          Appeal No. 1998-0992                                                         
          Application 08/706,978                                                       

               However, in the context of bandgap generators for                       
          generating a temperature stable reference voltage, the                       
          examiner is misplaced to ignore the temperature sensitivities                
          of the base-emitter voltage V  of Henry’s Q7 and to assume                   
                                       be                                              
          that it is a constant value.  From the appellants’                           
          specification it is abundantly clear that because the first                  
          component is not temperature compensated that the second term                
          is needed as an offset to produce a sum that is temperature                  
          stable.  In the context of the appellants’ invention, it is                  
          without sufficient basis for the examiner to treat the base-                 
          emitter voltage of Henry’s bipolar transistor Q7 as a                        
          constant.  Because V  is not a constant but V  is a constant,be                     o                                
          the appellants’ claimed feature is not met by the examiner’s                 
          reliance on Henry’s V  and V  of Q7.o      be                                               
               To the extent that the examiner regards the configuration               
          of elements 23 and 24 in Henry as together constituting a                    
          divider circuit, it has not been explained how that                          
          arrangement produces a value for V  that is a fixed proportion               
                                             o                                         
          of the base-emitter voltage V  of Q7.  The examiner has not                  
                                       be                                              
          indicated what that fractional proportion might be in terms of               
          an expression of the resistance values, i.e., V  equals V  ofo         be                 

                                           6
