    Abstract: [Problem] To provide a method and device that automatically detects misalignment during flask mating in an automatic flask mating device for molding flasks for casting.[Solution] In an automatic flask mating device, an external force applied to a cope with a cope molding flask M1 during flask mating is detected by means of a physical quantity detection sensor 60, quantified by a computation/storage/determination processing device 61, and then compared with a numerical value at a normal time for determination to thereby determine whether the flask mating has normally completed and detect flask mating misalignment. A force sensor is preferably used as the physical quantity detection sensor.

    Abstract: [Problem] To provide a main mold and core setting device and a main mold and core setting method which enable core setting work, hitherto implemented by a core setting operator using subtle hand sensation, to be completely reproduced by automation.
    [Solution] The present invention is provided with: a core grasping and moving means for grasping and moving a core; a core movement amount detection means for detecting a movement amount of the core grasping and moving means; a grasped core position and posture detection means for detecting a position, orientation, and inclination of the core grasped by the core grasping and moving means; a main mold position and posture detection means for detecting a position, orientation, and inclination of a main mold; a sensor for detecting a physical quantity applied to the core; and a control means for constantly calculating relationships between relative positions, orientations, and inclinations of the main mold and the core, and from these relationships and the physical quantity applied to the core detected by the sensor, controlling the core grasping and moving means so that the core is caused to set with the main mold.

    Abstract: To provide a decompressing jig that can apply pressure on a workpiece after a space for accommodating the workpiece is sufficiently decompressed and a method for applying pressure on a workpiece by using the decompressing jig. The decompressing jig 1 is configured by integrating a first member for decompression 10, a second member for decompression 20, a sealing member 30, a first member for preliminary decompression 40, and a second member for preliminary decompression 50. The first member for decompression 10 is formed by spreading a first sheet 12 made of a flexible sheet across a first frame 11. In the first frame 11 a path for suction 15 that is connected to a device for suction via a port for suction 14 and that is connected to a space S for accommodating the workpiece is formed. The first member for preliminary decompression 40 forms a chamber Y for preliminary decompression between it and the first sheet 12 so that the chamber Y can be decompressed.

    Abstract: A strain element (10), which is configured such that a frame portion (11) and a central portion (12) are connected by arm portions (20) to (22), is masked except for the arm portions (20) to (22) where a strain gauge (A1) and the like are to be disposed, and then peening is carried out. With this, a compressive residual stress layer is formed on four sides of each of the arm portions (20) to (22). When the strain element (10) receives a load resulting from an external force, the arm portions (20) to (22) elastically deform; however, due to the compressive residual stress layer thus formed, the arm portions (20) to (22) are less prone to fatigue failure. When projection of a shot material is carried out as peening, the surface roughness of the arm portions (20) to (22) increases, the adhesion of strain gauges improves, detection accuracy improves, and stable measurement can be ensured.
