A refractory vessel that can be used as a gasifier for black liquor includes a generally cylindrical metal shell having a dome. A refractory shell has a cylindrical portion spaced inwardly from the metal shell and a dome portion that is spaced inwardly from the metal dome. The refractory shell is sized to provide an expansion gap between the liner and the metal shell. A selectively crushable liner is positioned in the gap. The liner has a predetermined yield stress that will provide controlled resistance to expansion of the refractory shell.

A baking apparatus for manufacturing a semiconductor device remarkably enhances the uniformity of the CD (Critical Dimension) of a wafer by creating a uniform temperature distribution. The apparatus includes a processing having an open upper part, a hot plate disposed in the chamber and on which a wafer is to be mounted, a cover covering the upper part of the chamber; and a thin film made of material having a low emissivity extending over the inner surface of the cover. The inventive structure prevents the emission of heat to the outside so that the temperature within the processing chamber can be rapidly stabilized.

A tiltable rotary furnace system includes a tiltable rotary furnace which rotates about a central axis and pivots around a general horizontal axis similar to a typical tiltable rotary furnace. The tiltable rotary furnace and the rotating and pivoting mechanisms are mounted on a rotating platform. The rotating platform allows the furnace to be positioned with respect to other elements of the system rather than having to position the other elements of the system with respect to a stationary tiltable rotary furnace.

An apparatus for dense chip packaging using heat pipes and thermoelectric coolers is provided. The apparatus includes an evaporator region, a condenser region, and a capillary region. The evaporator region includes one or more hot point elements used to transfer heat from a heat source to a transport fluid. The transport fluid changes state to a vapor when heat is applied to the transport fluid. The vapor travels to the condenser region via vapor channels and is condensed to a fluid once again by transferring heat from the vapor to a heat sink. The condensed fluid is then returned to the evaporator region by way of capillary forces and capillaries formed in a capillary structure. The capillaries formed in the capillary structure have a tree-like or fractal geometry. The apparatus may further include a flexible region that allows the apparatus to be bent around corners and edges.

Device to take in fumes and cool the roof (10) of electric furnaces. The device has a central aperture (11) into which an electrode can be inserted and a peripheral aperture (12) to take in and discharge the fumes. The device also has a first cooling system (13) for a central zone surrounding, and cooperating with, the central aperture (11), and a second system (15) to take in and convey the fumes. The first cooling system (13) includes a circular cyclone chamber (18) having a plurality of turns (19) able to cool the zone surrounding the central aperture (11).

A blanket of fibrous building insulation is provided, for in situ cutting to correspond to spacings between studs or like building members between which the insulation is to be applied. The blanket includes a layer of fibrous insulation material and a facing material adhered thereto. An adhesive provides the adhesion between the two layers. Perforations in the facing material provide openings allowing some of the adhesive to bleed into the perforations to be visible from the opposite side whereby a plurality of perforations provide guidelines for cutting the blanket to desired sizes for installation between structural building members.

This invention is directed to a method for carrying out combustion in a furnace having porous walls with a large surface area comprising providing a combustion zone containing an atmosphere of furnace gases. A low velocity oxidant stream is injected through at least one oxidant injection side of the porous walls into the combustion zone and mixing furnace gases with the oxidant stream in a mixing zone within the combustion zone to produce an oxidant mixture. A fuel stream is injected through at least one fuel injection side adjacent to the oxidant injection side in the combustion zone. The oxidant mixture is mixed with the fuel stream to create a fuel-oxidant mixture.

An energy conversion system which comprises a solid fuel fed combustor system having a first chamber portion with an inlet feed for feeding a metered amount of a solid fuel thereto, a first burner stage having a first traveling conveyor firebelt, a metered amount of air introduced in progressively increasing proportions along the length of the first traveling conveyor. A second burner stage having a second traveling conveyor firebelt with air introduced in a progressively decreasing amount along the length of said second traveling conveyor firebelt and a controller for controlling air introduced to the system. The chamber has a sloped common roof section common to the burner stages and is made of radiative energy reflective fire brick and angled to reflect radiative energy generated from fuel traveling on the traveling conveyor firebelts and directing the radiative energy on fuel traveling on the first firebelt. The air introduced is controlled in amounts so as to automatically minimize excess air to the firebelt conveyors to minimize the quantity of carbon monoxide and nitrogen oxides and other pollutants.

In a substrate processing apparatus, processing units are stacked in a multistage manner around a transport robot arranged at the center of a processing area for forming a processing part. In a second hierarchy, rotary coating units are arranged through an indexer and a transport robot. In a fourth hierarchy located above the second hierarchy, rotary developing units are stacked above the rotary coating units respectively. Multistage thermal processing units and an edge exposure unit are horizontally arranged above an interface mechanism part. Thus, a substrate processing apparatus capable of reducing the area for setting the same is provided.

A portable kiln has a set of wheels, a handle and a platform base. The wheels and the handle are attached on a first side of the kiln so that the kiln can be tilted and rolled on the wheels using the handle. The platform base provides a spaced distance between the wheels and the floor when the kiln is sitting upright in an operational position. The kiln may also include a metal outer shell wrapped about an oven portion. The outer shell has a shell sidewall radially spaced from the oven portion sidewall, which forms an annular air channel between the outer shell sidewall and the oven portion. The outer shell has a C-shaped cross-section and it has upper and lower vent openings for the air channel. A hinge assembly allows a lid of the kiln to rest in an open position.
