    PR # 31175                                                                   
     We observe QSO Cluster (z=1.0-1.2) discovered in the redshift survey        
     by Crampton et al. 1989. 1. We will detect more QSO's than a blank sk       
     y survey in a FOV.   We can compare Lx and Lopt. It may influence log       
      N - log S. 2. We may discover "Type II QSO", because they will be in       
        the same distribution as the optical QSO. QSO cluster is   the mos       
     t probable place for their existence. 3. We may detect X-ray from sup       
     er cluster. The separation   beteen QSO's in the QSO cluster is 10Mpc       
      which is a distace   between cluster of galaxies. One GIS FOV can co       
     ver the   super cluster. Deep exposure may reveal their X-ray.
