    • The invention relates to automatic sewing and/or joining of textiles, high polymer materials, leather and metals. The object of the invention is to automate the sewing opertion system, to improve the quality of the seam and to conserve labor. A self-regulating system has to be created. According to the invention, the sewing operation is carried out as a control process, in which the deviation of the produced seam shape from the stored seam shape serves as a control value for the transporting elements of the sewing goods. For this, one or a plurality of detection heads and light emitters are arranged in the area of the seaming point, and are connected to an information processing system. The seam shape initially arising is transformed into storable data, is stored together with other data of the seam, and the seam path arising from automatic sewing is compared with the stored data. Deviations from the desired seam path are at once automatically corrected. The invention may be used in the textile, leather, metal, and plastics industries.
    • 本发明涉及纺织品,高分子材料,皮革和金属的自动缝合和/或接合。 本发明的目的是使缝纫操作系统自动化,提高接缝的质量并节省劳力。 必须创建自我调节系统。 根据本发明,缝制操作作为控制过程进行,其中所生产的接缝形状与所存储的接缝形状的偏差用作缝制货物的传送元件的控制值。 为此,一个或多个检测头和发光体布置在接缝区域中,并连接到信息处理系统。 最初出现的缝形变换为可存储数据,与缝的其他数据一起存储,并将自动缝制产生的缝线路径与存储的数据进行比较。 与所需接缝路径的偏差立即自动校正。 本发明可用于纺织,皮革,金属和塑料工业。

    • According to the state of the art, LC displays are known whose torsion angle is between about 180.degree. and 300.degree.. Such displays exhibit good independence of angle of view of white impression and contrast, but they are not gray scale capable and are not free of hysteresis. For that reason, the invention presents a display (10) whose product of plate separation (d) and anisotropy of the angle of refraction is equal to or greater than 0.45 and smaller than 0.65 .mu.m, whose torsion angle .phi. is between 260.degree. and 360.degree., whose liquid crystal molecules (18) have an approach angle .theta. between 7.degree. and 25.degree., and encompass a liquid crystal material between the substrate plates (11) in which the relationship of the elastic constant K.sub.3 to the elastic constant K.sub.1 is between 1.4 and 0.6. The angular relationships (.beta., .gamma.) of the polarization directions P.u, P.o with the respective orientation direction .eta..u, .eta..o is a function of torsion angle .phi.. An improvement of the contrast relationships is provided, if the relationship between the upper polarization direction P.o and the lower polarization direction P.u is smaller than 90.degree..
    • 根据现有技术,已知LC显示器的扭转角在约180度和300度之间。 这种显示器对白色印象和对比度的视角表现出良好的独立性,但它们不是灰度级的,并且不具有迟滞性。 因此,本发明提供了一种显示器(10),其平板分离(d)的乘积和折射角的各向异性等于或大于0.45并小于0.65μm,其扭转角phi在260°和 360°,其液晶分子(18)的接近角θ在7°和25°之间,并且包围在弹性常数K3与弹性常数K1之间的关系为基础的基板(11)之间的液晶材料 介于1.4和0.6之间。 具有相应的取向方向eta.u的偏振方向P.u,P.o的角度关系(β,γ)等于扭转角phi的函数。 如果上极化方向P.o和下极化方向P.u之间的关系小于90°,​​则提供对比度关系的改善。

    • A method of producing a substrate plate for a liquid crystal cell with black matrix areas in which blackened polymer material is already deposited before the structured areas of photosensitive resist overlying the structured electrode areas are removed. Rather, these structured areas of photosensitive resist are removed only after the blackened polymer material has been hardened.This processing sequence has the advantage that no special alignment processes are needed in order to arrange the black matrix areas accurately between the electrode areas. This alignment is obtained autonomously by virtue of the fact that the electrode areas, even after they have been structured with the help of the photosensitive resist areas, are still covered by these selfsame photosensitive resist areas, thereby ensuring in an ideal manner that only the areas between the electrode areas will be filled with black matrix material and this in such a way as to make them butt directly against the electrode areas, so that the maximum possible surface will be covered by black matrix material.
    • 一种制造具有黑色矩阵区域的液晶单元的衬底板的方法,其中,在除了结构化电极区域的光敏抗蚀剂的结构区域之前,已经沉积黑色聚合物材料。 相反,仅在黑化的聚合物材料已经硬化之后才去除这些感光性抗蚀剂的结构化区域。 该处理顺序的优点在于,为了在电极区域之间准确布置黑矩阵区域,不需要特殊的对准处理。 由于这些电极区域即使在光敏抗蚀剂区域的帮助下被构造之后仍然被这些相同的光敏抗蚀剂区域所覆盖,所以这种排列是自主获得的,从而确保了理想的方式,只有这些区域 在电极区域之间将填充黑色矩阵材料,并以这样的方式将它们直接对接在电极区域上,使得最大可能的表面将被黑色矩阵材料覆盖。
