Appeal No. 95-2413
Application 07/936,865
The magnets in an actual design should be arranged, as far as
possible, "in such a way that a center line between poles of
each magnet coincides [with] the designed curve 67 of FIG. 8
. . ." (col. 6, lines 10-11).
Figure 9 provides an idealized description of figure 8
which is said to be "easier to understand" (col. 6, line 28).
Each arc section of the curve 67 in figure 8 (e.g., arc a-b)
is represented as a shaded arced area at constant radius in
figure 9 (e.g., region 71 corresponds to the arc-shaped
segment containing arc a-b in figure 8). Suzuki discloses
that the idealized arrangement of figure 9 satisfies the
condition:
'L(r)/r = '" = constant
We disagree with appellants' interpretation of what this
means. Appellants interpret this equation to mean that L(r)
is the arc length across the width of the plasma path at a
radius r as shown in appellants' figure 14A. While
appellants' interpretation is consistent with Suzuki's
discussion of figure 4(a) (col. 3, lines 26-40), it is not
consistent with Suzuki's description of the plasma having "a
very narrow width" (col. 5, lines 60-61). In our opinion,
