The present invention is directed to an electroconductive thick film paste composition comprising Ag and a Pb-free bismuth-tellurium oxide both dispersed in an organic medium, wherein the paste is fireable at temperatures below 420\xb0 C. The RL includes the first or lower ferromagnetic layer MAG1, sometimes called the \u201cmedia\u201d layer, the second or upper ferromagnetic layer MAG2, sometimes called the \u201cexchange-spring\u201d layer, and the intermediate CL that provides ferromagnetic exchange coupling between MAG1 and MAG2. One end of each pawl moves between first and second engagement positions with corresponding engagement surfaces formed in the other member and a position of disengagement with the other member permitting relative rotation of the inner and outer members. Subsequently, the write access to the frame buffer is allowed when location has been rastered. Two end cover plates at the inner ring portion end cover two end faces of the hollow inner hole. Each functional module generates request packets for implementing memory access operations, each request packet having an operation field comprising eight bits of which a packet type bit denotes the type of the packet, four operation family bit denote the function to be implemented by the packet and three operation qualifier bits act to qualify the function.
