   RS CVn binaries with white dwarf companions are in a different
   evolutionary stage compared to classical RS CVns and appear anomalous
   in X-rays. Three such binaries, FF Aqr, 39 Cet and 29 Dra, have high
   X-ray luminosities (log Lx = 31.3 - 31.5), and ROSAT PSPC spectra of
   two of them show different temperatures compared to classical RS
   CVns. A compact star in such binaries could provide conditions for
   the mass accreted from the late-type star to emit X-rays competing
   with the coronal X-ray emission from active late-type companion. ASCA
   spectra will allow us to determine their spectral components, measure
   coronal abundances, and allow comparison to be made with the existing
   spectra of higher-gravity RS CVns and other similar systems without
   compact companions.
