摘要:
To provide an apparatus for evaluating the deterioration condition of a catalyst of an internal combustion engine that can improve the accuracy of an evaluation of the deterioration condition of a catalyst and can suppress a worsening of emissions. The apparatus forcedly sets the air/fuel ratio upstream of a catalyst provided in an exhaust system of an internal combustion engine at a rich condition or a lean condition on the basis of a detected value of a sub O2 sensor downstream of the catalyst in the internal combustion engine and evaluates the deterioration condition of the catalyst. The air/fuel ratio control is reversed so that the air/fuel ratio upstream of the catalyst becomes a lean condition or a rich condition when ‘egasum’ has reached a predetermined value Ga, ‘egasum’ being an integrated value of an admitted air volume (an integration count of the amount of exhaust gas passing through the catalyst) in the period after the sub O2 sensor outputs a detected value, which shows a rich condition or a lean condition, until the reversing of the output of the sub O2 sensor.

摘要:
The present invention provides a microsphere with a slow-release period from about two weeks to about four weeks following administration, to enable a higher content of a drug to be included, to suppress an initial burst of the drug, and to maintain an optimal, effective blood concentration during the slow-release period. In a microsphere containing a drug and polylactic acid/glycolic acid (PLGA) copolymer, the amount of PLGA copolymer per part by weight of the drug is from about 3 to about 10 parts by weight; the average particle size of the microsphere is from about 20 to about 50 μm; and (3) the PLGA copolymer has a weight-average molecular weight from about 10,000 to about 50,000 and a PLGA compositional ratio from about 75/25 to about 50/50. The microsphere promotes the production of various endogenous repair factors useful against various tissue disorders.

In fuse program circuits, fuse element FS is implemented using metal interconnect at third or higher layer of multilayer metal interconnect. In each fuse program circuit, program information and fuse select information are sequentially transferred using a scan flip-flops, and fuses are selectively and electrically blown one by one. The fuse program circuit provided with fuse elements that can be programmed even after packaging is implemented with low power consumption and a low occupation area.

In a hydraulic actuator control device, a changing tendency of responsiveness of a hydraulic actuator to changes in the oil control valve (OCV) drive duty of a virtual OCV is stored as model control characteristics. The ratio of an actual OCV dead zone width to a virtual OCV dead zone width is calculated as an OCV variation correction coefficient. A basic control amount is calculated based on a deviation between an operating amount and a target operating amount of the hydraulic actuator. An actual OCV in-dead-zone control amount is obtained by correcting a virtual OCV in-dead-zone control amount with the OCV variation correction coefficient, and an actual OCV out-of-dead-zone control amount is calculated based on a virtual OCV out-of-dead-zone control amount. The actual OCV control amount is the sum of the actual OCV in-dead-zone control amount and the actual OCV out-of-dead-zone control amount.
摘要:
A catalyst degradation determining method includes the steps of: controlling an upstream-of-catalyst air-fuel ratio occurring upstream of a first catalyst to an air-fuel ratio that is rich of a stoichiometric air-fuel ratio so that first and second catalysts store oxygen up to a maximum storage amount of oxygen. The method then includes the steps of controlling the upstream-of-catalyst air-fuel ratio to a first lean air-fuel ratio until an output of a downstream-of-first-catalyst sensor indicates a lean air-fuel ratio, and then to a second lean air-fuel ratio and that has a value that is determined in accordance with an oxidizing-reducing capability index value, until a time point when an output of a downstream-of-second-catalyst air-fuel ratio sensor indicates an air-fuel ratio that is lean.

An object of the present invention is to provide an amino acid-containing drink and a method for reducing the bitterness of amino acids. The bitterness of an amino acid can be reduced by adding ornithine to the amino acid. Further, an amino acid-containing composition with reduced bitterness can be prepared by having ornithine contained in the composition.
摘要:
During sulfur release control in an internal combustion engine, a rich period and a lean period are alternately repeated. The air-fuel ratio of exhaust gas is controlled toward a target air-fuel ratio (14.3) by adding fuel from a fuel adding valve in the rich period. An ECU determines whether the actual air-fuel ratio of exhaust gas detected by an air-fuel ratio sensor has reached a stoichiometric air-fuel ratio each time the rich period ends at which addition of fuel from the fuel adding valve is stopped. A counter counts the number of times the ECU has determined that the actual air-fuel ratio of exhaust gas has not reached the stoichiometric air-fuel ratio. When the value of the counter becomes greater than or equal to a permissible value, the ECU determines that there is an abnormality in the sulfur release control.

摘要:
A catalyst degradation determining apparatus determines whether a catalyst provided in an exhaust passage of an internal combustion engine has degraded. The apparatus includes a controller. The controller acquires a degradation index value that changes in accordance with a degree of degradation of the catalyst. The controller corrects the degradation index value acquired, based on a factor that affects the degradation index value, so that the degradation index value becomes equal to a post-normalization index value that is a degradation index value acquired when the factor is a predetermined value. The controller also determines whether the catalyst has degraded, based on a result of comparison regarding whether the post-normalization index value is greater than a catalyst degradation criterion value.
