  • Patent number: 7963269
    Abstract: A 90° integrated value calculating unit of an engine ECU calculates a 90° integrated value obtained by integrating a magnitude. A calculating unit calculates a knock magnitude by dividing 90° integrated value by a BGL. A value obtained by subtracting a standard deviation ? from a median value of 90° integrated value is determined as the BGL. An ignition timing control unit controls the ignition timing depending on whether knock magnitude is equal to or larger than a determination value. A median value calculating unit calculates median value of 90° integrated value. A standard deviation calculating unit calculates standard deviation of 90° integrated value. A first stop unit stops updating of median value and standard deviation when 90° integrated value is smaller than a first threshold value or is equal to or larger than a second threshold value.

    Abstract: At least two drain ohmic contacts are arranged to intersect with an active area. A source ohmic contact is arranged between the drain ohmic contacts. A drain coupling portion on an element separating area couples ends of the drain ohmic contacts on the same side thereof. A gate power supply wiring on the element separating area couples gate fingers at the end thereof on the opposite side of the arrangement side of the drain coupling portion. A gate edge coupling portion couples two gate fingers adjacent to each other, sandwiching the source ohmic contact at the end thereof on the arrangement side of the drain coupling portion. The gate edge coupling portion does not intersect with the drain ohmic contact and the drain coupling portion.

  • Patent number: 7926906
    Abstract: A necessary amount of suppression ink is applied to each portion of an ink absorber in a short time and in an efficient manner. For that end, carriage scan is performed while changing an ejection condition of suppression ink so as to change an application amount of suppression ink according to a position of an ink absorber. This makes it possible to appropriately apply suppression ink, which suppresses accumulation of ink, to the entire area of the ink absorber by carriage scan in a short time even if an application amount of accumulation ink differs from part to part of the ink absorber.

  • Publication number: 20090223280
    Abstract: An output signal of a knock sensor is converted by an A/D conversion part in a specified knock determination range. In a time-frequency analysis part, data of frequency, time, and vibration intensity are extracted at the same time from an output signal of the knock sensor and the time-varying patterns of vibration intensities in multiple frequency ranges are extracted. A knock determination part computes lengths (crank angle, or time period) from a starting point to a latest terminating point of the time-varying patters of vibration intensity in at least two frequency ranges, which rise at a same time. The knock determination part executes a knock determination based on whether the lengths are greater than a knock determination threshold.

  • Publication number: 20090217738
    Abstract: A knock sensor signal is converted by an A/D conversion part in a specified knock determination range. In a time-frequency analysis part, data of frequency, time, and vibration intensity are extracted at the same time from an output signal of the knock sensor and the time-varying patterns of vibration intensity of multiple frequency ranges are extracted. Contours of the time-varying patterns of vibration intensity in multiple frequency ranges are extracted. Vectors indicating directions along which the vibration intensities vary are approximated by the contour of the time-varying pattern of vibration intensity in each frequency range according to the least-squares method. A knock determination is executed based on whether directions of any two or more of multiple vectors are within a predetermined range. Alternatively, a knock determination is executed based on whether a ratio of length of any two or more of the vectors is within a predetermined range.

  • Publication number: 20090211337
    Abstract: An output of a knock sensor is A/D converted in a specified knock determination range. In a time-frequency analysis part, data of frequency, time, and vibration intensity are extracted at the same time from the knock sensor output signal and the time-varying patterns of vibration intensities in multiple frequency ranges are extracted. An edge direction and an edge intensity are computed by an edge extraction processing. A correlation value expressing a correlation between time-varying patterns of vibration intensities in multiple frequency ranges and a reference model expressing the feature of knock is computed in a mutual correlation/knock determination part. The correlation value is compared with a determination threshold. When the correlation value is larger than the determination threshold, it is determined that knock is caused. When the correlation value is not larger than the determination threshold, it is determined that knock is not caused.
