摘要： A cylinder valve assembly includes an actual on-off control subsystem. An intermediate chamber extends between a probe chamber and proximal chamber of the valve body along a main axis. A control port extends radially of the main axis. A valve pin is received by the intermediate chamber and movable between closed and open positions. A control plug is received by the control port and actuatable between on and off positions. Fluid communication between the proximal and probe chambers through the valve body is enabled when the valve pin is in the open position and the control plug is in the on position. Contrastingly, such fluid communication is prevented if either the valve pin is in the closed position or the control plug is in the off position. The control plug is preferably located in radial alignment along the main axis with at least a portion of the valve pin.

摘要： A visual position indicator for a valve includes a knob and inner and outer sleeves. The knob is rotatably mounted on the valve and is attached to a stem operating to open and close the valve. The inner sleeve connected on the valve includes a first colored band and an outer thread portion. The outer sleeve engaged with the knob includes a second colored band and an inner thread portion. The outer and inner thread portions are engaged with each other. The first and second colored bands respectively have a color different to each other. While the valve is closed, the outer sleeve fully conceals the inner sleeve to cause the second colored band to be visible. While the valve is open, the outer sleeve is fully concealed by the knob to cause the first colored band to be visible.

摘要： A circuit structure includes a substrate, a nucleation layer of undoped aluminum nitride, a graded buffer layer comprising aluminum, gallium, nitrogen, one of silicon and oxygen, and a p-type conductivity dopant, a ungraded buffer layer comprising gallium, nitrogen, one of silicon and oxygen, and a p-type conductivity dopant without aluminum, and a bulk layer of undoped gallium nitride over the ungraded buffer layer. The various dopants in the graded buffer layer and the ungraded buffer layer increases resistivity and results in layers having an intrinsically balanced conductivity.
