corner a projection comprising an upstanding pole 4 and
protrusion 3, and the upper half member includes corresponding
pole-receiving projections or portions 9 each consisting of a
pole-receiving hole 6, a deformation hole 7 and a through hole 8
(see Figure 2). When the half members are mated to one another,
the upstanding protrusions 3 extend through the holes 8 into the
deformation holes 7. An acoustic horn is inserted into the
deformation holes 7 to apply pressure to the tips of the
protrusions 3 to deform them into rounded heads 3' which hold the
half members together (see Figure 3).
In the examiner’s view, it would have been obvious to one of
ordinary skill in the art at the time the invention was made to
provide the casing of Hitachi Maxell, as modified in view of
Kato, with (1) welding projections of the sort disclosed by Kita
to eliminate the problem of excess melted resin during the
welding process (see pages 6 and 7 in the main answer) and (2) a
recess or indent as taught by Young to allow a welding horn to
effectively weld the casing members together (see page 7 in the
main answer).
As described above, the purpose of Young’s recess or indent
7 is to allow a welding horn to apply pressure to protrusions 3
to deform them into rounded heads 3'. Kita’s welding projections
differ markedly from the corresponding projections disclosed by
Young, and have no apparent need for a recess of the sort
