view of combinations of Russell and the following references:
Inoue for claim 37, Hashimoto for claims 24 and 26, and Rees for
claim 33. All pending claims ultimately depend from claim 23.
DISCUSSION
The examiner found that Russell's adders 116 (Figs. 2 & 4)
teach claim 23's "signal combining means coupled to at least two
of the error signal generating circuits for combining the error
signals produced thereby so as to derive a control signal." We
disagree. Russell's adders 116 combine detection signals, not
error signals as claimed. The device of claim 23 processes
detection signals to produce error signals and then combines the
error signals. Thus, Russell does not teach "signal combining
means coupled to at least two of the error signal generating
circuits for combining the error signals produced thereby so as
to derive a control signal."
Since the cited prior art does not teach or suggest a
limitation in claim 23, we reverse the rejection of claim 23.
Inoue, Hashimoto, and Rees do not teach or suggest the missing
limitation so we reverse the rejection of claims 24-26, 33,
and 37 as well.
