摘要： In an audio mirror speaker, an uneven area is formed on a planar mirror surface and a directivity distribution is controlled by changing a relative position of a diaphragm facing the mirror surface and the mirror. The directivity distribution of such a speaker is determined by a radius of curvature of the uneven area. Since the directivity changes with various movements of the planar mirror, a freedom in setting the directivity distribution is enhanced.

摘要： In an image display method and apparatus for displaying image data, it is determined, based upon a control code contained in received image data, whether the image data is whole image data in one frame or partial image data in one frame. When it is determined that the image data is partial image data, the content of a memory being displayed is transferred to another memory, and the partial image data is stored in the memory which is the destination of the transfer. When the transfer of the data to the memory which is the destination of the transfer ends, the content of this memory is read and displayed.

摘要： An apparatus for reproducing digital information from a recording medium having a plurality of parallel tracks and digital information recorded thereon as n-channel (n being an integer greater than or equal to 2) digital signals. The n-channel digital signals are reproduced by n-reproducing heads. The digital information contained in the reproduced signals is stored in a storage device. Discriminating data is obtained for determining which of the n-channel digital signals reproduced correspond to the reproducing heads. The timing of an access device, accessing the storage device for performing a predetermined processing of the digital signals stored in the storage device relative to the reproducing timing of the digital information reproduced by the n reproducing heads, is controlled in accordance with the discrimination data.

摘要： In an apparatus for recording a data sequence including main binary data of an (m X n) number of bits formed by sampling a main information signal and a plurality of subordinate binary data of also an (m X n) number of bits respectively carrying additional information of varied kinds, recording tracks are formed one after another with data which includes the main binary data representing the main information signal sampled within a given period of time and the plurality of subordinate binary data recorded in each of the tracks; and recording is performed in such a manner that, among the plurality of subordinate binary data, the meaning of information carried by a second n number of bits varies according as the condition of the data varies between a case where l-adic numerical data is arranged to be formed by a first n number of bits within the plurality of subordinate binary data and another case where irregular data is formed there as the l-adic numerical data cannot be formed by the first n number of bits (n and m being integers, respectively, and l being an integer not exceeding 2.sup.n).
