摘要:
A process for etching the surfaces of semiconductor substrates utilizes a texturing tank which introduces a process fluid through a circulating system. The process fluid is heated to a desired temperature and maintained at a desired concentration prior to entering a processing area where laminar flow is produced to more quickly and uniformly roughen the surface of semiconductor substrates. The texturing tank permits removal of bubbles and eliminates temperature stratification in the processing area.

A separator including a conical member having a base; a substantially cylindrical member extending from the base; a separator inlet for introducing liquid to be separated into the conical member in a substantially tangential direction with respect to a sidewall of the conical member; a heavy phase outlet communicated with an apex portion of the conical member; and a light phase outlet communicated with the cylindrical member.

A catalyst for hydrotreating, especially hydrodesulfurization, of residua and heavy crudes is prepared by synthesizing the support from titanium and boehmite, to form either a titanium/alumina support (TiO2/Al2O3) or a titanium-alumina support (TiO2—Al2O3) that is thereafter provided with at least one hydrogenating metal from group VIB in oxide form and a promoter from group VIII also in oxide form. The (TiO2/Al2O3) support is prepared from boehmite, which is peptized by using an inorganic acid, then extruded, calcined and impregnated with a solution containing titanium, while the (TiO2—Al2O3) support is prepared by admixing boehmite with a titanium-containing solution, peptized using an inorganic acid, extruded and calcined to obtain the titanium-alumina support.

摘要:
A fitting for use in fusion welding mating thermoplastic components includes a weld bead chamber to capture and conceal a bead formed as a result of the fusion weld. The weld bead chamber integrates the bead into the fitting so that the joined parts have a finished look without mechanical polishing or grinding of the completed piece. A stop ledge included in the weld bead chamber prevents over insertion of a pipe or other component into the fitting. A view window in the fitting permits inspection of the finished bead.
摘要:
A system and method are provided for reducing DI water consumption by delivering the DI water at an elevated processing temperature when demanded. The DI water is passed through a heater for heating the DI water to a processing temperature in a single pass. The DI water is circulated through a recirculation loop, including the heater, until demanded. The DI water is monitored for contaminants and bubbles or voids. Detected contaminants or voids are discharged through vents of the system. Turbulence or biocides can be introduced into the recirculated DI water for inhibiting biological contamination.
