   Though ASCA observations of AO1 to AO4, we found many dim X-ray sources
   in globular clusters, and found evidence of the existance of CVs from
   their energy spectra obtained for the first time. Clusters previously
   observed are dense and/or large. This time, we propose observations of
   low dense but collapsed clusters. The "collapsed" means that the
   clusters were much highly dense before. The existance X-ray binaries in
   such clusters tell us the influence of the collapse of the clusters on
   the binary formation.
