摘要： An illuminating and viewing unit for illuminating the interior of a vessel with source radiation and observing the vessel interior comprises a housing including a front wall facing the vessel interior. The front wall is of a material that does not transmit the source radiation, and includes one or more illumination ports individually fused into the front wall that transmit the source radiation to the vessel interior. A detection port is also individually fused into the front wall for transmitting detectable radiation along a detection path from the vessel interior to a radiation detector mounted in the housing. The optical isolation of the illumination and detection ports in the front wall prevents unwanted internal reflection of source radiation into the detection path, and allows for independent selection of port materials and configurations, while maintaining a hermetic seal between the housing and the internal contents of the vessel.

摘要： A view port of chemical vapor deposition apparatus for manufacturing semiconductor devices prevents heat loss in a chamber during a plasma deposition process. The view port includes a bracket protruding at the circumference of an opening in an electrode serving as a wall of a chamber of the apparatus, a transparent window pressed by the bracket against the wall via an O-ring, a pivoting cap for capping an opening in the bracket aligned with the window, and heat-insulative material and/or a heating element integral with the cap so as to be positioned close to the window when the cap is closed. The heating element can be a resistive heating wire or a warm air duct formed by a hose or the like. During the deposition process, the temperature of the window is maintained, thereby minimizing the tendency of polymer to adhere to the window.

摘要： A tubular stroboscope is interposed in the line of sight between a viewing glass and a process to be viewed in a chamber. The stroboscope is rotated about a central axis transverse to the line of sight and has a pair of diametrically opposed slots parallel to said axis, one slot being substantially wider than the opposite slot. The stroboscope is preferably driven by a jet of inert gas acting on a drive wheel inside the chamber, aspiration means being provided for dust removal.

摘要： A light pipe unit for supplying illumination to the interior of a vessel that has an attachment means for connection to the vessel. The light pipe unit is constructed of a metallic housing having an elongated fiber optic rod contained therein. At the bottom portions of the rod and housing, that is the portions extending into the vessel, is a glass laminate. The glass laminate covering forms a substantially corrosion-proof seal across the entire distal or lower portion of the unit.

摘要： A housing has an interior provided with two axially spaced and aligned openings, and is connectable in sealing relationship with a wall of the pressure vessel, so that one of the openings is in registry with a viewing port provided in this wall. A spherical, cylindrical or conical body having a bore is sealingly accommodated in the interior of the housing and can be turned to and from a position in which its bore registers with the openings and, hence, with the port. Sight glasses, lenses or the like are sealingly mounted in the bore and permit viewing of the interior of the pressure vessel when the body is in the position in which the bore registers with the openings.

摘要： A sight glass apparatus for viewing the interior of a pressurised vessel, chamber or a pipe conveying fluid under pressure is described. The sight glass apparatus comprises a sight glass assembly mounted over an opening into the vessel, chamber or pipe, the sight glass assembly comprising a sight glass adjacent the opening which provides a window to the inside of the vessel, chamber or pipe, and a containment vessel mounted behind and/or around the sight glass assembly for containing fluid exiting the opening in the pipe in the event that the sight glass assembly fails. In this way, even if the sight glass assembly fails, the pressurised fluid within the pressurised vessel, chamber or pipe is safely contained. In addition, a secondary sight glass can be provided behind the first, with a liquid or gel, or minimal gap, between the primary and secondary glasses to reduce the likelihood of a failure in the first sight glass triggering failure of the second sight glass, and/or a valve can be provided to automatically isolate the pressure system upon a sight glass failure.
