Appeal No. 2001-2416
Application No. 08/843,978
The examiner points to column 8, lines 24-64, column 9, line 66 through column 10, line
13, for support for a means for calculating the spot position correction signal as a linear
function in time that has predetermined position indication values at instants
corresponding to a first and second instant. The examiner further considers that the
claimed feature of the spot position indication signal being independent of a width of the
scan or the number of scanning lines is met by Kii, at column 9, line 66 through column
10, line 13, where Kii teaches that addresses (i.e., the spot position indication signal)
are called out for reading the store adjustment and arranged in a 9 x9 data map format
which is scanned in both the x and y directions.
The examiner recognizes that Kii does not teach or suggest the generation of
position information related to the deflection current, the measurement of first and
second instances as instants at which the position information has first and second
values, respectively, or the calculation of the spot position indication signal wherein
such signal has predetermined position indication values at instants in a later scan
period corresponding to the first and the second instants.
The examiner turns to Tanaka for a teaching of an improved interpolation
technique which determines a correction value of the designated point by use of a
linear relation corresponding to reference points, at column 3, lines 34-66, and to Hintze
5
