Title: Optical polarized wave transmitting system
Inventor: MACHIDA SUSUMU
IPC: H04B10/516
Filed: 1981-05-25
Abstract: PURPOSE:To make the outputted polarized light stable and to obtaind transmission characteristics with high quality, by twisting a single mode optical line equal to or more than the minimum twist rate, in a transmission system using  the single mode optical line. CONSTITUTION:A light from a light source can be interfered 10 with linear polarization is modulated at an optical transmission section 9 with a signal from an incident terminal 11. This optical signal is transmitted on a single mode optical line 14 twisted equal to or more than the minimum twist rate phit0 and  given to a optical reception section 15. Since the incident linearly polarized light is obtained at an emission end 16 of the line 14 with twist, and not obtained as an elliptically polarized light, no phase compensation is required and the loss to the optical reception signal can be reduced. Further, to coincide the polarized angle at the output terminal 16 of the line 14 to be twisted with the polarized angle of a local oscillating light source 17, it is done by changing the polarized angle of the local oscillation light source 17 and the efficiency of detection can not be decreased. Further, since the deterioration of white light polarization is less, the generation of twist and noise are lessened.

Filed: 1986-04-08
Abstract: PURPOSE:To obtain an optical fiber provided with uniform quality and good light transmission characteristic by using a sleeve component polymer from which the low-mol.wt. material incorporated therein as a sleeve component is removed by solvent extraction. CONSTITUTION:The sleeve component polymer produced by a stage for removing the low-mol.wt. material incorporated as the sleeve component into the sleeve component polymer by solvent extraction is used at the time of producing the optical fiber by extruding and uniting the sleeve component consisting of a thermoplastic polymer to the circumference of a core component. The chemical compsn. of the sleeve component to be used has particularly preferably the refractive index smaller by >=0.01 than the refractive index of the core component. The refining of the sleeve component polymer is executed by stirring, mixing and filtering the polymer in a poor solvent for said polymer, by which the low-mol.wt. material incorporated into the polymer is removed. The low-mol.wt. material incorporated into the sleeve component polymer is eluted into the poor solvent by such treatment stage and therefore, the low-mol.wt. material is approximately thoroughly removed by further cleaning the polymer filtered from the poor solvent with the poor solvent.

Abstract: PURPOSE:To enable a swimmer to be propelled under water in any direction with any speed by providing a submarine pump, at least one nozzle connected to the pump to jet water, a device for adjusting water flow to the nozzle and further a nozzle mounting angle changer. CONSTITUTION:This propeller introduces water from the bottom of a submarine pump 2 driven by a battery 3 and jets the water from a nozzle 5 through a water conduit 5 to generate a thrust. A swimmer puts the side of the propeller opposite to the nozzle side on his back and carries the propeller on his back by means of a fixture to advance with the reaction of jet as a thrust. Also, the vertical and horizontal directions of the thrust are changed by operating a nozzle direction guide 6 with electric power from the battery to change a nozzle mounting angle, and the propelling angle is changed by adjusting flow from the submarine pump. Both propelling direction and speed are changed by the swimmer's operation of a switch. When the moving range of the swimmer is limited, electric power in place of the battery may be supplied from on the ground through a wire to drive the pump and nozzle.
