摘要： A highly accurate displacement sensor using GMR elements (2) for detecting a displacement of a physical quantity such as angle is to be provided wherein a waveform distortion of output voltage is diminished.
There are installed at least two Wheatstone bridge circuits having a predetermined angular offset and each comprising a plurality of GMR elements (2a-2h), the GMR elements (2a-2h) each having a fixed magnetic layer (19) set to a predetermined magnetization direction (13). An AC power supply is use as a power supply of the Wheatstone bridge circuits and a displacement of a physical quantity such as a rotational angle is detected on the basis of AC-modulated outputs from the Wheatstone bridge circuits.
An anisotropic self-bias effect of a free magnetic layer (21) in each GMR element can be diminished and hence it is possible to remedy a waveform distortion of an output signal based on the anisotropic self-bias effect of the free magnetic layer (21).

摘要： The object of the present invention is to provide a controller and a system having a highly reliable fail safe function. An ATP device which generates control data for the two systems from an ATP command speed signal, duplicates the logic unit in the ATP device so as to process each control data, provides at least two CRC data for checking the control data for each system, and changes the CRC data of the opposite logic units or selects one of the two according to the content of a failure detection signal from each of the duplicated logic units. It is realized to check the control data and the operation of each logic circuit and only when all the data, circuits, and elements operate normally, an output signal for controlling the object to be controlled is outputted and when a failure is detected in a part, an output signal is outputted. Therefore, when a failure occurs, a fail safe function for controlling on the safety side is made possible.
