Abstract: A semiconductor device includes: a trench formed in a surface of a semiconductor substrate and extending lengthwise in a direction parallel to the surface; a body region adjoining the trench; a source region adjoining the trench above the body region; a drift region adjoining the trench below the body region; a field electrode in a lower part of the trench and separated from the substrate; and a gate electrode in an upper part of the trench and separated from the substrate and the field electrode. A first section of the field electrode is buried below the gate electrode in the trench. A second section of the field electrode transitions upward from the first section in a direction toward the surface. The separation between the second section and the gate electrode is greater than or equal to the separation between the first section and the gate electrode.

Abstract: A mounting system for mounting photovoltaic panels, which provides for a quick and easy assembly. The ground mount system for photovoltaic panels includes at least two vertical supports, wherein attached to each vertical support are a T plate connected to a vertical support, a post frame connected to the T plate, and a kicker brace connected between the vertical support and the post frame. The ground mount system may further include a first C-Purlin connected to a first end of the post frame, to a second C-Purlin connected to a second end of the post frame, a purlin tie connected between the first C-Purlin and the second C-Purlin. Panel clamps secure a photovoltaic panel assembly to the mounting system.

Abstract: A roller projection screen, including a projection screen material having a reflective front surface, onto which an image may be projected, and a back surface. The projection screen material is secured to a roller at an upper edge of the material and the projection screen material can be rolled in a spiral fashion in multiple layers around the roller. A buffer material is secured to the roller or to the back surface of the projection screen material so as to be adjacent the back surface and so as the be interposed between at least some of the multiple layers of the projection screen material when the projection screen material is rolled about the roller so as to inhibit ladder marks in the projection screen material.
