Title: Machine for winding optical cable on overhead earth- wire
Inventor: MARUHASHI KATSUHIRO
IPC: H02G1/02
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To perform the winding operation of an optical cable onto an overhead earth-wire so as to wind the optical cable with properly fixed tension without being influenced by the weather and without depending on a winding speed. SOLUTION: The machine 21 for winding the optical cable is pulled and advanced by a rope 22, then the rotation of a running pulley 26 which rides on the overhead earth-wire 4 is transmitted to a rotary frame 24 through a rotary transmitting mechanism 27 and the rotary frame 24 is rotated around the periphery of the overhead earth-wire 4. A bobbin 25 attached to the rotary frame 24 is rotated around the overhead earth-wire 4 while feeding out the optical cable 9, which is wound on the overhead earth-wire 4. The rotation of the bobbin 25 is transmitted to a hysteresis brake 67, which brakes the bobbin 25 and the winding tension is applied to the optical cable 9. As the brake torque is not varied by moist and wetness, the hysteresis brake 67 can wind the optical cable 9 with the properly fixed tension even at rainy weather.  Further, as the brake torque is excellent in reproducibility and the winding tension can be set by using a scale, the mistake on the setting of tension does not occur. In addition, even when the winding speed is varied, the winding tension is not varied.

Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To apply an optimum gamma correction to gamma characteristics of a photoelectric conversion section by selecting a gamma correction table corresponding to a model of its own reader among model dependent gamma correction table group as a gamma correction table corresponding to each device. SOLUTION: A gamma correction table group is used by a plurality of devices in common and it is not required to change the table group for each device. In the meantime, table selection information is a head address of an optimum gamma correction table to the correction of the gamma characteristic as a result of confirming the gamma characteristic of a photoelectric conversion section 2 mounted on the image reader 1. Since the table selection information differs for each device, the information is stored not in a ROM 8 but in a backed-up RAM 9.  While the device configuration relating to gamma correction is made in common independently of the gamma characteristic of the mounted photoelectric conversion section 2, the optimum gamma correction to the gamma characteristic of the photoelectric conversion section 2 of the model of its own reader is realized to obtain an image with high image quality.
