          Appeal No. 1999-2280                                                        
          Application No. 08/686,567                                                  

          inapposite reasoning in any justification for the anticipation              
          rejection.  Thus, the 35 U.S.C. § 102(b) rejection of claims 1,             
          2, 4, 6 through 14, 16, 18 through 24, 26 and 28 through 30 is              
          reversed because we agree with appellants’ argument that silicon            
          dioxide is not silicon.                                                     
               Based upon the same reasoning, the 35 U.S.C. § 103(a)                  
          rejection of claims 3, 15, 25 and 31 is reversed.  The 35 U.S.C.            
          § 103(a) rejection of claims 5, 17 and 27 is reversed because the           
          teachings of Petersen do not cure the noted shortcoming in the              
          teachings of Kubo.
