dc.descriptionAs a progenitor of NHE (Non High Energy) GRBs, we propose a (C+O) star and a neutron star (black hole) close binary system. Since the (C+O) star is tidally locked, a new born pulsar should be a milli second pulsar (MSP). Dynamo will generate a superstrong magnetic field(SSM). The beam of the energy from the super strongly magnetized milli second pulsar can punch a hole in the supernova ejecta . Then the beam of gamma rays flows out of the ejecta. If we observe this beam from the lateral direction, it will be NHE-GRB. In this model the pulsar with the spin period about 1sec should exist in SN1998bw so that the searches for this pulsar in all the wave length are urgent. SSM-MSPs can accelerate protons up to Ultra High Energy. If a few percent of the beam energy of SSM-MSP in NHE-GRB event is in the form of UHECRs, the flux of the observed UHECRs can be explained. Then along the direction of each UHECR, a supernova remnant should be found. It is suggested that NHE-GRB is the progenitor of the soft gamma ray repeater which has also the superstrong magnetic field and is in the supernova remnant.
