Appeal No. 97-1250
Application 08/347,087
and the examiner with regard to the merits of these rejections.
Udagawa discloses “a steel laminate gasket for an internal
combustion engine to securely seal around cylinder holes” (page
2, column 1, lines 4 through 7). Each of the gasket embodiments
described by Udagawa includes holes Hc corresponding to the
cylinder holes of the engine. The Figure 6 embodiment relied
upon by the examiner is described as follows:
FIG. 6 shows a fourth embodiment D of a steel
laminate gasket of the invention. The gasket D
comprises an upper plate D10 with a curved portion
D10a, a flange D10b and a bead D10c, a middle plate D11
with a bead (not shown) around the water hole Hw, and a
lower plate D12, similar to the gasket B.
However, the lower plate D12 does not have a core,
and instead, a core D10d is integrally formed with the
flange D10b. Namely, the core D10b [sic, D10d] is
formed by bending the same to be located on the flange
D10c [sic, D10b]. An end D12a of the lower plate D12
is located on the core D10d. The gasket D operates as
in the gasket B [page 4, column 6, lines 6 through 19].
Claims 1 and 12, the two independent claims on appeal,
recite a metal laminate type cylinder head gasket comprising,
inter alia, a first metal plate including a first hole
corresponding to a cylinder bore, a heat preventing portion for
defining the first hole and being formed at an inner end portion
of the first plate, and a main sealing portion situated around
the heat preventing portion and being formed of at least three
