Abstract: A coating method for a cationic electrodeposition coating material includes steps for immersing a metal object to be coated in a first solution bath, a second solution bath and a third solution bath, and wherein: at least one step among the three steps is cationic electrodeposition coating that is accompanied by application of a current; a coating film which is formed through the three steps contains at least a base resin component (A), a reaction component (B) and a catalyst (C); and the first solution bath, the second solution bath and the third solution bath contain one or a combination of two of the base resin component (A), the reaction component (B) and the catalyst (C).

Abstract: A coating method for a cationic electrodeposition coating material includes: a step of immersing a metallic article to be coated in a first solution bath, a step of immersing the article in a second solution bath and a step of immersing the article in a third solution bath; and at least one of the three steps includes a cationic electrodeposition coating in which a current is applied. A coating film formed through the three steps contains at least: a base resin component (A), a reaction component (B) and a catalyst (C). The first solution bath, the second solution bath and the third solution bath contain the base resin component (A), the reaction component (B) and the catalyst (C) in a combination of one or two of the components.

Abstract: A storage controller connected to a computer makes an IO request and has drive boxes connected to the storage controller. The storage controller configures a RAID group and the drive boxes store DB information including information for accessing the drive boxes connected to the storage controller and RAID group information of the RAID group configured by the storage controller. A first processor of a first drive box reads, if new data for updating old data stored in a first drive of the first drive box is received from the storage controller, the old data from the first drive and generates intermediate parity from the old data and the new data, transfers the intermediate parity to a second drive box storing old parity corresponding to the old data on the basis of the DB information and the RAID group information, and stores the new data in the first drive.
