摘要： Provided is a defect detection device capable of measuring the volume of surface defects. The defect detection device includes: an imaging device configured to image an image of an inspection object; a binarization processing unit configured to subject the image to first and second binarization processing by use of different first and second binarization thresholds, so as to calculate first and second sizes for an identical defect in the image; a ratio calculation unit configured to calculate a first ratio of the second size to the first size; and a depth determination unit configured to determine a depth of the defect depending on the first ratio.

摘要： A manufacturing method for manufacturing a fuel cell separator assembly includes a joining step for bringing opposing projections of uneven portions of separators into contact with each other through use of pressing members to join the projections through use of a welding robot. In the joining step, an elastic member is interposed between the pressing members and at least one of first and second separators so that a pressing force from the pressing members is imparted to the first and second separators. In this way, the opposing projections are brought into contact with each other by elastic deformation of the elastic member.

摘要： A sprayed coating forming method of forming a sprayed coating includes pre-heating a cylinder block defining a plurality of cylinders, supplying air into an enclosure that houses the cylinder block, inserting a spray gun sequentially into cylinder bores formed in the cylinder block while discharging the air at least from one side of the cylinder block, and spraying droplets of a molten metal onto an inner surface of each of the cylinder bores. The spraying includes spraying one of the cylinder bores first, then next spraying another of the cylinder bores that has at least one cylinder disposed between the another of the cylinder bores and the one of the cylinder bores sprayed first. The air flows around the cylinder block and also flows inside the cylinder bores.
