Title: Anti-back fire structure of low nitrogen oxides burner
Inventor: NAHAKI KAZO
IPC: F23D14/08
Filed: 1993-07-21
Granted: 1997-12-29
Abstract: a fire receiving burner(2) having a slit shape fire receiving port(21,22) in side of a main fire port(11) of a flat shape main burner(1); a common suction port(22) sucking the mixed gas independently to the main burner and formed in the fire receiving burner(2); and a control part for preventing a back fire positioned in the upstream section from the fire receiving port and formed in the fire receiving burner(2); is disclosed. Thereby, it is possible to effect a stable combustion and to prevent a back fire in pre-loading combustion.

Title: Wet-etching method in semiconductor process
Inventor: PARK SANG-HOON
IPC: G03F7/30
Filed: 1993-07-27
Granted: 1997-05-08
Abstract: A wet etching method for manufacturing semiconductor elevating temperature by injecting pure water in lower temperature  in 5~25 deg. C than the temperature in which cold H3PO4 is heated to inducing exothermic reaction and the apparatus having a means suppling pure water to H3PO4 bath; an air control valve mounted to said pure water suppling means in position remote to said H3PO4 bath; and a pure water injection quantity control means connected to said air control valve are disclosed. Thereby, it is possible to prevent the corrosion or damage due to H3PO4 vapor and to control the suppling speed of pure water to uniform state.
