Abstract: PROBLEM TO BE SOLVED: To promote a thermal decomposition reaction and to change gas into the pollution-free and the resource by recovering gas treating aluminum residual ash and blowing this gas into high temp. recovering gas generated at the metal smelting and refining time. SOLUTION: The aluminum residual ash stored in a hopper 1 is discharged with a feeder 2 and charged into a rotary furnace 3. Water is poured into the rotary furnace 3 and aluminum carbide and aluminum nitride in the aluminum residual ash, are reacted with the water at 20-50 deg.C the temp. in the furnace, to generate hydrocarbon and ammonia gas. The generated ammonia gas is dissolved into the water added in the aluminum residual ash to raise pH in this water. Aluminum oxide covering the metallic aluminum contained in the residual ash is dissoved with the high pH water and the metallic aluminum is exposed and reacted with the water to generate hydrogen. This reaction has large calorific value and brings about rapid heat-up in the reaction system. The aluminum residual ash in the rotary furnace 3 is promoted in this reaction with the heat-up to vaporize un-reacted moisture.  The treated material 6 can be used for slag-making material in the steel-making.

Title: Inputting method of coordinate
Inventor: OIDE TAKAHIRO
IPC: G06F3/038
Filed: 1984-07-17
Abstract: PURPOSE:To obtain coordinate input having high operability and accuracy by increasing/decreasing the cursor moving distance in a unit time in accordance with the replacing information in a unit time which is inputted from an input device. CONSTITUTION:To move the cursor 22 from the current position 23 to an objective position 24, a mouse 26 is moved. At a position close to the position 24, the mouse 26 is rapidly moved to the objective position 24. When the cursor 22 reaches the position close to the position 24, the mouse 26 is slowly moved to make the cursor 22 coincide with the position 24 precisely, and finally the cursor 22 is moved up to the position 24. Since the moving speed of the mouse 26 is rapid in the initial stage and the replaced variable in the unit time is large, the moving distance of the cursor 22 is increased more than an input value, but the moving speed of the mouse 26 is dropped near the objective position 24 and the moving distance of the cursor 22 is decreased less than the input value because the moving distance in the unit time is low. Thus, the cursor 22 can be positioned on the position 24.
