If one were to identify flange 52 of Kikuchi as the

the first and second wall portions in Kikuchi, as the majority
does, then one might argue, as the majority apparently does,
that now the second wall portions 55 (as well as the first wall
portions 58) in the modified version of Kikuchi are formed with a
stopper ledge while the first wall portions 58 are formed with
claws. The problem with this approach is that if Kikuchi is to
be modified by employing the spring-loaded mechanism of Azuma,
then the stopper ledge would be element 9 because this is the
portion on which the bottom surface of the disk will lie. If
flange 52 of Kikuchi is to be the stopper ledge, as identified by
the majority, then the bottom of the disk must lie thereon and
element 9 of the spring-loaded mechanism of Azuma may not be
employed. But, if element 9 is not to be employed, one is left
with the situation that Kikuchi is to be modified but only by
