    摘要： A magnetic recording medium is disclosed which is comprised of a support base having positioned thereon a magnetic layer having a ferromagnetic powder dispersed in a binder composition. The binder composition is comprised of a vinyl chloride-vinyl alcohol copolymer in an amount of 40 wt % to about 95 wt %. The copolymer contains 1 wt % to less than 8 wt % of vinyl alcohol component and 0 to 2 wt % of vinyl acetate component. By using the binder composition which includes the copolymer the resulting magnetic recording medium have excellent surface smoothness, good dispersion of ferromagnetic powder, excellent electromagnetic properties, as well as excellent running property and durability.

    摘要： A microprogrammed control apparatus includes a first control store for providing a first sequence of microinstructions and a second control store which includes first and second control store portions providing first and second sets, respectively, of microinstructions. A selection circuit selects a first microinstruction from the first control store followed by a first set of subsequent microinstructions from the second control store portion, etc. A second selection circuit will select either the selected microinstruction from the first selection circuit or control information provided from a control store. The address for reading out the microinstructions from the first and second control store portions is determined in accordance with the branch address field of the microinstruction currently being executed.

    摘要： Apparatus for maintaining a constant linear velocity for a PCM disc record which includes a detector for optically detecting the PCM signal on the record and supplies the output to a differentiating circuit and a rectifier circuit with the output of the rectifier circuit supplied to a peak detector circuit which supplies its output to a level comparator that also receives a reference level from a reference source. A first phase comparator also receives the output of the rectifier circuit and controls a voltage controlled oscillator through a low pass filter and the output of the voltage controlled oscillator is supplied to the phase comparator. A divider receives the output of the voltage controlled oscillator and supplies a first input to a phase comparator which also receives an input from a reference frequency generator. The outputs of the level comparator and the phase comparator are supplied to the motor drive circuit which controls the drive motor for the disc record.
