摘要： A driving device includes a motor, and a gear housing secured to the motor. The gear housing accommodates reduction gears. Rotation of the motor is reduced by the reduction gears before being transmitted to an output shaft supported by the gear housing. A support cylinder extends from an outer surface of the gear housing to support the output shaft. A surrounding cylinder extends from the outer surface of the gear housing to surround the support cylinder. Reinforcing ribs are located between the support cylinder and the surrounding cylinder. Each reinforcing rib extends from a circumferential wall of the support cylinder such that the angle between the reinforcing rib and a normal line that intersects the circumferential wall form a predetermined angle. Each reinforcing rib has a radially inward end connected to the support cylinder and a radially outward end connected to the surrounding cylinder.

摘要： The invention relates to a method of activating an optical communication system comprising a plurality of optical amplifiers having an optical amplifier, between optical transmission lines in which wavelength-division multiplex optical signals are transmitted. The method comprises steps of: generating a desired slope in a desired wavelength range of a gain wavelength curve of the optical amplifier; adjusting an output of the optical amplifier to a desired output level; performing the above two steps in a plurality of optical repeater stations, the steps being carried out in sequence from the first to the last optical repeater stations; and adjusting a level in each optical signal in the wavelength-division multiplex optical signal so as to have substantially constant optical signal-to-noise ratios in the optical signals to be received. Activating the optical communication system according to this procedure allows proper execution of gain slope compensation, output control, and pre-emphasis control.

摘要： An optical amplifier relates to WDM (wavelength division multiplexing). The optical amplifier includes an optical amplifying unit, an ALC (automatic output level control) circuit for controlling the unit based on the output level thereof, and AGC (automatic gain control) circuit for controlling the unit based on the input and output levels thereof. A selecting circuit alternatively selects and operates the ALC and AGC circuits in accordance with a predetermined rule. Accordingly, the inconvenience occurring in the case of performing only one of ALC and AGC can be eliminated.

摘要： A tubular extrusion molding product comprising a high molecular weight polyarylene sulfide having a melt viscosity of from 3,100 poise to 60,000 poise produced by reacting an alkali metal sulfide and a dihaloaromtic compound in the presence of an organic amide solvent, cooling a gaseous phase part in the reaction zone during the reaction thereby condensating at least a part of the gaseous phase and refluxing the resultant condensate to a liquid phase in the reaction zone. A tubular extrusion molding product having further improved impact resistance can be provided by copolymerizing from 0.2 mol % to 1 mol % of a polyhaloaromatic compound to the alkali metal sulfide. A tubular extrusion molding product of improved impact resistance is provided by further applying a heat treatment of the polyarylene sulfide intermediate product thereby increasing the melt viscosity.

摘要： An automatic temperature control circuit of a laser diode solves a problem that a temperature control becomes unstable when switching to heat or cool the laser diode. In the circuit, a peltier element changes the temperature of the laser diode by heating or cooling, a temperature detecting section detects the temperature of the laser diode and outputs the corresponding detected voltage, an error amplifying section outputs an error voltage by comparing the detected outputted voltage with a fixed value, a peltier current control section controls the direction of a driving current flowing to the peltier element in correspondence with an error voltage outputted from the error amplifying section. In addition, there is provided a circuit which feed-backs a voltage corresponding to the driving current flowing to the peltier element to an input side of the error amplifying section and adds it to the detected voltage outputted from the temperature detecting section.
