    摘要： A process for preparing a fluorine-containing copolymer by an emulsion polymerization method in the presence of aqueous ammonia as a pH modifier, and a molded article obtainable by melt molding or crosslinking molding the fluorine-containing copolymer. In preparing the fluorine-containing copolymer by coagulation of the fluorine-containing copolymer contained in a fluorine-containing copolymer dispersed aqueous solution, it is preferred to use a cationic surfactant and a water soluble organic solvent as a coagulating agent used for the above coagulation. The surfactant is preferably represented by the, formula (R4N+)X− wherein R is an alkyl group of 1 to 22 carbon atoms, a fluoroalkyl group obtainable by fluorine substituting at least a part of hydrogen atoms present in the above alkyl group or hydrogen, four R's may be the same or different provided that they are not hydrogen atoms simultaneously, and X is a halogen atom. The process for preparing a fluorine-containing copolymer provides a decrease in a concentration of metal elements, which act as an impurity source, for example, having a metal element concentration of not more than 1 ppm.

    摘要： An electronic noise attenuation system for attenuation of non-steady noise occurring in a propagation passage such a duct line by conducting adaptive controls by use of a computer system including a digital filter therein. Sensing microphones M.sub.1, M.sub.2 are located in the propagation passage with a cancellation sound source S therebetween at positions where the transfer functions Hr, Ht of a sound wave generated from the cancellation sound source are equivalent to each other. The output signal of the sensing microphone M.sub.1 and the phase-inverted version of the output signal of the sensing microphone M.sub.2 are input via an add circuit to the control part of the system. The system can prevent the occurrence of an acoustic feedback from the cancellation sound source to the sensing microphone M.sub.1 so as to realize a stable and highly accurate noise attenuation.
