   ASCA Galactic Plane Survey team including us discovered several new
   hard X-ray sources in the Plane Survey project and other Plane
   observations. AGPS267.3-27.4 and AGPS273.4-17.8 are the hardest and
   bright sources of them. We propose the deep observation of these new
   sources. We will investigate the image, spectrum, and time variability
   of them, reveal their X-ray natures, and classified them. There are
   little observational knowledges about the nature of these hard sources
   on the Galactic Plane. Our observation will reveal them first, and will
   much enlarge the significance of the survey project.
