  • Patent number: 10704440
    Abstract: An exhaust purification system includes an LAF sensor provided in an exhaust pipe and generates a signal corresponding to an air-fuel ratio of exhaust gas. An upstream catalytic converter is downstream of the LAF sensor and has a catalyst to purify the exhaust gas. An O2 sensor is downstream of the upstream catalytic converter, and generates a signal corresponding to the air-fuel ratio of the exhaust gas. A GPF is downstream of a the O2 sensor and purifies the exhaust gas. An ECU controls an air-fuel mixture in an engine using output signal KACT of the LAF sensor and an output signal VO2 of the O2 sensor such that the air-fuel ratio of exhaust gas flowing into the GPF converges to a target value near the stoichiometric ratio. The GPF has a filter substrate and a downstream TWC supported by a partition of the filter substrate.

  • Patent number: 9619184
    Abstract: There is provided an image forming apparatus. A transmitter is configured to transmit a test pattern in advance to another image forming apparatus when transferring print data to the another image forming apparatus. An acquirer is configured to acquire an optical reading result of an output of the test pattern made by the another image forming apparatus. A corrector is configured to correct the print data on the basis of the reading result so that the print data is output at the another image forming apparatus in the same quality as the image forming apparatus. A transfer unit is configured to transfer the corrected print data to the another image forming apparatus when the corrected print data does not include data which is not output at the another image forming apparatus in the same quality as the image forming apparatus.
