According to one embodiment, magnetic reproducing element for detecting a magnetic field from a magnetic recording medium comprises a sensor film including a perpendicular magnetization film having a magnetization easy axis in a direction perpendicular to a film plane, wherein magnetization in the sensor film tilts upward or downward in an element height direction from the magnetization easy axis while no magnetic field is applied from the magnetic recording medium, and change in anomalous Hall voltage generated in the sensor film is detected, thereby allowing the magnetic field applied from the magnetic recording medium to be detected. Other magnetic reproducing elements and magnetic heads employing magnetic reproducing elements are described as well.

The interest of a user of an information terminal is extracted by a file operation and information suited to the interest is provided. When a system call for file access is issued from an application program, an access processor 104 selects from a file storage unit 102 a file designated by the system call, and then performs the file access. A phrase extractor 106 extracts a plurality of phrases from the file in accordance with a predetermined extraction rule. Those of the keywords stored in a keyword storage unit 110 that match the extracted phrases are selected. A score processor 120 assigns to the selected keyword a weight suited to the situation of access to the file by the access processor 104. An information selector 150 receives the weighted keyword and determines a prioritized keyword. Useful information corresponding to the priority keyword is selected from a useful information storage unit 130 and displayed on a display of an information terminal.

An image processing apparatus reducing image noise caused at a device which has a stationary reading portion such as a CCD sensor and reads an image of a document by moving the document is structured as follows: the image processing apparatus determines whether full color image data read by the reading portion is out of a predetermined color space; it uses shift resisters to determine that the image data out of the predetermined color space continues in a sub scanning direction; and thus it detects a line-shaped dirt image caused by dirt or the like at the reading portion, and corrects the dirt image.

A gradient charged particle beam apparatus capable of moving highly accurately to a specific position by eliminating influences of warp inside a wafer surface is provided. A portion 46 having a mark 47 for aligning visual field alignment positioned in advance to the same horizontal and the same height as a stage plane as a reference point is arranged on a wafer holder. A height of an observation point on a sample is adjusted to the height of the mark 47 and the visual field of a gradient column is brought into conformity with the visual field of a vertical column by use of a known offset between the gradient column and the vertical column at that time.
