摘要： PURPOSE:To safely and surely execute branching and connecting in a hot-line state by longitudinally scoring the coating around fibers to the extent of not arriving at the fibers, then separating the fibers by each required number of fibers while tearing the coating between the fibers without using a blade. CONSTITUTION:The coating of the ribbon of coated fibers formed by arraying plural optical fibers in one row and integrally coating the fibers is first scored on the surface along the boundaries between the fibers to be branched of the ribbon of coated fibers 2 in order to branch the tape fibers in the longitudinally torn form in the hot-line state. The coating is longitudinally scored to about the extent at which the scores doe not arrive at the fibers. The fibers of the one group bordering at the formed scores and the fibers of the other group are respectively held. The held fibers of the one and the other groups are relatively moved in the direction intersecting with the plane of the ribbon of optical fiber and the holding points of the optical fibers of the respective groups are moved in the longitudinal direction of the ribbon of coated optical fibers, by which the fibers are branched.

摘要： PURPOSE:To rapidly set up one ferrule to a coaxial collision contact position with the other ferrule by its lateral movement to switch the connection of ferrules by forming two ferrule fixing parts on a holding frame and securing only a space allowing two ferrules are accurately and laterally arranged in parallel. CONSTITUTION:The holding frame 4 bends a long plate-like member and forms ferrule fixing parts 41, 42 formed like V-shape by contact faces 4A, 4B on mutually opposed positions. The ferrules F1, F2 are housed in the ferrule fixing part 41 so as to be coaxially and opposedly brought into contact with collision and both the ferrules F1, F2 are mutually pressed in the axial direction by a spring part 61. The ferrule fixing part 42 holds a cylindrical substitutive cylindrical body 5 having the same diameter as that of the ferrules F1, F2. The ferrules F1, F2 and the cylindrical body 5 are allowed to be slided only in the axial direction. Consequently, the connection of optical fiber lines can be rapidly switched by replacing the ferrule of a new optical fiber line by the substitutive cylindrical body 5 and moving one connected ferrule in the horizontal direction.

摘要： PROBLEM TO BE SOLVED: To provide a process for easily manufacturing an optical glass with small residual strain and a process for manufacturing an optical fiber excellent in UV resistance property and ultraviolet transmission efficiency. SOLUTION: The glass preform 3 is manufactured by forming a second glass part 2 around a first glass part 1 through plasma outside vapor deposition, wherein the first glass part 1 comprises fluoridated glass formed through VAD (vapor-phase axial deposition), and the second glass part 2 comprises fluoridated glass with a higher fluoridation concentration than that in the first glass part 1. The optical glass with a small residual strain is manufactured by processing this glass preform 3 and subsequently removing the second glass part 2. The optical fiber excellent in UV resistance properties and ultraviolet transmission efficiency is manufactured by drawing the glass preform 3 into a fiber without removing the second glass part 2.

摘要： PROBLEM TO BE SOLVED: To manufacture with good cost performance and to prevent a forgery, by incorporating a resistance value intrinsic for a pattern of each card in one or both of whether the pattern is formed in an intrinsic wiring shape and whether a component of a transparent conductive material is altered or not. SOLUTION: The card 1 is constituted of a base material 2 of a plate-like or film-like glass, plastic, paper or the like and a pattern 3 formed in an intrinsic wiring shape by using a transparent conductive material containing an ITO, ATO, ZnO or the like as a component, and a resistance value decided according to the wiring shape of the pattern 3 and the component of the conductive material to be used is used for identifying each card. Thus, the pattern 3 of the card 1 has the intrinsic resistance value according to its wiring shape and the component, and the resistance value between terminals is externally measured by using input terminals I0 to I8 and output terminals O0 to O8. Thus, whether the card is true or not can be collated by utilizing the measurable resistance value and the card can be identified.

摘要： PURPOSE: To obtain such an optical fiber probe that can be easily inserted into a small hole without scratching the area around the objective point, and even when cracks or chipping are caused during cutting the probe, these cracks and chipping is removed and uniform smooth surface can be formed, and that chipping on the output end face is not caused during being used and the probe is hardly contaminated and can be used for a long time, by rounding the corner of the output end face by fusing. CONSTITUTION: An optical fiber 4 consists of a coating 3 and a glass part comprising a light-transmitting core 1 and a reflecting clad 2 and is processed by exposing the top glass part so that the end face of the exposed part 5 is used as the output face 6 for light. The corner 7 of the output end face 6 is fused and rounded. First, the coating 3 is partly removed from the optical fiber 4 to expose the end area 5. The area within 10mm-20mm apart from the coating end of the exposed part 5 is cut with a cutting toil to form the output end face 6. After the exposed part 5 and the output end face 6 are cleaned, the fiber is mounted on a discharging device. With this discharging device, the output end face 6 and the surrounding area are uniformly heated by discharging while the fiber is rotated in several steps.
