摘要： PURPOSE:To disperse a tractive tensile force and to lay an optical fiber effectively by towing the tip of the optical cable by the 1st tow rope towing machine almost to the limit in the range of permissible tensile force of the optical cable, fixing the 2nd tow rope to the intermediate part of the cable, and towing the cable by both towing machines associatively and dispersedly. CONSTITUTION:The two rope towing machine 8 for towing the tip is driven to two the optical cable 5 and a measuring instrument 9 detects its tractive force increasing almost to the limit point within the range of the permissible tensile force of the cable and stops the towing machine 8. Then, the rear end of the 2nd towing machine 12 is detached from a drum 11 and fixed to the optical cable 5. The tip of the 2nd tow rope 10 is led to the 2nd towing machine 12 previously, so the tow rope towing machine 8 and the tow rope towing machine are driven at the same time to lay the optical cable with a dispersed tensile force. Consequently, no unreasonable force is applied to the optical cable and aerial layering is performed effectively.

摘要： PURPOSE:To increase the mechanical efficiency of a delivering apparatus, by improving the shapes of intermediate receiving rollers and inner circumferences of timing belts so that there is no fluctuation in pressing force to a long article such as cable. CONSTITUTION:A moderately high peessing section 7a is formed approximately at the center and around each of the intermediate receiving rollers 7, and a groove 8 having a shape complementary with that of the pressing section 7a to mate with the section 7a is formed along the longitudinal center of each timing belt 3. Therefore, the long article 6 clamped between the timing belts 3 is given a concentrated pressure continuously by the outer circumferences of the pressing sections 7a, and since the pressing sections 7a and the groove 8 are vertically aligned, the force gripping the long article 6 can be retained approximately at constant, so that slipping between the long article 6 and rotating bodies 4, 5 is eliminated and the mechanical efficiency of the delivering apparatus can be enhanced.

摘要： PURPOSE:To detect the traction state of a cable directly and to feed it out at an invariably optimum speed by detecting a transient state of transition from the 1st control state to the 2nd control state or vice versa and controlling a motor almost in the transient state. CONSTITUTION:A power unit 20 is provided with a current measuring circuit 23 and a voltage measuring circuit 24 and the output of a current control circuit 25 is checked. The current control circuit 25 is controlled by a controller 26, which inputs the output of the current measuring circuit 23 and the output of the voltage measuring circuit 24 and inputs those data to a sample and hold circuit 28 alternately from an analog switch 27 at a specific period. The data is converted by an A/D converting circuit 29 into a digital signal, which is supplied to a CPU 30 to perform discrimination processing. A current setter 32 sends a signal corresponding to a command signal from the CPU 30 to a comparator 33, which compares it with a measured current value to command the current control circuit 25 to increase or decrease a current. Consequently, neither a droop which is larger than required nor excessive tensile force is applied to the cable, which is laid at an optimum speed.

摘要： PURPOSE:To detect accurately cable sag by installing detecting arm and receiving seat surrounding the cable. means to support the receiving set horizontally and mechanism to convert electrically displacement of operating pin and pin. CONSTITUTION:A cable 16 is fed out by allowing it to pass through a detecting arm 1, 1. And, when the cable 16 sags to push LH or RH side of the arm 1 to give a thrust, the arm 1 inclines with a bearing 4 as the axis. Further, when the cable hits top or bottom, the cable 16 slips in LH or RG direction to tilt the arm 1. By the tilting of the arm 1, 0 receiving seat 5 pushes downward the head 12 of an operating pin 9 to move a rack gear 13. By displacement of the gear 13, a pinion gear 14 is rotatated and a shaft 15 fixed to the gear 14 is rotated. Namely, the rotating angle of the shaft 15 controls voltage or current, etc., and a controlling signal is fed back to a cable feeding apparatus 17 through a measuring instrument 28 and thus, the cable feeding sped is controlled.

摘要： PURPOSE:To reduce heat generation of a transistor and to make a device small in size, by inserting a resistor for heat generation sharing in parallel with a current adjusting transistor. CONSTITUTION:An AC electric power supply input from a power generator, etc. is received from a terminal 7, is rectified by a rectifying circuit 1, >=1 current adjusting transistors 2 and a current detection resistance 3 are connected in series, a DC output is obtained from a terminal 4, control voltage corresponding to an output current detected by said currnt detection resistance 3 is generated by a current controlling circuit 5, internal resistance of each current adjusting trnsistor 2 is increased or decreased, and a DC output of a constant current is obtained. In this case, the heat generation is shared by inserting a resistor 6 for heat generation sharing in parallel wth each current adjusting transistor 2. Accordingly, a transistor 2 having a small capacity can be used, and also the heat dissipation method for a resistor is much simpler than that of a transistor, therefore, a total cost of the electric power supply device is greatly reduced.
