Appeal No. 1997-3237 Application 08/266,081 either the regeneration current or the state of battery charge. The Examiner on page 2 of the supplemental answer states that Takada in col. 6, lines 27 and 28 discloses the step of detecting the current supplied to the motor being related to the variation in charge of the battery. The Examiner further states that such battery charge detection in terms of regeneration current flowing to the battery is inherent in the regeneration mode. We find that claim 6 requires that the operation of the motor at the second point with reduced efficiency be in response to both a “regeneration current flowing into the battery” and a “state of charge of said battery.” Takada in col. 7, lines 35 through 44 teaches a deceleration apparatus for a motor where a part of the regenerated power is absorbed in a resistor and the rest is returned to the power source. Takada in col. 9, lines 24 through 47 further discloses that when the regeneration current is directed to the power supply, a specific timing imposed by the rotation speed control circuit 1 causes the motor to change from a first low efficiency intermittent regeneration mode to a second higher 12Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
