  • 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.

  • Patent number: 5938413
    Abstract: A plurality of finger members disposed adjacent each other are moved by a driving mechanism in a reciprocal, sequential manner. Infusion is carried out when the finger members engage an infusion tube in a peristaltic sequence. The finger members contact each other by projections formed integrally on the upper and lower surfaces of the finger members to reduce the contact surface area. A fluid diversion guiding hole is contained in a tube-pressing portion of each finger member. The guide holes of adjacent finger members are aligned to form a continuous channel for discharging leaking infusion fluid. Bevels surround the guiding holes and are inclined toward the center of the hole. Each finger member also includes a rib that is integral with and protrudes upward from the upper surface of the finger member for blocking infusion fluid from the finger members and drive mechanism.

  • Patent number: 5899665
    Abstract: A flow sensor detects drops of infusion fluid that enter the drip chamber of an infusion system and generates a drop-detection signal indicating each drop detected. A setting controller receives the drop-detection signals from the flow sensor and counts the drops detected and then determines the fluid-flow rate of infusion fluid into the drip chamber. The setting controller then sets the infusion pump so that the fluid-flow rate of the infusion pump substantially matches the fluid-flow rate of the drip chamber. A motion sensor detects drip-chamber movement and generates a motion-detection signal indicating the motion state of the drip chamber. A maintaining controller is coupled to receive the motion-detection signal from the motion sensor. The maintaining controller also stores a signal that indicates a stationary drip chamber.
