摘要： A diesel particulate filter (41) which traps particulate matter contained in the exhaust gas of a diesel engine (1) comprises an oxidation catalyst (41A) which exhibits a temperature-raising effect during regeneration of the filter (41). A controller (31) calculates the amount of particulate matter trapped in the filter (41) at the start of regeneration as a first amount, and calculates the amount of particulate matter burned during regeneration of the filter (41) as a second amount (S3, S10, S18). A deterioration factor d of the oxidation catalyst is calculated from the ratio of the second amount and first amount, and a target temperature for the next regeneration of the filter is determined on the basis of this deterioration factor d. Thus deterioration of the oxidation catalyst (41A) is compensated for, and an optimum temperature environment for regenerating the filter (41) is realized.

摘要： A diesel engine (1) comprises an exhaust passage (3), and a DPM filter (4) provided on the exhaust passage (3), which traps diesel particulate matter (DPM) contained in the exhaust gas such that the diesel particulate matter accumulates therein. An engine controller (11) starts regeneration processing of the DPM filter (4) by raising the exhaust gas temperature when a regeneration timing of the DPM filter (4) is reached, sets a target exhaust gas temperature during regeneration processing to ensure that the temperature of the DPM filter (4) does not exceed an upper temperature limit of the DPM filter (4), even when the temperature of the DPM filter (4) is raised due to the engine (1) entering an idling condition during the regeneration processing, and controls the exhaust gas temperature to the target exhaust gas temperature.

摘要： To regenerate a diesel particulate filter (10) which traps particulate matter contained in the exhaust gas of a diesel engine (20), a controller (16) raises the temperature of the exhaust gas through fuel injection control of a fuel injector (23), and thus burns the particulate matter trapped in the filter (10). The controller (16) cumulatively calculates the time during which the temperature of the filter (10) exceeds a target temperature as an effective regeneration time. By estimating the amount of particulate matter remaining in the filter (10) on the basis of the effective regeneration time, the controller (16) estimates the amount of remaining particulate matter with a high degree of precision and without consuming energy, whereupon regeneration of the filter (10) through fuel injection control ends.

摘要： The present invention provides a digital signal processing apparatus and a method for controlling the apparatus that allow for a reduction of circuit size to minimize an increase in power consumption and the costs of circuitry and an improvement in signal processing speed. To achieve this, the present invention eliminates a circuit arrangement that was conventionally required for executing a compare instruction, conditional jump instruction, and jump instruction, by adding a relatively small-sized circuit such as an encoder 51 for processing an external signal 10 and a capability of decoding a condition determination data select instruction.

摘要： An echo canceler (34) includes a summing device (104) that subtracts a correction signal from a received signal, the difference of which represents the far-end signal with an error component. Instead of adapting its coefficients using the output of the summing device (104), the echo canceler (34) uses the difference between the input and output of a decision device (108) as an estimate of the error component alone. The estimate of the error component is then used to adapt the coefficients according to the adaptive least mean squares (LMS) algorithm. In one embodiment, the decision device (108) forms discrete multi-tone symbols based on the equalized output of the summing device. In this embodiment, the echo canceler (34) performs an inverse of the equalization step efficiently by replacing a division operation with a multiply operation and a corresponding power-of-two shift operation.

摘要： Input terminals to which two types of serial data with similar formats are sent are disposed. Video data sent to the normal dubbing input terminal is data that has not been compressed/encoded. Data sent to the straight dubbing input terminal is data that has been compressed and encoded. Data received from the input terminal includes a sync error flag (error flag for each sync block) that is OR output data of data added by a reproducing VTR and transmission error information. The sync error flag is sent to an ECC encoder through a format converter not through an BRR encoder. An output signal of an ECC encoder is recorded to a magnetic tape by recording heads through a recording driver.

摘要： A signal processing method and apparatus wherein digital image data is compressed, recorded, and edited and where multiple playback/record cycles do not degrade the quality of the image. Digital image signals are compressed and recorded by a digital VTR. The recorded signals are then played back and the resulting signal is decompressed along one data path or inserted into a standard video interface format signal along a second data path. The compressed image signal in the standard video format may then be edited as if it were a standard video signal. The compressed video signal is then extracted from the standard interface signal and rerecorded. The compressed signal can be edited without decompression and recompression, thus maintaining the quality of the image data.
