Abstract: As training data that is used in generation of a prediction model, training data for a normal product which is configured by assigning a normal product ground truth label including only a normal label indicating a possibility of correspondence to a normal product to a learning image of the normal product, and training data for a defective product which is configured by assigning a defective product ground truth label including only a plurality of weighted defect type labels indicating a possibility of correspondence to a plurality of defect types to a learning image of the defective product are used. According to this, it is possible to perform defect inspection with the prediction model in which a possibility of erroneously predicting the defective product as the normal product is further reduced by setting a loss value in a case of prediction as the normal product from a learning image of the defective product to which the defective product ground truth label is assigned to be larger than a loss value in a case of prediction as the defective product in a defect type other than a ground truth from the same learning image in machine learning.

Abstract: A method of forming a setter for firing a ceramic has a sheet formation step (S1 to S3) to form a structure by sheet formation. The structure has a porous layer S1 with ceramic fibers. A shaping step S5 shapes the structure, into a predetermined shape. A coating step S6 impregnates the predetermined shape structure, with an impregnation liquid to form a dense layer S2 on the outer surface of the porous layer S1. The dense layer S2 is denser than the porous layer S1. A firing step S7, fires, at a predetermined temperature, the structure that has been subjected to the coating step S6.

Abstract: A progressive press metal mold has a lower mold 1, with a die having a plurality of die holes Da, and an upper mold 2, with punches P corresponding to the respective die holes Da, where the punches P and the corresponding die holes Da form a plurality of processing stages S. A belt-shaped metal material W is transported sequentially to perform predetermined pressing on the belt-shaped metal material W with the punches P and the die holes Da in the respective processing stages S. Electromagnets 7 are configured to attract, by magnetic force, the belt-shaped metal material W to be transported to the specific processing stage Sc.

Abstract: A clutch device includes a clutch center, and a pressure plate movable toward or away from the clutch center, rotatable relative to the clutch center, and operable to press input-side rotating plates and output-side rotating plates. The pressure plate holds the output-side rotating plates and includes pressure-side fitting teeth projecting radially outward from an outer peripheral surface of an outer peripheral wall and arranged in circumferential directions, and an oil channel in an end portion of at least one of the pressure-side fitting teeth in a first direction. The oil channel allows clutch oil flowing at least at an inner peripheral surface of the outer peripheral wall to be discharged to the outside of the pressure plate.
