Title: Molten iron direct manufacture and device
Inventor: ANTOWANU BUEINERU
IPC: C21B13/00
Filed: 1982-12-03
Abstract: A process and apparatus are presented for the direct production of molten iron from iron oxide ores in a metallurgical vessel. The process and apparatus involve decarbonization by oxygen blowing of an existing iron melt which has a carbon content above 1% and is covered with a slag layer. Heat is produced and the slag is oxidized and increased by foam formation. The thickness of the slag layer is continuously monitored, and overfoaming is prevented by directing into the melt an inert gas stream via charging units in the bottom of the vessel to counteract the formation of foam. Pulverized ore and carbon in an inert carrier gas are introduced into the slag foam through charging units in the vessel walls above the metal level. Blowing of oxygen and the injection of inert gas are regulated so that the slag level is essentially maintained at a fixed maximum height.

Abstract: PURPOSE:To make grating recess surfaces smooth by using gas, produced by mixing Ar with CHF3, as etching gas, and forming a grating pattern of photoresist on the surface of a quartz substrate and etching the substrate with an ion beam.

Title: Combustion apparatus
Inventor: SUGAWARA TATSUYA
IPC: F23D14/08
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To reduce NOx emission by a method wherein during operation of first and second burners, the flames of the second burners serve as pilot flames for the first burners to attain a stable excess-air combustion without a hindrance to flame stabilizing effect in the excess-air combustion. SOLUTION: Burners 1a and 1b are alternately, adjacently arranged so that flames 8a of the burners 1a always exist on both sides of flames 8b of the second burners 1b. As the flame 8b of the burner 1b is formed by excess-air combustion, it is poor in stability by itself. The stable flames 8a of the burners 1a are arranged on both sides of the flames 8b and serve as pilot frames. As the lean fuel gas with excess air is stably burned by the flames 8a produced by burning of rich fuel gas, the temperature of the flames 8b is kept low by the cooling effect of the excess air, resulting in a reduction of NOx emission.

Title: Ink-jet recorder
Inventor: UCHIKATA YOSHIRO
IPC: B41J2/51
Filed: 1992-07-17
Abstract: PURPOSE:To prevent the displacement (an inclination) of the position of storage by inclining and disposing the nozzle of a recording head in a fixed quantity and changing the discharge timing of the recording head in response to recording speed or recording resolution. CONSTITUTION:Ink is discharged in discharge time difference ta-1=nozzle inclination dXt cycle/R while a carrier 1 is carried in speed R/discharge period t cycle in the direction X1, thus offsetting the inclination of a nozzle and the discharge time difference of the nozzle, then realizing recording, in which there is no displacement. When recording speed is doubled without changing resolution R as draft recording, the period of discharge is set in t cycle/2, and ink is discharged in ta-1=dXt cycle/2R while the carrier 1 is carried at speed 2R/t cycle in the direction of X1, thus offsetting the inclination (d) of the nozzle and the discharge time difference ta-1 of the nozzle, then realizing recording, in which there is no displacement. Accordingly, the timing of discharge is altered in response to recording speed and recording resolution, thus attaining recording, in which displacement is not generated due to the discharge time difference of the nozzle.
