              BARRY, Administrative Patent Judge.

                     A patent examiner rejected claims 32 and 33.  The appellant appeals therefrom                       
              under 35 U.S.C. § 134(a).  We reverse.

                     The invention at issue on appeal supplies an internal power-source potential to a                   
              predetermined load.  Figure 98 of the appellant's specification shows a conventional                       
              circuit for supplying an internal power-source potential in a semiconductor device.                        
              Specifically, an external power-source potential (VCE) is applied as an internal power-                    
              source potential (VCI) to a load (11) via a driving transistor (Q1).  A comparator (1)
