Abstract: An exhaust purification unit includes: a connecting pipe transmitting exhaust gas to a selective reduction catalyst (SCR); a urea water injection valve arranged to face an exhaust upstream end of the connecting pipe and injecting urea water into the connecting pipe; a mixer chamber forming a flow path along which exhaust gas flows from an exhaust downstream end of a front stage casing and turns back to the exhaust upstream end of the connecting pipe; and a flow adjustment member provided in the mixer chamber, being a member having a truncated-cone shape which extends from a vicinity of the injection opening of the urea water injection valve towards the connecting pipe with a diameter thereof gradually increasing, in which a plurality of small holes is formed, and in which a claw that guides the exhaust gas towards the exhaust downstream-side is provided for each of the plurality of small holes.

Abstract: A computer achieves an increase in throughput by controlling a connection state between each port of an I/O controller and an I/O switch, thereby improving throughput imbalance between the ports of the I/O controller. The computer is provided with: an I/O switch; an I/O device connected to the I/O switch; a management controller; and an I/O controller including a plurality of ports. The management controller detects a connection state with the I/O switch, and acquires the number of virtual switches associated with the detected connection state with the I/O switch by referring to configuration management information for managing the connection state with the I/O switch in association with the number of the virtual switches. The management controller sets the acquired number of the virtual switches for each I/O switch that is connected. Each port of the I/O controller connects with the I/O device via the virtual switches that are set.
