Described are roll-to-roll or reel-to-reel thermal or rapid thermal processing tools (reactors) are used to react a precursor layer on a continuous flexible workpiece. Variants of the reactors are described, including a reactor having multiple exhaust outlets connected to a process gap of the reactor between an entrance opening and an exit opening of the process gap; a reactor including multiple gas inlets and exhaust outlets connected to a process gap of the reactor between an entrance opening and an exit opening of the process gap; a reactor including multiple gas inlets and exhaust outlets connected to a process gap of the reactor between an entrance opening and an exit opening of the process gap; and a reactor including multiple gas inlets and exhaust outlets connected to a process gap of the reactor between an entrance opening and an exit opening of the process gap. Also described is an exhaust system that separates the Group VIA material vapors from other gaseous species for re-cycling or easy disposal and techniques and apparatus for efficient removal of moisture from the workpiece before processing precursor layer in the RTP tool.

Systems and methods for killing bed bugs and other insects utilizing steam to increase the temperature of an area beyond the bed bugs' and other insect's thermal death point. Steam created by a steam generator is directed into an area for a sufficient amount of time to ensure that the bed bugs and other insects die. Furthermore, the systems and methods may include a barrier that defines a thermal kill zone which prevents bed bugs and other insects from escaping during treatment. Injection members may be used to more precisely direct steam in specific areas within the thermal kill zone and / or in joints, cracks, or crevices where bed bugs and other insects may be located.

The invention discloses a synchronous excavation supporting system for a deep and large asymmetric pit in a soft soil area and an implementation method of the supporting system. The deep and large asymmetric pit consists of a deep area and a shallow area which are internally close to each other, the top elevation of an enclosure structure at the junction of the deep area and the shallow area is a substrate of the shallow area, the total pit is provided with a first horizontal support in a unified way, the deep area is additionally provided with a plurality of deep-area horizontal supports, a soil body platform used for balancing the horizontal transfer force of the deep-area horizontal supports is reserved at the junction of the interior of the shallow area and the deep area, and two sides of the soil body platform are sloped to the substrate of the shallow area, so that open excavation and bottom-up construction in the deep area and the shallow area can be synchronously carried out, the problem of imbalance of the internal force and the deformation of the pit caused by an asymmetric excavation mode due to function requirements is solved, and the asymmetric pit can be excavated in a safe, reliable, economic and environment-friendly mode; through the synchronous excavation of the deep area and the shallow area, the construction period can be effectively shortened, and the construction cost is reduced; moreover, the supporting system is definitely stressed, the horizontal force of each horizontal support additionally arranged in the deep area is reliably transferred, and the construction feasibility is high.

(Problem) To provide a source liquid supply apparatus that avoids leaving source liquid- and / or cleaning fluid-derived residues in the vicinity of the joint or connection region between the source liquid feed conduit and the source tank. (Solution) A flow-switching mechanism Vc is attached to the source tank 22 of a source liquid supply apparatus 20. This flow-switching mechanism Vc has a first port 33 that is connected to the discharge port conduit 24 of the source tank 22, a second port 34 that is connected to a feed conduit 16, and a third port 35 that is connected to an exhaust conduit 25. The first port 33 can be closed by a valve member 43 on a diaphragm 42 disposed within a common compartment 38 while communication is maintained between the second and third ports 34 and 35. A cleaning fluid source 55 and a purge gas source 57 are connected to the feed conduit 16. Purge gas and cleaning fluid fed into the feed conduit 16 are discharged from the second and third ports 34 and 35 through the exhaust conduit 25.

A device for aftertreatment of exhaust gas includes: a prechamber having an exhaust gas inlet; a main chamber; a mixing device, in which the exhaust is mixable with an additive; and an intermediate device, via which a partial exhaust gas flow is deliverable from the prechamber to the mixing device. The intermediate device has swirl elements configured to reverse the direction of swirl of swirled exhaust gas flow generated in the prechamber as the exhaust gas overflows into the interior of the intermediate device, and / or the prechamber is configured to impel a first partial exhaust gas flow in a direction of swirl, and the main chamber is configured to impel a second partial exhaust gas flow from the prechamber in a direction of swirl, the direction of swirl of the exhaust gas in the prechamber being opposed to the direction of swirl of the exhaust gas in the main chamber.
