Abstract: An electromagnetic relay includes a fixed contact holder, a moving contact holder, an electromagnetic device, and a magnet. The fixed contact holder extends in a predetermined direction and is provided with a fixed contact. The moving contact holder also extends in the predetermined direction, and is provided with a moving contact. The magnet is arranged perpendicularly to an opening/closing direction of the fixed contact and the moving contact. A stretch space in which an arc generated between the fixed contact and the moving contact is stretched is provided, in the predetermined direction, beyond respective tips of the fixed contact holder and the moving contact holder. The stretch space also faces a surface of the fixed contact holder and a surface of the moving contact holder.

Abstract: An extraction unit acquires a first difference between a non-defective product image, covering a non-defective product sample, and a reference model and a second difference between a defective product image, covering a defective product sample, and the reference model. A extraction unit extracts, as a potential defect, either the first difference or the second difference, whichever satisfies a particular condition. A calculation unit calculates at least one feature quantity with respect to the potential defect extracted by the extraction unit. When the defective product sample includes a plurality of defective product samples and respective feature quantities of the potential defects extracted from the defective product samples have multiple different values, the calculation unit specifies at least one of the feature quantities that has an Nth largest one of the multiple different values as an indicator. The presentation unit presents the indicator specified by the calculation unit.
