    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： The invention, relates to a method for optical fiber communication. An optical signal having chirping determined by a chirp parameter is output to an optical fiber transmission line. The optical signal transmitted by the optical fiber transmission line is converted into an electrical signal. A bit error of the electrical signal is detected. Then, the chirp parameter is controlled so that the bit error detected above is reduced. According to this method, the chirp parameter is controlled so that the bit error detected is reduced. Accordingly, a chirping occurring in the optical fiber transmission line can be suppressed by the chirping of the optical signal to be output to the optical fiber transmission line, thereby compensating for chromatic dispersion and nonlinearity.

    摘要： An analog-to-digital converter arranged to accept an analog input signal and to convert it into an output having digital form. The converter is characterized by a reference random noise source which generates random noise signals with uniform amplitude occurrence probability density in a given range, and by an amplitude comparator arranged to repeatedly compare the amplitude of the random noise signal with the amplitude of a signal varying with the analog signal to be converted. The amplitude comparator supplies output pulses in accordance with the comparisons, e.g., whenever the analog signal amplitude is greater than the random noise amplitude, and the number of pulses from the amplitude comparator in a measurement interval then digitally corresponds to the value of the analog signal and may be utilized, as in a display. Resolution of the converter is increased beyond the minimum amplitude increment of the random noise source signal in one embodiment by superposition on either the analog signal or the random noise signal of a triangular wave with an amplitude greater than the minimum amplitude increment of the random noise signal, and in another embodiment by superposition of a second random noise signal.

    摘要： The invention provides a wavelength multiplexing transmission apparatus includes a plurality of optical signal outputting sections for outputting optical signals having different wavelengths from each other, and a wavelength multiplexing section for wavelength multiplexing the optical signals outputted from the optical signal outputting sections and sending out a resulting optical signal. Each of the optical signal outputting sections includes a transmission light source driven by an electric signal for outputting an optical signal of a predetermined wavelength, and a wavelength filter capable of passing therethrough and sending out only an optical signal of the predetermined wavelength to be outputted from the transmission light source to prevent a wavelength drift of the optical signal outputted from the transmission light source. A variation of the wavelength of the transmission light source is detected, and the transmission light source is shut down in order to prevent otherwise possible crosstalk with another channel and prevent a further influence of the same.
