摘要： A lightguide which guides light from at least one side end plane and includes a plurality of approximately trapezoidal protrusions whose apex edge in the cross section perpendicular to the axis of a linear light source has a partially straight section. The approximately trapezoidal protrusions are arranged on the rear surface of the lightguide, opposing a light emitting surface. The approximately trapezoidal protrusions are arranged in a pattern of specks, solid lines, or broken lines. The pattern has a low area density in a region neighboring the at least one side end plane and at a high area density in a region removed from the at least one side end plane such that the luminance distribution of the light emitted from the light emitting surface is approximately uniform. Preferably, the approximately trapezoidal protrusions have, in the same cross section, two rounded corners, and the roughness of the surface that includes the apex edge of the protrusions, the roughness of the rear surface excluding the protrusions, is less than 0.2 &mgr;m, the ratio of the height H to the width W of the approximately trapezoidal protrusions in the same cross-section be 0.1≦H/W≦0.6, and the width W is 20 &mgr;m≦W≦200 &mgr;m.

摘要翻译： 导光体，其从至少一个侧端平面引导光，并且包括多个大致梯形的突起，其在与线性光源的轴线垂直的横截面中的顶点具有部分直的部分。 近似梯形的突起布置在光导的后表面上，与发光表面相对。 大致梯形突起以斑点，实线或虚线的图案排列。 该图案在与至少一个侧端面相邻的区域中具有低面积密度，并且在从至少一个侧端面去除的区域中具有高面积密度，使得从发光表面发射的光的亮度分布 大致均匀。 优选地，大致梯形突起在相同的横截面中具有两个圆角，并且包括突起的顶点的表面的粗糙度，除突起之外的后表面的粗糙度小于0.2μm， 相同横截面中大致梯形突起的高度H与宽度W的比值为0.1 <= H / W <= 0.6，宽度W为20μm<= W <=200μm。

摘要： A pressure-sensitively adhering multilayer medicinal preparation comprises a pressure-sensitively adhering macromolecular substance layer and a polymer layer adjacent thereto and the drug and adjuvant incorporated in said preparation each can migrate from the layer of its original incorporation into the other, said adjuvant being capable of increasing absorption of the drug. In such preparation, the drug amount per unit volume can be increased.
