Abstract:
It is intended to provide a treating agent for elastic fibers which can give an elastic fiber excellent in antistatic properties, fibrillation properties, cheese winding form and smoothness, lessens cotton dust adsorption in the step of cross-knitting the elastic fiber with cotton yarns and thus enables high-speed knitting of fine elastic fiber with cotton yarns and elastic fibers having been processed with the treating agent. Namely, a treating agent for elastic fibers which comprises 60 to 99.99 parts by weight of at least one member selected from among silicone oil, mineral oils and ester oils as the base component together with from 0.01 to 20 parts by weight of an amino-denatured silicone and from 0.0001 to 20 parts by weight of a phosphoric acid ester having at least one hydrocarbyl group or oxyalkylene group per molecule. Elastic fibers characterized by having from 0.1 to 15% by weight of the above-mentioned treating agent imparted thereto.

Abstract:
The preset invention relates to a system for controlling sounds and images through three-dimensional matrix circuit, which outputs voice and sound signals outputted from a sound generator and amplified by a plurality of amplifiers through a plurality of speakers. The system includes a matrix circuit and a controller. The matrix circuit is configured in a three-dimensional type such that the amplifiers and the speakers to which the voice and sound signals outputted from the sound generator are delivered are connected to each other, changing and adding input/output according to a user's selection. The controller controls various kinds of operations of the speakers and the amplifiers by allowing a user to control the matrix circuit by a multicast method so as to select amplifiers or a combination thereof to be used for broadcasting using a keyboard or a mouse.
