enable signal. Consistent with the fourth interpretation
above, we interpret that this time period is not limited to
the last three time periods in Figure 6, but reads on any two
exciting time periods within the enable signal interval and a
non-exciting time period after termination of the enable
signal interval when the current goes to zero.
The sixth interpretation involves the following
limitation in claim 7: "when the exciting current of said
stepping motor is restored during an enable excitation time
interval beginning from application of said step signal."
Consistent with the fourth interpretation above, we interpret
that this time period is not limited to the first three time
periods in Figure 6, but reads on any three exciting time
periods within the enable signal interval.
The seventh interpretation involves the following
limitation in claim 8: "when the exciting current is applied
to said stepping motor during an enable excitation time
interval beginning from application of said step signal."
Consistent with the fourth interpretation above, we interpret
that this time period is not limited to the last three time
periods in the enable signal interval in Figure 6, but reads
