    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.

    摘要： A positioning apparatus for a liquid level sensor includes a liquid level sensor support, such as a generally horizontal platform, having an aperture for receiving at least a portion of the liquid level sensor. An arm extends from the support and has an aperture for receiving a liquid outlet tube extending from an outlet of a liquid pass-through device. A hollow socket is spaced apart from the arm and removably attachable to the outlet of the liquid pass-through device. The apparatus maintains the relative position and orientation of the liquid level sensor to the liquid outlet tube extending from the outlet of the liquid pass-through device.

    摘要： An in-line heater having a heating vessel, defined at least in part by a wall, through which fluid to be heated flows. The wall of the vessel has at least one port formed therein. A fitting, having a body defining a pass-through passageway, is attachable to the port. An end of the body of the fitting has a groove or a ring which mates with a corresponding ring or groove of the port to form a liquid seal between the end of the fitting and the wall of the heating vessel.

    摘要： The present invention is directed to a filter housing with a removable filter assembly having an elongated shell assembly, a removable head assembly, and a removable filter assembly. The shell assembly has an inlet section, an outlet section, and a filter assembly opening. The removable filter cartridge includes a top tube sheet, a bottom tube sheet and a plurality of filter cartridges. The filter cartridges provide the only fluid passage through the bottom tube sheet, which otherwise sealing engages a ring assembly within the shell assembly proximate to the outlet section.

    摘要： A heater for solvents and flammable fluids having a heater core, an hermetically sealed electrical chamber, and a housing cap. The heater core includes a process fluid tube, a heating element, and a thermal well, all enclosed within a cast aluminum billet. The heating element, the process fluid tube, and the thermal well are all thermally associated with one another. The electrical chamber is embedded in a first end of the cast aluminum billet. Electrodes from the heating element extend into the electrical chamber and are connected to electrical wires. The electrical chamber is filled with a non-conducting epoxy that covers and encloses the electrical connections. The housing cap is sealingly disposed on the first end of the cast aluminum billet covering the electrical chamber.
