    • An optical device of this invention is such that complicated adjustment of the arrangement is not needed unlike a conventional optical device for outputting light having a frequency different from that of the input light by means of a nonlinear optical crystal. Electrodes (12A and 12B) for Q-switching, electrodes (9A and 9B) for phase adjustment and a periodical domain inversion portion (15) are disposed at predetermined positions in path (2) inside an optical crystal body (1) having nonlinear optical properties, electro-optical properties and laser activity. Oscillation light (P1) is produced by inputting light (P0) given from the input side (3), and output light (P2) having a frequency different from the frequency of the input light (P0) is outputted from the output side (4) by the nonlinear optical property and by the generation of harmonic or by optical parametric oscillation by use of the periodical domain inversion portion (15). The refractive index of the part of nonlinear crystal body (1) between the phase adjustment electrodes (9A and 9B) is changed by changing the voltage between the electrodes (9A and 9B), and the frequency of resonance over the full length (Lt) of the path (2) is thus adjusted. The Q-switching of oscillation light (P) is conducted by changing the refractive index of an oblique crossing portion of the oblique side (G) of the electrode (12A) and the path (2) by changing the voltage between the Q switch electrodes (12A and 12B).

    • The flexible screw in accordance with the present invention is equipped with a flexible rod and a cord disposed helically on the rod. The screw can be arranged not only in a linear transfer line but also in a curve transfer line. Therefore, it is possible to make container transfer smooth and simplify the construction of a container transfer apparatus, thereby reducing the installation cost. It can also reduce wear of the pipe in the transfer of powder or granules. A container transfer apparatus of the present invention includes an arrangement in which the screws described above, or the screw and a guide, are spaced apart in parallel to transfer containers held between them by rotating the screw. The container transfer thus can be made smoothly even in a curve line. Moreover, the maintenance cost of the screws can be reduced and wear of rails can be limited considerably, as well. The transfer apparatus for powder and granules in accordance with the present invention can reduce wear of the pipe.
    • 根据本发明的柔性螺钉装备有柔性杆和螺旋地设置在杆上的绳索。 螺钉不仅可以布置在线性传输线中,而且可以布置在曲线传输线中。 因此,能够容易地进行容器搬送,简化容器搬送装置的结构,能够降低安装成本。 它还可以减少管道在粉末或颗粒转移过程中的磨损。 本发明的容器传送装置包括一种装置,其中通过旋转螺钉,上述螺钉或螺钉和导向件平行地分开保持在它们之间的容器。 因此,即使在曲线中也能够容易地进行容器搬送。 此外,可以减少螺钉的维护成本,同时可以大大限制钢轨的磨损。 根据本发明的用于粉末和颗粒的转移装置可以减少管的磨损。
