Title: Fiber optic links and method for eliminating optical power limitation due to stimulated raman scattering in fiber optic links
Inventor: BLONDEL JEAN-PIERRE
IPC: H04B10/2537
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a fiber optic link for lowering limitation to signal or pump sending power due to stimulated Raman scattering by using attenuator means in the Raman gain region. SOLUTION: Various techniques are proposed for limiting stimulated Raman scattering. In particular, the use of optical fibers 96 and 100 which are lightly- doped with dysprosium, the attenuation of which increases rapidly beyond 1,500 nm, is proposed. The use of this fiber for transporting the pump powers 94 and 98 at 1,480 nm toward the remote amplifiers 84 and 88 enables injection of pump power up to about 10 W, as compared to the current limit of 1.3 W. This technique enables the range of the links to be increased by approximately 80 km.

Abstract: PURPOSE:To eliminate wasteful use of a ribbon at the time of a non-printing operation such as spacing or tabulation, by supplying a ribbon to a printing head only when a carrier is moved with a printing operation. CONSTITUTION:When the printing head 29 is in a printing condition, a restraining lever 81 presses a guide receiving part 79 of a cassette 72 by a tension spring, thereby clamping and restraining the ribbon 32. Therefore, when the ribbon 32 is pulled concurrently with a rightward stepping motion of the carrier 21 in this condition, a supplying reel 73 is rotated to let out an unused part of the ribbon 32. On the other hand, when the head 29 is at a non-printing position, a restraining lever 33 restrains the ribbon 32 by clamping it between the lever 33 and a guide body 39. Therefore, when the carrier 21 is moved rightward and the ribbon 32 is pulled in this condition, the ribbon is let out from both a take-up reel and the supplying reel, but the unused part of the ribbon is not displaced, so that it is not supplied to the head 29.

Abstract: PURPOSE: To suppress the potential rise of photosensitive material by electrically insulating the respective electrodes and power sources of the 1st and 2nd chargers from others, connecting the shield electrodes of the both chargers and connecting the power source to each discharge electrode and shield electrode.  
     CONSTITUTION: Discharge electrodes 11, 11' are connected like 13, 13' by power sources 12, 12' and between the respective shields 10, 10' are also connected like 14. Further the connections between the shields 10, 10' are connected by a connection 15 commonly to two kinds of power sources 12, 12'. Two kinds of power sources 12, 12' and shield electrodes 10, 10' are electrically insulated from the ground. Electrically insulating the shield electrodes from other members allows electrode potentials to fluctuate freely and floating the power sources makes possible the compensation of the mutual current amounts with each other. Such constitution enables the controlling without requiring means such as of detecting the balance of discharging of the 1st charger and the suppression of the rise of residual potential in the image background part of the photosensitive material having an insulation layer.
