Patent CA-2001393-A1 (CA)
IPC: F16D27/112
Filed: 1989-10-24
Abstract: In an electromagnetic clutch comprising a plurality of leaf springs for supporting an armature plate (18) to a shaft (14) so that the armature plate (18) faces a pulley (16) in an axial direction with a gap left therebetween, each of the leaf springs has a substantial length which is adjusted in response to a size of the gap. This results in changing of a spring constant of each of the leaf springs. When the armature plate is moved towards the pulley, the size of the gap becomes gradually small. Simultaneously, the armature plate is subjected to a suction force which acceleratingly increases in response to decreasing of the size of the gap. However, it is possible to reduce a noise which is generated when the armature plate is attracted to the pulley. This is because the armature plate comes into soft collision with the pulley.

Patent CA-2013071-A1 (CA)
IPC: H03H21/00
Filed: 1990-03-26
Abstract: Disclosed is an adaptive canceler (32) in which a pipelined approach is used wherein reference signals are divided  into two or more  sections having  concurrent weight adjustment.   This architecture allows the speed of adaptive  cancellation to be  increased  and/or the number of reference taps to be increased without loss of cancellation speed.  Once a continuous stream of digital data has been established  in this  architecture,  the speed of  the adaptive  processor  is  limited  only  by approximately  the  processing  time  of  the  slowest element.    The  noise  canceled  signal  may  then  be converted to the  frequency domain in a  fast Fourier transform device (34).
