摘要： A method and apparatus for transmission of data among computers or peripherals along a loop transmission line includes a master system which provides signals along the transmission line for establishing a series of data frames of equivalent length. Each data frame is assigned a frame number, and is allotted a preselected amount of available space for placement of data. Subsequent computers or peripherals are preprogramed with a series of frame numbers which identify those data frames into which they may write data, or from which data is to be read. The allotment of preselected frame numbers for placement and reception of data by the respective devices provides for equivalent sharing of the available data transmission capability of the loop transmission system.

摘要： A binary digitizing system which is effective when it is desired to reproduce a picture having a half-tone level with use of, for example, a dot printer or the like. Binary threshold data for comparison with a current picture signal is randomly changed slightly within a predetermined range to such an extent that users cannot recognize change in the level of the binary threshold data, thus preventing the continuation of such regular binary pattern. Further, the binary threshold data for comparison with a current input picture signal is changed according to a desired density to obtain a binary picture signal corresponding to the desired density.
