    摘要： Methods for curing a coating material, including a primary coating material, a secondary coating material, and a taping material, on an optical fiber. An optical fiber coating material having (A) 100 parts by weight of a polyether polyurethane bearing at least two ethylenically unsaturated groups with a Mn of 800-10,000, and (B) 1-40 parts by weight of a nitrogenous reactive diluent is cured by irradiating thereto electron beams, produced by driving electrons under an accelerating voltage of 50-190 kV, in a dose of 10-100 kGy. The method succeeds in effectively curing the optical fiber coating material into a cured coating having stable properties.

    摘要： An optical fiber is prepared by applying a liquid electron beam-curable resin composition to a bare optical fiber or a coated optical fiber having a primary or secondary coating on a bare optical fiber, irradiating electron beams to the resin composition on the optical fiber for curing while the optical fiber passes a zone under substantially atmospheric pressure, and providing a magnetic field and optionally an electric field in the zone for thereby improving the efficiency of electron irradiation. The method can comply with the increased drawing speed of the bare optical fiber and does not detract from the transmission properties of the optical fiber.

    摘要： An electron beam system for treating filamentary workpieces includes an electron beam irradiation chamber having openings through which passes a filamentary workpiece, an electron beam generator including means for generating, accelerating and focusing electrons, and a communicating section which connects the electron beam generator with the electron beam irradiation chamber. The system also has a differential evacuating means for holding the pressure within the electron beam generator below that within the electron beam irradiation chamber. Electrons are generated, accelerated, and focused by the electron beam generator into a beam which passes from the generator through the communicating section to the electron beam irradiation chamber where the beam is directed at a filamentary workpiece. The system is able to uniformly, efficiently, and continuously apply electron beam irradiation to a traveling filamentary workpiece. When used in the fabrication of optical fiber, this system can accommodate higher fiber drawing speeds without compromising the transmission characteristics of the resulting optical fiber.

    摘要： A conductive powder is provided in which particles having silicon crystallites dispersed in a silicon compound are coated on their surface with carbon. The conductive powder develops a diffraction peak assigned to Si(111) around 2θ=28.4° on x-ray diffractometry (Cu—Kα) using copper as the counter cathode, the peak having a half width of at least 1.0°, and has a specific resistance of up to 50 mΩ. The powder is used as a negative electrode material to construct a non-aqueous electrolyte secondary battery, which has a high charge/discharge capacity and improved cycle performance.
