摘要： A method of connecting an optical waveguide to an optical fiber, in which an optical waveguide and a marker are formed at the same time on an optical waveguide substrate when patterning an optical waveguide by photolithography method, the waveguide is buried into a clad layer formed in other area than said marker, grooves for insertion pins are formed with the marker as a positional reference, and an optical waveguide module is connected to an optical fiber connector by the use of said grooves for insertion pins. In this way, an expensive positioning/setting device is no more needed and an optical waveguide can be connected to an optical fiber in alignment with each other and in an exceedingly simple manner and a short period of time.

摘要： According to discriminating method of the present invention, terminal-treated end portions of a covered multiple-fiber cable (1) and a ferrule (11) are set on a pair of support bedplates (31 and 36), respectively, the end portions of the respective optical fibers 21-24 and respective optical fiber holding portions (concave grooves 171-174 and insert holes 181-184) of the ferrule (11) are opposed to each other, thereafter, when the respective end portions of the optical fibers 21-24 and the respective optical fiber holding portions are positioned in alignment with each other so as to insert the respective end portions of the respective optical fibers into the respective optical fiber holding portions, prior to insertion, during insertion and after insertion, information on the respective end portions of the optical fiber and the respective optical fiber holding portions are picked up by an image processing device (51) or an optical sensor (62) and the said information is processed by an operational means (50 or 63), whereby discrimination is made as to whether the relative positional relationship between the end portions of the optical fibers and the optical fiber holding portions and the state of combination are proper or not.

摘要： A semiconductive resin composition essentially comprising 100 parts by weight of a base resin which comprises an olefinic polymer having a crystalline melting point of lower than 86 °C or a mixture of said olefinic polymer with another olefinic polymer having a crystalline melting point of 100 °C or above, does not have any crystalline melting point in the temperature range from 86 °C to lower than 100 °C and has a crystallinity of 20 to 35 %, and 40 to 80 parts by weight of conductive carbon black comprising acetylene black and/or furnace black. A rubber/plastic insulated power cable wherein the internal and/or external semiconductive layer is formed from the above composition or the cross-linked derivative thereof. Since the crystalline part of this composition does not melt at the service temperature of the cable, the composition serves to control the lowering and destabilization of conductivity, to inhibit the rise of a tan δ value, and to prevent the performance of the power cable from being deteriorated.

摘要： A joined metallic work produced, in general, by metallurgically joining a shaped member of nickel-titanium alloy and another shaped member of nickel-base alloy while forming a forging texture between the two members. The production process comprises momentarily heating the joining sites of the two members in an inert atmosphere and pressing these sites in a thermally softened state against each other at a high pressure to form a forging texture therebetween.

摘要： A quartz glass doped with rare earth element, aluminium and further fluorine, and endowed with various characteristics such as practicable luminescent properties, high amplification gain, achievement of wider band, size reduction of elements, fusibility and connectivity of quartz glasses with each other, and so forth. This glass is not accompanied with crystallization inherent in this type of doped quartz glass in the course of its producton, so that it is transparent of course and contains no residual bubbles. Since the production process comprises a combination of a technique for forming a porous glass with a method of solution impregnation, it is possible to produce readily a quartz glass doped with both rare earth element and aluminum, having high purity and excellent transparency, and being useful as an active optical element.

摘要： A repair material and a repairing method, in which partial repair for faulty portions of a pipeline such as a sewerage pipe is surely effected in fewer working processes and in a short time. A repair material (1) is used which is composed of at least two layered cylinders with an elastic inner layer (2) held in an outer layer (3) in contracted condition. The repair material is introduced into a pipeline to be taken to a location where the pipeline should be repaired, and the outer layer is removed to cause spontaneous diametrical expansion of the inner layer for close adherence to an inner surface of the pipeline. In the case where the pipeline is small in diameter, the outer layer (3) is removed outside the pipeline and only the elastic inner layer (2) is introduced into the pipeline to be conveyed to a location where the pipeline should be repaired. Before the outer layer (3) is removed outside the pipeline the repair material is cooled to temporarily delay a diametrically enlarging speed of the inner layer. Conveyed to a location where the pipeline should be repaired, the inner layer is heated.

摘要： An optical connector which correctly sets a protruding length of an optical fiber (5) protruding from a connection end face (16) of a ferrule (1), a method of setting the protruding length of the optical fiber of this optical connector and a jig therefor are described. A recessed surface (33) is formed in a ferrule receiving surface (32). The depth of the recess surface (33) is set to be equal to the protruding length of the optical fiber (5) protruding from the connection end face (16) of the ferrule (1). The ferrule (1) is clamped by ferrule clamping members (35a and 35b) and is pressed to the ferrule receiving surface (32) by the urging force of a compression spring (36). An optical fiber core wire (3) is passed through the ferrule (1), is allowed to protrude from the connection end face (16) of the ferrule (1) and is butted against the recess surface (33). The optical fiber core wire (3) is clamped by a core wire clamping member (41), which is urged toward the ferrule receiving face (32) by the urging force of a compression spring (42) so that the distal end of the optical fiber (5) is brought into pressure contact with the recess surface (33). An adhesive is charged under this state into an adhesive charging hole (43) of the ferrule (1) so as to bond and fix the optical fiber (5) to the ferrule (1), and an optical connector whose optical fiber (5) is allowed to protrude by a predetermined length from the connection end face (16) can be obtained.
