Abstract: Provided is a tire that can satisfy both low heat build-up property and fracture resistance at a higher level than conventional tires. The tire has a center gauge of not less than 50 mm and contains a rubber composition obtained by blending less than 20 parts by mass of a silica with respect to 100 parts by mass of a rubber component, along with a thiuram-based accelerator, a sulfenamide-based accelerator, and a resin.

Abstract: An image formation apparatus which includes a reader-writer that carries out reading of data from a storage medium provided for paper and writing of data to the storage medium provided for the paper, a document data acquisition section that acquires original document data to be printed on the paper, a determination section that determines whether the paper has the storage medium, and a printing out section that, when it is determined that the paper does not have the storage medium, carries out ordinary printing on the paper on the basis of the original document data, and when it is determined that the paper has the storage medium, carries out printing an image corresponding to the original document data on the paper on the basis of the original document data, and carries out writing and outputting of the original document data to the storage medium provided for the paper.

Abstract: It is judged whether or not an exchange unit mounted in an image forming apparatus is a genuine one. If judged that a nongenuine unit is mounted there, it is judged at the next step whether not a control parameter is optimized. If judged that the control parameter is optimized, it is judged at the next step whether or not the control parameter is optimized in a local environment. If not optimized in the local environment, an optimal parameter is downloaded from a website.

Abstract: It is judged whether or not an exchange unit mounted in an image forming apparatus is a genuine one. If judged that a nongenuine unit is mounted there, it is judged at the next step whether not a control parameter is manually optimized. If judged that the control parameter is manually optimized, it is judged at the next step whether or not the control parameter is optimized in a local environment. If not optimized in the local environment, an optimal parameter is downloaded from a web at step.

Abstract: An image formation apparatus is determined whether a replacement unit attached to the image formation apparatus is a genuine product or a product other than the genuine product, and the image formation apparatus is determined whether the replacement unit is a recycled product or not. When the image formation apparatus is the recycled product and the image formation apparatus is determined that recycling display is performed, the recycling display is added to a print. The image formation apparatus is controlled in a genuine product mode when the replacement unit is the genuine product, and is controlled in a non-genuine product mode when the replacement unit is the product other than the genuine product.

Abstract: A color space conversion device for executing color space conversion from RGB data to CMYK data comprises a color space conversion circuit, a CMY position detection circuit, three UCR/BG tables, a continuation table and a UCR/BG synthesizer circuit. The color space conversion circuit converts RGB data into C′M′Y′ data. The CMY position detection circuit 2 detects the position of the C′M′Y′ data in the CMY color space with respect to each dot of the C′M′Y′ data. Each of the three UCR/BG tables has been optimized at particular position (in the achromatic color area, an intermediate area, and the high chroma area) in the CMY color space so as to be used for color space conversion from C′M′Y′ data to CMYK data. The continuation table outputs continuation parameters based on the position of the C′M′Y′ data.

Abstract: A print data processing technique for a printer device is disclosed. There has been stored error data in halftone level between an actual halftone characteristic of the printing device and a target halftone characteristic. After dividing input print data into halftone cells of a predetermined pattern to produce halftone-cell data for each of the halftone cells, the error data of a halftone cell is sequentially diffused over halftone-cell data of another halftone cell using a predetermined distribution ratio from the halftone cell to the other halftone cell to correct halftone-cell data of each of the halftone cells. Dither data of each of the halftone cells is produced from corrected halftone-cell data thereof.
