  • Patent number: 11994493
    Abstract: A method identifies a cause of change in magnetic permeability of an object under inspection and evaluates the state of surface treatment(s) of the object under inspection with high accuracy. An embodiment of the method includes preparing a non-destructive inspection apparatus; placing the object under inspection; generating eddy current in the object under inspection; continuously changing the penetration depth of an AC magnetic field in the object under inspection; calculating the value of impedance at each penetration depth in the object under inspection; and evaluating the state of the surface treatment(s) by: calculating the ratio between the value of impedance at each penetration depth in the object under inspection and the value of impedance at a corresponding penetration depth in steel which has not been subjected to a surface treatment; and identifying a cause of a change in magnetic permeability of the object under inspection based upon the calculated ratio.

  • Patent number: 11986878
    Abstract: When molding surfaces (50A) of a pair of dies (50) are to be cleaned by air-blowing, air is blown towards the molding surfaces (50A) from blowing nozzles (22A) of a cleaning blowing function portion (22) while a moving body (16) is reciprocatingly moved by driving force of a driving mechanism (18). When a parting agent is to be applied to the molding surfaces (50A) of the pair of dies (50), the mold release agent is jetted out towards the molding surfaces (50A) from spraying nozzles (24A) of a parting agent application function portion (24) while the moving body (16) is reciprocatingly moved by the driving force of the driving mechanism (18). In both of these situations, at the same time as the treatment of the molding surfaces (50A), a cleaning brush (32) reciprocatingly moves together with the moving body (16) and sweeps a device floor surface (12).
