  • Patent number: 8899019
    Abstract: An air-fuel ratio control apparatus of the present invention includes a determination section and a reverse direction correction introducing section. The determination section determines whether or not an output of the downstream air-fuel ratio sensor falls within a predetermined range whose center corresponds to a target value corresponding to the stoichiometric air-fuel ratio. When the output of the downstream air-fuel ratio sensor falls within the predetermined range, the reverse direction correction introducing section temporarily introduces, to an air-fuel ratio correction in a direction requested by the output, an air-fuel ratio correction in a direction opposite to the requested direction.

  • Patent number: 8887491
    Abstract: A control apparatus for an internal combustion engine determines, based on an output value of the downstream air-fuel ratio sensor, an air-fuel ratio of a gas flowing into the catalyst that is set to either a “target rich ratio” or a “target lean ratio”, and determines a fuel injection amount. Disclosed is an evaporated fuel purge section for introducing an evaporated fuel generated in a fuel tank into an intake passage. The purge section starts the purge when the target air-fuel ratio is set to the target rich ratio at a purge execution condition satisfied time point at which a state has changed from a state in which the purge execution condition is unsatisfied to a state in which it is satisfied, and does not start the purge when the target air-fuel ratio is set to the target lean air-fuel ratio at the purge execution condition satisfied time point.

  • Patent number: 8844858
    Abstract: A wire winding device which uses a large-sized supply bobbin, which has a large capacity and a large diameter, to highly precisely suppress a variation in tension which variation occurs when a coil is formed by winding a wire material at high speed with the wire material aligned with a winding frame. Rotation (the number of rotation, and timing) of the supply bobbin relative to rotation of the coil is controlled based on the difference between the amount of take-up of the wire material taken up on the winding frame side and the amount of pay-out of the wire material paid out from the supply bobbin, and the control is performed such that the amount of the take-up and the amount of the pay-out agree with each other every moment. This can highly precisely suppress a variation in tension even if there are large differences between inertia of and the diameters of the coil and the supply bobbin.

  • Publication number: 20140283504
    Abstract: An air-fuel ratio control apparatus for an internal combustion engine according to an embodiment of the invention (the present control apparatus) sets a target air-fuel ratio to a target rich air-fuel ratio when it is determined on the basis of the output value Voxs of a downstream air-fuel ratio sensor 67 that the oxygen adsorption amount of a catalyst 43 tends to be excessive, and sets the target air-fuel ratio to a target lean air-fuel ratio when it is determined on the basis of the output value Voxs that the oxygen adsorption amount of the catalyst 43 tends to be insufficient. Further, the present control apparatus determines whether or not an operation state in which a large amount of nitrogen oxide flows into the catalyst 43 is reached on the basis of “whether a predetermined condition is fulfilled”, and makes the target rich air-fuel ratio obtained when the predetermined condition is fulfilled less than the target rich air-fuel ratio obtained when the predetermined condition is not fulfilled.

  • Publication number: 20140270869
    Abstract: A fixing device includes an endless belt member, a secured member disposed to contact the belt member, a heating unit that heats the belt member, and a rotary pressurizing roller including an elastic layer that is elastically deformed when the belt member is pressed against a pressing surface of the secured member to form a fixing part. The pressurizing roller is curved such that a center portion is smaller in outside diameter than end portions along the axial direction. The pressing surface is curved such that a center portion projects toward the pressurizing roller more than end portions along the longitudinal direction. On the pressing surface, an amount of projection of the center portion with respect to the end portions along the longitudinal direction is set to be larger on an output side than on an input side of the fixing part along a moving direction of the belt member.

  • Publication number: 20140211262
    Abstract: In an image processing apparatus, a memory area management portion generates a descriptor for a block storage area allocated in each of a first work memory and a second work memory, and generates sub-band management data associated with the descriptor for the block storage area in which compressed sub-band data is stored, sequentially according to arrangement of the sub-band data in the primary scanning direction and the secondary scanning direction in image data. A data loading portion changes, according to a rotation angle, the association between the sub-band management data and the descriptor after the compressed sub-band data is stored in the second work memory. A decompression processing portion performs rotating process in the sub-band data according to the rotation angle.

  • Publication number: 20140176994
    Abstract: An image forming apparatus includes an image reading section, an image processing section, an image forming control section, and an image forming section. The image reading section is configured to read an original document and output a band data set for one band. The image processing section is configured to compress the band data set at a first compression rate to generate a first compressed band data set, expand the first compressed band data set, and subject the expanded band data set to image processing. Thereafter, the image processing section compresses the band data set subjected to the image processing at a second compression rate to generate a second compressed band data set. When the number of second compressed band data sets reaches a printing start value, the image forming control section allows the image forming section to start forming an image based on the second compressed band data sets.

  • Patent number: 8650943
    Abstract: An air-fuel ratio imbalance among cylinders determining apparatus according to the present invention is applied to a multi-cylinder internal combustion engine in which a compression ratio is variable. The determining apparatus obtains, using at least an output value of an upstream air-fuel ratio sensor disposed for a catalyst, an “imbalance determining parameter” which becomes larger as a degree of an imbalance among “individual cylinder air-fuel ratios” becomes larger, each of the individual cylinder air-fuel ratios being an air-fuel ratio of a mixture supplied to each of cylinders. Further, the determining apparatus determines that an air-fuel ratio imbalance state among cylinders is occurring, when the imbalance determining parameter is larger than a predetermined threshold. The determining apparatus changes the predetermined threshold in accordance with a mechanical compression ratio of the engine.

  • Patent number: 8534046
    Abstract: A catalyst deterioration diagnosing apparatus is provided with means for performing stoichiometric feedback control on the air-fuel ratio based on at least output from an upstream air-fuel ratio sensor provided upstream of a catalyst, means for measuring the oxygen storage capacity of the catalyst, and means for correcting the measured value of the oxygen storage capacity based on at least the output behavior of a downstream air-fuel ratio sensor provided downstream of the catalyst during the stoichiometric feedback control. The measured value of the oxygen storage capacity is corrected using the output behavior of the downstream air-fuel ratio sensor during stoichiometric feedback control. The diagnostic is performed after eliminating the effects from sulfur by correcting the measured value to a value corresponding to when low sulfur fuel is used, which makes it possible to prevent an erroneous diagnosis from being made.
