  • Patent number: 11867364
    Abstract: Light emitting diode (LED) light tubes having rotatable end cap assemblies are described. The LED light tubes include a hollow tube and a circuit board with LED chips thereon. The end cap assemblies are provided on either end of the tube. Each end cap assembly includes a socket cap, a plug having a plug body and at least one connector, and an end cap body, one end of which engages one of the ends of the hollow tube. A cam locking mount that is positioned within the plug body and on the opposite side has projections to be positioned in the bore of the end cap body. A rotation cam is seated in the cam locking mount and provides for controlled rotation of the LED tube relative to the end caps. Methods of installing the LED light tubes in new installations and retrofit installations and for use in sign assemblies are also described.

  • Publication number: 20220316063
    Abstract: RPCVD apparatus for forming a film is disclosed including a showerhead having at least one gas chamber, one or more plasma inlets to deliver plasma from one or more plasma generators into a reaction chamber; and a plurality of gas inlets to deliver gas from at least one gas chamber into the reaction chamber. At least one of the plasma inlets is located at a position that is between a central region and an outer region of the showerhead and off-centre from an axis of rotation. The plasma generators generate plasma in line of sight of the susceptor and the plasma inlets have openings that are larger than openings of the gas inlets. The gas inlets are configured such that a combination of all of the spatial distributions of gas from the gas inlets provides a uniform distribution of gas density on the surface of a susceptor between a central region and an outer region of the susceptor, for a full rotation of the susceptor.

  • Patent number: 11081618
    Abstract: Methods for fabricating semiconductor devices incorporating an activated p-(Al,In)GaN layer include exposing a p-(Al,In)GaN layer to a gaseous composition of H2 and/or NH3 under conditions that would otherwise passivate the p-(Al,In)GaN layer. The methods do not include subjecting the p-(Al,In)GaN layer to a separate activation step in a low hydrogen or hydrogen-free environment. The methods can be used to fabricate buried activated n/p-(Al,In)GaN tunnel junctions, which can be incorporated into electronic devices.
