Abstract: Disclosed is an adjuvant for use in simultaneous polishing of a cationically charged material and an anionically charged material, which forms an adsorption layer on the cationically charged material in order to increase polishing selectivity of the anionically charged material, wherein the adjuvant comprises a polyelectrolyte salt containing: (a) a mixture of a linear polyelectrolyte having a weight average molecular weight of 2,000˜50,000 with a graft type polyelectrolyte that has a weight average molecular weight of 1,000˜20,000 and comprises a backbone and a side chain; and (b) a basic material. CMP (chemical mechanical polishing) slurry comprising the above adjuvant and abrasive particles is also disclosed.

Abstract: Disclosed herein is an automobile lead-acid battery, which comprises a case internally divided into a plurality of separate cells by a plurality of partitions, a plurality of positive plates and a plurality of negative plates alternately interleaved with one another within each of the plurality of cells. A separator is disposed between the positive and negative plates to separate them. An electrolyte is filled in the remaining space of each cell. The positive plate includes an upper frame formed at one side with a lug protruding upwardly, a lower frame positioned in parallel with the upper frame, side frames coupled to both ends of the upper and lower frames to thereby form a square framework with four rounded corners to prevent damage to the separator. A plurality of inner grids is disposed within the square framework and taking a radial shape.

Abstract: A clip to align a fiber optic cable with a light source within a fiber module. The clip may have a pair of sidewalls that are separated by a channel. The fiber optic cable can be located within the channel of the clip and attached to the sidewalls. The sidewall are adjoined by a pair of joining segments. The joining segments are separated by a space which allows a ferrule of the fiber optic cable to be welded to a center location of the clip.

Abstract: A process for laser welding a ferrule of a fiber optic cable to a clip of a fiber module. The process can detect and correct a movement of the fiber optic cable so that the fiber is aligned with a light source such as a laser diode. The detection method includes the steps of mechanically moving the ferrule with an automated device after a weld is completed and then detecting a change in optical power of a light beam that is transmitted through the fiber optic cable. The detection can determine a direction that the ferrule shifted during the weld process. The shift of the ferrule can be corrected by subsequent laser welds of the ferrule and clip. The power and time duration of the laser welds can be determined from an empirically derived look-up table. The entire process of detection and correction can be automated.

Abstract: An automated computer controlled process optical fiber splicing system 11 which yields consistent, high strength, low loss, high quality splices. The system of the invention includes a positioning system 17, 21, 29, and 31 for moving at least two optical fiber ends 15 and 19 into relative alignment at a junction 23. A high intensity beam of energy 37 is directed at the junction 23 of the fibers to achieve the high temperatures required for fusing the ends thereof. The focus of the beam 37 is adjusted to control the temperature profile of the energy applied to the junction 23.

Abstract: Two optical fibers are spliced together to form a single spliced optical fiber. The spliced region is uncontaminated by impurities, and has substantially no loss of optical transmission or mechanical strength as compared to the other regions of the fibers. Splicing is accomplished by removal of the buffer coating, if any, cleaving of the fibers to be spliced to form facing splicing surfaces, careful precleaning of the cleaved fibers in the region adjacent the splicing surfaces, aligning the fibers using optical transmission as the alignment criterion, fusing the fibers together by preheating the region to be spliced, fusing the region, postannealing the spliced region, carefully postcleaning the spliced region, and recoating the spliced region with a UV curable polymer buffer material, if desired. The heating of the fibers to accomplish the fusion is desirably accomplished by a laser such as a carbon dioxide laser.
