The engine system with a reformer includes a controller which, when the hydrogen generated by the reformer is supplied to the engine, determines a target heat generation beginning timing in accordance with a load applied to an engine, an engine speed, and an air excess ratio of an air-fuel mixture, and which controls an ignition timing of the engine so that a difference between a current heat generation beginning timing and the target heat generation beginning timing of the engine is within a predetermined range.

Abstract: In a resin granulating apparatus of the present invention, a bracket extending in the outward radial direction over an outer peripheral surface of a sleeve is provided for the sleeve for rotatably supporting a cutter shaft of a cutter for shearing a material extruded from a die. Stopper means cooperating with the bracket to regulate movement of the sleeve toward the die and moving a regulation position in the axial direction is provided on the radially outer side over an outer diameter of the sleeve. With such a configuration, installation space is compactified so as to additionally provide the stopper means in the existing facilities, and a position of the cutter relative to a die surface is precisely adjusted so as to stably produce a pellet of a best shape.

Abstract: The invention provides a hydrogen sensing device capable of preventing sensor sensitivity decreases. A hydrogen sensor 150 detects the hydrogen in an exhaust pipe and is installed in a divergent pipe DP. Flowing through the exhaust pipe is off-gas discharged from the fuel cell of a fuel cell vehicle. In order to decompose the siloxanes contained in the gas, a siloxane decomposing material 130 is placed upstream of the hydrogen sensor 150 inside the divergent pipe DP. Also, an SiO2 capturing material 140 is placed between the siloxane decomposing material 130 and the hydrogen sensor 150, so that the SiO2 capturing material can capture the SiO2 resulting from the decomposition of siloxanes by the siloxane decomposing material 130.

Abstract: A recombination apparatus is provided to an off-gas system of a boiling water nuclear plant. An off-gas system pipe connected to a condenser is connected to the recombination apparatus. A catalyst layer filled with a catalyst for recombining hydrogen and oxygen is disposed in the recombination apparatus. The recombination catalyst has a percentage of the number of Pt particles whose diameters are in a range from more than 1 nm to not more than 3 nm to the numbers of Pt particles whose diameters are in a range from more than 0 nm to not more than 20 nm, falling within a range from 20 to 100%. The condenser discharges gas containing an organosilicon compound (ex. D5), hydrogen, and oxygen, which is introduced to the recombination apparatus. Use of the above recombination catalyst can improve the performance of recombining hydrogen and oxygen more than conventional catalysts and the initial performance of the catalyst can be maintained for a longer period of time.

Abstract: Fins are arranged on the rotating side of an X-ray computed tomography apparatus. The fins are rotated to generate airflow as the rotating side is rotated. This airflow serves to discharge wear debris to the outside of the X-ray CT apparatus, thereby preventing the wear debris from scattering toward an X-ray tube and support bearing. In consequence, in the X-ray CT apparatus provided with a slip ring, the wear debris produced in a contact space between the slip ring and a brush can be prevented from being scattered in the apparatus.
