          Appeal No. 95-1626                                                          
          Application 07/804,013                                                      


          C) The examiner argues that the direction in claim 2                        
          is unclear and indefinite.  We do not agree.  Claim 2 simply                
          recites that the bias field which is applied by the permanent               
          magnet should be smaller than the field strength of the MR                  
          element at maximum resistance, and that the direction of the                
          bias field is inverse to the direction of magnetization of the              
          permanent magnet.  These directions being inverse are clear as              
          shown by the sketch attached to the reply brief.  The                       
          permanent magnet causes a magnetic field to exist in the                    
          layers which is in the reverse direction of the magnetic field              
          within the magnet itself.                                                   
          D) The examiner asserts that it is unclear how a                            
          nonferromagnetic layer can be magnetoresistive as recited in                
          claim 14.  As appellants point out, however, claim 14 does not              
          make this recitation.  Claim 14 recites two different MR                    
          elements each of which is layered with ferromagnetic and                    
          nonferromagnetic layers.  Thus, it is each of the MR elements               
          which are magnetoresistive, not a nonferromagnetic layer by                 
          itself.                  E) The examiner asserts that the                   
          source of the voltage and output of claims 14, 24, 34 and 44                
          is unclear because there is no structure recited to generate                
                                          7
