  • Patent number: 11380103
    Abstract: A surveillance performance (information expressing uncertainty of information relating to a potential risk area in a region that requires monitoring) and a tracking performance (information expressing the product of an importance level of a potential risk area and a coverage ratio (an overlap rate between potential risk areas and moving bodies)) are mutually analyzed, and plural moving bodies are allotted to either surveillance or tracking. Potential risk areas that require monitoring are determined such that the surveillance performance and the tracking performance respectively satisfy predetermined levels. The plural moving bodies are allocated to potential risk areas determined to be potential risk areas that require monitoring (simultaneous optimization). The respective moving bodies subject to simultaneous optimization start moving toward their allocated potential risk areas to monitor the potential risk areas.

  • Publication number: 20220140356
    Abstract: An object provides a power generation apparatus performing the purification of an Al alloy melt using scrap as raw material. A power generation apparatus includes: a container body with aluminum alloy melt and molten salt in a liquid junction with the aluminum alloy melt; an anode which is in contact with the aluminum alloy melt; and a cathode which is in contact with the molten salt. DC power is obtained from between the anode and the cathode by an anode reaction on the aluminum alloy melt side and a cathode reaction on the molten salt side. When the aluminum alloy melt and the molten salt are separated by a separator allowing ionic conduction between the aluminum alloy melt and molten salt, the power generation efficiency is enhanced. The amount of a reactant in the Al alloy melt is monitored by measuring the electrical quantity associated with the power generation.

  • Publication number: 20220111464
    Abstract: A novel spot welding method for steel sheets and an aluminum alloy sheet, includes stacked sheet materials from a pair of opposing electrodes to join the sheet materials by resistance heating. The pair of opposing electrodes are in pressure contact with both outer surfaces of the sheet sets. The sheet sets include at least a first and second steel sheet, and an aluminum alloy sheet stacked in this order. A first energization step forms a molten pool between facing surfaces of the first and second steel sheets without melting the aluminum alloy sheet. A second energization step causes a melting reaction between facing surfaces of the second steel sheet and the aluminum alloy sheet. The first and second steel sheets are joined via a first nugget. The second steel sheet and the aluminum alloy sheet are joined via a second nugget including an intermetallic compound generated by the melting reaction.

The nugget has a diameter that is ?4?t (t: thickness of sheet material) and a flattening level of 3.5 to 8, which is a ratio of diameter to thickness. Both outer surface parts of the sheet materials are free from protrusions formed due to bulging of molten metal. Even when the electrodes are made of a copper alloy, the increased amount of Cu in the outer surface parts is 0.2 mass % or less with respect to the component composition before spot welding.
