    摘要： A magnetic apparatus for detecting a position of a vehicle, capable of detecting a lateral deviating distance of a vehicle over a lateral deviation width with a high accuracy and at a high speed, wherein a magnetic field component in the direction of advance of the vehicle is detected; or more preferably a three dimensional magnetic sensor (1), which comprises a magnetic sensor element for the direction of advance of the vehicle, and magnetic sensor elements for two directions crossing the first-mentioned direction and provided additionally, is used, whereby it becomes possible to heighten a center retaining capability of the vehicle, widen a lateral deviating distance detecting range around four times from around 25 cm to around 1 m, and detect a magnetic marker (3) reliably even when disturbance magnetic field exerts influence upon this detection operation to thereby start center side guidance reliably.

    摘要： The aim of the present invention is to offer a keeper for a dental magnetic attachment that is strong, has low manufacturing costs, and is not easily detached from the tooth root. The keeper proposed herein has a keeper body, which is shaped like a plate, and a root, which is attached to the bottom of the keeper body. The keeper body and the root are machined from a single piece of soft magnetic material in one piece. The root has a smaller diameter part that is linked to a larger diameter part whose external diameter is larger than an external diameter of the smaller diameter part. The smaller diameter part is linked to the bottom of the keeper. There are multiple circumferential grooves around the outer side of the larger diameter part.

    摘要： A denture attachment including a magnet body, to be embedded in a denture base, comprises a pair of soft magnetic alloy end plates, a non-magnetic alloy spacer disposed between the end plates, and a cap covering the magnet body, the end plates and the spacer except on the side of a coping. The attachment causes a magnetic attractive force of the magnet body to act on the coping of a soft magnetic alloy embedded in a pulp cavity of a tooth deprived of the crown, whereby the denture base is stabilized on gingiva. The magnet body is disposed with its N and S poles facing the end plates, respectively.
