摘要:
The present invention is relates to a method for alternately laminating each first metal sheet and each second metal sheet in three or more layers, wherein a melting point of the second metal sheet is higher than that of the first metal sheet, and welding them together by friction stir welding.Furthermore, under a state where those three or more metal sheets are so laminated that an edge of the first metal sheet protrude outward compared to an edge of the second metal sheet, the friction stir welding is executed by pressing a welding tool against only the edge of the first metal sheet.

A compacting device of the invention includes: a die (11) having a through hole (10) extending in a vertical direction; and a container support (12) inserted into the through hole (10) vertically from below, disposed to be vertically movable in the through hole (10), and supporting a container (3) from below while being in contact with a portion of a lower surface of the container (3). The container support (12) and the through hole (10) define a housing space (S) for the container (3). The compacting device further includes: a lower punch (20a) for applying ultrasonic vibration to powder contained in the container (3); and an upper punch (20b). The container support (12) has a movement path (15) for the lower punch (20a), formed along the entire vertical length of the container support (12). The lower punch (20a) is provided in such a manner that it can move through the movement path (15) and come into contact with portions of the lower surface of the container (3) other than the above-described portion thereof.

Disclosed is an engine system with a reformer, the engine system comprising a reformer and driving an engine using, as a fuel, a reformed fuel produced by reforming pre-reformed fuel with the reformer, in which the reformer is connected with both a pre-reformed fuel supply adjustment unit which adjusts the amount of the pre-reformed fuel supplied to the reformer and a reformed fuel supply adjustment unit which adjusts the amount of reformed fuel supplied to the engine, and the reformer is installed adjacent to the engine combustion chamber via the reformed fuel supply adjustment unit.
摘要:
The present invention relates to a system wherein a pair of relatively movable, facing DLC contact surfaces at least one of which is coated with a DLC film, are further lowered in friction, and the low friction property is stably maintained. The present invention also relates to a lubricant for the system, and a lubricating method. The lubricant for the system having the DLC contact surfaces contains lubricant base oil (A) mainly composed of base oil (X), and sulfur-containing molybdenum complex (B). The base oil (X) is at least one of hydrocracked mineral oils, wax-isomerized mineral oils, and poly-α-olefin base oils, and has a kinematic viscosity of 2 to 20 mm2/s at 100° C., a total aromatic content of not higher than 5 mass %, and a total sulfur content of not higher than 0.005 mass %.

A fuel supply and collection system comprising: a delivery vehicle having a supply-fuel tank, a collection-fuel tank, a remaining supply-fuel quantity sensor for detecting a remaining fuel quantity of the supply-fuel tank, a remaining collection-fuel quantity sensor for detecting a remaining fuel quantity of the collection-fuel tank, and a display unit; a plurality of fuel stations having a supply-fuel tank, a collection-fuel tank, a remaining supply-fuel quantity sensor for detecting a remaining fuel quantity of the supply-fuel tank, and a remaining collection-fuel quantity sensor for detecting a remaining fuel quantity of the collection-fuel tank; and a central information processing center having an information processing apparatus; wherein, the remaining supply-fuel and collection-fuel quantities of the delivery vehicle and the remaining supply-fuel and collection-fuel quantities of each fuel station are estimated in the information processing apparatus from remaining supply-fuel quantity data and remaining collection-fuel quantity data detected in the delivery vehicle and remaining supply-fuel quantity data and remaining collection-fuel quantity data detected at each of the fuel stations; supply and collection priority order of each fuel station are calculated from the estimated remaining supply-fuel and collection-fuel quantity data of each fuel station; a driving route of the delivery vehicle is determined based on the estimated remaining supply-fuel and collection-fuel quantity data of the delivery vehicle and the supply and collection priority order of each fuel station; and the determined driving route is displayed on the display unit in the delivery vehicle.
摘要:
Recovery of dehydrogenation product must be done separately from supply of hydrogen fuel. However, there is a problem that it takes much time when dehydrogenation product recovery and fuel filling are done separately. A fuel filling/waste solution recovery apparatus includes measuring means to measure a volume of supplied fuel and a volume of recovered waste solution by measuring flow rates of solutions passing through a fuel filling nozzle and a recovery nozzle or piping, and a display which shows the volume of supplied fuel and the volume of recovered waste solution which are measured by the measuring means.
摘要:
An engine system comprises a detection means for detecting a supply quantity or supply pressure of hydrogen rich gas which is disposed in a hydrogen rich gas supply pipe for supplying hydrogen rich gas to a combustion chamber of the engine, a hydrogen rich gas supply valve control means for controlling the supply of hydrogen rich gas by controlling the open/close timing and the amount of open/close lift of the hydrogen rich gas supply valve disposed in the combustion chamber of the engine based on the supply quantity or supply pressure detected by the detection means, an inlet valve for supplying air to the combustion chamber of the engine separately from the hydrogen rich gas supply valve, and an inlet valve control means for controlling the volume of air taken into the combustion chamber of the engine by the inlet valve.
