    摘要： In the preparatory stage, among all possible lines in two rectangular windows (12) and (14), assuming dust, a flaw or the like to be a part of a line, the most valid one is recognized as a line, and the inclination and characteristic values of the line are obtained, and then each rectangular window is deformed into a parallelogram-shaped window along this inclination. In the detecting stage, the inclination and characteristic values of the line to be detected are obtained by use of the parallelogram-shaped windows. Thus, even if image data is inferior, the detection of a line is possible, so that it is possible to detect a weld line, an edge of an object of detection, etc. with high accuracy.

    摘要： When a brake is released by worker's operation, a subject automatic machine is specified so as to prevent an accident due to an error, such as misconception. An automatic machine control device includes a brake releasing unit that releases a brake when a motor is not driven, and a brake release indication unit that is provided on the automatic machines or in the vicinities of the automatic machines. When brake releasing is made by worker's operation, the fact is indicated on the brake release indication unit of a subject automatic machine.

    摘要： A rolling bearing comprises a rolling element, an outer ring having an outer circumferential surface portion subjected to surface hardening and an inner circumferential surface portion acting as an orbit of the rolling element, the outer circumferential surface portion being in contact with other members so as to be used as a roll, and an inner ring having an outer circumferential surface portion acting as an orbit of the rolling element. The hardness of a core portion of the outer ring is set to be in a range of from Hv 500 to Hv 650.

    摘要： A rolling part steel with which the strength of a rolling part of a cold-worked bearing is improved compared with that of a conventional turned part by controlling the length and number of sulfide inclusions in the steel to an optimal range, when a rolling part steel is prepared so that the maximum length of sulfide inclusions in the steel is 100 .mu.m or less and that a number of sulfide inclusions whose lengths exceed 40 .mu.m is 50 or less per unit area (160 mm.sup.2) , the roughness of its bore surface is improved to have a greater strength. As a result, for example, a thus formed raceway ring has a longer life against fatigue-induced cracks than a turned raceway ring.

    摘要： In a corrective tempering method and apparatus for a rolling element in which the thermal deformation of the rolling element is corrected within an extremely short time by utilizing plasticity exhibited during a metallic structure transforming process brought about by low-temperature tempering of the rolling element made of steel, the hardened rolling element is heated and pressured to a maximum temperature within a range of from 250 to 500° C. by a heating device while set in correcting molds to correct the deformation of the rolling element at a degree of working within a range not exceeding an elastic deformation range of the rolling element at a room temperature. The rolling element can be heated also by an induction heating device in addition to a conduction heating device. A product whose inner/outer diameter correcting degree of deformation is 60% or more, dimension standardizing rate is 30% or more, surface roughness is less than Ra 0.2 &mgr;m, and surface hardness is HRC 56 or more can be obtained for a correction time within 6 minutes and an induction heating time within 30 seconds.
