****************************************************** PR # 41179 We propose systematic observations of a homogeneously-selected complete sample of far-infrared luminous objects. We selected nine objects with L$_{\rm FIR } > 10^{12.5}$ L$_{\odot}$ from Strauss et al.'s 2-Jy All Sky Survey catalog, as FINAL targets to be observed. This luminosity range is a natural extention of the FIR luminocities of luminous Seyfert galaxies to quasars. Three of the nine objects have been already observed by ASCA (Mkn231, 3C273, and 03185+4227 as an AO-3 target) and other THREE objects are selected for the primary targets in this AO-4 observations. The results constrains (1) abundance and properties of "type-2 (obscured) quasars" and (2) frequency of strong AGN activities among the gas-rich, FIR luminous objectss with intense starburst. } } ******************************************************
