motor can be braked in the right direction. Therefore, Aoshima
does not use clock pulses to activate a tach braking circuit to
brake the motor when the speed of the motor has been determinated
to have slowed to an actual predetermined spinning velocity.
We agree with Appellants’ assertion (brief, page 8) that
the combination of Sander, Davie and Aoshima fails to teach or
suggest using clock pulses to activate a tach braking circuit to
brake the motor. As discussed above, none of the references
recognize the importance of “activating a tach braking circuit to
brake the motor by using clock pulses” when the motor is
determined to have reached a set velocity. Therefore, contrary
to the Examiner’s position, using clock pulses for activating a
tach braking circuit, as recited in claim 1, cannot be derived
from the combination of the references.
In view of our analysis above, we find that the Examiner has
failed to set forth a prima facie case of obviousness with
respect to claim 1 because the necessary teachings and
suggestions related to the claimed use of clock pulses are not
shown. We note that independent claims 7 and 15 include similar
limitations related to “a tach braking circuit to brake said
