摘要:
An output signal of a knock sensor is filtered with a plurality of band-pass filters to extract vibration waveform components of a plurality of frequency bands (f1-f4). Weighting coefficients (G1-G4) which multiply the vibration waveform component of each frequency band are established in such a manner as to be a small value as a noise intensity of each frequency band becomes larger. Thereby, the vibration waveform component of a plurality of frequency bands is synthesized by weighting according to an influence of a noise intensity of each frequency band. Even when the noise is superimposed on the vibration waveform component of any of the frequency bands, it becomes possible to reduce the influence of the noise and to synthesize the vibration waveform component of each frequency band, and an accurate knock determination can be performed based on the composite vibration waveform.

An engine ECU executes a program including the steps of: calculating a knock magnitude N by dividing an integrated value lpkknk obtained by integrating the magnitude of vibration in the knock detection gate by BGL; controlling ignition timing according to a result of comparison between knock magnitude N and a determination value VJ; stopping updating of a standard deviation σ when it is determined that determination value VJ to be compared with knock magnitude N is to be changed; updating a median value VM by increasing an update amount of median value VM; and updating BGL according to median value VM and standard deviation σ.

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 σ 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.

Provided are an inkjet printing apparatus and inkjet printing method that can, regardless of an ejection frequency of a print head, stabilize density of an image expressed on a print medium. For this purpose, an ink concentration integrated value is obtained according to the ejection history of each nozzle so as to be increased by data indicating non-ejection of the nozzle or decreased by data indicating ejection. Then, image data on the target pixel is corrected such that density of the target pixel is further reduced as the pixel is subjected to printing by a nozzle having a higher ink concentration integrated value.

An object of the present invention is to provide a liquid applying apparatus which can inhibit a variation in application amount associated with the individual variability of a component of the apparatus. According to the present invention, a liquid holding space in which a liquid is held is formed between the applying member and the liquid holding member. When the applying member moves, the liquid attached to the applying member is fed out of the liquid holding space together with the applying member. The liquid is applied to a medium. The application amount of liquid applied to the applying medium varies depending on the individual variability of a component such as a liquid applying member. The variation in liquid application amount is adjusted by adjusting section for adjusting, the rotation speed of the liquid holding member or the flow speed of the liquid flowing through the liquid holding space.

A control unit 6 causes a vertical scanning circuit 3 to cyclically select any one-dimensional pixel line from among pixel lines 21 to 23 each time a prescribed H period elapses, and controls a read circuit 5 and a horizontal scanning circuit 4 so as to read out pixel signals of an object which has been exposed by the selected pixel line.
