Title: Picture forming device
Inventor: ISHIKAWA TADASHI
IPC: G03G15/00
Filed: 1988-12-28
Abstract: PURPOSE:To minimize an increase in a chip area and to reduce costs by providing a chip with an input port for monitoring a power source voltage, periodically checking whether the voltage of the input port drops below a threshold level or not and moving to a low power consumption mode when the voltage drops. CONSTITUTION:The forming device has a controller 1 (chip), a power source voltage monitoring port 2, and a power source terminal 3. Here, a time constant when output voltages from voltage generating means 5 to 7 drop is set far lower than that when an output voltage from a power source device drops. The power source voltage monitoring port 2 is handled not as an interruption input but as merely an input port. Software periodically checks, and when a voltage drop is detected, the current operation is immediately shifted to the lower power consumption mode. Consequently, no dedicated interrupter, etc., for the shift is needed to minimize an increase in the chip area, thereby reducing costs.

Title: Cogeneration system
Inventor: OGURA YOSHIHIRO
IPC: F23C99/00
Filed: 1994-12-03
Abstract: PURPOSE: To provide a cogeneration waste recombustion system in which even if a burner is turned down, a combustion state is prevented from becoming unstable or producing carbon monoxide, and low NOx is ensured. CONSTITUTION: There are formed a primary waste passage 4 where a passage 3 for waste supplied from a gas turbine to a waste heat boiler is branched upstream a burner 2 and the waste and a fuel to the burner are directly mixed to form a primary flame, and a secondary waste passage 5 which joins the passage 4 downstream the burner 2 and makes contact with the primary flame. There is further provided means 6 for controlling a flow rate ratio of both passages 4, 5 in response to an increase and a decrease of the supply amount of the fuel to the burner 2.  Accordingly, upon the burner being turned down, the flow rate of the primary waste mixed with the fuel is also drawn so that there is eliminated the possibility of the amount of the mixing of the waste becoming excessive to secure stable combustion at all times, and also upon maximum combustion flame temperature is properly lowered to restrict the amount of production of NOx by controlling the flow rate ratio such that the amount of the primary waste is supplied in a slightly insufficient amount to ensure complete combustion with the secondary waste.

Title: Production of sintered ore
Inventor: FUJII NORIBUMI
IPC: C22B1/16
Filed: 1987-12-28
Abstract: PURPOSE:To produce sintered ore having god reducing ratio and reduced powdering by separating sintering raw material with Al2O3 content, beforehand mixing and pelletizing the low Al2O3 raw material, successively mixing together with the sintering raw material containing high Al2O3 raw material and sintering. CONSTITUTION:The sintering raw material is separated with the Al2O3 content and the low Al2XO3 raw material having <=1.8wt.% Al2XO3 is beforehand mixed and pelletized. Successively, this is mixed with the sintering raw material having >1.8% Al2O3 and supplied to the sintering operation. The low Al2O3 raw mate rial, which becomes large diameter size by pre-pelletizing, is charged into lower layer on pallet by grain segregation and reduced powdering is improved. On the other hand, the high Al2O2 raw material is charged on upper layer, and as the cooling speed is quickened, the reducing ratio and the reduced powdering are not deteriorated. By this method, the high Al2O3 raw material is used and the reduced powdering can be improved without deteriorating the reduction ratio.

Title: Liquid phosphoric acid
Inventor: YODA YUKIHIRO
IPC: C01B25/223
Filed: 1992-12-10
Abstract: PURPOSE:To obtain indrustrial liq. phosphoric acid for which the succeeding precipitation is suppressed and the corrosiveness is reduced by producing liq. phosphoric acid and a gypsum slurry by making the reaction of phosphate rock with sulfuric acid and specifying the P2O5 content and oxidation-reduction potential of the liq. phosphoric acid. CONSTITUTION:Phosphate rock is allowed to react with sulfuric acid to obtain aq. phosphoric acid and a gypsum slurry by a wet process. The P2O5 content of the liq. phosphoric acid is controlled to 40-65wt.% and the oxidation-reduction potential to 600-1250mV. The removal efficiency is decreased when the reaction time is too short. Meanwhile, when the reaction time is longer than necessary, arsenic sulfide is decomposed, and the removal efficiency is decreased. Accordingly, the reaction time is preferably controlled to 0.5 to 30min. The added hydrogen sulfide or soluble sulfide is present in the liq. phosphoric acid in the form of hydrogen sulfide, and hence the reaction is preferably carried out at several kg/cm<2> to prevent the liberation of hydrogen sulfide.
