                    Application No. 08/254,654                                                                                               




                    appellants= brief.  If the meaning of  Aopto-coupler@ is not clear to the skilled artisan, it may                        
                    not be possible to determine the corresponding structure covered by the claimed means as                                 
                    required under 35 U.S.C. ' 112, sixth paragraph.  In such a case, a ' 112, second                                        
                    paragraph rejection may be warranted.  Furthermore, it appears that the power amplifier                                  
                    performs more than just an amplifying function in that the error signal is required to somehow                           
                    adjust the magnitude of the current for energizing the solenoid.
