Abstract:
A hydrogen-fueled internal combustion engine that uses liquid hydrocarbon fuel and hydrogen gas as fuel, which improves mixability of liquid hydrocarbon fuel and hydrogen gas and reduces the number of parts required for a fuel supply that supplies the two types of fuel. The hydrogen-fueled internal combustion engine includes a fuel injection device injecting hydrocarbon fuel; a fuel supply supplying hydrocarbon fuel to the fuel injection device; and a microbubble generation device generating microbubbles of hydrogen gas and mixing the generated microbubbles of hydrogen gas into liquid hydrocarbon fuel in the fuel supply. The hydrogen gas microbubbles are supplied, for instance, to a fuel supply path and fuel tank, which constitute the fuel supply.

Abstract:
In a gas-fueled internal combustion engine, an ignition device (16, 6O, 62, 64, 66) is arranged in a moving direction of a stream of the gaseous fuel injected from an in-cylinder injection valve (40) in a combustion chamber. The ignition device can directly ignite the fuel stream and diffusive combustion of the gaseous fuel can be executed by sequentially injecting the gaseous fuel toward a flame created by the ignition. Further, premix combustion of the gaseous fuel can also be performed by igniting an air-fuel mixture after the gaseous fuel injected from the in-cylinder injection valve has been sufficiently mixed with the air. As an operation mode of the engine, a lean premix combustion operation is selected when the engine is operated in a prescribed operation region, and the operation mode is changed to a diffusive combustion operation when the engine is operated in a higher load operation region than the prescribed operation region.

Abstract:
In an internal combustion engine using hydrocarbon fuel and hydrogen gas as fuels and including a fuel injection device that injects liquid fuel, a hydrogen-blended fuel in which hydrogen gas is contained in the form of minute bubbles in a liquid hydrocarbon fuel, that is supplied to the fuel injection device. The hydrogen-blended fuel is stored in a fuel tank. Hydrogen gas that has escaped from the hydrogen-blended fuel in the fuel tank is fed to a minute-bubble producing device, which forms the fuel gas into minute bubbles and mixes the minute bubbles back into the hydrogen-blended fuel.

Abstract:
An image forming apparatus includes a plurality of functions including a function of executing an operation involving use of a consumable, a selecting unit that selects one function from the plurality of functions, a detector that detects a remaining level of the consumable and a controller. The controller is operable to switch displayed contents to information corresponding to the one function when the one function is selected, instruct execution of an operation corresponding to the changed displayed information, display a warning indication when the remaining level of the consumable is not more than a predetermined level, determine whether the selected one function is the function of executing the operation involving use of the consumable, and inhibit the switching the displayed contents when one function is selected and is determined to be the function of executing the operation involving use of the consumable while the warning indication is displayed.
Abstract:
Photoelectric conversion elements of line sensors (CIS22 to CIS26) arranged in a zigzag manner read a white reference plate to acquire a white reference read value A, and a white reference read average value AA is determined from the white reference read value A for each line sensor. Further, the photoelectric conversion elements read another white reference plate placed on a document support plate to acquire a white reference read value B, and a white reference read average value BB is determined from the white reference read value B for each of the line sensors (CIS22 to CIS26). By using the white reference read average values AA and BB, a sensitivity effect coefficient C used for uniforming the sensitivities different because of the variation of the distances from the line sensors (CIS22 to CIS26) to the document support plate is determined by dividing the average value BB by a data processing section for each of the photoelectric conversion element of the line sensors. By using a white reference read value Aa acquired by reading a white reference plate immediately before reading a document and a black reference read value, a white reference read value Aa for shading correction for correcting a document read value E is corrected with the sensitivity offset coefficient C. In this way, irrespective of the variation of the distances from the line sensors to the document support plate, the variation of the document read values read from the photoelectric conversion element of the line sensors can be suppressed.
