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: The check valve (1) is of straight pipe joint type and oblique lift type. It includes: a valve seat (12a); a moving body (2) capable of linearly reciprocating between a closed state where it is in close contact with the valve seat and an open state where it is separated from the valve seat; a primary flow path (inflow path (12c)) on an upstream side of the moving body; and a secondary flow path (outflow path (12d)) on a downstream side of the moving body. The moving body includes a valve body (6) and a valve shaft (7) extending from the valve body. The valve seat supporting the valve body is formed to straddle the center line (CL) of the connection flow path that linearly extends including the primary flow path (inflow path) and the secondary flow path (outflow path 12d) in a cross section including the center line thereon.

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.
