selected from water, alcohols and ketones is added in a specified amount simultaneously with the feeding of the olefin. Thus, an olefin polymer having a satisfactory drop second count index as defined by the below indicated formula is produced: ##EQU1## wherein t.sub.0 and t respectively represent a flow time measured in the flow test according to ASTM D-1775 of the olefin polymer obtained when none of the water, alcohols and ketones is incorporated in the reactor, and when at least one compound of water, alcohols and ketones is incorporated in the reactor. The flowability of the polymer formed in the reactor is excellent, so that blocking, bridging and the like do not occur during the gas phase polymerization. Thus, it is feasible to stably produce a (co)polymer having excellent particle properties in high yield for a prolonged period of time.

    • A light beam emitted from a laser diode passes through a polarization beam splitter, a movable mirror, a reference prism supported in a pair of rails, a sliding mirror and is incident on a cat's-eye optical system. The light beam reflected in the cat's-eye optical system returns to the polarization beam splitter along an optical path of the incident light beam, is separated by a polarizing separating plane and is directed to a television camera. The front surface of the reference prism is perpendicular to the rails. Thus, the light beam reflected at the front surface of the reference prism is directed to the television camera along an optical path which is inclined relative to the optical path of the incident light beam in accordance with the direction of the rails. Consequently, if the inclination of the movable mirror is adjusted such that the light spots of both of the reflected beams displayed on the monitor coincide, the optical path of the incident light beam is parallel to the rails.
    • 从激光二极管发射的光束通过偏振分束器,可移动反射镜,支撑在一对轨道中的参考棱镜,滑动反射镜并入射到猫眼光学系统。 反射在猫眼光学系统中的光束沿着入射光束的光路返回到偏振分束器,被偏振分离平面分离并被引导到电视摄像机。 参考棱镜的前表面垂直于导轨。 因此,在参考棱镜的前表面处反射的光束沿着相对于入射光束的光路相对于轨道的方向倾斜的光路被引导到电视摄像机。 因此,如果调整可动镜的倾斜度,使得显示在监视器上的两个反射光束的光点重合,则入射光束的光路平行于轨道。
