    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.

    摘要: A magnetic detection device includes a sensor unit including a sensor pattern having a plurality of magnetoresistance effect films whose ends in the length direction thereof are coupled via return portions, and electrode units formed at both ends of the sensor pattern in the longitudinal direction thereof. A non-magnetic conductor is electrically connected across a top surface of one of a pair of magnetoresistance effect films that are coupled via the corresponding one of the return portions and that face each other and a top surface of the other magnetoresistance effect film. Therefore, the resistance value between the electrode units can be adjusted without increasing the dimensions of the sensor unit, and deterioration or variation in magnetic characteristics can be reduced.

    摘要: A magnetic detecting device includes a first and a second magnetoresistive element, and a first and a second fixed resistor connected in series to the first and the second magnetoresistive element, respectively. The first and the second magnetoresistive element each include a pinned magnetic layer and a free magnetic layer with a nonmagnetic conductive layer in between. The first and the second magnetoresistive element have the same layer structure except that the nonmagnetic conductive layers have different thicknesses. The thicknesses of the nonmagnetic conductive layers are set so that a positive interlayer coupling magnetic field acts between the free magnetic layer and the pinned magnetic layer of the first magnetoresistive element and a negative interlayer coupling magnetic field acts between the free magnetic layer and the pinned magnetic layer of the second magnetoresistive element. The first and the second fixed resistor have the same layer structure.

    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.
