    • An apparatus for achieving the return of a chain to a rear derailleur tension pulley more easily by means of pedaling action when the chain falls off from the tension pulley is provided. The rear derailleur is equipped with a base component, a link mechanism, a movable component, Outer Plate 20, Inner Plate 21, Guide Pulley 22, Tension Pulley 23, and Chain Return Section 32. The base component is a component which is mounted on the frame. The link mechanism is a mechanism of which one end is mounted on the base component. The movable component is a component which is mounted on the other end of the link mechanism, and which can be relatively displaced from the base component. The outer plate is a component which is mounted on the movable component so as to undulate like a see-saw. The inner plate is a component which is installed so as to face the outer plate. The guide pulley is a pulley which is mounted onto a portion on one edge of the plates, between the plates, so as to freely rotate and move in the axial direction, and which can be engaged with the chain. The tension pulley is a pulley which can be engaged with the chain, and is mounted onto a portion on the other edge of the plates, between the plates, so as to freely rotate. The chain return section is installed at a position on the inner plate which is proximal to the position at which the tension pulley is mounted, in a manner so that the clearance from the chain at this position is narrower as compared to the clearance at other positions.
    • 提供一种用于当链条从张力滑轮脱落时,通过踩踏动作更容易地将链条返回到后拨链器张紧轮的装置。 后拨链器配备有基座部件,连杆机构,可动部件,外板20,内板21,导向皮带轮22,张紧滑轮23和链条返回部件32。 基座部件是安装在框架上的部件。 连杆机构是其一端安装在基座部件上的机构。 可移动部件是安装在连杆机构的另一端上并且可以相对于基部部件移位的部件。 外板是安装在可移动部件上的部件,以便像跷跷板那样起伏。 内板是以与外板相对的方式安装的部件。 引导轮是安装在板的一个边缘上的部分之间的滑轮,以便在轴向方向上自由旋转并且可以与链条接合。 张力滑轮是可以与链条接合并且被安装在板之间的另一边缘上的部分之间的滑轮,以便自由旋转。 链条返回部分安装在内板上靠近安装张紧轮的位置的位置处,使得与该其它位置处的间隙相比,该位置处的链条的间隙较窄 。

    • A laser system with a solid state laser medium, having a broad oscillation spectrum with improved absorption efficiency of the laser medium for excitation light. The system includes: a resonator; a solid state laser medium, disposed in the resonator, having optical anisotropy; and an excitation unit for inputting excitation light to the solid state laser medium. The oscillation light is linear polarization light polarized in the direction substantially parallel to a first crystal axis of the solid state laser medium, and the excitation unit linearly polarizes the excitation light, and inputs to the solid state laser medium, with the polarization direction of the excitation light in a direction crossing the first crystal axis. In the solid state laser medium, an absorption coefficient for the excitation light in the polarization direction thereof is greater than an absorption coefficient for the excitation light in the first axis direction.
    • 一种具有固体激光介质的激光系统,具有宽的振荡光谱,激发光的激光介质的吸收效率得到改善。 该系统包括:谐振器; 固态激光介质,设置在谐振器中,具有光学各向异性; 以及用于将激发光输入到固态激光介质的激励单元。 振荡光是在与固体激光介质的第一晶体轴基本平行的方向上偏振的线偏振光,激发单元使激发光线性偏振,并且以固体激光介质的偏振方向输入到固态激光介质 沿与第一晶轴相交的方向的激发光。 在固态激光介质中,其偏振方向上的激发光的吸收系数大于第一轴方向上的激发光的吸收系数。
