    摘要: A portable phone has a CPU and a magnetic sensor unit including an X-axis magnetic sensor, a Y-axis magnetic sensor, and a temperature sensor. CPU measures at first and second temperatures the influence of a magnetic field of permanent magnets upon an output Sx of the X-axis magnetic sensor and an output Sy of the Y-axis magnetic sensor, and stores the influence data together with the first and second temperature data. CPU estimates at the present temperature the influence upon the output Sx of the X-axis magnetic sensor and the output Sy of the Y-axis magnetic sensor, from the present temperature detected with the temperature sensor and the stored influence data. CPU corrects the outputs Sx and Sy in accordance with the estimated influence and determines the direction of the portable phone from the corrected outputs Sx and Sy.

    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 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: In an apparatus for sorting articles on hangers, a chain pushes articles along an elongated guide rail. The guide rail has a series of gaps, each of which is normally bridged by a pivoted sorting member. At an open gap, the articles are diverted to a horizontal transfer apparatus comprising a rotatable, disc-shaped, article-receiving member. The receiving member conveys articles to the upper end of a downwardly inclined sorting chute. A ridge-shaped, arcuate guide extends along a portion of the perimeter of each receiving member to prevent articles from falling off the receiving member. The horizontal transfer apparatus enable the chutes to be positioned laterally away from the guide rail so that they do not interfere with movement of hangers having horizontal shoulders.
