          Appeal No. 1997-0272                                                        
          Application No. 08/277,388                                                  

          element and is performed by a diode.  More importantly,                     
          Sieverin does disclose a temperature sensitive resistor R but               
                                                                   T,                 
          it is connected to the amplifier offset terminals and not to                
          the output of the amplifier as required by claim 1.                         
          Similarly, with regard to Kostal, Figure 1 does show a Hall                 
          element 4 and amplifiers but we find no temperature sensitive               
          resistor within a temperature compensation circuit wherein the              
          temperature compensation circuit is connected to the output of              
          an amplification circuit in such a manner which prevents                    
          changes in the output signal from the Hall element from                     
          affecting a voltage potential across a temperature sensitive                
          resistor, as claimed.  The examiner identifies resistors R1,                
          R2 and R3 in Kostal as the claimed “temperature sensitive                   
          resistor” but we agree with appellant that these resistors in               
          Kostal appear to have no relation whatsoever to the output of               
          the Hall element.                                                           


               Accordingly, the rejections of claim 1 under 35 U.S.C.                 
           102(b) are reversed.                                                      
               The examiner also rejects claim 1 under 35 U.S.C.  103                
          based on APA and Mount.  However, Mount is not directed to a                

                                          7
