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

          afforded by the written description contained in the                         
          applicant's specification").  It is also axiomatic that                      
          limitations from examples given in the specification cannot be               
          read into the claims.  Constant v. Advanced Micro-Devices,                   
          Inc., 848 F.2d 1560, 1571, 7 USPQ2d 1057, 1064 (Fed. Cir.                    
          1988); In re Priest, 582 F.2d 33, 37, 199 USPQ 11, 15 (CCPA                  
          1978); and In re Prater, 415 F.2d 1393, 1404-05, 162 USPQ 541,               
          550-51 (CCPA 1969).  Furthermore, the fact that each of                      
          appellants' disclosed embodiments of flash fire control                      
          circuit 5 employs a transistor Q3 which is directly responsive               
          to the flash terminating signal for short-circuiting the gate                
          of the IGBT to ground is not in and of itself a sufficient                   
          basis for construing the claim language as implicitly                        
          requiring a device (e.g., a transistor) for short-circuiting                 
          the IGBT gate to ground (or, more broadly, to a source of                    
          reference potential) in response to the flash terminating                    
          signal.  See Specialty Composites v. Cabot Corp., 845 F.2d                   
          981, 988, 6 USPQ2d 1601, 1605 (Fed. Cir. 1988) ("Where a                     
          specification does not require a limitation, that limitation                 
          should not be read from the specification into the claims.")
