          Appeal No. 95-3876                                                           
          Application 08/222,009                                                       

          be substituted for the field-effect transistor 15 disclosed in               
          Iwata's Figure 3:                                                            


















          Appellants contend, however, that the proposed combination                   
          would not supply the following claimed element:                              
                         control means for applying the                                
                    enabling voltage to a gate of the                                  
                    insulated gate bipolar transistor and                              
                    for removing the enabling voltage at                               
                    the gate in response to a flash                                    
                    terminating command.                                               
          We must, therefore, determine the scope and meaning of this                  
          limitation in the context of the claim as a whole.                           




                                        - 31 -
