摘要： A barrel plating method wherein each box containing pieces to be plated is provided with a kanban corresponding to the pieces contained in the box. The kanban of each box is read by an apparatus before the pieces are transferred from the box to a plating barrel, so that a plating coefficient corresponding to the information read from the kanban is retrieved from a host computer in which plating coefficients for various kinds of pieces are stored. The plating coefficient retrieved corresponding to the kanban of each box is proportional to a value of plating current to be supplied to a unit weight of pieces contained in the box. A value of plating current for each barrel is automatically calculated by multiplying the plating coefficient by the measured weight of the pieces put in the barrel. Barrel plating is performed by supplying each barrel with the value of the calculated plating current from power sources that correspond in number to barrels that are subjected to a plating process at a given time.

摘要： An optical fiber cable includes a flexible pipe of a plastics material, and a group of optical fibers loosely mounted within an axial bore of the pipe and held in contact with an inner surface of a peripheral wall of the pipe. At least one elongated flexible reinforcing member is embedded in the peripheral wall of the pipe and extends along a longitudinal axis of the cable, the reinforcing member being disposed in the vicinity of the group of optical fibers and made of a material having a higher Young's modulus than that of the plastics material of which the pipe is made. The optical fiber cable has a neutral axis extending through the bore of the pipe and defining a line of zero stress when the cable is bent longitudinally in a direction to dispose the reinforcing member radially inwardly of the group of optical fibers. The group of optical fibers are disposed on the neutral axis, so that the optical fibers are not subjected to axial contraction or elongation when the cable is bent in the direction.
