Abstract: An injector injects urea water as a liquid reducing agent; a NOx sensor detects concentration of nitrogen oxide in exhaust gas; and an air duct including an inlet side opening and outlet side opening cools at least either one of urea water in urea water hose, NOx sensor or injector with cooling air introduced from outside of the machine room. A ventilation opening at the outside of the machine room communicates with the inlet side opening of the air duct using negative pressure formed in a circumference of exhaust gas flow by an ejector arranged in an exhaust pipe passage.

Abstract: Provided is a machine body capable of preventing thermal decomposition of a liquid reducing agent in a reducing agent injector. The machine body includes an exhaust gas treatment device that reduces nitrogen oxides in exhaust gas of an engine provided within a machine room, and a reducing agent supplier that supplies the liquid reducing agent to the exhaust gas treatment device. The exhaust gas treatment device includes a reducing agent injector that injects the liquid reducing agent supplied from the reducing agent supplier, and a cooling fan that is installed in the vicinity of the reducing agent injector so as to face the reducing agent injector. The cooling fan performs cooling by blowing cooling wind of external air, which is taken in from the outside of the engine room, against the reducing agent injector and its upstream side.

Abstract: In a storage device accommodating a plurality of memory devices in a general-purpose chassis provided from both of the surface sides thereof, a cooling device is provided on the front of the memory devices. This cooling device is allowed to freely move to leave available the area in front of the memory devices, thereby enabling maintenance and replacement of the memory devices from the both surface sides of the chassis. With such a storage device of a type using a general-purpose chassis, and inserting therein a plurality of memory devices from the both surface sides thereof, even if a cooling device is located on the front of the chassis, the memory devices can be subjected to maintenance and replacement.

Abstract: A conduit repair structure in which solid objects are less likely to accumulate on a conduit bottom and that, even if solid objects accumulate on the conduit bottom, facilitates removal of the solid objects. A hollow frame-like reinforcement body laid substantially along a cross-sectional shape of a conduit (1) is constructed using a reinforcing member (2) having fixing parts (2p) arranged at predetermined intervals on the inner side of the conduit (2). Resin inner face bars (10) are attached to the inner side of the reinforcement body, and a curable filling material is placed in the space formed by the inner face bars (10) and a conduit inner wall (1a) to form a filling material layer (3). A body section (10c) of each inner face bar (10) is formed recessed in its width direction. The recessed shape of the body sections (10c) forms riblets on the bottom of the conduit, and this reduces resistance to water flowing in the conduit.

Abstract: A plurality of control packages 100 are mounted on both sides of a basic chassis 11 of a disk array device. A cable clamping mechanism 300 is disposed on the underside of the control packages 100 positioned in the space between the control packages 100 and a power unit 400. A rail portion 310 is disposed parallel to the direction in which the control packages 100 are arranged. A number of clamp cores 320 corresponding to the number of the control packages (CHA) are movably disposed on the rail portion 310. Each clamp core 320 corresponds to each of the control package 100, and clamps cables in control package units. Even when tensile force acts on the cables 200 from below, the present invention prevents this force from acting directly on a control package 100.
