    • In an angle detection device for a rotational body, an external peripheral surface of an arc-shaped fluorescent fiber is scanned by a scanning beam from a scanning mirror fixed to the rotational shaft of a swing motor. Fluorescence is generated at a position in the fluorescent fiber scanned by the scanning beam, the fluorescence is propagated to both ends thereof, and the received luminous energy corresponding to the scanning position is detected by photodiodes. A signal processing circuit compares output signals of the photodiodes to obtain the scanning position of the scanning light, and the corresponding rotation angle of the swing motor is found.

    • In a linear actuator (1), on the inside of a rectangular tubular movable element (3), a linear guide (14) that supports the movable element (3) so as to be linearly movable is positioned at a center of the movable element (3), and a position detecting mechanism (20) and load attaching member (13) that sandwich the linear guide are disposed linearly in a vertical direction. This arrangement enables a center of gravity of the movable element (3) to be matched with a center of the linear guide (14). A magnetic circuit is in a bilaterally symmetrical relationship with regard to the center of the movable element (3). Therefore, a center of a thrust force that acts upon the movable element (3) is matched with the center of the movable element (3). The center of the thrust force that acts upon the movable element (3), the center of gravity of the movable element (3), and the center of the linear guide (14) are positioned at the center of the movable element (3). Resistance to sliding in the movable element (3) can be reduced without unreasonable stress being placing on the linear guide (14). Therefore, a magnetically driven linear actuator that has highly precise positioning and that is durable can be realized.

    • In a hall element resolver (10), a pair of hall elements (13, 23) are placed so as to generate detection signals, which include a phase difference of 90 degrees and are sine-curved, when a rotary magnetic drum magnetized with two poles rotates. Meanwhile, supplied as control currents Ic1 and Ic2 for driving the hall elements (13, 23) are alternate electric currents, which include a phase difference of 90 degrees and have the identical frequency, and balanced modulation signals, which include a phase difference of 90 degrees and are sine-curved, are output from the hall elements (13, 23) as detection signals VH1 and VH2. Then, a rotational position is calculated according to the balanced modulation signals. Thus, it is possible by using the hall elements to obtain detection signals which have resistance to a noise, and with which a transmission distance can be lengthened, as it is done by using a resolver.
