    摘要: A subpicture image signal vertical compression circuit for vertically compressing subpictures operating at respective synchronous timings different from that of the main picture when a plurality of image signals having respectively different synchronizations are displayed on an image display device. Depending on whether the field polarities of main and sub pictures are the same or not, the subpicture image signal vertical compression circuit generates suitable offsets for the first and the second fields to adjust the phases and prevent the inversion of the scan order in the vertical direction, at the first field and the second field of subpicture signal, after the phase adjustment to obtain a subpicture image with natural motion in the vertical direction.

    摘要: An image display device includes: an interpolation phase generator that generates an interpolation phase on the basis of downsampling frame information representing a downsampling timing at which at least one frame image of the image signal is thinned, and an interpolation frame generator that generates an interpolation frame image corresponding to the interpolation phase. The interpolation phase generator generates the interpolation phase such that a phase distance between a first interpolation frame image from among a plurality of interpolation frame images within one period of downsampling periods, and a second interpolation frame image that follows the first interpolation frame image becomes equal to a phase distance between mutually adjacent interpolation frame images obtained when phase distances between a plurality of interpolation frame images are equalized within one period of the downsampling periods.

    摘要: In a control device for an internal combustion engine provided with a NOx catalytic converter in an exhaust passage thereof, the progress of an undesired substance removal process is computed from the consumption of the reducing agent contained in the exhaust gas in the NOx catalytic converter. The undesired substance may include sulfur contents and NOx captured in the NOx catalytic converter. This computation may be based on the air fuel ratio of the exhaust gas upstream of the NOx catalytic converter and the estimated consumption of the reducing agent contained in the exhaust gas or on the difference between the air fuel ratios of the exhaust gas upstream and downstream of the NOx catalytic converter. In either case, the accuracy can be improved by taking into account the space velocity of the exhaust gas.

    摘要: An exhaust emission control device for an internal combustion engine, which is capable of accurately estimating the amount of NOx trapped by a NOx catalyst even when a catalyst is provided on an upstream side of the NOx catalyst. A catalyst having the function of purifying NOx and a NOx catalyst for trapping NOx under an oxidizing atmosphere are disposed in an exhaust system. The amount of NOx contained in exhaust gases is estimated. A NOx purification performance of the catalyst is calculated. The NOx emission amount is corrected based on the purification performance. An amount of NOx trapped in the NOx catalyst is calculated based on the corrected NOx emission amount. A reducing agent is supplied to an upstream side of the catalyst based on the trapped NOx amount, thereby causing the NOx catalyst to carry out a NOx reducing operation.

    摘要: An exhaust emission control device for an internal combustion engine, which is capable of supplying a just enough amount of reducing agent to the NOx catalyst even when a catalyst is provided on an upstream side of the NOx catalyst. A catalyst and a NOx catalyst are disposed at respective upstream and downstream locations in an exhaust system, for purifying NOx and for trapping NOx under an oxidizing atmosphere and reducing the NOx under a reducing atmosphere, respectively. An air-fuel sensor is disposed between the catalyst and the NOx catalyst. A reducing agent is supplied to an upstream side of the catalyst, to control exhaust gases such that the gases form the reducing atmosphere. To determine time of termination of NOx reduction control, an amount of reducing agent supplied to the NOx catalyst is calculated, and calculation of the amount of reducing agent is started when the air-fuel ratio has converged within a vicinity of a target air-fuel ratio.

    摘要: A NOx removing device 4 having NOx absorbing capacity and ammonia retaining capacity is provided in an exhaust pipe 2 of an internal combustion engine 1. A reforming catalyst 3 is disposed upstream of the NOx removing device 4. The reforming catalyst 3 generates hydrogen and carbon monoxide by the steam reforming reaction, when the exhaust gases are in the reducing state. Hydrogen and carbon monoxide generated by the reforming catalyst 3 are supplied to the NOx removing device 4, and contribute to generation of ammonia. The generated ammonia is retained in the NOx removing device 4 and reduces NOx in exhaust gases when the exhaust gases are in the oxidizing state.
