Title: Air-fuel ratio control device for multiple cylinder internal combustion engine
Inventor: OMORI SHOGO
IPC: F02D41/02
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To enlarge a lean operation area so as to improve fuel consumption and to reduce NOx by individually controlling the air-fuel ratio of mixture cylinder by cylinder according to an operating state, and setting the air-fuel ratio of all cylinders to a lean air-fuel ratio in a first operating state, and the air-fuel ratio of partial cylinders to a rich air-fuel ratio in a second operating state. SOLUTION: In case of providing NOx purifying catalysts 7a-7d for every exhaust passage 6a-6d, the injected fuel quantity from a fuel injection valve 5 is controlled cylinder by cylinder by an ECU 10 on the basis of the output of various sensors to control an air-fuel ratio. At this time, torque T required at that time is obtained from the air quantity per one intake stroke, and according to this torque T, one of the action modes of all cylinder lean control, 1/2 cylinder lean control and all cylinder rich control is selected. Switching control to a state of operating all cylinders at a lean air-fuel ratio and a state of operating only partial cylinders at a rich air-fuel ratio or a stoichiometric air-fuel ratio is then performed to suppress torque fluctuation at the time of switching the air-fuel ratio while improving fuel consumption.

Title: Gear pump
Inventor: MIHASHI SHINICHI
IPC: F04C13/00
Filed: 1990-11-22
Abstract: PURPOSE:To prevent any thermal deterioration due to seizure in bearing portions or residence of liquid to be transported by making a discharge pressure uniform with variation of gaps between the intermediate bearings and gears in the case of occurrence of a difference in discharge pressure between the gears. CONSTITUTION:A gear pump 1 for transporting high viscous fluid is used for transportation of high molecular melt such as polyester. A pair of fluid transportation passages are constituted of a space surrounded by an outer peripheral surface of teeth of gears 3-6, an inner circumferential surface of a case main body 7, and side surfaces of bearings 23-28. Fluid is sucked through a suction path 11 with rotation of the driving gears 3, 5, to be discharged from discharge paths 12, 13. If a difference in discharge pressure between the discharge paths 12, 13 occurs caused by a machining error of the gears 3-6 and a difference in pressure loss in a pipeline, intermediate bearings 25, 28 are moved in the axial direction due to the difference in pressure. Therefore, gaps between the intermediate bearings 25, 28 and the other pair of gears 5, 6 are different from each other so that the gap on a side where the discharge pressure is higher becomes large, and consequently, a leakage quantity is increased, thus making the discharge pressure uniform.

Title: Fly ash induration restraining agent and fly ash induration restraining method employing the same
Inventor: MURAOKA YOSHIMASA
IPC: C09K3/00
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To restrain the induration of fly ash, which is generated upon restraining powder dust, generated upon fly ash powder handling operation, by spraying water, by a method wherein fly ash induration restraining agent is formed of water, whose amount is within a specified range, and the balance of low-class monovalent alcohol. SOLUTION: 70-95wt.% of water and the balance of monovalent low class alcohol are added to 100 pts.wt. of fly ash. Methyl alcohol, ethyl alcohol, propyl alcohol, butyl alcohol and the like, for example, can be recommended as the monovalent low class alcohol. The alcohol has an effect of not only reducing the rate of water or indurating reaction generating substance but also reducing the hydrogenating reaction of calcium in fly ash by co-existing water and, as a result, alcohol makes hard to generate pozzolan reaction due to the generation of hardened substances. According to this method, the generation of dust can be prevented sufficiently and the induration of the fly ash can be restrained.
