    摘要： The invention relates to a compact, noncontact rotary position sensor that accurately detects a rotary position of a rotating object. A magnetism throttling portion (16, 17) is provided in a midway point of a magnetic path. Two magnetic induction elements (21, 22) are disposed adjacently each other at the magnetism throttling portion (16, 17). This arrangement effectively allows a magnetic flux to converge at the location, at which the magnetic induction elements (21, 22) are mounted. A noncontact rotary position sensor offering high sensitivity and high accuracy can then be obtained. It is also possible to simplify routing of signal lines from the two magnetic induction elements (21, 22), since the two magnetic induction elements (21, 22) are adjacent to each other.

    摘要： A rotational position sensor having a compact and simple structure, in which a magnetic surface can be formed to have a more accurate shape, and an electronically controlled throttle device for an internal combustion engine, which employs the rotational position sensor. The rotational position sensor comprises a pair of substantially half disk-shaped magnetic cores (1, 2) disposed in an opposed relation to each other with a magnetic sensitive device interposed therebetween, a pair of substantially arc-shaped magnetic cores (41-47, 51-57) disposed in an opposed relation to each other along outer peripheries of the half disk-shaped magnetic cores (1, 2), and a permanent magnet (21, 22) fixed in contact with at least one of the arc-shaped magnetic cores (41-47, 51-57). Magnetic flux generating from the permanent magnet flows successively through one of the arc-shaped magnetic cores (41-47, 51-57), the half disk-shaped magnetic cores (1, 2), and the other of the arc-shaped magnetic cores (1, 2), followed by returning to the permanent magnet (21, 22). The half disk-shaped magnetic cores (1, 2) or the permanent magnet (21, 22) is rotatable, and the magnetic sensitive device detects an amount of the magnetic flux varying with rotation of the half disk-shaped magnetic cores (1, 2) or the permanent magnet (21, 22).

    摘要： A non-contact sensor for sensing a rotational position of a rotating object is provided. A ring-shaped permanent magnet (10) magnetized in the axial direction is sandwiched between two pairs of magnetic plates (11, 12, 13, 14) from above and below. Two pairs of upper and lower protruded magnetic substance portions (16, 17, 18, 19) are provided between the upper and lower magnetic plates (11, 12, 13, 14) at opposite outer ends thereof. Magnetic sensitive devices (21, 22) are inserted in air gaps between the two pairs of upper and lower protruded magnetic substance portions (16, 17, 18, 19). A magnetic flux generated from the ring-shaped permanent magnet (10) is substantially concentrated to the protruded magnetic substance portions (16, 17, 18, 19) and passes the magnetic sensitive devices (21, 22). The amount of magnetic flux passing each magnetic sensitive device (21, 22) is substantially proportional to the rotational angle of the ring-shaped permanent magnet (10). The rotational position of the ring-shaped permanent magnet (10) and hence the rotational position of a rotating shaft (15) supporting the ring-shaped permanent magnet (10) can be sensed in a non-contact manner as a signal output from the magnetic sensitive device. Since the magnetic flux is effectively concentrated to positions where magnetic sensitive devices (21, 22) are attached, a non-contact rotational position sensor having high accuracy and high sensitivity can be obtained.

    摘要： The invention relates to a non-contact type rotational position sensor. A rotor (31) (a permanent magnet) is mounted on a rotational shaft (40). A Hall IC (6) is interposed between an upper stator (4) and a lower stator (2) which are magnetic plates. The Hall IC (6) is sensitive to magnetic flux density which varies according to a rotational position of the rotor (31). In a housing (1) incorporating the rotor (31) and the Hall IC (6) is provided integrally a connector (7) provided with an external connection terminal. Conductors (7) for connecting external connection terminals and input/output terminals of the Hall IC (6) are embedded into the housing (1) by insert-molding. One ends of conductors (7) are exposed at a fixed position where the input/output terminals are present. The terminals of the Hall IC (6) are guided by a guide (10) and joined to the one ends of conductors (7).
