The present invention is a material forming apparatus that includes a piece of material that is a piece of laminated wood, a cover sheet made of plastic material, a flexible bed, a plurality of bed arms and a plurality of drive gears. The material forming apparatus also includes a numerical digital display, a plurality of roller clamps, one or more cranks with a grasping knob and a plurality of pivoting arms that are rotated by rotation of the drive gears and move the bed arms to force the flexible bed and the piece of material into a desired arc radius.

Disclosed is a housing for electronic/electrical that includes an inner panel and an outer panel, a strip of metal plate, and a strip of shape memory material. The inner panel and the outer panel are disposed parallel to each other at regular intervals to define an internal space. The strip of metal plate extends from an inner surface of the outer panel. The strip of shape memory material extends from an inner surface of the inner panel and is attached or detached to/from the metal plate on the outer panel while changing into an original straight shape or a bent shape according to a temperature variation. Here, when the temperature increase beyond a first transition temperature, the shape memory material straightens to form a heat transfer path. At a low temperature environment, the shape memory material bends and is separated from the metal plate to interrupt the heat transfer path.
