摘要:
An exhaust gas control apparatus includes a control device controlling a urea addition valve for adding urea from an upstream side of a NOx reduction catalyst. The control device obtains an ammonia adsorption amount distribution through the NOx reduction catalyst. When an ammonia adsorption amount in a predetermined part on a downstream side equals or exceeds a predetermined threshold, the control device controls the urea addition valve to stop the urea supply or reduce the amount thereof. The urea addition valve is controlled based on an adsorption amount distribution obtained from a model on which the catalyst is divided into cells such that an ammonia adsorption amount in a first cell positioned furthest upstream equals or exceeds a predetermined threshold close to a saturation adsorption amount and an ammonia adsorption amount in a second cell positioned downstream of the first cell reaches a predetermined target value smaller than the threshold.

An exhaust gas purification system is equipped with a burner in an exhaust passage upstream of an exhaust gas purification apparatus and having a burner combustion chamber in which flame is produced. When the temperature of the exhaust gas purification apparatus is raised, the burner produces flame that extends from the interior of the burner combustion chamber to the interior of the exhaust passage when the flow rate of the exhaust gas is not higher than a predetermined flow rate, and the burner causes the size of the flame to be smaller than when it is determined that the flow rate of the exhaust gas is not higher than the predetermined flow rate or to produce flame only in the interior of the burner combustion chamber when it is determined that the flow rate of exhaust gas is higher than the predetermined flow rate.

The present invention provides a non-aqueous electrolyte battery, etc. that can reduce the manufacturing cost of the battery, meet the need for increased battery capacity, and at the same time improve various battery characteristics, such as high-rate charge-discharge capability, high-temperature cycle performance, and storage performance.A porous layer (32) is disposed between a separator and a negative electrode (13). The porous layer has a non-aqueous electrolyte permeability higher than that in TD of the separator. An excess electrolyte is contained in at least a portion of an internal space of a battery case that is other than an electrode assembly, and the excess electrolyte and at least a portion of the porous layer are in contact with each other.

An image display unit having a back-side substrate on which a number of electron emission elements are arranged, and a front-side substrate which is opposed to a back-side substrate and has fluorescent patterns and light-shielding patterns arranged at positions corresponding to electron emission elements, wherein a marking area is provided at least two locations in an ineffective part of the inside of the front-side substrate, corresponding to alignment marks of a dry plate, and each marking area has three alignment marks. According to the present invention, it is unnecessary to change R, G, B masks whenever three color fluorescent patterns are exposed, and realignment between a mask and a substrate is unnecessary.
摘要:
An exhaust emission purification device comprises a sulfur component holding agent arranged on the exhaust path of an internal combustion engine for holding a sulfur component, a NOx holding agent arranged downstream of the sulfur component holding agent in the exhaust gas for holding NOx and the sulfur components when the air-fuel ratio of the exhaust gas flowing thereinto is lean, and a reducing agent adding unit for adding a reducing agent to the exhaust gas flowing into the NOx holding agent. The concentration of the sulfur component contained in the reducing agent added by the reducing agent adding unit is lower than the concentration of at least the sulfur component contained in the fuel supplied to the combustion chamber of the internal combustion engine. Thus, the sulfur poisoning of the exhaust emission purifier can be avoided while at the same time reducing the fuel consumption rate.

摘要:
An exhaust purification catalyst (11) for purifying NOx under a lean air-fuel ratio is arranged in exhaust passage of an internal combustion engine. As a catalyst carrier (50) of this exhaust purification catalyst (11), alumina, which has base points on the carrier surface, is used. The surface of the alumina is made to carry platinum (51) dispersed on it without forming a layer of a NOx absorbent able to absorb NOx. The air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (11) is temporarily switched from lean to rich before the entire surface of the platinum (51) suffers from oxygen poisoning.
摘要:
Left side panels and right side panel are produced in a left side panel production line and a right side panel production line, respectively By vertical lifters, each left side panel and each right side panel are lifted at the delivery stations and then transferred to runners at work transfer positions. The runner with the left side panel held thereon travels along a rail while the runner with the right side panel held thereon travels along a rail. Both runners are stopped at a standby position and then conveyed to a runner transfer position simultaneously. The runners with the left and right side panels held thereon, respectively, are loaded on the traverser and then conveyed to a drop lifter arranged above a main body assembly line. The left and right side panels are transferred to the drop lifter. The drop lifter then descends and feeds the left and right side panels simultaneously on opposite sides of a floor panel in the main body assembly line.
