Abstract: A power storage module includes an electrode laminate in which bipolar electrodes are laminated and a sealing body formed of a resin. The bipolar electrode includes an electrode plate, a positive electrode provided on one surface of the electrode plate, and a negative electrode provided on another surface of the electrode plate. The sealing body is provided on a side surface of the electrode laminate to surround an edge portion of the bipolar electrode. The sealing body includes a first resin portion and a second resin portion. The first resin portion is welded to the edge portion of the bipolar electrode. The second resin portion surrounds the first resin portion from an outer side along the side surface. A mold shrinkage factor of the first resin portion is lower than a mold shrinkage factor of the second resin portion.

Abstract: A processing server detects an incident of a vehicle by analyzing one of position information about the vehicle, image information about the periphery of the vehicle, and traveling data about the vehicle, which are acquired from the vehicle, and selects a new function corresponding to the detected incident. Then, the processing server gives notice of the proposal for the new function to the vehicle, as an estimated timing when a user having encountered the incident has cooled down while the user's memory about the incident is clear.

Abstract: An object of the present disclosure is to provide a method for manufacturing an aluminum alloy plastically-processed article, capable of preventing a burning crack from occurring due to processing heat generated during plasticity processing while maintaining a solution-treatment temperature of an aluminum alloy material for ensuring a mechanical strength thereof. A method for manufacturing an aluminum alloy plastically-processed article, includes a step of performing a solution treatment for an aluminum alloy material by heating and maintaining the aluminum alloy material at a solution-treatment temperature, a step of performing plasticity processing for the aluminum alloy material subjected to the solution treatment, and steps of cooling the plastically-processed aluminum alloy material at a time at which the step of the plasticity processing is completed, and aging the cooled aluminum alloy material. The method further includes pre-plasticity-processing cooling step of cooling the aluminum alloy material subjected to the solution treatment.
