Appeal No. 1997-0397
Application 07/863,900
series with said winding turns during energization thereof
whereby the power output of a given hardware assembly may be
preselectively determined, at the time of manufacture and
interconnection with the control circuit by the capacitance
value of said capacitor in the control circuit.
The Examiner relies on the following prior art:
Sato 4,600,864 July 15, 1986
Gerfast 4,929,871 May 29, 1990
Claim 66 stands rejected under 35 U.S.C. § 103 as being
unpatentable over Sato and Gerfast. The rejection is stated in Final
Rejection (Paper No. 16). The Examiner finds that Sato discloses a
brushless DC motor essentially as claimed except for providing a
capacitor in series with the motor winding. The Examiner finds that
Gerfast discloses, at column 2, lines 36-41, providing a control
circuit having capacitor in series with the winding of a brushless DC
motor, where the size is selected to match the load, and observes
that the capacitor 28 (figure 2) in Gerfast is connected between the
AC input and the rectifying portion of the motor drive circuit just
as capacitor 127 is connected between the AC input and the rectifier
128 in Appellants' invention. The Examiner concludes that it would
have been obvious to provide a capacitor in series with the motor
winding of Sato in order to control the amount of current supplied to
the motor, as disclosed by Gerfast. The Examiner further reasons
