An electronic message information collector collects packets transferred on a building management system network and analysis results as first electronic message information. A storage stores the first electronic message information collected by the electronic message information collector. An electronic message information collector collects packets transferred on an equipment network and analysis results as second electronic message information. A storage stores the second electronic message information collected by the electronic message information collector. An electronic message associator associates the first electronic message information stored in the storage and the second electronic message information stored in the storage. A display displays the analysis results of the association by the electronic message associator.

Network analysis device, management system, network analysis method and program

A first electronic message collector collects electronic messages travelling on a first network and stores the electronic messages in a first storage. A second electronic message collector collects electronic messages travelling on a second network and stores the electronic messages in a second storage. An electronic message associator retains a mapping table in which the correlation, or similar, between electronic messages travelling from the first network to a gateway device and electronic messages travelling from the gateway device the second network are defined. The electronic message associator references the mapping table and associates the electronic messages stored in the second storage with the electronic messages stored in the first storage. From the result of the above-mentioned association, a status analyzer determines whether or not receipt of electronic message between the first network and the second network is accomplished normally.

A capacitor structure in a semiconductor memory cell includes a lower electrode formed on a base body, a capacitor insulation film which is a ferroelectric thin film formed on the lower electrode, and an upper electrode formed on the capacitor insulation film. The lower electrode is shaped semi-spherical. The capacitor structure has an increased area of the upper electrode in contact with the ferroelectric thin film, local concentration of an electric field in the ferroelectric thin film is unlikely to occur.
