Against the resultant spring surface, a number of fine metal particles having a mean diameter of all particles of 80 &mgr;m or less, a mean diameter of each particle in the range between 10 &mgr;m inclusive and less than 100 &mgr;m, a spherical or near spherical shape with no square portions, a specific gravity of 7.0 to 9.0, and hardness which falls in the range between Hv 600 and Hv 1100 inclusive and is equal to or less than the hardness of the outermost surface layer of the spring after nitriding, at a velocity of 50 to 190 m/sec., while controlling temperature to be low enough to cause work hardening but not to cause softening due to recovery/recrystallization, to provide a high compression residual stress in a near surface layer without generation of microcracks in the surface layer and thus obtain a valve spring and the like excellent in fatigue strength.

    摘要： An automatic control apparatus in a printing press includes plate replacing units, an ink presetting portion, and a test printing control unit and a CPU. Each plate replacing unit mounts a printing plate on a circumferential surface of a plate cylinder. The ink presetting portion forms, in a roller group of an ink supply unit, an ink film thickness distribution corresponding to an image of the printing plate which is to be mounted on the plate cylinder. The test printing control unit and the CPU control the plate replacing units and the ink presetting portion to automatically perform, as a series of work steps, at least a mounting operation of mounting the printing plate on the plate cylinder and a forming operation of forming the ink film thickness distribution corresponding to the image of the printing plate.

    摘要： The apparatus includes a print switch, the remaining paper detection apparatus, and a controller and a remaining paper detection controller. The print switch sets a printing press to a printing operation mode. The remaining paper detection apparatus detects remaining paper sheets on a convey board. The controller and remaining paper detection controller inhibit the print switch from setting the printing operation mode when a remaining paper sheet is detected by the remaining paper detection apparatus.

    摘要： An apparatus includes an image-processing-unit that generates tag information indicating whether each of pixels of a first-resolution image data is a pixel of a character or a line, a resolution-converting-unit that converts the first-resolution image data to image data with a second resolution higher than the first resolution, and a light-source-driving-unit that drives light-source according to the second-resolution image data. The resolution-converting-unit includes an image-matrix-acquiring-unit that acquires an image matrix being image data and tag information with the first resolution in an area containing a target-pixel and pixels around the target-pixel, a pattern-matching-unit that determines whether the target-pixel is a pixel of an edge of a character or a line based on the image matrix, and a first-converting-unit that, when the pixel is the edge pixel, converts the image data to image data with the second resolution of a pattern determined in accordance with a layout of the target-pixel.

    摘要： An image forming apparatus includes: a pseudo-halftone processing unit that processes input image data to output image data of first resolution; a resolution converting unit that converts the image data of the first resolution into image data of second resolution that is higher than the first resolution; a modulation-signal generating unit that generates a modulation signal obtained by modulating the image data of the second resolution according to a clock signal; and a light-source driving unit that drives a light source according to the modulation signal. The pseudo-halftone processing unit converts a region of pixels having the same pixel value into a parallel line pattern that is formed with a plurality of parallel lines oblique relative to a direction of arrangement of pixels. The resolution converting unit generates the image data o in which each edge of the lines forming the parallel line pattern is smoothed.
