Object: To provide a hydrogen generation apparatus, a laser reduction apparatus, an energy conversion apparatus, a hydrogen generation method and an electric power generation system.Means for Solving the Problems: A hydrogen generation apparatus 10 according to the present invention includes: a reaction vessel 12 for retaining a metal element; a water reservoir 16 for supplying water into the reaction vessel 12; and a hydrogen recovery tube for recovering hydrogen gas and reaction energy generated by reaction of the metal element with the water. The present invention may further include a hydrogen storage device 26 for storing recovered hydrogen gas. Further, in the present invention, an oxide or a hydroxide of the metal element generated by reducing the hydrogen gas may be subjected to laser reduction to regenerate the metal element. A solar light pumped laser may be used for laser reduction. Further, according to the present invention, there may be provided an energy conversion apparatus for generating an electric current by using charged particles formed due to the laser reduction, and an electric power generation system using the above hydrogen generation system.

Input print data can assume one of a RGB color space, CMYK color space, and Gray color space. When graphic arts are principally to be printed, data of these color spaces is converted into CIE Color Space XYZ as a standard color space, and data of the standard color space is converted into a CMYK color space according to the Output Profile of a printer, which then prints the converted data. On the other hand, when office documents are principally to be printed, conversion into the standard color space is skipped, and input color space data is directly converted into a print color space CMYK, and the converted data is then printed.

A heat exchanger includes a pair of header tanks, a plurality of flat heat exchange tubes which are disposed between the two header tanks and whose opposite end portions are connected to the corresponding header tanks, and a plurality of corrugate fins each including wave crest portions, wave trough portions, and connection portions connecting together the corresponding wave crest portions and wave trough portions, and each disposed between the adjacent heat exchange tubes. Each connection portion has a plurality of louvers which extend in a width direction of the connection portion and are arranged in a longitudinal direction of the connection portion. The louver pitch is 0.4 mm to 0.8 mm. The inclination angle of the louvers in relation to the connection portion is 20° to 30°. When this heat exchanger is used as a heater core, excellent heat radiation performance can be attained, and an increase in resistance to air flow can be prevented.

A color image processing system includes storage of plural specific color data representing a gamut of an output device and judgment of whether input color image data is within the gamut of the output device, the judgment performed based on a positional relationship among a plane defined by the plural specific color data, predetermined color data within the gamut of the output device, and the input color image data.
摘要:
An image processor includes an input device that inputs image data representing a target image, and a color gamut mapping device that performs a color gamut mapping process. The image processor also includes a color reproduction process device that performs a color reproduction process, and a judgement device that judges whether a monochromatic mode for forming an image on a recording medium is set. A controller controls the color gamut mapping device and the color reproduction device, with the controller inhibiting the color gamut mapping device from performing a color mapping process on the input image data when a judgment is made that the monochromatic color mode is set.
摘要:
High-purity silicon is collected, and the amount of carbon dioxide is effectively curtailed. Oxygen is released from the first or second oxide by irradiating a mixture or compound of a first oxide such as magnesium oxide, potassium oxide, or calcium oxide and a second oxide such as carbon dioxide or silicon monoxide with a laser.
摘要:
An image processing apparatus determines whether a color image is formed by reading an original with a reading unit or input from an external apparatus, and sets a conversion method for converting the color image into a monochrome image such that when an image obtained by monochrome converting the color image is output onto a recording medium, security information included in the color image is difficult to be discriminated by human eyes, if the color image is formed by reading an original. If the color image is input from the external apparatus, the image processing apparatus sets a monochrome conversion method selected by a user. The apparatus then converts the color image into a monochrome image by the set monochrome conversion method.
摘要:
An image processor and an image processing method which can minimize variation of color tone or density in an image after screen processing, even if semi-transparency has been specified. The image processor generates semi-transparent image data by overlaying a semi-transparent object on the PDL data to be rendered semi-transparent. Subsequently, screen processing is performed on the semi-transparent image data, by dither processing. Subsequently it is determined whether or not to define the screen processed semi-transparent image data as the image data for printing. If the result of determination is No, the halftone value of the semi-transparent object is modified to be larger than the current value.
摘要:
A convenient environment flexibly coping with an environment in which an image forming apparatus capable of accepting a plurality of jobs is used can be constructed. For this purpose, in a job processing method of an image forming system including the image forming apparatus capable of accepting a plurality of jobs including a first job, print processing of the first job is performed by the image forming apparatus, and performance of print processing of a second job input after the first job can be prohibited based on checking information including at least any one of information associated with the first job subjected to the print processing and information associated with the second job although print processing of the second job can be performed by the image forming apparatus.
摘要:
A heat exchanger to be used as a heater core includes a pair of header tanks spaced apart from each other, a plurality of flat heat exchange tubes which are disposed between the two header tanks at predetermined intervals along a longitudinal direction of the header tanks with their width direction coinciding with an air flow direction and whose opposite end portions are connected to the header tanks, and a plurality of corrugate fins each disposed between the adjacent heat exchange tubes. Each heat exchange tube has an inner height Ht of 1.2 mm to 1.7 mm and a width of 18 mm to 24 mm as measured in the air flow direction. Each corrugate fin has a fin height Hf of 4.0 mm to 7.5 mm. This heat exchanger exhibits excellent heat radiation performance and low resistance to air flow and water flow.
