Appeal No. 1998-2914
Application 08/510,971
The pre-processing circuit 54 includes two
differentiating circuits 71, 72 of conventional
construction, with a common input 66 connected via
signal line 66 to optical scanning device 1 (Fig.
1), while pre-processing unit 54' is connected to
scanning unit 2 via line 67. When the scanning
signal on signal line 66 goes active as a leading
edge P11, P13, P15 or P17 (Fig. 8) of a register or
reference mark is detected, a positive start pulse
is generated on the differentiating circuit's output
lead 73, and when subsequently the trailing edge of
the mark is detected, a positive end pulse is
generated on the output lead 74.
As to contention (5), the formulas for computing the various
register deviations are provided on pages 20 and 21 of the
specification and the necessary hardware for computing the
deviations and making corrections is diagrammatically
illustrated in Fig. 11. Page 25 of the specification states
that complete detail has not been shown for sake of clarity
since "such details would be readily provided by a person
having ordinary skills in the design of electronic circuits,"
and the examiner has provided no reasons whatsoever as to why
this might not be the case.
On pages 12 and 13 the answer states that:
Appellant has pointed to various pages in the
specification to support the contention that the
questioned steps as itemized above are enabling.
The conclusions made by appellant are not supported
by the submission of sufficient facts to support
those conclusions. A review of the specification
