摘要： A drive rotation member is driven by a crankshaft of the engine, and a driven rotation member is rotatable relative to the drive rotation member and secured to a cam shaft of the engine. An electric motor is arranged to rotate together with the drive rotation member and produces a dynamic power when fed with an electric current through brushes. A hollow control shaft is rotatable relative to the drive rotation member and forces the driven rotation member to rotate relative to the drive rotation member when rotated by the power of the electric motor. A bearing device is arranged between the driven rotation member and the hollow control shaft for smoothing a relative rotation therebetween. The bearing device includes a plurality of rollers. A lubrication oil feeding structure is provided for causing the rollers of the bearing device to be submerged in a lubrication oil at least when the engine is in operation.

摘要： In a valve timing control apparatus configured to execute phase-control via a phase converter, a controller is configured to control a phase angle of a camshaft relative to a crankshaft during an engine stopping period to a target phase angle differing from a required phase angle suited for an engine operating condition. The controller is further configured to change the phase angle of the camshaft toward the required phase angle during a time period from a point of time when cranking starts to a point of time when detection of a rotational position of the camshaft initiates during an engine restarting period. The controller is still further configured to start feedback-control for the phase angle of the camshaft from the point of time of initiation of detection of the rotational position of the camshaft for bringing the phase angle of the camshaft closer to the required phase angle.

摘要： To remove the echo of a received signal from a local input signal, an echo canceler adaptively estimates the transfer characteristics of the echo path. When a double-talk condition is detected, the echo canceler reverses the adaptation process and returns to a set of estimated transfer characteristics that were in use before the double-talk condition began. Imperfect echo cancellation due to incorrect estimation caused by double-talk is thus prevented inexpensively.
