          Appeal No. 1997-3241                                                        
          Application 08/442,726                                                      


               First, we consider the rejection of claims 15, 16 and 17               
          under 35 U.S.C.  102 as being anticipated by Miu.                          
          Anticipation is established only when a single prior art                    
          reference discloses, expressly or under the principles of                   
          inherency, each and every element of a claimed invention as                 
          well as disclosing structure which is capable of performing                 
          the recited functional limitations.  RCA Corp. v. Applied                   
          Digital Data Sys. Inc., 730 F.2d 1440, 1444, 221 USPQ 385, 388              
          (Fed. Cir. 1984), cert. dismissed, 468 U.S. 1228 (1984); W. L.              
          Gore & Assoc., Inc. v. Garlock Inc., 721 F.2d 1540, 1554, 220               
          USPQ 303, 313 (Fed. Cir. 1983), cert. denied, 469 U.S. 851                  
          (1984).                                                                     
               The Examiner asserts on page 3 of the answer that “[t]he               
          claimed ‘ripple counter’ corresponds to the initialize counter              
          10-50, MUX 10-52, MUX 10-54, replacement level generator 10-6               
          and cache control circuits 10-4 shown in figures 1-3."                      
          Further, the Examiner asserts that the comparing is performed               
          by comparators 10-602, 10-622.  On page 4 of the answer, the                
          Examiner contends that Miu teaches in column 4, lines 39-53,                



                                          4
