Title: Head for forming end of rolled stock
Inventor: KOBAYASHI KAZUO
IPC: B21J1/04
Filed: 1989-06-12
Abstract: PURPOSE:To lessen the generation of a fish tail and to prolong the life of a tool by forming the end of a stock by means of forming heads, the section of which changes gradually from a semicircular shape to a rectangular shape and constitutes a groove coinciding with the section of the stock at the end face. CONSTITUTION:The groove of the press head 1d has the rectangular shape coinciding with the section of the rolled stock at the end face A. The groove has the slightly rounded rectangular shape in the part of the face B and the semicircular shape in the part of the face C and is recessed to the semicircular shape between the part of the face C and D. The shape between the face D and the end face E is the same shape as that of the face B and the end face A. The press head 1u to be paired therewith has the same shape as the shape of 1d. The generation of the fish tail after rolling is extremely lessened if the end face of the rolled stock 2 is rolled to a circular shape by using the press heads 1d, 1u. Since the shapes of the press heads 1d, 1u are simple, the life as the tool is prolonged and the working efficiency is improved.

Abstract: PURPOSE:To provide the distribution coupling type period branching filter of low losses which do not produce any characteristic degradation owing to aging by so working two eccentric core optical fibers that when their worked faces are mated they assume a nearly circular section then fusion bonding the same. CONSTITUTION:The side faces of a large thickness of the clad parts 41, 42 of optical fibers in which the centers of cores 31, 32 deviate from the centers of the optical fibers are worked flat over the specified length, whereby their sectional shapes are made nearly semicircular. These are so formed that the sectional shape 4' obtained by mutually fusion bonding the flat parts of the semicircular optical fibers in which the sectional shapes of the two fibers are nearly semicircular is nearly circular in which the two cores 31', 32' are contained. Hence, the change in the sectional shape after the fusion bonding is less and the deformation of the cores is slight and therefore the losses are low and the characteristic change owing to aging does not occur.
