摘要:
An apparatus for efficiently purifying NOx in the exhaust gas or soluble organic substance in the exhaust gas from a diesel engine. A plurality of purification units are arranged in a housing, each of which is composed of a catalytic layer for reducing NOx and a cooling core for cooling the exhaust gas admitted through the catalytic layer. The multi-staged purification units are so constructed to admit the exhaust gas to flow therethrough. The catalytic layer in the form of a porous carrier such as a honeycomb structure carries catalytic components. Upon purifying soluble organic substance in the exhaust gas from a diesel engine, the catalytic components carried on the catalytic layer serve to efficiently purify such substance, as well as inhibiting the reaction to form sulfate.
摘要:
Hydrogen gas from a hydrogen generator which creates hydrogen gas by the electrolysis of water or water vapor is supplied at the entrance to a catalyzer provided in an exhaust line. The catalyzer performs a catalytic reaction between hydrogen gas and nitrogen oxides to achieve decomposition into nitrogen gas and water vapor in the exhaust from an internal combustion engine. The nitrogen oxides are directly reduced with said hydrogen gas in a low temperature atmosphere not higher than 350.degree. C. to achieve efficient reduction in the nitrogen oxides. The improved method and apparatus provide a catalytic system with which the nitrogen oxides in the exhaust from a lean burnt engine or a diesel engine can be effectively reduced irrespective of the concentration of oxygen gas in the exhaust without impairing the good fuel economy of those engines.
摘要:
A catalyst for reducing nitrogen oxides from an exhaust gas containing the same in an oxygen rich atmosphere comprising (i) a zeolite having a molar ratio of SiO.sub.2 /Al.sub.2 O.sub.3 of at least 10, (ii) copper, and (iii) a rare earth ion, an alkaline earth metal and/or a valence variable metal.
摘要:
A process for efficiently reducing nitrogen oxides in exhaust gases including excess oxygen. The process includes intermittently introducing a reducing agent, such as hydrogen and carbon monoxide, for reducing nitrogen oxides to a reducing catalyst, such as platinum, disposed in an exhaust gas passage while maintaining an oxygen excess condition. The reducing agent is intermittently introduced in a manner to satisfy the following equation:[NO.sub.x ]

A privacy protection device acquires provider location information and browser location information indicating the current location of a browser terminal used by a browser who intends to browse the content. The privacy protection device stores determination data for determining whether to mask privacy information included in the content. The privacy protection device determines whether to mask the privacy information by comparing the distance, which is calculated based on the current location of the provider terminal indicated by the provider location information and the current location of the browser terminal indicated by the browser location information, to the determination data stored in the determination data storage part. Finally, the privacy protection device edits the privacy information included in the content so that the privacy information is concealed from the browser when the privacy masking determination part determines to mask the privacy information.

An information distribution device includes: a distribution information management table in which area information at the time of distribution indicating areas in which mobile terminals are located when advertising information is distributed from an information distributing part to the mobile terminals is recorded for each of the mobile terminals to which the advertising information is distributed from the information distribution part; a distribution area evaluation part that calculates, for each of a plurality of areas forming the distribution area and based on the area information at the time of distribution, an area visit probability indicating, of users of the mobile terminals who have been in any of the plurality of area forming the distribution area when the advertising information is distributed from the information distribution part, a percentage of those who have visited a location indicated by the advertising information; and a distribution area updating part that updates distribution area information recorded in a distribution area management table such that the distribution area only includes, of the plurality of areas, those whose area visit probability is equal to or larger than a threshold value.
摘要:
A system and method for determining a failed wireless tag includes capturing images of articles having wireless tags, recognizing an image including wireless tags from among captured images calculating a number of wireless tags and distance information from the reader to each wireless tag based on the recognized image including wireless tags; changing a read range of the reader based on a location wireless tag having a predetermined distance information from the reader; and changing the read range of the reader when a number of wireless tags read by the reader and a number of wireless tags calculated do not match and determining a failed wireless tag based on the changed read range and distance information calculated.
摘要:
The protecting device has a wire passage for wiring the wires led out of the connector. The wire passage includes a first passage part for wiring the wires along a first wiring direction to lead the wires to terminal out of the connector, a second passage part for wiring the wires in a second wiring direction different from the first wiring direction and a third passage part for wiring the wires in a third wiring direction different from the second wiring direction. The third passage part extends in a direction in which the wires are led out of the connector. The protecting device farther has a wire-interference rib formed at a boundary between the second passage part and the third passage part to project in an opposite direction to the direction in which the wires are led out of the connector.
