A combustor includes a chamber mixing and burning fuel and air and an air hole plate disposed on a wall surface of the chamber. The, air hole plate includes a plurality of rows disposed concentrically of a plurality of air holes jetting coaxial jets of fuel and air into the chamber. A first fuel nozzle and a second fuel nozzle are disposed near a fuel hole for jetting fuel into an air hole row on an inner peripheral side. The first fuel nozzle is structured to suppress turbulence of a surrounding air flow and the second fuel nozzle is structured to promote turbulence of a surrounding air flow. In accordance with the aspect of the present invention, good flame stability can be maintained while further reducing NOx in a combustor using coaxial jets.

An apparatus, method, and program product for monitoring execution of a program, reducing overhead and not changing the behavior of the program. The apparatus performs additional processing which requires a memory area upon execution of a specific instruction to be executed by a predetermined execution system on a computer. The system includes a memory reservation unit reserving the memory area for the additional processing, an instruction replacement unit copying the specific instruction to the reserved memory area and replacing the specific instruction with a special-purpose instruction, an additional processing execution unit acquiring the memory area, and a replaced instruction execution unit performing the same processing as that performed by the specific instruction.

A combustor comprises a liquid fuel nozzle for injecting liquid fuel to a combustion chamber, and an air supply nozzle disposed around the liquid fuel nozzle and injecting air. The air supply nozzle is disposed such that air is injected from the air supply nozzle in a direction toward an axis of the liquid fuel nozzle. A space is formed around an outlet of the liquid fuel nozzle, through which the liquid fuel is injected from the liquid fuel nozzle to the combustion chamber, upstream of a distal end of the outlet in a direction in which the liquid fuel is injected. Carbonaceous deposits on surrounding surfaces of the outlet of the liquid fuel nozzle can be suppressed regardless of the operating conditions of a combustor.

A high-pressure pump for supplying fuel to a fuel rail includes a pressurizing unit, a discharging unit, a return flow channel, a mechanical pressure relief valve, a cup-like shaped spring seat, and a constant residual pressure valve. The return flow channel is closed when pressure of fuel in the fuel rail becomes equal to or less than a predetermined pressure. The spring seat has a guide portion that is formed along an outer shape of a constant residual pressure valve element of the constant residual pressure valve such that the guide portion limits a vortex flow generated at a position downstream of the constant residual pressure valve element in the second flow direction.

The invention provides a discolorable ink composition which is irreversibly erasable by heating to about 40° C. to 120° C. A discolorable ink composition, where an electron-donating color-forming organic compound and an electron-accepting compound are incorporated in wax particles, whereby the electron-donating color-forming compound in a state color-developed by the electron-accepting compound is separated from a decolorizer and kept in the color-developed state, while when the wax is liquefied by heating, the decolorizer reacts with the electron-accepting compound to convert the electron-donating color-forming organic compound into a decolorized state.

A liquid droplet ejection head includes: a nozzle plate that has a plurality of nozzles ejecting a liquid droplet; a flow path member that includes: pressure generating chambers that communicate with the nozzles; and liquid supply paths through which liquid is supplied to the pressure generating chambers; and a damper portion that is disposed in at least one part of a region, the region being on the nozzle plate, corresponding to the liquid supply paths, the damper portion reducing a fluctuation of an ejection amount of the liquid droplets to enable stable ejection.
摘要:
A printhead of an ink jet printer includes plural ejection nozzles for ejecting ink. In an ink ejection inspecting method for the printhead, the ejection nozzles are photographed in the printhead, to output image data. The image data is analyzed by the pattern recognition, to output analysis result information. According to this, it is judged whether an ejecting state of the ejection nozzles is acceptable or unacceptable.
