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.

Abstract: An inspection device is a device that inspects the appearance of a target, including: an imaging device configured to image the target from a first direction; an illuminating unit configured to apply light to the target; and a controller configured to acquire a first inspection image by causing the imaging device to image the target to which light is applied from a first position, to acquire a second inspection image by causing the imaging device to image the target to which light is applied from a second position, and to inspect an appearance of the target based on the first inspection image, the second inspection image, and a reference image. The first position and the second position overlap each other when viewed from the first direction.

Abstract: A casting plant to produce a cast product with a high quality and a method for managing data for molding the mold and data on the conditions of the molten metal in the casting plant are provided. The controller (11) for the molding unit issues a serial number for the mold to a mold (M). The controller (31) for the unit for conveying the molds shifts the serial number for the mold in accordance with a movement of the mold. It also gathers data on the mold and links the data for molding the mold with the serial number for the mold. When the molten metal is poured from the ladle into the mold, the controller (71) for the unit for pouring the molten metal sends to the computer (91) for controlling the casting plant the serial number for the ladle that is linked with the data on the conditions of the molten metal and that is linked with the serial number for the mold.

Abstract: Provided is the technique that allows an operator or the like to easily grasp a defect contained in a mold. A display control device is configured to carry out: a determination process in which a feature amount of each of defects contained in a mold is determined with reference to an image obtained by image capture of a mold; and a display process in which the image is displayed on a display such that each of the defects in the image is emphasized by a method which is determined according to the determined feature amount.

Abstract: Provided is the technique that allows an operator or the like to grasp a failure of a mold to be worked in the work area. An inspecting device inspects each of a plurality of molds conveyed along a conveyance path with use of image data generated by a sensor that captures an image of each of the plurality of molds. A display control device is configured to carry out: a storage process in which inspection results of the individual molds are stored in a memory; a determination process in which one or more molds satisfying a predetermined condition of a positional relation to a display are determined from among the plurality of molds conveyed along the conveyance path; and a display control process in which one or more inspection results of the respective one or more molds having been determined in the determination process are displayed on the display.

Abstract: To provide a surface property inspection device and method capable of inspecting the surface treatment state of treated material subjected to surface treatments. A surface property inspection device 1 includes an AC power supply 10, an AC bridge circuit 20, and an evaluation apparatus 30, and the AC bridge circuit 20 is formed by a variable resistor 21 with a distribution ratio of γ, a reference detector 22, and an inspection detector 23. The inspection detector 23 includes a coil 23b wound so as to oppose the surface property inspection area of the test object M; an eddy current is excited in the test object M by supplying AC power to the coil 23b. A reference test object S with the same structure as the test object M is placed in the reference detector 22 to cancel inspection environment effects.
