Abstract: There is provided an exhaust purification apparatus for an internal combustion engine in which a catalyst capable of adsorbing and oxidizing hydrocarbon is provided in an exhaust pipe, the exhaust purification apparatus including temperature detection means for detecting a temperature of the catalyst, estimation means for accumulating a time during which the temperature of the catalyst detected by the temperature detection means is equal to or less than a predetermined temperature, and estimating an amount of hydrocarbon adsorbed on the catalyst from the accumulated time, and control means for controlling fuel ejection of the internal combustion engine in a first ejection mode in which the temperature of the catalyst is increased to a temperature where hydrocarbons adsorbed on the catalyst are oxidized, in a case in which the amount of hydrocarbons estimated by the estimation means exceeds a predetermined upper limit.

Abstract: A code generating device using biometric information, includes an input unit of biometric information, a storage unit stored with a plurality of biometric information patterns and with codes each uniquely assigned to each biometric information pattern, a code generating unit extracting one of the plurality of biometric information patterns, which corresponds to the inputted biometric information, and acquiring the code assigned to the extracted biometric information pattern, and an output unit outputting the code acquired by the code generating unit.

Abstract: In a portable-terminal usage management method, log distribution conditions are downloaded from an administrative function module to one of a plurality of portable terminals. One of a plurality of communication log storage parts is selected in accordance with the log distribution conditions whenever one of the plurality of portable terminals starts communication. A communication log related to the communication started by the one of the plurality of portable terminals is stored into the selected one of the plurality of communication log storage parts.
