    摘要: An audio visual system includes an audio cassette tape player, a central processor unit, a TV screen for displaying a desired pattern in accordance with a data derived from the audio cassette tape player, and a speaker system for providing audio announcement in accordance with information derived from the audio cassette tape player. The audio visual system displays a problem and five typical answers thereto. The student introduces his answer through a keyboard unit. When, for example, an answer key 3 is actuated, the audio visual system drives the audio cassette tape player to locate a commentary suited for response to the actuation of the answer key 3 whereby the commentary associated with answer key 3 is displayed and announced.

    摘要: Audio sound data (compressed data) read by an optical pickup is temporarily held in a memory and the audio sound data is expanded to be returned to its original size. At the time of usual reproduction, since the difference in data transfer rates of reading by optical pickup and data expansion is absorbed, writing and reading of audio sound data are alternately performed using part of the memory capacity, while audio sound data is held by a fixed amount for data protection upon impact occurrence utilizing the remaining memory capacity. At the time of track jump, for example, if the moving distance of a head is long, all the memory capacity is used for data protection. If the moving distance of the head is short, part of the memory capacity is allocated according to the moving time, and the remaining memory capacity is used for data protection upon impact occurrence.

An image pick-up apparatus in which the control gain for restoring the rotating lens barrel to a reference position is increased by static detection of a housing, thereby attaining a compatibility between a high vibration-proofing performance and a high-accuracy origin restoration. A motion vector detection apparatus, in which by making the motion vector detection area movable, a motion vector is detected without any feeling of disorder regardless of the image pattern. An image swing correction apparatus is also disclosed in which the phase of a read clock of a video memory is adjusted in accordance with the result of detection of a time-base error of the video signal, and read out by a clock of regular intervals. The time base of the video signal is thus corrected while at the same time moving the read position of the video memory in accordance with the result of detection of the swing amount of the whole image, thereby correcting the swing of the whole image.

    摘要: Upon initiation of reproduction of data from a disc, the operation of writing into a buffer memory data reproduced from the disc and the operation of reading out data from the buffer memory are carried out in parallel because the buffer memory is first empty. When the data amount in the buffer memory becomes full, a pickup is kicked back from the last reproduction sector by n tracks corresponding to the data amount of L sectors and the data writing operation into the buffer memory is suspended. When the reproduction sector reaches a target sector, data writing is reinitiated, and data of L sectors is written continuously until the buffer memory becomes full.

    摘要: An optical information reading apparatus for reading recorded information by detecting the presence or absence of pits on an optical disk using a laser beam. The laser beam converged a lens irradiates the optical disk in the form of light spots when in the in-focus state. A dividing line of a holographic grating used for detecting offset of the lens from the in-focus state and a dividing line of a photosensitive detector receiving a light diffracted by the holographic grating are adapted to as to be parallel to a radial direction of the optical disk. Therefore, when a light spot formed on the optical disk by astigmatism of the lens assumes an elliptical shape, the light spot becomes an ellipse whose long axis extends to the direction of the dividing line of the photosensitive detector, so that no error signal is generated in the in-focus state.
