Abstract: An adjusted image data generating device includes storage and an adjusting section. The storage stores color reference data of a color reference therein. The adjusting section generates adjusted image data by adjusting an object image for image data representing a color reference image and the object image so that color data of a color reference image matches the color reference data. The color reference image is an image of a color reference. The image data is an image of an object.

Abstract: A color difference adjustment image data generation method includes generating a color signal conversion table, generating adjusted image data, and generating color difference adjustment image data. The color signal conversion table is used for converting color signals in one of a color difference adjustment image data generating device and a display device into color signals in the other. The adjusted image data is generated by adjusting image data of a display object so that color of an image of the display object being displayed by the color difference adjustment image data generating device according to the image data matches color of the display object. The color difference adjustment image data is generated based on the adjusted image data and the color signal conversion table.

Abstract: In order to detect an operating state of equipment, when a plate material reaches a support part, a press machine outputs a start signal to move a press part downward. An input receiver receives input of the start signal. An operating detector detects that the press machine is in an operating state. When the press machine moves the press part upward, and shaping of the plate material ends, the press machine outputs a standby signal. The input receiver receives input of the standby signal. The detector detects that the press machine is in a standby state. When the plate material is again conveyed onto a roller conveyer from the support part, the press machine outputs a stop signal. The input receiver receives input of the stop signal. The detector detects that the press machine is in a stop state.

Abstract: In manufacturing a rolling bearing, at least one component of an inner ring, an outer ring, and a rolling element is manufactured from an alloy steel comprising 0.05 weight %-0.5 weight % carbon, 0.5 weight %-18 weight % chromium, 1.5 weight % or less silicon, 5 weight % or less molybdenum, 4.0 weight % or less vanadium, 4 weight % or less nickel, and 8 weight % or less tungsten, by subjecting the alloy steel to carburizing, hardening and tempering. The carburizing is carried out by vacuum carburization. In the vacuum carburization, carburizing and diffusion are carried out by introducing an acetylene-based carburizing gas in a hot atmosphere under reduced pressure, followed by hardening and tempering. The use of the vacuum carburization enables carburization with the chromium (Cr) content being 3.0 weight % or more, and even up to 18 weight %, which was difficult to achieve with the conventional gas carburization (pre-oxidation+gas carburizing).
