    • A process is provided for preparing a polycarbonate composition with excellent weatherproof properties. The process comprises adding an ultraviolet absorbing compound having a hydroxy group which contributes at least partially to the molecular weight modifier to an oligomeric polycarbonate which is obtained by the reaction of a dioxy compound with phosgene, and then condensing said oligomeric polycarbonate to polymerize the same. The invention also concerns a process for preparing a polycarbonate with excellent weatherproof properties which process comprises introducing a dioxy compound in alkaline solution and an organic solvent for the polycarbonate into a tubular reactor continuously to form a turbulent flow, feeding phosgene concurrently to the reactor with cooling outside of the reactor to produce an oligomeric polycarbonate as the solution of organic solvent, adding an aqueous alkaline solution of dioxy compound, molecular weight modifier, which is contained at least in part ultraviolet absorbing compound having an hydroxy group, and catalyst selected from the group consisting of tertiary amine and quaternary ammonium salt and, if desired, antioxidant to said oligomeric polycarbonate solution and condensing said oligomeric polycarbonate to polymerize the same.

    • There is provided an amplifier that achieves stable distortion compensation without using a pilot signal even when there is a difference in level in the base signal of a multicarrier signal. The amplifier is a feedforward amplifier for amplifying a multifrequency wideband signal without using a pilot signal, and includes an input monitoring section in a signal input stage and an output monitoring section in a signal output stage, whereby for fluctuations in level of the signal from the monitoring sections, when the signal level is decreased to cause a significant decrease in the level of adjacent channel leakage power (ACP) and when the signal level does not decrease to cause a slight increase in ACP level, the controller shifts a set ACP reception frequency to an opposite frequency of the multicarrier signal, thereby achieving stable distortion compensation even when there is a difference in level in the base signal of a multicarrier signal.
