摘要： There is provided an angle sensor and angle detection device of high output and high accuracy with a wide operating temperature range. First through eighth sensor units 511, 522, 523, 514, 531, 542, 543 and 534 are produced from spin valve magnetoresistive films that use a self-pinned type ferromagnetic pinned layer comprising two layers of ferromagnetic films that are strongly and anti-ferromagnetically coupled. The respective sensor units are produced via the formation and patterning of thin-films magnetized at angles that differ by 90°, and the formation of insulation films. By using, for the ferromagnetic films, CoFe and FeCo films that have similar Curie temperatures to make the difference in magnetization amount be zero, high immunity to external magnetic fields, a broad adaptive temperature range, and high output are realized.

摘要： A free fall detection device capable of detecting a fall accompanied by rotation is provided. A fall accompanied by rotation is detected based on a waveform of an acceleration signal output from the acceleration detection unit and an angular velocity signal output from the angular velocity detection unit. A gravity center acceleration of the device to be protected is calculated from the acceleration detected by the acceleration detection unit and from the angular velocity detected by the angular velocity detection unit. Even when the device being protected rotates as it falls, the fall of the device can be detected from the detected acceleration or angular velocity. Further, by calculating the gravity center acceleration not affected by the rotation, it is possible to detect a fall of the device with high precision even if the device rotates as it falls.
