  • Patent number: 7093432
    Abstract: An exhaust gas purification apparatus for use in an internal combustion engine comprises an exhaust gas duct connected to the engine through which the exhaust gas containing NOx gas passes and a catalyst so disposed in the exhaust gas duct that it contacts with the exhaust gas. The catalyst chemically adsorbs NOx under the condition that a stoichiometric amount of a gaseous oxidizing agent present in the exhaust gas is larger than that of a gaseous reducing agent present in the exhaust gas for reducing NOx, while NOx being adsorbed is catalytically reduced in the presence of the reducing agent under the condition that the stoichiometric amount of the oxidizing agent is not larger that of the reducing agent. Thereby, NOx, the lean burn exhaust gas in the engine can be effectively made harmlessly.

  • Publication number: 20060060804
    Abstract: A cassette is delivered from a cassette loader through a stock unit to a releasing unit. After a stimulable phosphor panel is supplied from the cassette to a reading unit by an unlocking mechanism and a panel ejecting mechanism, the cassette is fed to a position below an erasing unit so as to wait for the stimulable phosphor panel. After recorded radiation image information is read from the stimulable phosphor panel by the reading unit, the stimulable phosphor panel is fed to the erasing unit, which erases remaining radiation image information from the stimulable phosphor panel. Thereafter, the stimulable phosphor panel is stored back into the waiting cassette, which is delivered to a cassette discharger.

  • Publication number: 20060029526
    Abstract: An exhaust gas purification filter for a diesel internal combustion engine. In this filter, catalyst layers are not formed at portions to which a sealant of the filter is stuck so that a substrate of the honeycomb structure is exposed, but formed at portions to which a substrate of the honeycomb structure is exposed. If the sealant is stuck to catalyst layer portions, because the catalyst layers are brittle and the surfaces thereof have asperities, the fixing strength of the sealant is reduced, so that the sealing portions becomes prone to falling-off under shocks or the like. By exposing the substrate of the honeycomb structure and sticking the sealant to the exposed portions, it is possible to enhance the fixing strength of the sealant and thereby to prevent the sealing portions from falling off.

  • Publication number: 20050188684
    Abstract: In an exhaust gas purifying apparatus provided with a lean NOx catalyst supporting a catalyst layer, which contains a NOx trapping component, on a honeycomb substrate formed so as not to cause an alkali attack, the invention prevents trapped NOx from being dissociated and exhausted during the time of a rich spike. A NOx reducing catalyst with the function of reducing NOx by a reductant in a rich or stoichiometric condition, e.g., a three-way catalyst, is disposed downstream of the lean NOx catalyst. In the case of increasing the amount of the NOx trapping component in the lean NOx catalyst to enhance a NOx trapping capability, even if a part of trapped NOx is dissociated during the time of the rich spike, the dissociated NOx can be reduced by the NOx reducing catalyst disposed on the downstream side.

  • Publication number: 20050156126
    Abstract: After a housing of a cassette is opened by a suction cup, then a stimulable phosphor sheet is removed from the cassette by a shiftable roller and then fed in an auxiliary scanning direction by a feed mechanism. While being fed in the auxiliary scanning direction, the stimulable phosphor sheet is irradiated with a laser beam emitted from a stimulating optical system. Light emitted from the stimulable phosphor sheet upon exposure to the laser beam is guided through a light guide to a photoelectric transducer. After the recorded radiation image information is read from the stimulable phosphor sheet, the stimulable phosphor sheet is stored back into the cassette, and erasing light from erasing light sources is applied to the stimulable phosphor sheet in the cassette to erase remaining radiation image information from the stimulable phosphor sheet.

  • Publication number: 20040115104
    Abstract: A catalyst for use in purifying exhaust gas from an internal combustion engine. The active components of an exhaust gas purification catalyst for an internal combustion engine tend to be melted or softened and then to move outside the carrier, because the components become in contact with exhaust gas at a high temperature. Hence, anchoring materials are provided between carriers in order to suppress the moving of catalytically active components. Anchoring materials 22 do not form compounds with catalytically active components 24, and are selected from substances that do not melt even in contact with exhaust gas at a high temperature. When the active components contain sodium, potassium, cesium, lithium, strontium, barium, noble metals and the like, the best anchoring material is MgO. The anchoring material functions as a barrier that prevents the moving of active components.
