Title: Method for removing coating of coated optical fiber
Inventor: ARIMA TADAO
IPC: G02B6/24
Filed: 1991-04-25
Abstract: PURPOSE:To sharpen the boundary between a part where a coating is removed and a part where the coating remains and to decrease the fluctuations in coating length as well as to obviate the degradation in the strength of the optical fiber by irradiating the coated optical fiber with a YAG laser beam to melt the secondary coating material of the fiber and blowing gas thereto to blow off the molten coating material. CONSTITUTION:The prescribed point of the coated optical fiber 1 to be subjected to the removal of the coating is irradiated with the YAG laser beam 15 by which the secondary coating material 4 is heated to melt. While the molten coating material 4A is blown off by ejecting the gas 25 from a nozzle 20, a laser emission optical system 11 and the nozzle 20 are moved by as much as the length to be removed along the coated optical fiber 1, by which the secondary coating material 4 is removed. The optical fiber 2 and the silicone coating layer 3 do not absorb the YAG laser beam and are, therefore, not heated up to the melting temp. of the secondary coating material 4 or above and the silicone coating layer 3 remains on the optical fiber 2 side. The optical fiber is stored in this state and the silicone coating layer 3 is removed by rubbing the layer with fingers just before the fiber is made into, for example, a fiber fusion type optical coupler.

Abstract: PURPOSE: To achieve an efficient utilization of motor power by installing a control mechanism between a fixed flange and a movable flange which are able to take an axial displacement relative to each other, adjusting distance between these flanges in response to the rotational frequency.  
     CONSTITUTION: A pulley 3 consists of a pair of side plates 3a, 3b which form an out-opening taper 3c at their outer circumference with a belt 6 held therein.

While the side plate 3b is fixed to the shaft 1' through another stopper 22, the side plate 3a is always pushed upward by means of a spring 23. Balls 21 are shifted towards radial direction due to centrifugal force imposed upon the balls 21 in response to the rotational frequency of shaft 1', and thus the effective diameter of the pulley 3 is properly adjusted.
