A process for the ultrapurification of alginates is provided. The loading assembly includes at least one consumable-containing cartridge, and at least one opening in the system housing having a size and shape adapted to permit the consumable-containing cartridge to pass therethrough. The second and third states are exhibited alternately. The top surface is printed with a decorative indicia and the bottom surface is printed with an indicia of identification. The composition comprises as an active ingredient a polymer obtained by continuously polymerizing at a high temperature either a polymerizable monomer having a maleimide group and other polymerizable group or a polymerizable monomer having a succinimide group. In this manner, the space requirement for constructing the MRAM configuration is greatly reduced because the number of switching transistors required is greatly reduced.
