the bottom of page 26. The context of this latter portion of
the specification has been established for proper
understanding of the earlier portions in the specification in
the context of the discussion of Figures 9 and 10. The brief
description of Figure 17 at the bottom of page 4 of the
specification as filed describes in
brief detail the block diaphragm in this figure as relating to
circuitry of a camera capable of varying full aperture value.
The discussion noted in the pages which follow through the end
of page 26 clearly establish that the claimed aperture
diameter is, in fact, held constant and that the so-called
aperture value varies as the focal length is varied. The
relationship of these terms is defined at the bottom of page
24 where the aperture value is said to be calculated from the
focal length divided by the aperture diameter. It goes on to
state that “when the shutter aperture remains unchanged during
variation in the focal length, [the aperture value] will be
varied systematically.” In context the full open aperture
