Abstract: In a control device which controls a printing press, a capturing unit captures an inspection target object printed on a target printed material by the printing press, and outputs RGB values of each pixel of a captured image. The converter specifies a pixel with respectively equal RGB values and a pixel with respectively approximating RGB values as pixels in the grayscale area in the image, and converts the RGB values of each pixel other than the grayscale area into HSV values. An extractor extracts a pixel of an extraction target color from the image based on the RGB values in a case of the pixel in the grayscale area, and the HSV values in a case of the pixel other than the grayscale area. The controller controls the printing press to correct the print misalignment based on the pixels of the extraction target color extracted by the extractor.

Abstract: There is provided an economical carburizing method and carburization apparatus capable of carrying out carburizing treatment with a quality as high as that in a normal case and a high reproducibility even if carburizing conditions differ from those in a normal case. A carburization apparatus for carrying out carburization in an atmosphere gas containing not more than 30% by volume of carbon monoxide under a pressure of 13 to 4,000 Pa has a carburizing chamber 3 for housing an object 4 to be treated; an oxygen sensor 20 for measuring an oxygen concentration in the atmosphere gas in the carburizing chamber 3 during carburization; and a mass flow controller 5 for adjusting a composition of the atmosphere gas in the carburizing chamber 3 according to a measurement result by the oxygen sensor 20.

Abstract: A switch includes a switching mechanism, an operating mechanism with a key which normally causes the switching mechanism to be in a switched-off condition when it is pulled out and to be displaced against a biasing force to be in a switched-on condition when the key is inserted, and a locking mechanism for maintaining the switching mechanism locked in the switched-on condition and releasing it from the locked condition if a load greater than a specified magnitude is applied to the key while the switching mechanism is locked such that the switching mechanism is set back in the switched-off condition. The switching mechanism may be contained in a head case attached to a main case containing the operating mechanism. The main case also includes a forcing mechanism which tends to force the switching mechanism in the switched-off condition.
