Abstract: An information processing system includes a first information processing device, a second information processing device, and a relay device connected to the first/second information processing devices over different buses. The first information processing device updates firmware of the power control microcomputer and transmit, to the power control microcomputer, a reactivation instruction signal after the firmware is updated. The power control microcomputer: executes reactivation of the power control microcomputer when the reactivation instruction signal is received from the first information processing device; determines whether or not the executed reactivation is reactivation that is executed immediately after the firmware update; and supplies the operation voltage to the first information processing device when the power control microcomputer determines that the executed reactivation is reactivation immediately after the firmware update.

Abstract: An information processing system includes: a plurality of information processing devices; and a relay device that includes a plurality of buses to which the information processing devices are connected. The relay device requests a main information processing device among the information processing devices to execute a shutdown once the relay device receives an operation of forcibly shutting down the information processing system, the shutdown being requested on a condition that a power state of the main information processing device is activated. The main information processing device shuts down the main information processing device once the main information processing device receives the request for the shutdown.

Abstract: A seal structure for sealing a gap between a first member and a second member of an aircraft includes: a plate spring-shaped first elastic seal; and a second elastic seal. When the first member and the second member are stationary with respect to each other, the first elastic seal elastically deforms between the first member and the second member to seal the gap, whereas the second elastic seal does not seal the gap. When the first member and the second member move closer to each other and the first elastic seal is elastically deformed, the second elastic seal elastically deforms between the first member and the second member to seal the gap.

A damper is a hydraulic head difference type damper for supplying ink supplied from an ink tank of an inkjet printer by a hydraulic head difference, into a head. The damper has a supply chamber for temporarily storing ink, an ink chamber connected to the supply chamber through a connection passage and configured to supply the ink into the head, and an on-off valve. The on-off valve opens the connection passage if the ink contained in the ink chamber decreases, and blocks the connection passage if the ink contained in the ink chamber increases. A guide port for guiding the ink contained in the ink chamber to a circulation tube for circulating the ink between the ink chamber and the ink tank is formed in the ink chamber.
