Abstract: According to an embodiment, a method for installing a vapor seal assembly to pass at least one continuous wire through an aperture defined by a bulkhead is provided. The method includes providing a split shell having a threaded, hollow cylindrical extension, providing a split annular gasket, assembling the split shell and the split gasket around the wire, placing the gasket onto the cylindrical extension, and passing the cylindrical extension through the aperture in the bulkhead. The method further includes providing an insert that defines at least one elongated channel for receiving the wire, pressing the wire into the channel, sliding the insert into the cylindrical extension of the shell, assembling a split retainer and a split nut around the wire, engaging the split nut into the retainer, and threading the split nut onto the cylindrical extension.

Abstract: The invented apparatus is a relatively small-volumed chamber useful for processing a substrate. The apparatus includes a reference member with a substantially flat surface. The apparatus also includes a stage member with a surface that supports the substrate, and that has a gas bearing surrounding this support surface. Gas flows through the bearing are regulated to generate a seal of the substrate from ambient gases upon bringing the gas bearing close to the reference member's flat surface. The seal generated by the gas bearing can also be used to contain process gas in proximity to the substrate. Such process gas can be introduced into and exhausted from the chamber through an inlet and outlet, respectively, defined in the reference member. The apparatus can include a window fixed in the reference member. Patterned light or a particle beam can be directed through the window to the contained substrate to cause selective reactions to occur thereon.

Abstract: A three-way finger joint for joining three structural elements comprising at least five layers of interlocking fingers and slots. The top and bottom finger elements on one member are identical to each other and to the corresponding elements on the other members. The middle layers comprise a fully interlocking arrangement of fingers and slots, in which a long finger on each member mates with corresponding slots on the other two. The long finger may be formed or cut off to be flush with the joint surface. The joint thus formed is strong, rigid and aesthetically pleasing.
