The examiner relies on the following references: Murayama et al. (Murayama) 5,478,661 Dec. 26, 1995 (filed Apr. 1, 1993) Gill et al. (Gill) 5,492,720 Feb. 20, 1996 (effective filing date Aug. 15, 1994) Claims 1-7 and 11-17 stand rejected under 35 U.S.C. § 102 as being anticipated by Murayama. Claims 8-10 stand rejected under 35 U.S.C. § 103 as being unpatentable over Murayama in view of Gill. We refer to the Final Rejection (Paper No. 7) and the Examiner's Answer (Paper No. 14) for a statement of the examiner's position and to the Brief (Paper No. 13) and the Reply Brief (Paper No. 15) for appellants’ position with respect to the claims which stand rejected.
