摘要:
In an apparatus for producing trichlorosilane, an internal space of a reaction chamber is partitioned in a radial direction by first walls running along a circumferential direction, and is partitioned into multiple spaces by second walls which extend in a direction crossing the circumferential direction. Upper portions or lower portions of the first walls and the second walls are formed with a communicating portion which circulates a raw material gas to be introduced, toward a central portion of a reaction chamber while the raw material gas goes through the small spaces sequentially and is turned up and down, heaters are installed in the small spaces, one of small spaces on both sides of the second walls is used as a small space for a upward flow passage, and the other is used as a small space for a downward flow passage, and the small spaces communicate with each other via the communication portion of the second walls.

When a monochromatic copy mode is to be executed, a control section sets a read mode in a scanner section so as to enable the scanner section to read an image at high speed by means of only a line sensor K, sets in an image processing section an image process that can print monochromatic image information, which is sent from the scanner section, with a single black color in the printer section, and sets in the printer section a monochromatic print mode that can print a black image at high speed, thereby controlling a monochromatic copy operation.

Gas discharge ports are provided in almost the entire area of a layer surface of a separator, and a gas for reaction is discharged like a shower from the separator toward a power generation cell. The separator is constructed by layering plate-shaped members containing iron-base alloy, nickel-base alloy, or chrome-base alloy as the base material. Silver, silver alloy, copper, or copper alloy is plated on both sides or one side of the base material of the plate-shaped member. The construction above can increase durability of a separator and enables the separator and a solid oxide fuel cell to be stably used for a long period.

A technique that can perform appropriate image quality control processing corresponding to fluctuation in a printing environment is provided. An image forming apparatus that forms, on a sheet, a test pattern formed by a color obtained by mixing toners of plural colors, scans a test pattern image formed on the sheet with a color sensor, and performs predetermined image quality control processing on the basis of information scanned, the image forming apparatus including a media sensor that acquires information for discriminating a type of a sheet to be an object of image formation processing, a control-information acquiring unit that acquires, on the basis of the information acquired by the media sensor, information for control used in the image quality control processing, and a color sensor that is arranged further on a downstream side than a fixing device in a sheet conveying direction and scans the test pattern formed on the sheet.

An image forming apparatus includes an image area identification unit to discriminate a character area and a line drawing area from an image area with respect to an image formed based on inputted color image data, an edge detection unit to detect an edge of a character and a line drawing, which is identified, and an edge γ correction unit to perform, only in a case where the edge exists on a white ground area in the image, thinning to lower an image density of a pixel on an outer border corresponding to the edge on the white ground area.
