A fuseanti-fuse structure is provided in which programming of the anti-fuse is caused by an electromigation induced hillock that is formed adjacent to the fuse element. The generated print data is transmitted to a printing apparatus. The vector memory stores a vector memory array. Then, the channel processor permits an access of a permission access type corresponding to the judged network relative logical distance with respect to a target upper grade apparatus. The CPU collates the feature information extracted thereby with that of the feature information stored in the memory which corresponds to the position detected thereby. More particularly, the present invention directed to a real-time monitoring apparatus for biochemical reaction, which comprises parabolic mirror andor an optical waveguide tube for effective irradiation of light over the whole plate with uniform intensity.
