Appeal No. 1997-4445
Application 08/305,076
Br6: "time period tc is not an exciting time period, since it
occurs after the end of the exciting current enable signal").
The second interpretation involves the limitation in
claim 6 about "(iii) further to decrease the exciting current
to zero during a third exciting time period" (emphasis added).
This limitation is misdescriptive under 35 U.S.C. § 112,
second paragraph, because the current in Figure 6 clearly
decreases to zero after the termination of the exciting
current enable signal during a time period which is not an
exciting time period just as the exciting current in the APA
of Figure 1 decreases to zero during non-exciting time period
tc. See Br6: "time period tc is not an exciting time period,
since it occurs after the end of the exciting current enable
signal." A new ground of rejection is entered infra.
The third interpretation involves the limitation in
claim 6 about controlling the exciting current supply circuit
"when the exciting current supplied to said stepping motor is
cut off at a termination of an enable excitation time interval
beginning from application of said step signal." This
limitation is misdescriptive under 35 U.S.C. § 112, second
paragraph, because the term "when" indicates the three
