The present application provides a dispensing apparatus for processing an electronic component, comprising: a first track component and a second track component, a first flow-guiding component and a second flow-guiding component, the first flow-guiding component being arranged at the top of the first track component, the second flow-guiding component being arranged at the top of the second track component, the first flow-guiding component having at least one first gas inlet and at least one first gas outlet in communication with each other, the at least one first gas inlet being configured to be in communication with a clean gas source, the second flow-guiding component having at least one second gas inlet and at least one second gas outlet in communication with each other, the at least one second gas inlet being arranged facing the first gas outlet, and the at least one second gas outlet being configured to be in communication with a gas discharge motive power apparatus, so that clean gas can flow toward the at least one second gas inlet from the at least one first gas outlet, thereby forming a clean gas region above the electronic component to be processed, to avoid contamination with impurities during processing.

The invention is a table top filtration device designed to filter noxious fumes on or near the table. In one embodiment, the tables are manicure and pedicure tables.

The present invention provides a system for collecting tripper room fugitive dust of a power plant coal transfer facility, wherein the system includes an entrance dust collection module disposed at the entrance of a tripper room to block dust; a tripper car configured to move along a transfer conveyor disposed inside the tripper room and transfer fuel introduced through the entrance to silos; and a main dust collection module configured prevent spread of dust by removing dust in response to movement of the tripper car and adjusting the pressure at the point where dust is generated.

A ventilation system is disclosed comprising a main duct (101) connected to at least one motorized fan (105), and further connected to at least one workplace (Wa; Wb; Wc) via a local duct arrangement (102a; 102b; 102c). The local duct arrangement comprises an asymmetrical bend duct section (106). A first and a second pressure sensor (120,122) are arranged on different positions on the outside of the bend duct section and in communication with the interior thereof. The pressure sensors are configured to communicate with a control computer (200) configured to determine a pressure difference between the positions of the sensors and to control the speed of the fan. Further, a method of operating a ventilation system is disclosed and also an asymmetric bend duct section and the use thereof.

A substrate processing apparatus includes a first processing unit and a second processing unit placed in upper and lower two stages. Each processing unit has: a plurality of processing tanks arranged in series; a partition wall defining a conveyance space extending along an arrangement direction outside the plurality of processing tanks; a conveyance mechanism placed in the conveyance space and being configured to convey a substrate between the processing tanks along the arrangement direction; and an air guide duct provided to extend along the arrangement direction in the conveyance space. The air guide duct is connected with a fan filter unit. Each of the processing tanks is connected with an exhaust duct. An opening is formed in each of parts facing the processing tank in the air guide duct. The conveyance spaces of the first and second processing units are separated into upper and lower segments by the partition wall.

A cutting machine waste extraction apparatus is provided for a cutting machine that cuts a plate where the cutting machine waste extraction apparatus is supported adjacent a cutting area at a cutting table. The cutting machine produces waste at the cutting area during the cutting of the plate where the apparatus includes a ducting system having a first duct that receives the waste from the plate, and a second duct that receives the waste from the first duct. The first duct is movable along the length of the second duct and the second duct includes a lengthwise opening which is sealed by a flexible belt. The flexible belt is deformable from sealed contact with the second duct, adjacent a junction apparatus, where the junction apparatus provides a fluid connection between the first duct and the second duct.
