Title: Waste water treatment agent
Inventor: UENO TSUTOMU
IPC: B01J20/30
Filed: 1988-05-16
Abstract: PURPOSE:To prepare a waste water treatment agent of a high performance in sludge disposal by adding a substance for supplying a sulfate or a halogenide compound to substances for supplying calcium oxide, silicon dioxide and aluminum oxide and by subjecting this mixture to a hydration treatment. CONSTITUTION:One or more substances selected from a group of materials, which can supply a sulfate compound, a halogenide one, a sulfide one or a hydroxide of alkali metal, are added to substances, which can supply calcium oxide, silicon dioxide and aluminum oxide, and they are crushed, mixed together and mixed further after adding water. A waste water treatment agent is prepared by subjecting this mixture to a hydration treatment such as a moist-air curing in a room temperature water at atmospheric or high pressure, a steam curing or a hot-water curing.

Title: Air-fuel ratio controller for internal combustion engine
Inventor: DODA HISAYO
IPC: F02D41/14
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To execute air-fuel ratio control in which an adsorbing material amount in a catalyst is appropriately taken into consideration. SOLUTION: A catalytic reaction model is used as means to estimate an adsorbing material amount in a catalyst 53. This catalytic reaction model takes into consideration the whole presence of the adsorptive reaction of an inflow gas component in the catalyst 53, oxidation-reduction reaction of the inflow gas component with an adsorbing material in the catalyst 53, the elimination reaction of the adsorbing material in the catalyst 53, and the unreacted part of the inflow gas component. The adsorbing material amount is estimated by adsorbing material amount estimating means 55 on the basis of the output of an air-fuel ratio sensor 54 using this catalytic reaction model.  When the estimated adsorbing material amount is within a predetermined range, a target air-fuel ratio is set according to the adsorbing material amount, and when the adsorbing material is without the predetermined range, the target air-fuel ratio is set according to an air amount in the cylinder of an internal combustion engine 51. Further, the output of a downstream sensor 57 is estimated by sensor output estimating means 58 using the same sensor reaction model as the catalytic reaction model so that the deterioration of the catalyst 53 is also estimated from the relation between the estimated output and the actual output.
