  • Patent number: 10952558
    Abstract: A drapery connector has an extrusion having an extrusion hollow; a pair of rails formed on the extrusion; a pair of extrusion sidewalls supporting the pair of rails; a pair of rollers engaging the extrusion; a roller frame retaining the axle; and a carriage line connecting the upper carriage to a successive upper carriage. The upper carriage is translationally mounted inside the extrusion in the extrusion hollow. The pair of rollers share a common axle, and the upper carriage has a pair of rollers with a common axle. The roller frame has a roller frame flat face oriented parallel to a wheel inside vertical surface. The upper carriage further has a roller frame. A pair of roller frame flat faces are formed on the roller frame. Each of the roller frame flat faces are closer to the wheel inside vertical surfaces than a thickness of a carriage line.

  • Publication number: 20150382442
    Abstract: This disclosure describes systems, methods, and apparatus for pulsed RF power delivery to a plasma load for plasma processing of a substrate. In order to maximize power delivery, a calibration phase using a dummy substrate or no substrate in the chamber, is used to ascertain a preferred fixed initial RF frequency for each pulse. This fixed initial RF frequency is then used at the start of each pulse during a processing phase, where a real substrate is used and processed in the chamber.

  • Publication number: 20060186783
    Abstract: Disclosed herein is a panel of a slim cathode ray tube constructed such that the deflection angle of an electron beam is 110 degrees or more. The slim cathode ray tube includes a tube part constituted by joining the panel and a funnel with each other. The panel includes a face part, a side wall disposed around the face part such that the side wall is bent toward the funnel, and a seal edge formed at the side wall, the panel being joined with the funnel at the seal edge. On the assumption that the thickness of the center of the face part is Tc, the thickness of the long side of the seal edge is Tx, the thickness of the short side of the seal edge is Ty, and the thickness of the diagonal part of the seal edge is Td, the panel is constructed such that the following inequalities are satisfied: 0.8?Tc/Ty?Tc/Tx?1.0?Tc/Td and Td<Tx<Ty, and the side wall has an outer skirt angle of 0.5 to 1.5 degrees.
