摘要： PROBLEM TO BE SOLVED: To provide an apparatus for producing a wire for an optical fiber capable of keeping the outside diameter of the wire for the optical fiber constant even under wide operating conditions ranging from a low to a high wire drawing speeds. SOLUTION: This apparatus for producing a wire 7 for an optical fiber comprises a resin die 6 for a bare wire 3 for the optical fiber, a cooling cylinder 5, installed in the former stage of the resin die 6 and capable of regulating the temperature of the bare wire 3, an outside diameter measuring instrument 8, arranged in the latter stage of the resin due 6 and capable of measuring the outside diameter of the wire 7 for the optical fiber and an outside diameter controller 9 capable of feeding back a control signal obtained by performing the computing based on the measured values of the outside diameter of the wire 7 to a flow control device 14 for a cooling gas 10 fed to the cooling cylinder 5. The temperature of the wire 3 for the optical fiber just before entering the resin die 6 is regulated on the basis of the actually measured outside diameter of the wire 7 for the optical fiber to thereby keep the outside diameter of the wire 7 for the optical fiber constant.

摘要： PROBLEM TO BE SOLVED: To provide the subject apparatus capable of threading a fiber in a state in which a dancer sieve of a dancer roller is kept in nearly intermediate position and threading the fiber at an increased traveling rate by providing a specific constitution in an apparatus for producing the optical fiber. SOLUTION: A capstan 29 for threading fiber is provided between a dancer roller 7 and a winder 8. Since optical fiber 12 after threading the fiber through a dancer sieve 22 of a dancer roller 7 is threaded through the capstan 29 for threading and taken up when threading of fiber is carried out at an initial stage in starting production or after causing trouble such as breakage, the take up speed can be controlled so as to be synchronous with take up speed of the take up capstan 5 and the dancer sieve 22 can be kept at nearly intermediate position (a) thereby. As a result, the number of revolutions of winder 8 is not speeded up in threading the fiber and winding and fixing around the bobbin is made easy and threading of fiber can be carried out at a higher threading speed than conventional speed.

CONSTITUTION:The flanges 4, 9 are projected at both end parts of the outer periphery of the pulley body 1 and a peripheral groove 17 is formed between both flanges 4, 9, and the electric power is supplied into the wire rod 18 hung over the peripheral groove 17 through the pulley body 1 to heat the wire rod 18. In this power supplying pulley, the flange 4 is made to be the fixed flange fixed to the body 1 and the flange 9 is made to be the movable flange which is loosely fitted on the outer peripheral surface of the body 1 so as to be movable in the axial direction. Further, a coil spring 13 as the flange energizing means for energizing the flange 9 to the flange 4 side so as to be able to press- hold the wire rod 18 hung over the peripheral groove 17 with flanges 4, 9, is arranged.

摘要： PURPOSE:To so constituting the title method that an actual pressurizing force is made into a preset value reliably and balance control of a slide does not exert bad influence on control of actual pressurizing force, by a method wherein along with control of the first control valve of each of levelling cylinders by a specific means the second control valve of each of the levelling cylinders is controlled under specific conditions. CONSTITUTION:A servovalve 12 is actuated by giving pressurizing force of a main cylinder 4, supporting reaction force of each of levelling cylinders 8, preset actual pressurizing force and pressure which has been calculated with the other value and is to command each of the cylinders 8 to a servoamplifier 17. In this instance, feed back of the pressure of the cylinder 8 detected by a pressure detector 14 is performed and the actual pressurizing force acting upon resin is controlled at a fixed level. When a difference between a top and bottom positions of a piston rod of each of the cylinders 8 detected by each of position detectors 15 exceeds a fixed value in a detection processing time, balance control of a slide 5 is performed by contracting a cylinder 8 by extracting a microscopic quantity of hydraulic oil from an oil chamber on the lower side of the cylinder 8 to such an extent as to not affecting control of the servovalve 12 by actuating a valve 13.

摘要： PURPOSE:To mold a molded body with uniform coating thickness by a method wherein a mold is opened once after the pressure molding of resin and, after the specified corrections are given to the mold, filler and the like, the resin is pressure-molded again. CONSTITUTION:After the molding of resin, the vertical inclination of a slide 5 is measured with measuring devices 10 and memorized in the memory of a computer or the like. Next, the slide 5 is raised so as to form a gap for filling coating material between a top force 7 and the molded resin. In this case, after the position control of the slide 5 is performed so as to make the clearance of the gap between the top force 7 and the molded resin uniform, coating material is filled into the gap. After that, the slide 5 is lowered through the parallel control of the slide 5. Finally, the pressure molding of the resin is performed again so as to obtain a uniform coating thickness.

摘要： PURPOSE: To prevent hardening or soldifying of fluid in the clearance at the side face of gear rotor by arranging an annular seal member coaxial with the gear rotor shaft to the sideboard of housing.
CONSTITUTION: An operating clearance 8 is formed between the gear rotors 4, 5 of gear pump and the sideboard 3 of housing. An annular seal member 13 coaxial with the rotor shaft is provided to the sideboard of housing at the position furthest from the rotor shafts 6, 7 on the side face of gear rotor to press the contacting face of seal member through a spring 18 against the side face of gear rotor. Since resin fluid will never flow into the clearance at the side face of gear rotor and hardened or solidified, proper operational clearance can be set freely.
