    Abstract: A fiber optic device comprised of a pair of bundles of lightconducting optical fibers each having light-receiving and lightemitting opposite end faces. A light-emitting face of one bundle and a light-receiving face of the other bundle are coupled together unsymmetrically with respect to axes of correspondingly interfacially related fibers of the two bundles wherewith light entering the uncoupled light-receiving face of the one bundle at a given numerical aperture will be emitted from the uncoupled light-emitting face of the other bundle at an angular spread of larger numerical aperture than that of the entering light.

    Abstract translation: 一种由一对光导纤维束构成的光纤装置，每个光导纤维光束具有光接收和发光的相对端面。 一束的发光面和另一束的光接收面相对于两束的相应的界面相关的光纤的轴线不对称地耦合在一起，其中光线进入一束的未耦合的光接收面 给定的数值孔径将以比入射光的数值孔径更大的角度扩散从另一个束的未耦合的发光面发射。

    Abstract: The invention relates to an improvement in a method of gas plating the walls of channels of a multi-channeled election amplifying element by thermal decomposition of a metal plating vapor continually directed through said channels which comprises the steps of preheating said plating vapor to nearly its decomposition temperature prior to entrance thereof into said channels of said elements and intermittently heating said element to a temperature at least equal to that of the decomposition temperature of said plating vapor and allowing said element to cool to a temperature below said decomposition temperature during said intervals between said intermittent heating to effect flushing of said residue gases of said vapor in said channels by said continuous flow thereof during said intervals.

    Abstract translation: 本发明涉及通过连续引导通过所述通道的金属电镀蒸气的热分解来对多通道选择放大元件的通道壁进行气体镀敷的方法的改进，其包括以下步骤：将所述电镀蒸气预热到几乎分解 在进入所述元件的所述通道之前的温度，并且间歇地将所述元件加热至至少等于所述电镀蒸气的分解温度的温度，并且允许所述元件在所述电镀蒸气之间的间隔期间冷却到低于所述分解温度的温度 间歇加热以在所述间隔期间通过其所述连续流动来使所述通道中的所述蒸气的所述残余气体冲洗。
