    摘要： In an optical fiber laying structure for an electric power cable line trouble occurrence location detecting system for detecting a trouble occurrence location by laying an optical fiber along an electric power cable line, the portion of the optical fiber laid along the cable of one of the two adjacent sections is superposed on the portion of the optical fiber laid along the cable of the other sections in an area in the vicinity of the boundary of the electric power cable line. Thus, if a temperature rise occurs due to a trouble such as a ground-fault in the boundary area, the temperature peak position, i.e., the trouble occurrence location can be detected by the two different optical fibers. Therefore, the trouble occurrence location in the boundary area can be accurately detected.

    摘要： A temperature abnormality detecting structure for a fluid pipe detects a temperature abnormality location by laying an optical fiber serving as a temperature detecting portion of a Ramam scattering optical fiber distribution type temperature sensor along a fluid pipe. The fluid pipe is divided into a plurality of sections in the longitudinal direction, independent optical fibers are laid along the fluid pipe in the respective sections. A portion of the optical fiber laid along one of the adjacent sections is superposed to be laid on a portion of the optical fiber laid along the other of the adjacent sections in the vicinity of each of the respective boundaries of the sections. Since the portion of the optical fiber laid along the pipe of one of the two adjacent sections is superposed on the portion of another optical fiber laid along the pipe of the other of the adjacent sections, if an abnormal temperature change occurs due to a trouble such as leakage or outflow of the fluid from the pipe in the boundary area, the temperature change peak position, i.e., the abnormality occurrence locations is detected by the two different optical fibers. Thus, the detecting accuracy is remarkably enhanced as compared with a case wherein the abnormality is detected by only one optical fiber.

    摘要翻译： 用于流体管的温度异常检测结构通过沿着流体管布置用作拉姆马斯散射光纤分布型温度传感器的温度检测部分的光纤来检测温度异常位置。 流体管在长度方向上被分成多个部分，独立的光纤沿着各个部分中的流体管铺设。 沿着相邻部分之一布置的光纤的一部分被重叠放置在沿着各部分的各个边界附近的相邻部分中的另一个布置的光纤的一部分上。 由于沿着两个相邻部分中的一个的管道布置的光纤的部分叠置在沿着另一个相邻部分的管道放置的另一光纤的部分上，如果由于诸如此类的故障而发生异常温度变化 由于流体从边界区域中的管道泄漏或流出，所以通过两根不同的光纤检测温度变化峰值位置，即异常发生位置。 因此，与仅通过一根光纤检测到异常的情况相比，检测精度显着提高。

    摘要： A projection optical system for photolithography includes a refraction sub-system and a cata-dioptric sub-system optically connected to each other. The refraction sub-system extends at an object side. The cata-dioptric sub-system extends at an image side. The refraction sub-system is generally composed of refracting members. The cata-dioptric sub-system is generally composed of a phase compensating member, a concave mirror, and a convex mirror. The phase compensating member adjoins the refraction sub-system. At least the concave mirror has a central opening through which light passes. The light forms an image at a rear of the concave mirror.

    摘要： A method is disclosed in which an insulating film of an oxide of metal, of which a stranded conductor (30) is made, is formed on the surface of all strands in a stranded conductor, while the stranded conductor is held in the stranded form. In a step of oxidation-treating the strands of an electric cable the pressure of an oxidation treatment solution at the outer portion of the stranded conductor immersed therein is made higher than the pressure in the inner portion of the stranded conductor (30), causing the oxidation treatment solution (48) to be adequately penetrated from the outer portion into the inner portion of the stranded conductor to permit a desired oxide film to be formed on the surface of all the strands in the stranded conductor. In order to more facilitate the penetration of the oxidation treatment solution (48) wholly into the interior of the stranded conductor (30) and the more facilitate an oxidation reaction, vibrations are, in addition to this method, imparted to the stranded conductor (30) in the oxidation treatment step (40) to cause the untwisting of the stranded conductor (30) to be effected to some extent, while the stranded conductor being heated is entered into this step.
