  • Patent number: 7933710
    Abstract: A cylinder causing an abnormal air-fuel ratio is specified. Injection ratio changing control for gradually changing a ratio between command injection quantities of two injectors of the abnormal cylinder while keeping the sum of the command injection quantities of the two injectors constant is performed on the abnormal cylinder. If the injection ratio changing control is performed under the same condition, a changing behavior of the actual sum injection quantity of the two injectors varies and a changing behavior of the air-fuel ratio varies depending on which one of the two injectors is abnormal. Therefore, the abnormal injector out of the two injectors is specified using a learning value of an air-fuel ratio feedback correction value based on an output of an exhaust gas sensor.

  • Publication number: 20110043811
    Abstract: A method for measuring a shape of a phase defect existing on an exposure mask includes making inspection light incident on the mask, measuring the intensity of light scattered in an angular range in which the width of an scattering area on the phase defect can be predicted, calculating a radius of the phase defect based on the measured scattered light intensity, changing the angular range of scattered light to be measured, remeasuring scattered light intensity in the thus changed angular range, and calculating a scattering cross-sectional area based on the scattered light intensity obtained by remeasurement. A process of remeasuring the scattered light intensity and calculating the scattering cross-sectional area is repeatedly performed until the remeasured scattered light intensity is saturated and the shape of the phase defect is determined by using the calculated radius of the phase defect and each of the calculated scattering cross-sectional areas.

  • Patent number: 7832260
    Abstract: An abnormality diagnosis apparatus for an internal combustion engine includes an abnormality diagnosis unit, an other fuel contamination determination unit, and a misdiagnosis prohibition unit. The abnormality diagnosis unit determines whether there is an abnormality in a fuel system based on an output from an exhaust gas sensor mounted on an exhaust duct of the internal combustion engine. The other fuel contamination determination unit determines whether an other fuel contaminates a supply fuel supplied to the internal combustion engine. The misdiagnosis prohibition unit conducts one of (a) changing an abnormality determination condition for the abnormality diagnosis in the fuel system and (b) prohibiting the abnormality diagnosis in the fuel system, when the other fuel contamination determination unit determines that the other fuel contaminates the supply fuel.

  • Publication number: 20100285409
    Abstract: A reverse pattern is formed once by combining a negative exposure mask having a wiring pattern with a positive resist, and then a positive wiring pattern is formed by use of the reverse pattern. That is, a positive resist applied on a semiconductor substrate is exposed by use of the exposure mask having an opening part in a region corresponding to the wiring pattern, and then the exposed part is removed by development to form a resist pattern, thereby forming the wiring pattern in the region corresponding to the opening part of the resist pattern. Consequently, it is hardly affected by flare during EUV exposure, thereby fabricating a fine wiring pattern with higher exposure latitude.

  • Publication number: 20100208978
    Abstract: A inspection image data of the chip A is captured and the data representing the amount of correction of flare corresponded to the chip A is appropriately loaded from the map storage block. Next, a inspection image of the chip A? is captured, and the data representing the amount of correction of flare corresponded to the chip A? is loaded from the flare map storage block as the amount of shifting of the edge of the contour of the pattern. The amount of correction is converted, by a correction data generation block which is a correction data generator, into the amount of geometrical correction of pattern which provides correction data. In the comparison block, the images of the geometry of two chips are compared and corrected on the amount of correction of flare generated by a correction data generation block, to thereby judge whether defect is found or not.

  • Patent number: 7630068
    Abstract: Defect detection is performed with two settings, that is, setting of a focus position where a signal intensity obtained from a dot pattern is maximum and setting of a focus position where a signal intensity obtained from a hole pattern is maximum. In addition, defect detection is performed at a predetermined focus position previously set and for the detected defect, the focus position is changed at that position to find a focus position where the signal intensity is maximum. If the focus position is away from a signal light-receiving system, the defect is determined as dot-shaped. If the focus position is close to the signal light-receiving system, the defect is determined as hole-shaped. If the focus position is intermediate of them, the defect is determined as an elongated-shaped.
