A preprocessing unit identifies an original text input from an input unit as one of a plurality of types of basic element functions defined in advance as basic element functions that construct a description format of a claim, and outputs the original text in basic element functions. A server-side agent running on a server data processing system monitors for a selected event for processing by the server-side agent. It is proposed that access to a non-occupied time slot by a plurality of transmission units is controlled in that one of said transmission units wins the corresponding time slot of the next cycle based on comparing priority values. Thus, by the wave washer spring pushing against the center of the computer chip, secure contact pressure is provided between the heat sink and the computer chip, while minimizing the amount of pressure between the computer chip’s pins and the chip socket. The stent may have a radially compressed configuration and a radially expanded configuration, in which the first section has a first shortening ratio, and the second section has a second shortening ratio less than the first shortening ratio.
