    • A vehicle wiper blade and wiper blade assembly having a longitudinal stiffener mounted on the blade body at an offset angle from the central geometric plane of the blade edge, defined by the neck and wiping edge of the blade. When mounted in the presence of a wind stream flowing over the vehicular windshield, the protruding face surfaces of the stiffener function as an air dam to reduce lift-off effects, or as an airfoil to provide a supplemental pressure directing the wiper blade against the windshield. The proximity of the lower, forward edge of the blade to the windshield serves as an air dam. The upper trailing edge of the blade may be extended to serve as an airfoil. Torque about the wiping edge is avoided by directing the wiper arm pressing force in alignment with the central geometric plane of the blade, and preferably through the neck portion of the blade.
    • 一种车辆刮水片和刮水片组件,其具有以与叶片的颈部和擦拭边缘限定的叶片边缘的中心几何平面偏移的角度安装在叶片本体上的纵向加强件。 当在存在流动在车辆挡风玻璃上的风流的情况下安装时,加强件的突出的表面作为空气坝起作用以减少剥离效果,或者作为翼型件提供将刮水片引导到挡风玻璃上的补充压力 。 叶片的较低的前边缘与挡风玻璃的接近作为空气坝。 叶片的上后缘可以被延伸以用作翼型件。 通过将刮水器臂的按压力与叶片的中心几何平面对齐并且优选地通过叶片的颈部部分来避免围绕擦拭边缘的扭矩。

    • The present invention relates to a method for preparing a GI (graded index) plastic optical fiber preform having a radial refractive index gradient, the refractive index increasing gradually from the outer periphery of the preform toward the center thereof, comprising inserting a 1st plastic tube (inside diameter: d1i, outside diameter: d10) (111) made of a first polymer (refractive index: n1) in a cylinder reactor (inside diameter: d0i, d10≦d0i) and inserting a 2nd plastic tube (inside diameter: d2i, outside diameter d20, d20≦d1i) (112) made of a second polymer (refractive index: n2, n2≧n1) in the 1st plastic tube, the reactor, the 1st and 2nd plastic tubes are positioned coaxially, injecting a precursor of a third polymer (refractive index: n′, n′≧n2) into the 2nd plastic tube, injecting a precursor of a fourth polymer (refractive index: n″, n1≦n″≦n2) into the space between the 1st and 2nd plastic tubes.
