|20140290079||MULTI-TURN ABSOLUTE ROTATION ANGLE DETECTION DEVICE AND METHOD OF DETECTING ABSOLUTE ROTATION ANGLE - This detection device is configured from a gear mechanism (||10-02-2014|
|20140172932||DEVICE AND METHOD FOR CALCULATING ABSOLUTE AMOUNT OF DISPLACEMENT, AND METHOD FOR SAME - Some embodiments address a problem of detecting the absolute amount of displacement of a moving body. In various embodiments, the multi-turn absolute angle of rotation of a main shaft is calculated from a rotation angle detected by an angle sensor joined to the main shaft and a countershaft. The rotation of a main shaft (||06-19-2014|
|20140015384||ABSOLUTE ENCODER DEVICE AND MOTOR - The present invention provides an absolute encoder device, including: a permanent magnet including a first magnetic pattern (bipolar) and a second magnetic pattern (multipolar); a first magnetic sensor for detecting a magnetic field of the first magnetic pattern; a second magnetic sensor for detecting a magnetic field of the second magnetic pattern; and a signal processing circuit for calculating an absolute rotation angle of a rotation shaft based on output signals of the first and second magnetic sensors. The first and second magnetic sensors and the signal processing circuit are fixed to a single substrate. The first magnetic pattern is formed on a plane extending in a direction crossing an axial direction inside the permanent magnet, and the second magnetic pattern is formed on an outer peripheral surface of the permanent magnet.||01-16-2014|
