          Appeal No. 1997-0058                                                        
          Application No. 08/300,399                                                  

          as proposed by the examiner.  Since White does not include an               
          inductance between the current sense signal and the pulse                   
          width modulator, White has no difficulty in constructing an                 
          inductance element.  Therefore, there would be no need to                   
          substitute an active filter with a feedback technique.                      
          Accordingly, we find no reason to combine Kusano with White.                
          Consequently, Kusano fails to cure the deficiencies of White                
          regarding claims 1 and 6.  Since claims 2 and 5 depend from                 
          claim 1, and therefore include the limitation of claim 1 found              
          lacking from White, we cannot sustain the rejection of claims               
          2 and 5.  Further, claims 13, 16, and 17 require that the slew              
          rate of the modified sense signal be limited to a                           
          predetermined maximum when it otherwise would exceed the                    
          maximum.  Thus, claims 13, 16, and 17 include a limitation                  
          similar to the one of claim 6 found lacking from White, and,                
          therefore, are not met by White for the same reasons as                     
          discussed above regarding claim 6.  Hence, we cannot sustain                
          the rejection of claims 13, 16, and 17.                                     
               Regarding claims 8, 11, and 12, the examiner combines                  
          Sasaki with White stating (Answer, page 6) that it would have               
          been obvious "to replace the RC slew rate limiting circuit of
