摘要： A position sensor includes a longitudinally extending permanent magnet member at least two longitudinally extending arc-shaped projecting elements respectively projecting from the opposite ends toward the inside space to confront each other at a distance and a pair of compatible main magnetic sensors disposed in the inside space along the longitudinal axis at an interval so as to generate a pair of output signals when the permanent magnet member shifts along the longitudinal axis. The opposite ends of the permanent magnet member are configured to surround a common inside space and polarized to have opposite magnetic poles so as to provide in the inside space a magnetic field whose magnetic flux density becomes a maximum at a longitudinal center of the inside space and gradually becomes smaller as a position of the inside space shifts from the longitudinal center along a longitudinal axis of the permanent magnet members. The arc-shaped projecting elements are arranged so that the magnetic flux density and each of the output signals can be expressed by a cosine of a shift value from the longitudinal center, and the interval is ¼ of the cycle of the cosine.

摘要： A stroke sensor has two magnets, which are magnetized in a cross-section direction and are displaced in a longitudinal direction, and two magnetism sensitive sections arranged parallel to the longitudinal direction. The magnets have circular-arc-shaped swelling end edges respectively and are magnetized such that the swelling end edges have opposite polarities. Thus, a distribution of a magnetic flux density on an arrangement axis substantially coincides with a sine curve. The magnetic flux having such the distribution is displaced in the longitudinal direction together with the magnets. The magnetism sensitive sections are arranged on the arrangement axis to be distant from each other by a distance of one fourth of a cycle of the sine curve. Thus, the stroke sensor that is not affected by temperature and that has high sensing accuracy can be provided.

摘要： An electromechanical conversion device includes an electromechanical conversion unit and a cable, which has a signal wire and a ground wire for grounding the electromechanical conversion unit. The electromechanical conversion unit performs a conversion between a relative movement with respect to a magnetic field generation unit and electrical signals, based on a magnetic field generated by the magnetic field generation unit. The signal wire is connected with the electromechanical conversion unit to transfer the electrical signals, and has a first branch portion and a second branch portion which extend substantially parallel to the ground wire and are respectively arranged at two opposite sides of the ground wire. A distance between the first branch portion and the ground wire is substantially equal to that between the second branch portion and the ground wire.

摘要： An improved rotation angle detecting device that detects a rotation angle of a first member relative to a second member is proposed. The rotation angle detecting device includes a magnet unit fixed to the first member and a pair of magnetic sensors fixed to the second member to provide output signals whose phase is different from each other at 90 degrees in angle. The magnet unit includes a pair of disk plates that has the same magnetic poles at the same circumferential positions and is disposed at a prescribed axial distance and a shaft that is made of magnetic material to support the disk plates at the center thereof. The magnetic unit provides a uniform magnetic field in a space around the shaft between the pair of disk plates, and a pair of magnetic sensors is disposed in the space.
