Abstract: A log analysis system includes a first processor unit, a second processor unit, a third processor unit, and a fourth processor unit. The first processor unit normalizes the detection log acquired by an acquirer, allocating the detection log into predefined monitoring target units, and outputs the monitoring target units. The second processor unit appends common information based on a predefined rule to each of the monitoring target units of the detection log output from the first processor unit, arranges the monitoring target units into information granularities based on the content of the detection log and common information, and outputs the monitoring target units as analysis unit information. The third processor unit gathers the analysis unit information output from the second processor unit and setting detection target event candidates based on a predefined rule, and outputs the detection target event candidates and the determination results.

Abstract: A conductive paste applying mechanism 14 of an embodiment of the present invention has: a swing unit 140 configured to hold a solar cell 1 so that a surface of the solar cell 1 is positioned on a holding surface; and an applying unit 142 configured to apply a conductive paste on first and second faces of the solar cell 1. In a period since the conductive paste is applied on the first face until the conductive paste is applied on the second face, the swing unit 140 swings around the swing axis as a center while holding the solar cell 1. There is an offset in the perpendicular direction between the swing axis and the holding surface.

Abstract: A conventional appliance monitoring apparatus handles only the amount of gas used and security information for the case of a gas cutoff and can not address social needs for a desire to obtain information about influence (e.g., an amount of CO2 emission) of use of the gas combustion appliance on a terrestrial environment. A CO2 emission calculation unit 4 calculates an amount of CO2 emission based on a gas appliance used by a client output from an appliance determination unit 2, a gas flow signal thereof, and CO2 emission data pertaining to the gas appliance stored in a CO2 emission data storage unit 3. Thus, it is possible to determine the amount of CO2 emission produced by using the gas appliance by the client.
