    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: A source program is stored for every line of the source program in a source program memory. Jump commands in the language used in the program are previously stored in a jump command memory for storing jump commands used in the program. The contents of the source program memory are compared with the contents of the jump command memory, the kinds of each commands in the source program are identified, and first and second identification data are produced. The first identification data which are set for each command identifies the kind of each command, and identifies that the execution contents of commands adjacent to each other along the sequence of commands are continuous. The second identification data are set for each jump command and each command to which processing is to be jumped. The first and second identification data are stored in the identification data memory. The process flow of the source program is analyzed based on the contents of the identification data memory in an analyzer. The result of the analysis by the analyser is output in the form of a flowchart.

    摘要: A PCM type record-playback system converts an analog primary signal into a digital signal by sampling and quantizing it and concurrently records it on a magnetic tape with a secondary signal for showing the tape position. The primary and secondary signals are recorded on the same track in a time-divided manner so that recording can be effected with a small number of magnetic heads and the tracks on the magnetic tape can be effectively utilized.
