摘要： In the manufacture of a fiber reinforced plastic armored cable, long reinforcing fibers are impregnated with an uncured thermosetting resin and formed into a predetermined shape to obtain a plurality of rod-like members with the thermosetting resin held uncured. Then the uncured rod-like members are passed through a die of a melt extruder, by which the rod-like members are each coated with a thermoplastic resin layer. The coated layers of the rod-like members are immediately cooled to simultaneously form a plurality of fiber reinforced plastic armoring strands with the thermosetting resin held uncured. The armoring strands thus obtained are wound around a cable which is fed while being rotated. The cable having wound thereon the strands is passed through a die portion of a melt extruder, by which the cable is sheathed with a thermoplastic resin layer which is immediately cooled and solidified. The sheathed cable is guided into a curing tank using a liquid as a heating medium to cure the thermosetting resin in the armoring strands. Thereafter, the sheathed cable is wound onto a drum via a rotary take-up device.

摘要： Actuation of a prefatiguing lamp is selectively controlled in accordance with the measured time interval between successive copying operations. In substantially continuous copying where the measured interval is less than a first predetermined time period, no prefatiguing illumination is provided. Where the measured interval exceeds a second, longer predetermined time period, full illumination is provided. When the measured interval is between the first and second predetermined periods, partial illumination is provided by appropriate reduction in the operating voltage impressed upon the prefatiguing lamp.

摘要： In an optical fiber carrying spacer which has helical grooves for carrying optical fibers with each groove changing the direction of its helix for each turn about the spacer, each helical groove includes extra-length portions and compensating portions both formed at a smaller angle to a longitudinal axis of the spacer than main groove portions. The extra-length portions are each provided at a position where the direction of the helix changes. The compensating portions are each provided between adjacent extra-length portions at an angular distance ranging from 1/4 to 3/4 of the circumference of the spacer. The spacer effectively prevents stresses from being applied to the optical fibers along the longitudinal direction when the spacer is bent or curved.
