IPC: C03C25/10
Filed: 1986-12-24
Abstract: PURPOSE:To suppress a change in the Young's modulus of a layer of a water absorbing ultraviolet-curing org. polymer having >=1wt.% water absorbing capacity on a quartz glass-base optical fiber by forming a layer of a water impermeable org. polymer on the water absorbing polymer layer. CONSTITUTION:A primary coating layer 2 and/or a secondary coating layer 3 on an optical fiber 1, especially the secondary coating layer 3 is made of a water absorbing ultraviolet-curing org. polymer and a water impermeable layer 4 is formed on the layer 3. The layer 4 is made of a water impermeable org. polymer. The water absorbing capacity and water permeability of the water impermeable polymer are <=1/5, preferably <=1/10 of those of the water absorbing polymer. Ultraviolet-curing fluororesin or polyvinylidene chloride may be used as the water impermeable polymer. Even when the relative humidity of an atmosphere in which the optical fiber is used undergoes a change, the diffusion of water into the water absorbing polymer layers 2, 3 is effectively hindered, so a change in the Young's modulus of the layers 2, 3 due to a change in the relative humidity can be suppressed.

IPC: D05B19/16
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To make exchanging and supplying consumable materials simpler and to make the size of the device smaller, by moving a support body to a prescribed exchanging position by a control means when consumable materials are to be exchanged or supplied. SOLUTION: When the residual amount of thread of a bobbin 24 in a cassette 25 of an arm part 23 is detected and the residual amount is judged to be small, a control circuit 10 interrupts sewing work, and the arm part 23 is moved to and positioned at a prescribed cassette exchanging place 35. Thereby a worker is brought into a state to easily exchange cassettes 25. Then a cassette 25 with small amount of residual thread mounted on the arm part 23 is replaced by a new cassette 25a. At that time, when an upper thread residual amount detecting means judged the residual amount of thread in the cassette 25 a is sufficient, the control circuit 10 restores the arm part 23 to the position before sewing work interruption and restarts sewing work. Thus another arm part for refilling is made unnecessary to make upper thread supply simpler and the device smaller.

Title: Conductive roll
Inventor: HAMADA KOICHI
IPC: C21D9/56
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To avoid the unstable contact caused by the defective shape of a metallic strip and to prevent the development of spark by forming the whole width of a conductive roll at more narrow than the width of the metallic strip. SOLUTION: The conductive roll 1 at high temp. side or the conductive roll 2 at low temp. side is connected with an electric source 6 through a sliding brush part 9 arranged in a roll shaft 8. The whole width LG (effective contacting area except the round corner part at the edge parts) of the single type rolls 1, 2 in the figure (b) is made to L < W to the width W of the metallic strip 5. By this constitution, 'burr' developed with rod-cutting and trimming is avoided, and the contact between the roll and metallic strip is secured and the development of the spark can be prevented. In order to avoid the effect of thermal crown, the roll can be divided into plural parts, such as the figure (c). In such a way, the thermal crown is reduced to each unit roll and the contact with the metallic strip becomes good.  Even in such a case, in order to avoid the burr, the whole width LG is necessary to be more narrow than the width W of the metallic strip, too.
