摘要： An array splice for ribbon-like multi-core optical fibers comprises capillary tubes of ultraviolet-transmitting glass each having an inner diameter slightly larger than the outer diameter of the clad of an optical fiber, each glass capillary tube including tapered portions on the opposite ends thereof for insertion of optical fiber bodies, and a groove formed in the middle upper surface region thereof for discharging bubbles and adhesive agent, and a base including recesses formed in the middle upper surface region thereof for receiving and supporting the lower portions of the tube walls of the glass capillary tubes, and a plurality of front-edged separators each disposed at the opposite ends of the associated receiving and supporting recess. The separators are disposed with approximately the same pitch as that for the capillary tubes. Defined between adjacent separators are optical fiber insertion paths having a width which increases with increasing distances from the opposite ends of each capillary tube.

摘要： The invention relates a halftone phase shift photomask and a blank therefor, which enables the transmittance of a phase shift portion to be varied even after blank or photomask fabrication, can accommodate to a variety of patterns, and can be fabricated on a mass scale. The exposure light transmittance of a halftone phase shift layer is arbitrarily variable within the range of 1% to 50%, inclusive, by exposing the blank or photomask to a high temperature elevated to at least 150.degree. C., to an oxidizing atmosphere, or to a reducing atmosphere at a step that can provided independent of the steps for film-forming or photomask fabrication step. This enables the exposure light transmittance of the halftone phase shift layer to be changed to any desired value after blank or photomask fabrication, and so an optimal halftone phase shift photomask to be obtained depending on the size, area, location, shape, and the like of the transferred pattern.
摘要翻译：本发明涉及一种半色调相移光掩模及其空白处理，即使在空白或光掩模制造之后，相移部分的透射率也能够变化，可以适应各种图案，并且可以大规模制造。半色调相变层的曝光透光率可以在1％至50％的范围内任意变化，包括在内，将空白或光掩模暴露于升高至少150℃的高温至氧化气氛，或在可以独立于成膜或光掩模制造步骤的步骤的步骤中进行还原气氛。这使得半色调相移层的曝光光透射率在空白或光掩模制造之后变为任何期望值，因此根据尺寸，面积，位置，形状等获得最佳半色调相移光掩模的转移模式。

摘要： A chromium blank for forming a black matrix-screen to be used as a color filter for a liquid crystal display is formed by forming at least a first antireflection film, a second antireflection film and a screening film sequentially in that order on one major surface of a transparent substrate. Each of the first and the second antireflection film is a semitransparent film formed of a chromium compound or a chromium mixture, containing chromium as a principal component, and the screening film is formed of chromium, a chromium compound containing chromium as a principal component. The transparent substrate, the first antireflection film, the second antireflection film and the screening film meet an inequality: n.sub.s

摘要： A permanent connector for optical fibers comprises a protective glass tube (2), a capillary tube (1) received therein and eccentrically joined thereto, the two tubes being made of ultraviolet-transmitting glass, and an adhesive-passing groove (1c) formed in the middle portion of the capillary tube (1) and opening on the side opposite to the side where they are joined together. An ultraviolet-curing type adhesive agent is charged into the permanent connector for optical fibers and the ends of optical fibers (3, 4) are inserted thereinto through the opposite ends thereof until the clads (3a, 4a) are butted against each other in the capillary tube (1) while pushing out the adhesive agent and air. And ultraviolet rays are radiated to cure the adhesive agent (6), thereby connecting the optical fibers (3, 4) together.

摘要： An optical fiber fixing element consists of a glass tube having an inner hole for receiving a clad portion of an optical fiber and which is formed at one end with a conical flared portion converging into the inner hole and a recess for receiving a cover portion of the optical fiber thereinto, both the flared portion and the recess being formed concentrically with the glass tube. A method of manufacturing such optical fiber fixing element is also provided which comprises forming an erosion resistant film on an outer surface, other than an end face, of a glass tube having an inner hole, treating the end face of the glass tube with a glass erosive solution to thereby form a flared portion, and grinding the flared portion to thereby form a recess in the flared portion.
