Some embodiments include methods of forming photomasks. The mobile device may use a blind decoding scheme to detect DCIs. The X-direction deformable body and the Y-direction deformable body are integrally molded by synthetic resin together with the support member joint portion. The thickness of the body forms an elevation from the desktop surface to allow the keyboard module be raised to an angle to conform to ergonomics to facilitate user operations and to alleviate fatigue in the user’s hands. The insulating film continuously extends on the inner wall of the through hole and on the second surface. An exhaust equipment member formed by this heat-resistant cast iron has an AC transformation point is 840\xb0 C.
