Appeal No. 1997-0322
Application 08/014,574
The examiner relies on the following references:
Helldörfer et al. (Helldörfer) 4,989,333 Feb. 05,
1991
Ueno et al. (Ueno) 5,170,354 Dec. 08,
1992
Kendall 5,253,424 Oct. 19,
1993
(filed Dec. 27,
1991)
Claims 15, 16, 19, 20, 22 and 23 stand rejected under
35 U.S.C. § 103. As evidence of obviousness the examiner
offers Helldörfer alone with respect to claims 15, 16 and 23,
Helldörfer in view of Ueno with respect to claims 19 and 20,
and Helldörfer in view of Kendall with respect to claim 22.
Rather than repeat the arguments of appellants or the
examiner, we make reference to the briefs and the answers for
the respective details thereof.
OPINION
We have carefully considered the subject matter on
appeal, the rejections advanced by the examiner and the
evidence of obviousness relied upon by the examiner as support
