Some of them have Sy.2 spectrum in optical but quasar luminosity in FIR, that is, "type 2 quasar" characteristics. Recent studies of IRAS quasars with "warm" FIR colors by ASCA have shown that some of these objects show type 2 characteristics in X-rays, while others show no sign of AGN activity. Here we propose to observe 3 warm IRAS quasars to verify the link between FIR and X-ray emission from quasars and to investigate the nature of type 2 quasars. Our studies in previous AOs have shown some hint of link between X-ray loudness and FIR colors. We will be able to verify this idea in detail with this proposal.
