The following three prior art references are relied upon
by the examiner as evidence of obviousness:

Taubitz et al (Taubitz) 4,990,564 Feb. 5, 1991
Koch et al (Koch) 5,071,924 Dec. 10, 1991
Claims 20 and 34-38 stand rejected under 35 U.S.C. § 103
for obviousness in view of Saito in combination with Taubitz
and Koch.2
We have carefully considered the entire record in light

rejected under 35 U.S.C. § 112, second paragraph, in the final

maintained in the examiner's Answer, we presume that the 35
U.S.C. § 112 rejection has been withdrawn.
