摘要： An optical transmission device which is used for a short range optical data link or an optical communication system for subscribers and more particularly requires no automatic optical power control minimizes the turn-on delay time of a laser diode and allows unformatted optical signal transmission by fixed level decision receiving system. By applying a fixed-bias electric current which is not more than the electric threshold current value of the laser diode to the laser diode, the turn-on delay time of the laser diode can be minimized, and the extinction level can be lowered by it, and the fixed level decision receiving system can be used, and the optical receiver circuit can be simplified more.

摘要： A regeneration process in the operating method of the invention includes a first regeneration process, and a second regeneration process after the end of the first regeneration process. In the first regeneration process, a regenerant is distributed at a top of an ion exchange resin bed and simultaneously the regenerant is collected at a bottom of the resin bed, thereby generating a downward flow of the regenerant to regenerate the whole of the resin bed. In the second regeneration process, the regenerant is distributed at a bottom of the ion exchange resin bed and simultaneously the regenerant is collected at a middle of the resin bed, thereby generating an upward flow of the regenerant to regenerate a part of the resin bed.
