    摘要: A data shuffling method for shuffling data for rearranging predetermined data which are contained in a plurality of data units in predetermined numbers each and can be interpolated by using adjoining data in a two-dimensional array comprised of these data units so as to facilitate concealment of data errors occurring during transmission. The method includes the steps of: dividing the two-dimensional array into a plurality of processing units each containing a predetermined number of the data units; establishing correspondence between each of the predetermined data and each serial number indicating the position of each of the predetermined data in each the processing units for every processing unit; calculating for every processing unit each of the sums or differences of each of the serial numbers corresponding to each of the predetermined data with a predetermined coefficient; calculating for every processing unit each of the values of the remainder system of each of the sums or the differences with respect to the maximum value of the serial numbers; and arranging each of the predetermined data corresponding to each of the values of the remainder system at a position in the processing unit indicated by each of the values of the remainder system to shuffle the predetermined data for every processing unit and, a data shuffling apparatus for the same.

    摘要: A de-shuffling circuit of a first audio processor 21 performs the following signal processing. When an audio signal is to be reproduced from a video tape 1 in which an audio signal having 4004 samples in consecutive 5 fields is recorded on a helical track, with the number of effective samples for one field equal to 800 or 801, all samples of at least one reproduction among audio signals produced by two or more reproductions of an image signal of the same field are outputted and samples of other reproductions are adaptively controlled in a variable speed reproduction mode for reproducing an arbitrary field twice or more with a dynamic tracking head 2A. Thus, the total number of samples for the 5 fields is limited to not more than 4004.

    摘要: An electrophotographic printer having a print head which moves in a direction perpendicular to the direction of paper feed. The print head comprises a photosensitive drum, a transfer roller disposed in opposition to the recording paper where it moves over the platen, and a toner image bearing belt passing around the photosensitive drum and passing between the transfer roller and the recording paper over the platen. An electrostatic latent image is formed on the photosensitive drum, and a toner image corresponding to the latent image is formed on the toner image bearing belt. The toner image is transferred to and fixed on the recording paper at the location where the transfer roller presses the toner image bearing belt against the recording paper. The print head is moved for spacing while the transfer and fixing are taking place. The sequence of the toner images transferred to and fixed on the recording paper form a desired print out of one line.

    摘要: An optical head assembly for use with an optical disk apparatus includes a magnetic circuit block having permanent magnets each being elongate in a track traversing direction and a yoke for forming a magnetic circuit which conducts a magnetic field generated by the permanent magnets. The yoke includes a first through hole extending in a focusing direction, magnetic gaps located at opposite sides of the first through hole in the track traversing direction and individually accommodating the permanent magnets, and a second through hole for admitting the light beam issuing in the track traversing direction to guide it to the first through hole. The first through hole and magnetic gaps each has a cross-section relatively long in the track traversing direction. A beam deflector is loosely fitted in the first through hole for deflecting in the focusing direction the light beam which is incident thereto from the second through hole. The beam deflector is supported by a carriage. An objective lens focuses the light beam deflected by the beam deflector in the focusing direction onto the recording medium surface. The objective lens is mounted on a lens holder which is in turn mounted on the carriage movably in the focusing direction. Guide members support the magnetic circuit block and carriage movably in the track traversing direction along the recording medium surface.
