Abstract: A cantilevered screwless hanger. The cantilevered screwless hanger includes an elongated member having a support assembly disposed on a first end thereof. In some embodiments, the elongated member includes a hanging device on a second end thereof. The support assembly includes a lower U-shaped member, a connecting member extending upwardly therefrom, and an upper U-shaped member connected to the connecting member. The lower U-shaped member is oriented opposite the upper U-shaped member, such that a first opening defined by the lower U-shaped member is oriented opposite a second opening defined by the upper U-shaped member. The support assembly is adapted to removably secure the cantilevered screwless hanger to an elongated structure comprising a square cross-section without the use of additional fasteners, such that the support structure is not damaged during installation of the cantilevered screwless hanger.

Abstract: A method for forming a self-aligned overlay mark is disclosed. First, a first region, a second region and a main feature which is disposed between the first region and the second region all disposed on the substrate are provided. The first region defines a first edge and the second region defines a second edge. Second, a cut mask layer is formed to respectively cover the first region and the second region to expose the main feature. Next, the cut mask layer is determined if it is self-aligned with the second edge or the first edge, and creates a self-aligned overlay mark. Later, a main feature etching step is carried out to transfer the main feature into the substrate when the cut mask layer is determined to be self-aligned with the second edge or the first edge.

Abstract: An electric arc furnace includes a substantially cylindrically configured melting vessel having an upper shell defining a top opening. A water-cooled roof assembly is supported by the upper shell and positioned over the top opening and can be removed from the top opening for permitting the charging of scrap into the melting vessel. The water-cooled roof assembly includes an annular configured, water-cooled outer roof panel defining a central opening. An annular configured, water-cooled inner roof panel is positioned within the central opening of the outer roof panel and is removably mounted on the outer roof panel. The inner roof panel includes a central opening that removably mounts a central refractory. At least one electrode is mounted in the central refractory and extends into the melting vessel.
