Abstract: The present invention pertains to a more efficient system and method for forming rectifying junction contacts in PIN alloy-semiconductor devices using photoelectrical and chemical etching. The present invention provides a means of creating rectifying junction contacts on alloy-semiconductor devices such as CdTe and CdZnTe, among others. In addition, the present invention also provides a simple and low cost method for revealing wafer surface morphology of alloy-semiconductors, thus providing an efficient and effective means for selecting single grain semiconductor substrates. Further, the present invention provides radiation detectors employing such alloy-semiconductor devices having improved rectifying junctions as the detector element.

Abstract: A fluid collection bag and drain assembly comprises: a container having an interior chamber for collecting fluid. Mounted to the container is a compressible, resilient outlet tube having a passage in fluid communication with the interior chamber of the container. A housing surrounds the outlet tube, and the discharge end of the outlet tube is disposed to discharge fluid through the open lower end of the housing. A lever is pivotably mounted to the housing. A closure member extending from the lever is operative to clamp off the outlet tube when the lever is in a closed position and to permit the outlet tube to open when the lever is in an open position. A cover member is pivotably mounted to the housing and is normally operative to close the open lower end of the housing. The cover member is operatively linked to the lever such that when the lever is opened, the cover member is opened to uncover the open lower end of the housing concurrent with the outlet tube being permitted to open.
