    • A conventional solid protection device disposed on an exposed side of a cylinder for actuating a working device had a possibility of being permanently deformed by contacting an obstacle so as to be prevented from sliding properly corresponding to the telescopic movement of the hydraulic cylinder. An object of the invention is to provide a hardly deformable protection device. To protect an exposed side of a cylinder for a working device, a protection device includes a guard member and a slide guide into which guard member is telescopically fitted. Slide guide is attached to a cylinder tube, and a tip of guard member is attached to a tip of piston rod. Guard member is a flat plate made of spring steel. A width of guard member is larger than a diameter of the piston rod. Notches are provided on lateral opposite sides of a basic side end of guard member. Sliders are fitted to respective notches. The top of guard member is bent into a roll-shape so as to serve as a pivotal portion.
    • 设置在用于致动工作装置的气缸的暴露侧的常规固体保护装置具有通过接触障碍物而永久变形的可能性,以便防止与液压缸的伸缩运动相适应地滑动。 本发明的目的是提供一种难以变形的保护装置。 为了保护用于工作装置的气缸的暴露侧,保护装置包括保护构件和滑动引导件,防护构件可伸缩地安装在该导向件中。 滑动引导件连接到气缸管,并且保护构件的末端附接到活塞杆的尖端。 保护构件是由弹簧钢制成的平板。 防护件的宽度大于活塞杆的直径。 在保护构件的基本侧端的侧向相对侧设置切口。 滑块适合各自的凹口。 保护构件的顶部弯曲成辊状,以作为枢转部分。

    • This invention relates to a fiber optic polarization controller which controls the polarization direction of the light propagating through an optical fiber by curving a single-mode fiber within an imaginary plane S to generate birefringence on the fiber and by rotating the plane S defined with the thus curved portion. The invention aims to prevent twists of the optical fiber which are caused in rotating the plane S by rotating the fiber in one direction from the plane S simultaneously with the rotation of the plane S and correspondingly to the angle thereof. The optical fiber may be rotated either by utilizing the stability of fiber which is held loosely at a curved portion or by forcibly rotating the curved portion from outside.
    • 本发明涉及一种光纤偏振控制器,其通过在虚拟平面S内弯曲单模光纤来控制通过光纤传播的光的偏振方向,从而在光纤上产生双折射并通过旋转由此限定的平面S 弯曲部分。 本发明旨在防止在与平面S的旋转同时沿着与平面S的旋转同时沿着一个方向在一个方向上旋转光纤而引起的光纤扭曲。 光纤可以通过利用松动地保持在弯曲部分处的纤维的稳定性或通过从外部强制地将弯曲部分旋转来旋转。
