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
