****************************************************** PR # 41171 We observe one of the two peaks of the QSO cluster (z=1.0-1.2) discovered by Crampton et al. 1989. The other peak was observed with ASCA in 1995 as AO-3 target with 100 ksec exposure. Our preliminal analysis of the data suggests that observing the QSO cluster region is indeed very fruitful. 1. We may detect more QSOs than a blank sky survey in a field of view. We can not only compair Lx and Lopt but also obtain distribution of the X-ray hardness-ratio for QSOs at the same redshift. 2. We have much more chance to discover "Type-2 QSO" than in general field, since they may be in the same distribution as the ordinary optical QSO. ******************************************************
