The method comprises providing a cleaning solution at a predetermined temperature lower than room temperature and cleaning the etched target with the cleaning solution. The apparatus for cleaning semiconductor devices comprises a chuck on which a semiconductor substrate is mounted; a solution storage part for storing a cleaning solution; a solution supply part for supplying the semiconductor substrate with the cleaning solution; a heat exchange part for maintaining the cleaning solution at a temperature lower than room temperature; and a control part for controlling the chuck rotation for a predetermined time and the cleaning solution delivery from the heat exchange part to the semiconductor substrate via the solution supply part. Accordingly, the present invention provides a more precise lateral profile of an etched pattern from the etch by-product cleaning process.

Abstract: The present invention relates to a heating apparatus using thermal reaction of brown gas. After brown gas generated from a brown gas generator passes hexane liquid in a flame arrester, it is burnt in a brown gas burner located at a lower portion of a heating element. Heating members are installed in multi-stage inside a heating element body of a hollow form. The heating element body located at each stage includes vent holes and exhaust openings. A cover is disposed on the top of the heating element. The heating member located at the lower portion is heated by flame of the brown gas, and then also the heating member located at an upper portion is heated by flame of high temperature caused by the thermal reaction of the brown gas, which gradually heats the lower heating member. After all, the whole heating members are heated to emit a vast heat.

Abstract: Disclosed is a Brown gas mass production apparatus having a line style electrolytic cell in which an electrolytic cell case having an electrolyte distribution and discharging pipe mounted on the inside bottom surface thereof is coated with insulation material on the inner surface thereof, electrode units are disposed by two or three groups in a side-by-side arrangement in the electrolytic cell case, an electrolytic cell upper plate having gas outlet nipples mounted thereon is sealingly coupled to the top surface of the cell case to form a secured sealing between edges of the upper plate and the cell case.

Abstract: A fire extinguisher selectively operable either manually or automatically is disclosed. The fire extinguisher comprises a container (100), a body (200), a discharge nozzle (600), an operating rod assembly (300), and an operating lever (400). The container (100) contains an extinguishing medium (110) under a pressure. The body (200) is fitted to the upper end of the container (100) and has a passage for releasing the extinguishing medium (110) under a predetermined condition. The discharge nozzle (600) is fitted to one portion of the body (200) to communicate with the passage and discharges the extinguishing medium (110). The operating rod assembly (300) manually controls an opening of the passage by applying a predetermined external force or automatically controls an opening of the passage under a predetermined temperature condition e operating lever (400) is located at the other portion of the body (200) and applies the predetermined external force to the operating rod assembly (300).

Abstract: A brown gas combustion apparatus and heating system using the same is provided in which a brown gas generated from a brown gas generator flows into a water-tight flame arrester filled with hexane(C6H14) of hydrocarbon systems so as to mix the brown gas with a small amount of hexane gas, to thereby delay the combustion speed and fundamentally prevent flash-back or back-fire. The brown gas combustion apparatus includes a heating unit which is directly heated by a burner and radiates heat. The heating system includes the combustion apparatus installed upright therein, and is configured in that the high temperature water molecules scattered from the combustion apparatus absorb the infrared ray radiated from an infrared ray radiation member within the combustion chamber, and oscillate in an ultra high temperature by self-heating.

Abstract: An energy generating apparatus using the cyclic combustion of Brown gas is disclosed. The apparatus comprises a heat generating unit, an outer wall, a Brown gas generator, an open-shut valve and a burner. The heat generating unit is positioned on a base. The outer wall surrounds the heat generating unit so as to define a combustion chamber, is provided with a discharge hole at its upper portion, and radiates infrared rays. The Brown gas generator is used to generate Brown gas. The open-shut valve is positioned between supply pipes so as to block the Brown gas discharged from the Brown gas generator. The burner is used to heat the heat generating unit by burning Brown gas supplied through the open-shut valve and the supply pipes.

Abstract: The Brown gas heating furnace made of mineral stone maintains a desired temperature with a small amount of fuel. The brown gas heating furnace includes a hollow base, having burner mounting holes formed in a top wall of the base, and a door mounted at a front side of the base. The burners are centrally mounted in the burner mounting holes of the base, with branch ducts connecting each of the burners to a Brown gas supply duct. A heating section consisting of firebricks stacked together in a staggered fashion on the top wall of the base encloses the burner mounting holes, with a furnace section seated on the base and having a combustion chamber surrounding the heating section. The furnace section also has venting holes adapted to vent the combustion chamber to the atmosphere. The furnace section may include stacked blocks made of mineral stone, biotite, germanium, or jade, or may use hollow mineral stones.

Abstract: A scooter for children which includes a long footboard between two small end wheels and is controlled by an upright steering handle attached to the front wheel through a spring member for absorbing and reducing the impact generated from the front wheel so as to prevent a store of fatigue from accumulating, to maintain a fine figure thereof and lengthen the life thereof.

Abstract: A transmission device for farm tractors is disclosed. In the transmission device, a hollow travelling drive shaft and a PTO drive internal shaft are substituted for a typical hollow PTO drive shaft and travelling internal shaft, respectively. The transmission device also has a splined flange for directly transmitting the engine power from the flywheel to the PTO drive internal shaft. In a main change gear unit, a hub sleeve and a main gear shifting shaft are forged into a single structure. A super low-speed change gear unit is connected to a sub-change gear through two sets of shafts capable of allowing the super low-speed change gear unit to be independently operated from the sub-speed change gear unit. The transmission device is thus selectively operated without performing any super low-speed changing action.
