Abstract: A core inspection device for inspecting a core, the device including a color sensor configured to detect a measured value of each color component of the color of the surface of the core, and a determination unit configured to compare the measured value of at least one color component detected by the color sensor with a threshold prepared corresponding to the at least one color component, thereby determine if a strength property of the core is acceptable or not.

Abstract: A mold strength measuring device according to an aspect obtains information about strength of a mold having a product surface and a back surface opposite to the product surface. The mold strength measuring device comprising a cutting tool and a measurement probe. The cutting tool form a bottomed hole extending from the back surface toward the product surface in the mold. The measurement probe to be inserted into the hole to measure a reaction force received from a bottom of the hole.

Abstract: The strength measuring apparatus includes: a strength measuring instrument measuring the strength of the mold on the basis of a reaction force received from the mold; a moving unit moving the strength measuring instrument; a distance sensor measuring a distance to an object on the conveyance line; and a control unit controlling the moving unit, wherein the control unit determines a measurement position of the strength measuring instrument in a horizontal direction perpendicular to a conveyance direction of the conveyance line on the basis of the distance detected by the distance sensor and controls the moving unit to move the strength measuring instrument to a position above the measurement position.

Abstract: Provided is a technique that allows an operator or the like to easily perceive a tendency of defects which are present in molds or patterns. A display device displays a result of inspection of a plurality of molds or a plurality of patterns which are inspection target objects. The display device classifies the inspection target objects into a plurality of groups, generates, for each of the plurality of groups, a heat map image from a result of defect inspection of one or more of inspection target objects which are classified into the each of the plurality of groups, the heat map image representing a spatial distribution of defect occurrence frequencies; and causes a display to display one or more of the heat map images generated, the one or more heat map images corresponding to one or more groups specified by a user from among the plurality of groups.
