摘要： Disclosed is a segmented core optical waveguide fiber having low total dispersion slope and negative total dispersion over an extended wavelength window. A wavelength window of particular interest is that in the range of about 1500 nm to 1600 nm. The waveguide fibers in accordance with the invention also have cabled cut off wavelength below about 1480 nm and attenuation at 1550 nm of less than 0.22 dB/km. Mode field diameter is maintained essentially at the nominal value for dispersion shifted waveguide fiber, i.e., 7.7 &mgr;m to 8.7 &mgr;m. Embodiments having a center segment and a first and a second annular segment are discussed in detail.

摘要： An upper/insole assembly for use in constructing an article of footwear includes an upper and an insole. The upper has an inner surface, an outer surface, a lateral peripheral flange, and a medial peripheral flange. The insole has a top surface, a bottom surface, a lateral peripheral edge, a medial peripheral edge, an arch portion, a phalangeal portion, and a heel portion. At least a portion of the lateral and medial peripheral flanges of the upper are stitched to the insole in the phalangeal and heel portions but they are not stitched to the insole through the arch portion. Additionally, the lateral peripheral flange of the upper is wrapped around the lateral peripheral edge of the insole in the arch portion and the medial peripheral flange of the upper is wrapped around the medial peripheral edge of the insole in the arch portion. Moreover, the lateral and medial peripheral flanges are secured to the bottom surface of the arch portion of the insole. An article of footwear includes the upper/insole assembly and a bottom component that includes an outsole component, a midsole component, and preferably at least one shank that provides support to the arch portion of the upper/insole assembly and article of footwear. At least a portion of the midsole component is fixed to the upper/insole assembly. A method for manufacturing an upper/insole assembly includes stretching an upper over a last such that a lateral peripheral flange and a medial peripheral flange of the upper extend past the edges of a lateral peripheral edge and a medial peripheral edge of an insole; adhesively securing an inner surface of the lateral peripheral flange to a bottom surface of an arch portion of the insole; adhesively securing an inner surface of the medial peripheral flange to the bottom surface of the arch portion of the insole; stitching the upper to a heel portion of the insole; and stitching the upper to a phalangeal portion of the insole.

摘要： Disclosed is a single mode optical waveguide fiber having a core refractive index profile in which the profile parameters are selected to provide an attenuation minimum. A set of profiles having the same general shape and dimensions is shown to have a group of profiles contained in a sub-set which exhibit a minimum of attenuation as compared to the remaining members of the set. The members of the sub-set have been found to have the lowest effective group index, n.sub.geff, and the lowest change in .beta..sup.2 under waveguide fiber bending.

摘要： A single mode optical waveguide fiber having low, non-zero dispersion over a pre-selected wavelength range is disclosed. The refractive index profile of the core is characterized in that the core includes a plurality of distinct regions, each having an index profile, and a radius or width. By adjusting the index profile sizes and shapes of the plurality of core regions, a waveguide fiber may be made having a set of properties tailored for a high performance telecommunication system. In particular, dispersion slope can be maintained less than 0.05 ps/nm.sup.2 -km and absolute magnitude of total dispersion maintained in the range of 0.5 to 3.5 ps/nm-km over a pre-selected wavelength range. The zero dispersion wavelength is outside the pre-selected wavelength range and the cut off wavelength and mode field diameter are controlled to target values.

摘要： Disclosed is a real floor for a lauter tun comprising a plurality of elongated linear troughs, each trough extending unobstructed across the bottom of the vessel and each forming a relatively shallow upward opening V-shape. The elements making up the floor are shaped to provide the lauter tun floor with a circular profile.
