 note = {The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We present a systematic spectral analysis with Suzaku of six AGNs detected in the Swift/BAT hard X-ray (15 - 200 keV) survey. The 0.5 - 200 keV spectra of these sources can be uniformly fit with a base model consisting of heavily absorbed (logN(sub H) > 23.5 cm(sup -2)) transmitted components, scattered lights, a reflection component, and an iron-K emission line. There are two distinct groups, three "new type" AGNs (including the two sources reported by Ueda et al. 2007) with an extremely small scattered fraction (f(sub scat) < 0.5 % ) and strong reflection component (R = Omega/2pi greater than or approximately equal to 0.8, where Omega is the solid angle of the reflector), and three "classical type" ones with f(sub scat) > 0.5 % and R greater than or approximately equal to 0.8. The spectral parameters suggest that the new type has an optically thick torus for Thomson scattering (N(sub H) approximately 10(sup 25) cm(sup -2)) with a small opening angle of theta approximately 20 deg viewed in a rather face-on geometry, while the classical type has a thin torus (logN(sub H) approximately 23 - 24 cm(sup -2)) with theta > or similar to 30 deg. We infer that a significant number of new type AGNs with an edge-on view is missing in the current all-sky hard X-ray surveys., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574140, レポート番号: JAXA-SP-09-008E},
