摘要： After making such adjustment that an a main push-pull signal MPP offset can be made zero when a main beam is positioned at the center of a main photoreceptor, using electric signals E and F photoelectrically converted by one of two two-divided side beam photoreceptors and electric signals H and G photo-electrically converted by the other thereof, a side push-pull signal SPP including a constant α is determined for allowing respective (F−αE) and (αH−G) offsets to be made zero and is calculated according to the formula, SPP−(F−αE)+(αH−G). From this SPP signal and the main push-pull signal MPP, a differential push-pull signal DPP is then calculated, thereby allowing stable tracking control to be carried out, even during recording.

摘要： A plurality of stages of parallel twisted plates extend in a slurry passage adjacent to a slice outlet of a head box in the direction of papermaking slurry flow therethrough and are spaced apart from each other by a predetermined distance. The twisted plates directly cause the slurry flowing through the head box to swirl. Adjacent vortex flows of the slurry interfere with each other, resulting in the violent agitation of the slurry.

摘要： A brushless motor comprises a magnet having a plurality of pole faces, a plurality of conductors mounted adjacent to the pole faces, and a plurality of phase coils connected together at a neutral point. The magnet is included in the motor rotor and the phase coils are included in the motor stator. A high-frequency signal source supplies a high-frequency signal to the neutral point, whereby changes in eddy current loss and thus the position of the rotor with respect to the stator are detected.
