          Appeal No. 1997-2964                                                        
          Application No. 08/531,103                                                  

          closed position.  It is the examiner’s view that the subject                
          matter of claim 1 is rendered obvious by the combined                       
          teachings of Lamm and Ishida.                                               
               Lamm is directed to a throttle valve system for a rotary               
          piston type of internal combustion engine.  This reference                  
          discloses an intake passage (2) within which is positioned a                
          butterfly throttle valve (5).  At idle, twenty percent of the               
          intake air flows through a bypass channel (7) and eighty                    
          percent flows through openings (10 and 11) in the throttle                  
          valve itself.   While the Lamm throttle valve is at an angle                
          to the flow of air when in the position shown in Figure 1,                  
          there is no mention in the patent of the magnitude of that                  
          angle.  Thus, insofar as the subject matter of claim 1 is                   
          concerned, Lamm fails explicitly to teach the claimed angle of              
          the throttle valve.                                                         
               Ishida is concerned with the same problem as the                       
          appellant;  however, he solves it in a different fashion.  As               
          compared to the prior art throttle valve (Figure 1), Ishida’s               
          valve (Figure 2), to which the examiner apparently is                       
          referring in the rejection,  is thicker, is provided with a                 
          rounded configuration on its periphery, and specifically is                 

                                          5
