摘要： PURPOSE:To prevent the increase in the transmission loss of optical fibers at both ends of coated optical fiber ribbons housed within the slots of the optical cable by specifying the width and height of the coated optical fiber ribbons each having a U-shaped sectional shape to be respectively specific values. CONSTITUTION:The coated optical fiber ribbon 11 is constituted by arraying plural pieces of the optical fibers 2 to a U shape so as to have >=2mm width W thereof and >=0.3mm height H from the uppermost part to the lowermost part thereof and coating the surface with an integral coating layer 3. The optical cable 12 is constituted by superposing plural sheets of the coated optical fiber ribbons 11 and housing these fiber ribbons into the slits 14 which are provided on the outer periphery of a spacer 13 and have the U-shaped section. The coated optical fiber ribbons 11 are deformed to the inner side of the slots 14 and stresses are absorbed even if the ends of the coated optical fiber ribbons 11 are pressed to the side walls 14a, 14b of the slots 14. Then, the optical fiber elements 2 existing at the ends of the coated optical fiber ribbons 11 are prevented from directly receiving side pressures.

摘要： PURPOSE:To provide the space optical modulating element of a high contrast with a simple device. CONSTITUTION:This space optical modulating element 1 is constructed by holding transparent electrodes 3, an optical modulating layer 4, conductive electrodes 5, a photoconductive layer 6 and transparent electrodes 3' with substrates 2, 7 facing each other. An optical fiber plate of a small numerical aperture forming plural pieces of optical transmission paths is used as the substrate 2 on the optical modulating layer 4 side. As a result, the angle at which reading out light 11 is made incident on the optical modulating layer 4 is decreased and, therefore, the reading out of the high-contrast image is possible.

摘要： PURPOSE:To accomplish energy saving by forming a sheet-form light emitting body from a textile consisting of optical fiber warps and wefts, bundling one end of the optical fibers to form a light reception part, a fixing this textile to a dark place, etc., of a structure, and illuminating it with the solar beam. CONSTITUTION:A textile 1 is formed from warps of synthetic fiber mono- filaments 2 and wefts of plastic optical fibers 3 free of any covering layer, wherein one end of the optical fibers 3 is bundled to form a light reception part 4. It is made possible to replace the warps 2 with wefts 3, and also made practicable that optical fibers are used as both warps and wefts. The textile 1 is a fixed to any dark place in the perimeter of the space surrounding the structure concerned B, such as its side wall or ceiling, and the light reception part 4 is located outside of the building. Thus the textile 1 serves as a sheet- form light emitting body, and thereby the surrounding space is illuminated with solar beams, which permits promoting the energy saving.

摘要： PURPOSE: To remove off-axis contrast and color slippage at the time of off-axis observation and to remove a parallax on a touch screen by adopting specific flat panel multi-layer structure. CONSTITUTION: The multi-layer structure of a flat panel LCD screen 80 includes one layer 74. Since the layer 74 is a specially designed and manufactured glass material and has both the characteristics of an optical fiber and a polarizer, the layer 74 called as a polarized optical fiber layer. The layer 74 in the structure 80 is used instead of conventional analyzer layer, upper glass layer and optical fiber layer and the layer 74 acting as an optical fiber material transfers an LCD image from an LC layer to the upper surface of the layer 74. Since an image is observed at a fixed visual angle (visual line 38) of 90 deg., a fixed 90 deg. angle of view is shown on the surface of the optical fiber and the observation of 90 deg. can be attained by a user also at the time of observing the layer 74 at an off-axis angle.
