Appeal No. 96-1895
Application 08/011,682
The switching circuit 32 is turned OFF at the time of the
seek operation (col. 8, lines 43-46) and at the time of the
transient control operation (col. 9, lines 19-20) and ON
upon a shift from the transient control operation to the
track following control operation (col. 6, line 67, to
col. 7, line 3). The switching circuit 32 effectively
performs the function of switching PCC 31 ON and OFF.
Therefore, Kanda teaches a position control system, as
recited in the independent claims, where "switch means
selectively turns said low pass filter off during a seek
operation of said controlled device [or magnetic head in the
case of claim 9] and on during a settling operation of said
controlled device [or magnetic head in the case of
claim 9]."
Appellant argues that "[a]s described in Amendment B
[sic, C], Kanda et al. likewise fail to disclose that the
low pass filter (i.e., the PCC 31 of Kanda et al.) is turned
ON by a switching operation when a seek operation proceeds
to a track following operation" (Br15). Again, although
arguments belong in the brief, we have considered the
arguments in Amendment C (Paper No. 14). Appellant argues
