  • Patent number: 6756904
    Abstract: The permeability of a DPF 21 mounted on a diesel engine 1 is evaluated by calculating the apparent passage area (A) based upon a difference in the pressure between the upstream and the downstream sides of the DPF 21 and upon other engine data, an alarm is given to a driver based on the results of evaluation, and the operation mode is changed over to regenerate the DPF 21. An abnormal increase in the passage area caused by breakage is accurately detected, and it does not happen that the PM is released into the open air for extended periods of time due to the breakage of the DPF 21. Further, without the need of dismantling the DPF 21, the DPF 21 can be reliably burned and regenerated without being undesirably overheated in every operation mode of the engine 1.

  • Publication number: 20030091424
    Abstract: An intermediate guide member is provided attachable and removable between a head portion and a supporting frame of a stocker for printing plates. A number of intermediate guide members is an element to set a time of starting downward movement of hooks supporting a leading end of a printing plate. Three conditions in accordance with lengths of non-detection times are set for detecting the printing plate to judge authenticity of the detection. When the hooks reach vicinities of stoppers provided at supporting bars of a reversal unit, the hooks swing, are pulled-in from above the slope, and transfer the printing plate to the stoppers. Thereafter, by rotating the supporting bars and the stoppers integrally around a shaft, the printing plate is pivoted over toward a back plate, and a lower end of the printing plate is transferred from the stoppers to a receiving plate without damaging the printing plate.

  • Publication number: 20020192519
    Abstract: An output limitation warning lamp is turned on when a possible output Qf of the fuel cell is less than a predetermined value L2. The output limitation warning lamp is provided at a combination meter in an instrument panel. The output limitation warning lamp is also turned on when a possible output Qb of the secondary battery is less than a predetermined value L3. Furthermore, the output limitation warning lamp is also turned on when an allowable drive output Qh, which is the sum of the possible output Qf of the fuel cell and the possible output Qb of the secondary battery, has been less than a required output Ed* calculated at a step before carrying out output limitation to more than a certain extent for longer than a predetermined length of time.

  • Patent number: 5648050
    Abstract: It is the primary object of the present invention to provide a catalyst converter which can hold a sufficient amount of catalyst to raise the temperature thereof to the catalyst activation temperature in a short time without enlarging the metal carrier itself. The metal carrier 1 is arranged in the course of an exhaust manifold 3 of an engine 2 and is composed of an alternating winding of a flat sheet 7 and a corrugated sheet 8, wherein slit parts 9 are formed in the flat sheet 7 and the corrugated sheet 8 of the metal carrier 1 in an end portion thereof, on the side the engine 2.

  • Patent number: 5599509
    Abstract: In a metal catalyst converter configured of the metal catalyst carrier that holds the catalyst into the honeycomb body created by alternately winding flat sheet and corrugated sheet, a plurality of slit matrix that extend in the direction perpendicular to the exhaust gas direction were arranged on at least one part of the upstream side of the exhaust gas passage. By that a low heat capacity and high heat transfer area in regard to the downstream side of the exhaust gas passage was formed. The upstream portion of the metal catalyst converter on which slit matrix was formed was configured to be covered by outer casing having an air insulation layer. The upstream side of this outer casing was held and fixed to the exhaust gas passage.
