摘要： A first objective lens and a second objective lens are fixedly mounted on a lens holder. The lens holder has four magnetic members embedded in a side thereof about an axis of rotation. The magnetic members are associated with coils respectively. The lens holder is rotatable supported by a support which has four permanent magnets fixedly mounted on a side thereof corresponding to the four coils. A pair of the magnets located opposite to each other is for the focusing control and the other pair of the magnets located opposite to each other is for the tracking control and the objective lens switching control. When the coils corresponding to the magnets are loaded with a switching signal, they turns the lens holder to switch the objective lenses from one to the other. When the coils corresponding to the magnets are loaded with a tracking drive signal, they perform the tracking control. When the coils corresponding to the magnets are loaded with a focusing drive signal, they perform the focusing control. At the beginning of operation, the objective lens drive apparatus can be initialized by feeding the switching signal to either pair of the coils so that the objective lens is set across a light path.

摘要： An optical disk drive which is a data recording device or a data reproducing device having two movable members. The first movable member has two objective lenses on it. A magnetic circuit is secured to the second movable member to apply a magnetic field to the tracking coil attached to the first movable member. The first and second movable members can rotate around a shaft. The first objective lens or the second objective lens is selected and used in accordance with the type of the disk used. The device can therefore record data on or reproduce data from disk of different types. Further, since the angle at which the second movable member is inclined to the shaft remains unchanged, the device can record data on or reproduce data from a disk, without causing coma-aberration or the like, no matter whether the first object lens or the second objective lens is selected and used.

摘要： An electronic apparatus capable of displaying linked pages in turn by an easy operation for users is provided. In a element in an SMIL document, the attribute ??dur=t is added to URI description for specifying a media element. The resulting notation implies that a file name placed before ?? indicates a designated page and a link destination of the designated page is displayed. A numerical value following dur= indicates the duration for which a given link contained in the designated page can be activated. An SMIL player interprets an SMIL document having such a description, so as to allow auto-linking to the link destinations of the designated page with the defined link intervals.

摘要： In an apparatus for moving an objective lens, the objective lens (2) mounted on a lens support is suspended on a support frame by tracking leaf springs (6) and focusing leaf springs (8), each of the tracking leaf springs (6) and each of the focusing leaf springs (8) being coupled to each other. Focusing (26a) and tracking (26b) coils are provided on the lens support and are arranged in a magnetic circuit fixed to the support frame. The support frame is movably supported on side rails and coupled to a linear motor mechanism (28). In a long-stroke access, the support frame is moved in a access signal by the linear motor mechanism along a radial direction of an optical disk. In a middle-stroke access or a tracking operation, the magnetic circuit is energized in response to the access signal or a focusing signal so that the tracking leaf spring (6) is deformed by an interaction force between a current supplied to the tracking coils (26b) and magnetic fluxes generated from the magnetic circuit. Thus, the objective lens (2) is moved along the radial direction of the disk within a middle-stroke range. In a focusing operation, the magnetic circuit is energized in response to a focusing signal so that the focusing leaf spring (8) is deformed by the interaction force. Thus, the objective lens is moved along its optical axis.

摘要： A picture signal processing system includes a playback apparatus and a display apparatus connected via first and second communication units. The playback apparatus receives a video signal made up of source data generated by moving giant image data in a constant direction at a constant speed, wherein the giant image data has a number of pixels far greater than the number of pixels in a display region. The playback apparatus reads source data speed information stored in the video signal header, and transmits the video signal and the speed information to the display apparatus. The display apparatus references a table to determine how to process the video signal on the basis of the speed information, processes the video signal, and then displays the processed video signal.
