    摘要: A pattern inspection apparatus determines a difference of the measured dislocation of respective alignment marks of an opaque pattern and a phase shifting pattern (measurement difference), in addition to a difference between the both alignment mark positions in design (design difference). A difference between the measurement difference and the design difference is set as a difference in alignment mark position between the opaque pattern and the phase shifting pattern in a reference pattern which is later used in inspection. In this manner, by correcting one pattern data with respect to the other pattern data in the reference pattern, the displacement generated in the both patterns can be reflected, and the reference pattern data regarding an image of a sample which is actually observed can be created.

    摘要: An image correction device for use in a pattern inspection apparatus is disclosed, which has automatic adaptability to variations in density of a pattern image of a workpiece being tested. The device is operable to identify a two-dimensional (2D) linear predictive model from the pattern image of interest and determine the amount of eccentricity of a centroid position of this model. This amount is then used to switch between a corrected pattern image due to the 2D linear prediction modeling and a corrected image that is interpolated by bicubic interpolation techniques. A pattern inspection method using the image correction technique is also disclosed.

    摘要: The present invention is to allow rapid detection of such a defect as buried in a pixel positional deviation, expansion/contraction noise or sensing noise on an image. A relationship between an inspection reference pattern image and a pattern image to be inspected is identified during inspection to construct a mathematical model obtained by absorbing (applying fitting on) a pixel positional deviation, expansion/contraction noise or sensing noise on an image, and a defect is detected by comparing a new inspection reference pattern image (model image) obtained by simulating the mathematical model and a pattern image to be inspected.

    摘要: A normal-direction mode which switches on first and fourth switches and in a mutually diagonal relationship of an H-type bridge circuit and switches off second and third switches also in a mutually diagonal relationship of the bridge circuit is executed for an on-duty time of an opening-degree command signal, and a reverse-direction mode which switches off the first and fourth switches and switches off the second and third switches is executed for an off-duty time of the opening-degree command signal. During normal operation, conduction of current to the H-type bridge circuit 70 and a coil is constantly performed irrespective of a degree of opening of a valve to be adjusted, and in a case where conduction is interrupted, it can be presumed that a broken wire has occurred in the H-type bridge circuit or coil, and determination of a broken wire can be made.

    摘要: A magnetic sensor includes magnetoresistive elements and a soft magnetic body. The magnetoresistive elements have multi layers including a magnetic layer and a nonmagnetic layer on a substrate, and exert a magnetoresistance effect. The soft magnetic body is electrically disconnected with the magnetoresistive elements, and converts a vertical magnetic field component from the outside into a magnetic field component in a horizontal direction so as to provide the magnetoresistive elements with the horizontally converted magnetic field component. The magnetoresistive elements have a pinned magnetic layer having a fixed magnetization direction and a free magnetic layer having a variable magnetization direction. The free magnetic layer is stacked on the pinned magnetic layer with a nonmagnetic layer interposed between the free magnetic layer and the pinned magnetic layer. The magnetization directions of the pinned magnetic layers of the magnetoresistive elements are the same direction. The magnetoresistive elements form a bridge circuit.

    摘要: A first determiner determines whether a pressure in a fuel tank is within a predetermined range when an ignition switch of an engine is on. A second determiner determines whether a valve allows or prohibits a communication between the fuel tank and a switch valve, when the first determiner determines that the pressure in the fuel tank is within the predetermined range. A control unit controls a pressure controlling portion based on a determination result of the first determiner and a determination result of the second determiner. A leak determiner determines whether the fuel tank has a leak of evaporated fuel based on a signal output from a first detector detecting a pressure in a detection passage and a signal output from a second detector detecting a pressure in the fuel tank.

    摘要: An ECU determines whether condensed water is present at a rotor and vanes based on an electric current, which flows in an electric motor that drives the rotor. When the condensed water is determined to be present, the ECU drives the motor for a predetermined time period. When the condensed water is determined to be absent, the ECU stores a pressure, which is sensed through a pressure sensor, as a first pressure. The ECU is adapted to sense an abnormality in a pump characteristic based on a value of the first pressure.
