摘要： PURPOSE:To extend the life of a discharge electrode and to stabilize discharge by changing the polarities of a voltage impressed to the discharge electrodes for each discharge of one connection. CONSTITUTION:Spark discharge is caused between the electrodes 3 by the voltage of a high voltage part 6 and a switching part 8 flows a DC current from a low-voltage part 7 to the electrodes. The switching part 8 consists of a switch maneuver 10 associated with a discharge start switch 9 or the series circuit of a diode 11 and a high resistance 12 connected to the voltage part 6. The capacity and weight of a transformer for an electrode power source are reduced greatly, but discharge in the same direction of the electrodes is caused by the DC discharge current and only one electrode wears remarkably, so a switch 13 which changes the polarities of the voltage impressed to the discharge electrodes 3 for each discharge of one connection is added and operated associatively with the discharge start switch 9 to prevent only one electrode from wearing.

摘要： PURPOSE:To enable connection with high accuracy by using a plug of a simple construction by joining by melt sticking the ends of both optical fibers to be connected to a standard optical fiber having high dimensional and shape accuracy, and positioning the end face of the standard optical fiber on the end face of the connector plug. CONSTITUTION:The end faces of respective optical fibers 4, 4 are joined by melt sticking to optical fibers 9, 9 of a core 6 by using the length at which the light loss of the core 6 having a standard optical fiber 9 of high dimensional and shape accuracy is negligible in connection of the optical fiber cores 3, 3 of optical cables 8, 8. The core 6 is cut so as to allow the fibers 9, 9 to remain to a prescribed length from the melt stuck juncture 7 as shown by broken lines. The end faces of both fibers 9, 9 are aligned to the end faces of plugs 1, 1, and the plugs 1, 1 are connected in a sleeve 2. Even if the fibers 4 and the hole diameter of the plugs 1 are not finished to high accuracy, the easy connection with high accuracy and low loss is made possible by using the fiber 9, and on- site connection is feasible, thus the method is helpful in reducing the cost.

摘要： PURPOSE:To perform safe leading of good workability and high quality by electroheating the covering layer on a fiber strand and removing the same by decomposition at the time of leading of an optical fiber. CONSTITUTION:An electric heating wire 8 is wound in a coil shape, and a power source transformer 10 is connected to this wire 8. Its heating temp. is made controllable by a changing-over switch 11. The secondary covering layer 7 of an optical fiber 1 is beforehand removed to expose a primary covering layer 6, and the exposed part is inserted and retreated into the cylinder of the wire 8, whereby it is heated. By such heating, the thermosetting resin such as epoxy resin of the primary covering layer 6 is smoothly and quickly heated and decomposed. The sludge formed by this decomposition is wiped away by a cloth or the like impregnated with an alcohol or the like. With such constitution, the safe leading of good workability and high quality is accomplished.

摘要： PURPOSE:To obtain the device which permits low loss-bonding of optical fibers by connecting the two optical fibers having been removed of covering through simple mechanical operation within the V-groove. CONSTITUTION:A V-groove substrate 1 is fixed onto a V-groove connector fixing table 11 and a fiber retainer plate 4 and clamps 5 are lifted up by plates 12a, 12b. Thence, fibers are set in a fiber holding part 9. When a lever 13 is pulled in the arrow direction in this state, the fibers are entered into a fixing groove 3 by mechanism such as connecting part 14. When the lever 13 is pulled again, the two fibers are butted on the groove 3. Further the plate 12b is lowered to fix the fibers and this completes the connection. In this way, the two optical fibers may be connected at low losses by setting the optical fibers having been removed of the covering in the V-groove substrate and only through simple mechanical operation for the rest.

摘要： PURPOSE:To perform leading capable of maintaining high quality safely with good workability by dipping the covering layer on a fiber strand together with said strand in a heated high temperature oil or the like thereby decomposing and removing the same. CONSTITUTION:Oil 9 such as silicone oil or the like is filled in the upper cylinder of a cylindrical oil bath 8 composed of a metal, e.g., silver or the like and a cartridge heater 10 or the like as a heating means is contained in the lower part. The temperature of the oil 9 is controllable by the action of said heater 10. The entire part of the oil bath 8, except the opening in the upper part, is enclosed by a square heat insulator 11. The portion exposed with the primary covering layer 6 having removing the secondary covering layer 7 of the fiber 1 is dipped and heated in the oil 9 of the oil bath 8 constituted in this way. Thereby, the primary covering layer may be removed by thermal decomposition extremely smoothly and rapidly.

摘要： PURPOSE:To perform melt-sticking of aligned axial lines with simple and inexpensive constitution by providing a mirror which projects the joint part of optical fibers insertably between the optical fibers and electrodes. CONSTITUTION:Optical fibers A1, A2 are set to support tables 4, 5, and exposed parts B1, B2 are opposed in the position between electrodes 10, 11. When a mirror solenoid 25 is energized, a movable iron core 26 is lifted, and a mirror supporting table 20 is turned in an arrow (a) direction around a pin 21, by which a mirror 23 is inserted into between the joint part of the parts B1, B2 and an electrode 16 at a 45 deg. angle of inclination. The operator observes the top surface of the joint prt of the parts B1, B2, and the side face projected on the mirror 23, and aligns the axial lines. When the solenoid 25 is deenergized, the mirror 23 is reset by a spring 28. Discharge is caused between the electrodes 10 and 11, thereby melt- sticking the parts B1, B2. Thus, the melt-sticking of aligned axial lines is accomplished with the simple and inexpensive constitution.

摘要： PURPOSE:To carry out tension test in succession to melt connection by providing a tension test mechanism to one of a pair of holders so as to move the melt-connected part by a constant force in the direction where a tension acts upon said part after the melt-connection of optical fibers. CONSTITUTION:If electric power is conducted to rotary solenoids 30, 31 after optical fibers A1, A2 are set in the grooves 18, 18a of slip tables 12, 12a, turning iron cores 34, 34a, and this turning is transmitted from pinions 42, 42a to the gear parts 16, 16a of the tables 12, 12a, by which the tables 12, 12a are turned around pins 15, 15a, and the fibers A1, A2 are moved closer to each other. If the electric conduction to the solenoids 30, 31 is cut off after the melt-connection of the fibers A1, A2, the tables 12, 12a are turned in mutually aparting directions, but at this time, the tensile forces correspondig to the recovering repulsive forces of coil springs 43, 43a act upon the connected part of lead parts B1, B2, whereby a tension test is carried out.
