transistor Q6 or Q9. It cannot be said that the conductance path
of transistor Q5 is coupled in parallel with the conductance path
of either one of current mirror transistor Q6 or Q9.
Note that two elements being connected in parallel means the
input terminals share a common node and the output terminals
share a common node. That is consistent with the appellant's
specification which shows transistors 34 and 36 as collectively
constituting a hysteresis stage 12. There is a common node
between the drain of current mirror transistor 28 and the current
input to hysteresis stage 12, and a common node between the
source of current mirror transistor 28 and output of hysteresis
stage 12.
Further with respect to claim 8, which recites that the
hysteresis stage includes a "hysteresis mirror transistor having
its conductance path in series with the conductance path of a
switching transistor," the examiner incorrectly found (Paper No.
9, page 3) Sakai's transistor Q5 as the switching transistor and
transistor Q10 as the hysteresis mirror transistor. As can be
readily seen in Sakai's Figure 5, the conductance path of
transistor Q10 is not in series connection with the conductance
path of transistor Q5. Rather, the collector of transistor Q10
is connected to the base of transistor Q5.
