  • Patent number: 11084299
    Abstract: A printing system is provided and includes an image processing portion that generates a generated image by image processing, and a printing portion that performs printing on a medium based on the generated image. The image processing portion generates the generated image by performing a quantization processing that performs quantization by comparing the pixel value of each pixel in the input image with a threshold, and in the quantization processing, calculates a dot influence value indicating to what extent a position corresponding to a selected pixel is covered by the ink dots formed at the position set on the medium in correspondence with the peripheral pixels of the selected pixel, performs adjustment of reflecting the dot influence value on at least one of the pixel value of the selected pixel or the threshold, and compares the pixel value and the threshold based on a value after adjustment.

  • Patent number: 9982710
    Abstract: A crankshaft of an in-line, four-cylinder internal combustion engine has five journal portions. The journal portions are each supported by a main bearing unit. Each of the main bearing units includes a cylinder block side bearing part and a bearing cap. The No. 1, No. 2, No. 4 and No. 5 main bearing units employ an iron-based bearing cap, and the No. 3 main bearing unit at the center employs a bearing cap made of an aluminum alloy having a relatively high thermal expansion coefficient. At high temperatures, the bearing clearance of the No. 3 main bearing unit is configured to expand so as to reduce bearing load.
