摘要: Arrangements for inspecting a specimen on which plural patterns are formed; capturing a first image of a first area; capturing a second image of a second area in which patterns which are essentially the same with the patterns formed in the first area; creating data relating to corresponding pixels of the first and second images, for each pixel; determining a threshold for each pixel for detecting defects directly in accordance with the first and second images; and detecting defects on the specimen by processing the first and second images by using the threshold for each pixel and information of a scattered diagram of brightness of the first and second images, wherein the threshold is determined by using information of brightness of a local region of at least one of the first and second images, with the local region including an aimed pixel and peripheral pixels of the aimed pixel.

摘要: In an extruder or a kneader, load (torque T) values on an input shaft portion of a screw shaft are detected by a load detector installed on the input shaft portion, then an overload condition is determined from a load mean value (Ta) and a load amplitude value (Tw) of the detected load values, and the issuance of an “abnormal” alarm and/or the stop of rotation of the screw shaft are (is) performed when an overload duration time (t0) of maintaining the overload condition exceeds a set time (ts). In this way the screw shaft is protected from fatigue fracture caused by application thereto of such a load as does not exceed a designed mechanical strength but causes fatigue fracture.
