摘要： A magnetic sensor is constituted using magnetic sensor chips mounted on stages supported by interconnecting members and a frame having leads in a lead frame. Herein, the stages are inclined upon plastic deformation of the interconnecting members. When the frame is held in a metal mold and the stages are pressed, the interconnecting members are elastically deformed, so that the magnetic sensor chips are bonded onto the stages placed substantially in the same plane and are then wired with the leads. Thereafter, the stages are released from pressure, so that the interconnecting members are restored from the elastically deformed states thereof. When the magnetic sensor chips are combined together to realize three sensing directions, it is possible to accurately measure three-dimensional bearings of magnetism, and the magnetic sensor can be reduced in dimensions and manufactured with a reduced cost therefor.

摘要： In an azimuth/inclination-angle detection apparatus, a measurement data obtaining unit obtains first and second measurement data sets g and h from acceleration and magnetic sensors, respectively. A first computation unit calculates an azimuth α0, an elevation angle β0, and a geomagnetism depression angle θ0 from the measurement data sets g and h. An averaging unit accumulates and averages the geomagnetism depression angle θ0 so as to obtain a value to be used as a geomagnetism depression angle θ. A second computation unit calculates an azimuth α and an elevation angle β from the second measurement data set h and the geomagnetism depression angle θ. When a plurality of solutions exist, they are stored as candidates (α1, β1) and (α2, β2). A selection unit selects a detection value (α, β) from the candidates (α1, β1) and (α2, β2) with reference to the above-described values α0 and β0 serving as reference values.

摘要： A magnetic sensor comprises magnetoresistive elements and permanent magnet films, which are combined together to form GMR elements formed on a quartz substrate having a square shape, wherein the permanent magnet films are paired and connected to both ends of the magnetoresistive elements, so that an X-axis magnetic sensor and a Y-axis magnetic sensor are realized by adequately arranging the GMR elements relative to the four sides of the quartz substrate. Herein, the magnetization direction of the pinned layer of the magnetoresistive element forms a prescribed angle of 45° relative to the longitudinal direction of the magnetoresistive element or relative to the magnetization direction of the permanent magnet film. Thus, it is possible to reliably suppress offset variations of bridge connections of the GMR elements even when an intense magnetic field is applied; and it is therefore possible to noticeably improve the resistant characteristics to an intense magnetic field.

摘要： A magnetic sensor 10 includes GMR elements 11-18, and heating coils 21-24 serving as heat generating elements. The elements 11-14 and 15-18 are bridge-interconnected to constitute X-axis and Y-axis sensors, respectively. The heating coils 21, 22, 23, and 24 are disposed adjacent to the elements 11 and 12, the elements 13 and 14, the elements 15 and 16, and the elements 17 and 18, respectively. The heating coils 21-24, when electrically energized, heat mainly the adjacent elements. Therefore, the elements can be heated and cooled in a short period of time in which constant geomagnetism can be ensured. Data for compensation of temperature-dependent characteristic (ratio of change in sensor output value to variation in element temperature) is obtained on the basis of the temperatures of the elements before and after the heating, and the magnetic sensor outputs before and after the heating. Subsequently, the temperature characteristics of the elements are compensated on the basis of the data.

摘要： Data are input from a geomagnetic sensor that detects magnetic fields in three axial directions, and magnetic field data are measured on the basis of the input data. The measured magnetic field data are sequentially stored, and a determination is made as to whether a plurality of the magnetic field data thus stored lie within a same plane in a three-dimensional orientation space. When it has been determined that the plurality of the magnetic field data lie within the same plane in the three-dimensional orientation space, center coordinates of a circular arc where the stored magnetic field data lie are calculated, as provisional offset values, on the basis of the magnetic field data and in accordance with a predetermined algorithm. Magnetic field data measured after the calculation of the provisional offset values is corrected with the provisional offset values, and an arithmetic operation is performed for determining orientation data on the basis of the corrected magnetic field data.
