************************************************************************* 71068 In ASCA Galactic Plane Survey project, we discovered several new hard X-ray sources extended about 10x10min. We propose deep observation of these objects, which are candidates for the synchrotron emission from very high energy electrons accelerated up to about 100TeV by Fermi mechanism at shock front of SNR blast wave. We will investigate the nature of these objects by the image and spectrum analysis. *************************************************************************
