Even when setting a complicated spam judging condition, it is possible to reliably determine a necessary electronic mail in reality (i.e a mail that is not a spam mail), without deleting a necessary electronic mail or the like. Based on the assumption that an electronic mail from a mail address to which transmission was performed in the past has a high possibility of not being a spam mail, a transmission destination mail address of an electronic mail transmitted to outside the organization is recorded as a permitted mail address (Step 506-Step 510), and when a transmission source address of an electronic mail destined to inside the organization matches a mail address registered in a permitted mail address database (Step 511: Yes), processing is performed to unconditionally receive this electronic mail (Step 504).

The present invention provides an abnormity determining method for a battery pack and the battery pack thereof. Whether the secondary battery is abnormal can be reliably determined in the battery which is obtained through connecting a plurality of secondary batteries. In charging of the secondary batteries, after stopping EFT which is inserted into a charging/discharging path for charging/discharging for 250ms (between time T1 and time T2 and between time T3 and time T4) is repeated every 10 minutes, the secondary battery is conducted. Based on differences (deltaV(1) and deltaV(2)) of the secondary batteries before conduction and after conduction and charging current detected before conduction, the internal resistance of the secondary battery is calculated every 10 minutes and is stored in a RAM. Hereon, on condition that the difference between a newly calculated internal resistance and the internal resistance which is formerly calculated and stored in the RAM is larger than a first threshold value, whether the secondary battery is abnormal is determined through comparing a difference between the newly calculated FCC (full capacitance) and the FCC that is formerly calculated and stored in the RAM with a second threshold.

In a diesel engine provided with a diesel particulate filter 81 and an exhaust throttle valve 9, noise is decreased that is produced when the exhaust throttle valve is returned back to the fully opened state after a diesel particulate filter 81 has been regenerated by oxidizing and removing the particulate matter deposited thereon. The exhaust system of the diesel engine is equipped with the diesel particulate filter 81 and a catalyst 82 on the upstream thereof, and is further equipped with the exhaust throttle valve 9 on the downstream. The diesel particulate filter 81 is regenerated by operating the diesel engine in a state where the exhaust throttle valve 9 is opened to a small degree.
