exciting time periods of limitations (i)-(iii) take place
after the termination of the enable excitation time interval.
However, the time first two time periods of (i) and (ii) take
place before the enable signal is terminated. A new ground of
rejection is entered infra.
The fourth interpretation involves the functions (i)-
(iii) in claims 6-8. The claims are open ended and the
limitations do not preclude other time periods from occurring
in between the first, second, and third exciting time periods.
That is, limitations (i)-(iii) do not expressly tie the end of
one time period to the beginning of the next time period.
This will be important in discussing the anticipation
rejection.
The fifth interpretation involves the following
limitation in claim 6: "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." As interpreted in the third interpretation
above, this time period is intended to include two exciting
time intervals before the termination of the enable signal and
a non-exciting time interval after the termination of the
