          Application 08/200,044                                                      

          being connected in parallel with said first and second cooling              
          apparatus, respectively; and                                                
               a microcontroller connected to said first and second                   
          variable resistances and controlling said first and second                  
          variable resistances.                                                       
               12.  A laser module comprising:                                        
               first and second lasers, said lasers being connected in                
          series;                                                                     
               first and second variable resistances, said first and                  
          second variable resistances being connected in series and                   
          being connected in parallel with said first and second lasers,              
          respectively; and                                                           
               a microcontroller connected to said first and second                   
          variable resistances and controlling said first and second                  
          variable resistances.                                                       

                                       Opinion                                        
               We reverse.                                                            
               Our opinion is based only on the positions as expressed                
          by the examiner.  We do not undertake to perform examination                
          de novo based on prior art, even those already of record.  Our              
          reversal of the rejections on appeal should not be construed                
          as a pronouncement that the claimed invention is patentable                 
          over prior art including the same reference relied on by the                
          examiner.                                                                   
          The rejection under 35 U.S.C.                                               
          § 112, first and second paragraphs
