 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, Suzaku wide-band spectra of temporary dips of Hercules X-1 were analyzed. From the orbital phase, they are classified as anomalous dips. We successfully obtained the spectra from 0.3 to 60 keV with good statistics, and investigated the physical state of the absorbing materials. The HXD-PIN spectra in the 20-60 keV band allows us to estimate the total hydrogen absorption column as approximately 20 x 10(exp 22) cm(sup -2), in the deepest case, by attributing the dip mainly to the Thomson scattering. In the XIS soft X-ray spectra of the dips, signature of O VII edge was observed, suggesting ionized nature of the absorbing materials, with another evidence of partial covering. Time variability of the dips are typically explained by pile up of approximately 200 s  dips. Based on these observational results, we propose a model that the dips are made by a sum of two types of geometrically thin absorbers, with ionization parameter of approximately 0.5 erg cm(sup -1) and approximately 15 erg cm(exp -1) located around the edge of the accretion disk., 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: AA0064574096, レポート番号: JAXA-SP-09-008E},
