An assembly including an optically excited infrared nondestructive testing active thermography system is disclosed. An acceptable move for the game may comprise placement of a plurality of the game elements in a predetermined positional relationship; and the numerals of the game elements satisfying a predetermined mathematical relationship addition or a difference). While maintaining the identicalness of the main object, the infrared cut filter 45 is disposed above the CCD 41 to acquire visible light image data via the CCD 41, and the object is irradiated with infrared light emitted from the infrared emitters 25 and 32, and the visible light cut filter is disposed above the CCD 41 to acquire infrared image data, i. The first protective layer includes thermoplastic copolymers prepared from styrene, acrylonitrile, and optionally other addition-polymerizable monomers such as acrylate monomers, vinylbenzyl chloride, and diesters of maleic acid or fumaric acid. and subsequently subject to desalination treatment in order to synthesize an amorphous aluminum silicate.
