Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To maintain good exhaust gas purifying efficiency of a three-way catalyst on a second cylinder group side even in a condition in which synchronization of phases of air-fuel ratio fluctuation of two cylinder groups is required. SOLUTION: In this control device, a measuring means 31 measures the rich time and the lean time of fluctuation of the air-fuel ratio of a second cylinder group 22 on the basis of output of a second air-fuel ratio detecting means 26 when synchronization of phases of air-fuel ratio fluctuation of two cylinder groups 21, 22 is required. A calculating means 32 calculates a correction value so that the ratio of the measured rich time to lean time may coincide with a target value, and a calculating means 33 calculates a value obtained by correcting a first air-fuel ratio feedback correction factor α1 by the correction value as a second air-fuel ratio feedback correction factor α2S. A control means 34 feedback-controls the air-fuel ratio of the second cylinder group 22 by using the calculated second air-fuel ratio feedback correction factor α2S.

Title: Method for evaluating capacity of hydrogen storing alloy electrode
Inventor: SUGANO KENICHI
IPC: G01N27/26
Filed: 1987-06-26
Abstract: PURPOSE:To rapidly evaluate the charge and discharge capacities of a H2 storing alloy electrode, based on the reaction resistance value given to the occlusion and release of H2 with the electrolysis of the electrode generated when said electrode is immersed in an aqueous alkali solution. CONSTITUTION:A H2 storing electrode 4 and a reference electrode 5 are immersed in an aqueous KOH solution 2 so as to be positioned on both sides of an opposed electrode 3 and a constant current is generated from a current generator 6 and reaction resistance Rf is analyzed from the change in the potential of the electrode 4 by an analyzer 7 and displayed on a display device 8. Since Rf reduces to a H2 storage limit (capacity itself), when the min. value is calculated, the charge and discharge capacities of the electrode 4 can be evaluated with good accuracy. The electrode 4 is polarized at charge DELTAQ and consumed at the reaction resistance Rf. When a Faraday current (i) and overvoltage eta are eta=iRf, eta=eta0exp(-t/CRRf) (wherein eta0 is overvoltage immediately after a short constant current pulse is applied to the electrode) is formed. Further, the capacity of the interface of the electrode and a liquid is Cd=DELTAQ/eta0. When Cd is determined, a eta-t curve is analyzed to calculate Rf.

Abstract: PURPOSE:To prevent evaporation of the low-molecular component of a liquid crystal material and resin material and to develop intended characteristics with good reproducibility by sticking a sheet-like material which does not completely cover the liquid crystal material or a liquid crystal mixture onto this material or mixture and executing vacuum injection. CONSTITUTION:An empty cell is formed by fixing substrates 110, 111 with a sealing material 119. The liquid crystal material or the mixture (liquid crystal mixture) 202 composed of the liquid crystal material and an uncured resin is placed on an injection port 201 so as not to come into contact therewith and the sheet-like material 203 is placed thereon to decrease the area where the liquid crystal material or liquid crystal material mixture comes into contact with vacuum. The flowability of the liquid crystal material or the liquid crystal mixture 202 is increased by heating after vacuum evacuation. As a result, the liquid crystal material or the liquid crystal mixture moves together with the sheet-like material 203 on the inclined substrate 110 toward the injection port 201 side and comes into contact with the injection port 101. The liquid crystal material or the liquid crystal mixture 202 is thereafter injected into the cell when a positive pressure is generated at the circumference.
