摘要： An echo cancelling system, in which a pseudo-echo is provided by producing an impulse response of an echo path, reversed in phase and then applied to a subtractor of the echo path to cancel an echo. A low level reference signal, such as random noise or an artificial random signal, is continuously applied to the echo path and successively delayed by a sampling period to obtain a plurality of delayed reference signals, which are multplied by the output of the subtactor to obtain a plurality of multiplied outputs. The multiplied outputs are integrated by integrators and then amplified by high gain amplifiers to be employed for producing the psuedo-echo. As a result of such construction of the adaptive control loop, the convergence time for cancellation is effectively improved.

摘要： A simple-structured non-contact-guidable magnetic floating device which has stable restoring forces in vertical and horizontal directions perpendicular to the direction of guiding the moving member. At least one inner magnetic member is formed so that magnetic poles are continuously arranged lengthwise thereof. Two outer magnetic members are disposed on both sides of the inner magnetic member in adjacent but spaced relation thereto and formed so that magnetic poles are continuously arranged in a lengthwise thereof. A non-magnetic coupling member is provided apart from the inner magnetic member, for coupling together the two outer magnetic members. A support is provided for supporting and fixing one of the inner and outer magnetic members. The other of the inner and outer magnetic members is held in a floating state in which it has restoring forces to its center positions in vertical and horizontal directions, by magnetic attractive forces between the inner and outer magnetic members or a combination of their magnetic attractive and repulsive forces, and the other magnetic member can be guided lengthwise thereof in the floating state.

摘要： A noncontact magnetic bearing has cylindrical magnetic members magnetized axially, slightly different in radius and different in length, disposed in opposite relation to each other, with their magnetic poles of reverse polarities displaced vertically relative to each other. Either the inner cylindrical magnetic member or the outer cylindrical magnetic member can be used as a shaft, and consequently, the other is fixed to a support member. The inner cylindrical magnetic member and the other cylindrical magnetic member are held at a stable and mutual-noncontact state to provide a noncontact magnetic bearing that is stable axially, as well as radially.
