          tion                                                                        
          of claims 5, 15 through 20, 33 through 42 and 45 through 47.                
          Claims 7, 8 and 29 have been allowed.  Claims 1 through 4, 6,               
          9 through 14, 21 through 28, 30 through 32, 43 and 44 have                  
          been cancelled.                                                             
                    Appellants' invention relates to an optical semi-                 
          conductor device capable of producing light with a stable                   
          wavelength.  On page 12 of the specification, Appellants                    
          disclose that Figure 7 shows a principle and fundamental                    
          configuration of an optical device according to the first                   
          aspect of the present invention.  On page 13 of the specifica-              
          tion, Appellants disclose that Figure 7 shows a semiconductor               
          laser diode 1 and an optical modulator 2.  Figure 7 further                 
          shows a resistor means 5 which   is connected in between the                
          current source 4 and the input of semiconductor laser diode 1.              

                                          2
