Patent JP-H0515914-A (JP)
Title: Controller for rolling tension
Inventor: KATORI HIDEO
IPC: B21B37/48
Filed: 1991-07-10
Abstract: PURPOSE:To provide a device for detecting and refraining even comparatively small variation of tension and preventing tension control systems of plural stands from interfering and oscillating. CONSTITUTION:The tension control systems for correcting draft positions in response to detected tension deviations are provided. A tension control system having a blind sector and a tension control system having no blind sector are arranged alternately. Since the change of downstream tension by correcting rolling down of the latter is within the range of blind sector of the former, the former does not respond to the change and no interference is generated between the stands. Even small tension deviation is corrected by the latter control system.

Title: Fusion splicing method of optical fiber and device therefor
Inventor: HINO RENKAI
IPC: G02B6/255
Filed: 1994-06-29
Abstract: PURPOSE:To provide a fusion splicing method of optical fibers which is capable of placing bare optical fibers in the corresponding V-grooves of V-groove blocks without requiring skill at the time of setting coated fiber fixtures at a moving table and placing the bare optical fibers in the V-grooves and preventing contact of the front ends of the bare optical fibers with the V-grooves at this time and a device therefor. CONSTITUTION:The respective coated fiber fixtures 6 fixed with coated optical fibers 1A, 1B are respectively set on the moving table 11 of the fusion splicing device before the bare optical fibers 2A, 2B are placed in the V-grooves 4 for alignment of the V-groove blocks 3A, 3B; thereafter, the moving table 11 is at least partly moved to move the front ends of the bare optical fibers 2A, 2B downward together with the coated fiber fixtures 6 on the moving table 11, by which the bare fibers 2A, 2B are placed in the V-grooves 4 for alignment in the state that the front ends thereof cross the V-grooves 4 for alignment. As a result, the bare optical fibers 2A, 2B do not move by coming into contact with the V-grooves 4 and, therefore, the adhesion of foreign matter at the front ends of the bare optical fibers 2A, 2B do not arise and the damaging of their front ends does not arise either. The fusion spliced part of the optical fibers is thus connected in a good state.

Title: Stripe shaped type double hetero junction laser element
Inventor: UENO MASASUKE
IPC: H01S5/24
Filed: 1980-12-05
Abstract: PURPOSE:To maintain a stable horizontal oscillation with a low threshold current by providing a stripe-shaped guide layer having a projection that thins out at ends with a smaller refractivity than an n type active layer whereby covering the both sides of the guide layer by a p type clad layer with a part buried in an n type clad layer. CONSTITUTION:A V shaped groove 12 is formed in p-InP11 on n-InP10 and n- InGaAsP13 is formed covering the groove. An n-InGaAsP active layer 14 and a p-InP clad layer 15 are laminated to cover SiO216. A Cd diffusion layer 17 is formed by opening a stripe shaped window including the V-shaped groove 12 and a p type ohmic connection layer 18 and an n n ohmic connection layer 19 are formed on the layer 17. This current narrowing construction contributes effectively to the oscillation of the injected carrier, lowering the threshold current and maintaing stable elemental mode oscillation due to the convergence of light to the center caused by a smaller refractivity toward the ends. This also decreases a flare angle in vertical direction making the light source of almost concentric circles and increasing the coupling efficiency with fiber and also preventing the leak of carriers from the active layers.
