摘要:
In a magnetic rotor, a rotatable shaft is received through a holder. A positioner is made of a magnetic material and is fitted into at least one of an outer peripheral wall of the rotatable shaft and an inner peripheral wall of the holder to position the holder relative to the rotatable shaft in a circumferential direction. An annular magnet is fixed to the holder and surrounds the rotatable shaft. The annular magnet has two magnetic poles of different polarities, which are magnetized in a magnetization direction that coincides with a radial direction of the annular magnet. The positioner is displaced around a rotational axis of the rotatable shaft from the magnetization direction of the annular magnet by about 90 degrees in the circumferential direction.

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.

A magnetizing coil generates a magnetic field to magnetize a magnet in a magnetizing area, in which a direction of the magnetic field is generally parallel to a magnetization direction of the magnet. A magnetizing yoke holds the magnet and is made of a magnetic material, which exhibits a magnetic potential that is generally equal to a magnetic potential of the magnet in the magnetic field at time of magnetizing the magnet. The magnetizing yoke and the magnet substantially fill a projected area of the magnet in the magnetizing area on each of first and second sides of the magnet that are opposite from each other in the magnetization direction of the magnet in the magnetizing area.

Provided is a content editing apparatus which, while selecting and deselecting a plurality of contents, edits the plurality of contents such that selected contents are appropriately associated with each other so as to be simultaneously reproduced. Moving image shooting information which identifies a shooting time of a moving image content, individual shooting information which indicates shooting times of a plurality of other contents, and the moving image content, are acquired. The moving image content is reproduced and displayed. A moving image shooting time corresponding to the moving image content is outputted based on the moving image shooting information, and such individual shooting information that an individual time indicated by the individual shooting information is within a predetermined time period including the outputted moving image shooting time, is retrieved. When the individual shooting information is retrieved, the reproduction of the moving image content is paused, and a user is made select whether or not an other content, which corresponds to each of the retrieved individual shooting information, is to be displayed in link with the moving image content. An other content selected to be displayed in link is acquired, and stored in association with the moving image content, together with information indicating a time for a link display.

In an object selecting apparatus for allowing a user to select an object in a video image: when the object sought to be selected by the user moves, the user selects the desired object intuitively and without feeling uncomfortable; an input operation from the user is received and anticipated paths of the respective objects are estimated based on path information occurring during the certain period of time prior to a point in time which is the start of a predetermined period of time before a time of receipt; and an appropriate object is determined as the object selected by the user when the anticipated position on the anticipated path, which corresponds to the time of receipt, is close to an inputted position.
