Abstract: PURPOSE:To provide a burner to which a high temperature heat source having less soot and which is freed from backfire by a method wherein incomplete combustion gas in a combustion cylinder is gasified and injected in flowing-around combustion gas and reburnt by means of the backfire heat of the combustion gas. CONSTITUTION:Fuel (f) is disturbed and diffused by means of pressurized air (a) injected through gasifying holes 12, 12... in a first combustion cylinder 13 and brought into a misty state. Therefore, by igniting and burning the fuel by means of an ignition device, the fuel produces incomplete combustion gas g1, which is expanded most thereof flows in a second combustion cylinder 14. Since the rear part of the interior of an outer combustion cylinder body 1 produces a pressure reduced part by means of the pressurized air (a) fed through a blast duct 4, combustion gas g2 discharged from the second combustion cylinder 14 reversely flows within the outer combustion cylinder body toward the pressure reduced part along the outer periphery of an inner combustion cylinder body 16. The incomplete combustion gas 91 is injected through gas injection holes 10, 10... and mixed in the reverse flowing combustion gas g2 and burnt by means of the backfire heat of the gas g2 to produce combustion gas g3, which is carried on the pressurized air (a) through a blast duct 4 and flows to a front. A part thereof flows through a gas flow gap 15 to the second combustion cylinder 14. As flowing-around is repeated, high temperature complete combustion gas (g) is injected outwardly through a gas discharge cylinder 7.

IPC: H01L21/56
Filed: 1992-07-06
Abstract: PURPOSE:To seal only a tape carrier where semiconductor elements are mounted on a substrate by discharging fog-state resin on the semiconductor elements without applying any pressure on the tape carrier, a printed board or the substrate such as a lead frame and without masking, and performing resin sealing. CONSTITUTION:A tape carrier 4 is provided so that the tape carrier comes to close contact with the lower part of a mask 2.
