    摘要: A variable valve device for an internal combustion engine for varying operating characteristics of engine valves by changing a relative rotational phase of a camshaft to a timing sprocket has an electric motor that rotates the camshaft relatively to the timing sprocket, a cover member provided to cover a front end section of the electric motor, and an angle sensor that detects a rotational angle position of a motor output shaft. The angle sensor includes a detected unit provided inside of a top end section of the motor output shaft and a detecting unit provided on the cover member so as to be opposed to the detected unit through a minute clearance. A metal disk-shaped reinforcing plate is molded and fixed inside of a cover main body of the cover member mainly formed of a synthetic resin material, thus enhancing the entire rigidity of the cover main body.

    摘要: In an elevator position detection apparatus, when a first diagnosis switch is closed, a diagnosis coil generates a first induced magnetic field, and when a second diagnosis switch is closed, the diagnosis coil generates a second induced magnetic field that is weaker than the first induced magnetic field. In a constant L output fault diagnosis mode in which the first induced magnetic field is generated, an output value of a measurement signal falls below a threshold regardless of whether or not a detection subject body is present in a detection region. In a constant H output fault diagnosis mode in which generation of both the first and the second induced magnetic fields is stopped, the output value of the measurement signal equals or exceeds the threshold regardless of whether or not the detection subject body is present in the detection region.

    摘要: A robot includes a body and a bumper. The body is movable relative to a surface and includes a first portion of a sensor. The bumper is mounted on the body and movable relative to the body and includes a backing and a second portion of the sensor. The backing is movable relative to the body in response to a force applied to the bumper. The second portion of the sensor is attached to the backing and movable with the backing relative to the first portion of the sensor in response to a force applied to the bumper. The sensor is configured to output an electrical signal in response to a movement of the backing. The electrical signal is proportional to an amount of displacement of the second portion relative to the first portion.

    摘要: There is provided a method for calculating with high accuracy a multi-turn absolute rotation angle of a motor rotating shaft coupled to a motor output shaft. In a rotation angle detection device according to this invention, a rotation angle θn of an n-th rotating shaft satisfies the relationship with a rotation angle θ1 of the motor rotating shaft: θn=(−(m±1)/m)n−1×θ1. The rotation angle detection device as an embodiment of a mechanism satisfying the relationship includes a gear mechanism in which a gear having (m±1) teeth meshes with a gear having m teeth between each adjacent two of first to n-th rotating shafts. A multi-turn rotation angle of the first rotating shaft is expanded to a detected value p1 of the first rotating shaft which is a rotation angle of the first rotating shaft and R0×m0+R1×m1+ . . . Rn−2×mn−2 corresponding to the number of revolutions of the first rotating shaft, coefficients R0 to Rn−2 are obtained on the basis of detected values from angle detectors of the respective shafts, and the multi-turn rotation angle of the first rotating shaft is calculated. Detection errors generated in the angle detectors of the second and subsequent rotating shafts can be effectively reduced, and a high-accuracy multi-turn rotation angle can be calculated.
