摘要： PURPOSE:To take out insulating oil from a cylindrical doughnut-shaped cable storage rotary basket which is in a state of vacuum and rotation so as to pre vent generation of defectives by providing a communicating hole between a slit provided around the outer or inner periphery of the cylindrical doughnut- shaped cable storage rotary basket and the basket, and mounting a discharge pump on the bottom portion of the end of a pipe. CONSTITUTION:A cable storage rotary basket 5 stored in an impregnation tank 40 is so constructed as to be rotatable. An outer tube 29 is provided around the overall outer periphery of the rotary basket 5 and a slit 31 is provided between the rotary basket 5 and the outer tube 9. The slit 31 has a communicat ing hole 32 provided through the bottom portion thereof so that insulating oil is allowed to freely flow in from the rotary basket 5. At the bottom portion of the inside of the slit 31 an insulating-oil discharge pump 30 is connected to a pumping pipe 27 and is hung from the lid portion 3 of the impregnation tank through a sealing portion 24. The insulating oil can thus be taken out without any problem from the rotary basket inside the impregnation tank which is in a state of vacuum and rotation, and the work of normally feeding a cable is made possible, preventing generation of defectives.

摘要： PURPOSE:To make the accurate coincidence of the real length of string material with the value of length mark possible, by a method wherein when the measuring scale pulse generated in a rotary encoder has been conductor to the counter circuit to which the correction value of measuring scale error is presetted to reach the setting pulse number after correction, the string material is marked by operating a length marker circuit. CONSTITUTION:The rotary encoder for detection of measuring scale pulse 4 and the rotary encoder for detection of cable speed 5 are directly coupled to be rotated on the axis of measuring scale pulley 2. Then, each time the rotary encoder 4 inputs 9 pulses to a measuring scale error correction value setting input circuit 7 assuming a slippage error of 1% in the measuring scale pulley, the counter of counter circuit 6 outputs one pulse. The pulse from the counter circuit 6 is operated with the signal from a print contents program input circuit 9 in the operation circuit 8 of print contents and time, being inputted to a length marker control circuit 11 via a print letter width speed synchronous circuit 10 and accurate length marking is printed.

摘要： PURPOSE:To provide an effective conveyor which does not deform or break supporting rods, a guide rail and the flange portions of bobbins, nor pose any problem regarding the height at which it ties in with a construction machine, nor cause impact. CONSTITUTION:Iron bobbins 2a, 2b roll from a pretreatment site 5 onto the surface of a feed transfer plate 3 mounted on the upper portion of a driven chain sprocket, collide with a front-stage-side supporting rod Ab supported and secured to a roller chain C waiting in a predetermined position slightly above the surface of the plate 3, and stop as they are mounted on the feed transfer plate 3. The position of the center Ga of gravity of each iron bobbin stopped is biased to the front-stage-side supporting rod side of the conveyor. As the conveyor is rotated, the front-stage-side supporting rod is advanced toward the next-treatment site 6, the iron bobbins roll, a back-stage-side supporting rod Ba moves upward, and the flange face portions of the iron bobbins are placed on the supporting rods Ab, Bb, whereby the supply and transfer of the iron bobbins to the conveyor is complete.

摘要： PURPOSE:To provide a paper insulated electric power cable insulating oil pressurization-impregnation method capable of preventing inert gas from diffusing in insulating oil. CONSTITUTION:Paper insulated cable cores 5 are rolled up in a basket 3 housed in a vacuum dryer tank 1, and insulating oil 6 is injected therein. An oil partitioning plate 7 formed of a non oil swelling and non gas permeable natured material is arranged so as to cover the surface of this insulating oil 6 under a floating condition, and insulating oil 8 is injected onto this additionally. Then, pressurization impregnation is carried out by forcibly charging inert gas in the vacuum dryer tank 1.

摘要： PURPOSE:To perform curing work easily in a short time by making cuts in a crosslinked polyethylene insulator, from the outer circumference to the conductor, at several points in the longitudinal direction. CONSTITUTION:A crosslinked polyethylene cable core 3 comprising a conductor 1 extrusion coated with a crosslinked polyethylene insulator 2 is wound around a drum and then the terminal thereof is rewound to be cured. A marginal length of l, which will be discarded finally, is ensured in the axial direction from the end face to the core body at the cable core terminal. Cuts are then made at several points in the longitudinal direction in the marginal part (l) of the crosslinked polyethylene insulator 2 at the cable core terminal by means of a chain saw or a band saw.

摘要： PURPOSE:To enhance effectiveness in works and the quality of traction cables by placing trucks with cable receptacle roller, which provides possibility of coupling and decoupling the cables automatically, on the rails for traveling of a movable sheave and thereby priventing the cable from slackening by simple construction. CONSTITUTION:Trucks 4 are placed on the rails designed for traveling of a movable sheave 2, and coupling and decoupling means 7, 8 are installed between the sheave 2 and trucks 4 and between trucks facing each other. When this movable 2 sheave 2 travels toward the stationary sheave 1, a traction fitting 10 is put in engagement with an L-shaped metal 11 to drive the truck 4 forward. When the sheave 2 travels in the direction apart from the sheave, 1, the metal 11 moves in engagement with the fitting 10, where a crank 12 comes in contact with a position setting piece 9 and is rotated to cause disengagement. Thus slackening of the cable is prevented by the truck 4 equipped with a cable receptacle roller 6.
