Appeal No. 1998-0883
Application 08/498,570
not written in means-plus-function format under 35 U.S.C.
§ 112, sixth paragraph. However, it contains similar
language to claim 1 and the issues are the same. The claims
will stand or fall together with representative claim 1.
Clock signals
The limitation of "means for generating clock signals
having phases that deviate from one another sequentially by
1/8 of a period of a dot reference clock signal" would not
be an issue except for the Examiner's statement of the
rejection.
Usami discloses that the delay line 206 in Figure 15
provides eight types of delay patterns, which are 1/8 of the
reference unit of the pulse width modulation (or 1/4 pixel
since a reference unit is two pixels) (col. 14, lines 60).
That is, the patterns have delays of 0/4 to 7/4 pixel
(col. 14, lines 60-63). Appellant admits that Usami
discloses generating eight types of delay patterns and
selecting any one of the eight delay patterns for Y, M, C,
and Bk color signals (Br5).
