Abstract: A method of judging entries for a contest is provided for judging a large number of the entries easily and fairly. The method comprises the steps of registering each entry of a contestant; selecting a predetermined number of entries from the entries of the contestants and requesting another contestant to judge the predetermined number of the entries; registering the entry of the another contestant; and ranking the entries judged by the contestants.

Abstract: The invention provides for sharing a socket between a new-standard IC card provided with side electrodes on the sides thereof, to thereby allow the number of connections to be increased, and a current-standard IC card, and to prevent the side electrodes and the mating side electrodes of a socket from being rubbed against each other by a simple structure without any need for specific operation when an IC card is inserted or removed.
