          Application 07/914,654                                                      



          Steck                         4,722,752           Feb.  2, 1988             
                                             (Filed June 16, 1986)                    
          Kremer                        4,828,751           May   9, 1989             
                                             (Filed Aug. 28, 1987)                    
          Kurokawa et al (Kurokawa)     5,105,556    Apr. 21, 1992                    
                                             (Filed Aug. 9, 1988)                     

               Claims 17 through 23, 25 and 26 stand rejected under 35                
          U.S.C. § 103 as unpatentable over the combined disclosures of               
          Steck, Kremer and Kurokawa.                                                 
               We have carefully reviewed the entire record, including                
          each of the arguments and comments advanced by appellants and               
          the examiner in support of their respective positions.  This                
          review leads us to conclude that only the examiner's rejection              
          of process claims 17 through 20, 25 and 26 is well-founded.                 
          Accordingly, we shall affirm the rejection of process claims                
          17 through 20, 25 and 26, but reverse the rejection of                      
          apparatus claims 21 through 23.  Our reasons for these                      
          determinations follow.                                                      
               At the outset, we note appellants' argument that "each of              
          the claims [is] separately patentable over the prior art.."                 
          See Brief, page 5.  To the extent appellants have argued the                
          limitations of each claim separately consistent with 37 CFR                 

                                          4
