          Application No. 08/640,096                                                  


          1972                                                                        
               Claims 2 through 6 stand rejected under the first                      
          paragraph of 35 U.S.C. § 112 for lack of enablement.                        
               Claim 6 stands rejected under the second paragraph of 35               
          U.S.C. § 112 for indefiniteness.                                            
               Claims 1 through 3, 7 and 8 stand rejected under 35                    
          U.S.C.                                                                      
          § 102(b) as being anticipated by Belluche.                                  
               Claims 2, 4 through 6, 9 and 10 stand rejected under 35                
          U.S.C. § 103(a) as being unpatentable over Belluche.                        
               Reference is made to the briefs (paper numbers 9 and 11)               
          and the answers (paper numbers 10 and 12) for the respective                
          positions of the appellants and the examiner.                               
                                       OPINION                                        
               We have carefully considered the entire record before us,              
          and we will reverse all of the rejections of record.                        
               Turning first as we must to the indefiniteness rejection,              
          the examiner’s rejection is as follows (answer, page 3):                    
                    In claim 6, line 2, the recitation of “a lower                    
               threshold voltage” is indefinite.  What is the                         
               threshold voltage lower than?  On line 3, the                          
               recitation of “a terminal voltage” is indefinite.                      
               What determines a terminal voltage?                                    

                                          3
