Appeal No. 1998-1078 Page 11
Application No. 08/442,532
Because the examiner fails to show a relationship between
the torque ripple of a brushless motor and the motor's trigger
point, we are not persuaded that the prior art would have
suggested that "relative positions of said stator core, said
driving magnet pole portion, said FG magnetized portion, and
said FG pattern in a circumferential direction are set so that
a minimum point of a torque ripple of said brushless motor
always occurs at a different time than a point of an output
signal from said FG pattern, said point of said output signal
functioning as a trigger for rotation control" or that the
"relative positions ... are set so that a maximum point of a
torque ripple of said brushless motor always occurs at the
same time as, a point of an output signal from said FG
pattern, said point of said output signal functioning as a
trigger for rotation control." Therefore, we reverse the
rejection of claims 1-4 as obvious over AAPA in view of Imai.
