    摘要: An active noise controller can determine the signal transmission characteristics from the power amplifier and the speaker to the microphone without using any special external measuring instrument and calculate a cosine correction value and a sine correction value without using an external computer. The active noise controller uses the cosine correction value and the sine correction value to actively reduce vibrational noise. The measurement mode is selected on touch panel (3), and correction value calculator (22) calculates cosine correction value C0 and sine correction value C1 by using filter coefficients W0 and W1 which allow error signal e′(n) to approach zero. Memory (23) stores these values C0 and C1.

    摘要: The present invention provides a chlorine-containing polymer vulcanizing composition with improved preservation stability. The present invention is a chlorine-containing polymer vulcanizing composition obtained by blending (a) a zeolite compound, (b) a vulcanizing agent, and (c) an optional organic vulcanization accelerator. The zeolite compound can be natural zeolite, an A-type, X-type, or Y-type synthetic zeolite, a sodalite, natural or synthetic mordenite, ZSM-5, or a metal substitution product thereof. The zeolite compound is preferably an activated zeolite compound. With respect to 100 parts by weight of chlorinated polyethylene, (a) preferably 0.5 to 30 parts by weight, more preferably 5 to 25 parts by weight, of the zeolite compound, (b) preferably 0.1 to 5 parts by weight, more preferably 0.5 to 3 parts by weight, of the vulcanizing agent, and (c) preferably 0.5 to 3 mol, more preferably 0.7 to 1.5 mol, of the vulcanization accelerator with respect to 1 mol of (b) the vulcanizing agent are blended.
