摘要： An optical cable has a plurality of one-groove spacers 3 which are twisted in one direction around a central member 1. Anti-tensile elements 2 are arranged in the central portion of the central member 1. Each one-groove spacer having a single groove which is linear lengthwise and substantially square in cross section and holding a stack of a plurality of optical fiber ribbons 4. The inner width and the height of the side walls of the groove of the one-groove spacer are set greater than the diagonal length of the stack. Therefore, the transmission loss becomes reducible because the contact portions of the optical fiber ribbons with respect to the side walls of the grooves vary in the longitudinal direction, thus preventing a specific number of optical fibers from being continuously subjected to edgewise pressure.

摘要： In an optical cable made by forming a sheath on enclosing one or more optical fiber cores and a tension member, high reliability is obtained through the avoidance of adverse effects on the optical fiber core of a curving tendency of the tension member prevailing over the resistance of the sheath to curving (for example, due to the installed optical cable being heated by electrical equipment in proximity) and the optical cable consequently curving. Taking the plane containing the curve formed by the tension member due to its curving tendency as a base plane, the optical fiber core is disposed in the proximity of the position of the image formed when the tension member is projected in a direction perpendicular with respect to the base plane onto a flat plane separate from and parallel with the base plane. If the optical fiber core is an optical fiber ribbon comprising a plurality of optical fibers lined up in a flat plane and coated en bloc, then as an additional condition, an alignment line obtained by joining the centers of the optical fibers at both sides of the optical fiber ribbon is disposed perpendicular to the base plane.

摘要： An optical cable has a plurality of optical fibers. The optical fibers are contained in fiber containing cavities of chamber elements. Each chamber element has a bottom part and a pair of side wall parts, which defines a fiber containing cavity. The individual chamber elements containing the optical fibers are assembled around a thickening layer in an S-Z strand. Each side wall part is formed such that its thickness gradually decreases from its base end portion toward free end portion. Also, the thickness of the bottom part is greater than the thickness of each side wall part.

摘要： A disposable wearing article adapted to prevent indicators from being transferred to a liquid-absorbent structure and to make the indicators develop the color reaction quickly in response to a discharge of body exudates. A disposable diaper has a topsheet, a backsheet and a liquid-absorbent structure interposed between these top- and backsheets. A surface of a first backsheet facing the liquid-absorbent structure is formed with indicators. The indicators contain a hot-melt polymer, an indicator agent adapted to develop a color reaction and a plasticizing oil. The liquid-absorbent structure has a liquid-absorbent core, a liquid-diffusive wrapping sheet adapted to wrap the core. A hydrophilic bottom sheet is interposed between a bottom surface of the core and a bottom surface region of the wrapping sheet. A dimension in the transverse direction of the bottom sheet is larger than a dimension of a region in which the indicators are formed and smaller than a dimension in the transverse direction of the core.
