    • An improved yarn feeder for knitting machines includes a frame, a feeding reel, a brake, a press block, a pulley, a holder, a transmission spindle and a yarn guide. The feeding reel includes a driven wheel which has a top flange with a center opening and a plurality of equally spaced rods extending downward from bottom surface of the top flange, and a driving wheel which has spoke like ribs each has a slot opening at a free end thereof for engaging with an elongated bar at a lower portion which has a “8” shaped crosssection. The driving wheel may engage with the driven wheel through the center opening with the top end of the elongated bar engaged with a cavity formed in the bottom side of the top flange between a pair of adjacent rods. The feeding reel and the yarn feeder may be made with greater precision at a lower cost than conventional yarn feeder.
    • 用于针织机的改进的喂纱机包括框架,馈送卷轴,制动器,压块,滑轮,保持器,传动主轴和导纱器。 馈送卷轴包括从动轮,该从动轮具有带有中心开口的顶部凸缘和从顶部凸缘的底部表面向下延伸的多个等间距的杆,以及具有辐条状肋条的驱动轮, 其端部与具有“8”形横截面的下部的细长杆接合。 驱动轮可以通过中心开口与从动轮接合,细长杆的顶端与在一对相邻的杆之间形成在顶部凸缘的底侧中的空腔接合。 馈送卷轴和喂纱器可以以比传统喂纱机更低的成本更高的精度制成。

    • A underlayer process for high O.sub.3 /TEOS interlayer dielectric deposition is disclosed. First, a layer of metal pattern is defined on a semiconductor substrate, then a layer of dielectric underlayer is deposited, next, a high O.sub.3 /TEOS interlayer dielectric is formed to achieve planarization. The key point of this process is to apply materials with higher refraction index than conventional PE-TEOS for forming interlayer dielectric underlayer. The mentioned material can be PE-SiH.sub.4 with a constant or decreasing refraction index with the distance from the semiconductor substrate. The underlayer can also be bi-layer structure consisting of high refraction index bottom layer and low refraction index surface layer. This invention can effectively suppress the problem caused from high surface sensitivity of O.sub.3 /TEOS, and improve the quality of interlayer dielectric planarization process dramatically.
    • 公开了一种用于高O 3 / TEOS层间电介质沉积的底层工艺。 首先,在半导体衬底上限定一层金属图案,然后沉积一层电介质底层,接着形成高O 3 / TEOS层间电介质以实现平坦化。 该方法的关键在于应用具有比常规PE-TEOS更高的折射率的材料以形成层间电介质底层。 所提到的材料可以是具有恒定或降低折射率的距离与半导体衬底的距离的PE-SiH4。 底层也可以是由高折射率底层和低折射率表面层组成的双层结构。 本发明可以有效地抑制由O3 / TEOS的高表面灵敏度引起的问题,并显着提高层间介质平坦化工艺的质量。
