    Abstract: PURPOSE:To obtain the small scale of time division exchange in which real time response having a service function such as information offer is guaranteed by providing a unified memory having a time switch section and a data storage section, a write address storage section and a read address storage section. CONSTITUTION:The unified memory 1 consists of a time switch section 1a and a storage section 1b, a data from each terminal equipment is inputted from an incoming line 2 and a data to each terminal equipment is outputted to an outgoing line 3. The data is transmitted synchronously with a time slot counter 4. A data is written in a read address storage section 5 by a control section 6 comprised of a CPU, a ROM and a RAM and the content of a write address storage section 9 is rewritten by the control section 6. In addition to the exchange operation using a time switch being the fundamental function of the exchange, the write of a voice data and digital data from a terminal equipment to the storage section 1b of the unified memory 1 and the transmission of a data in the storage section 1b to the terminal equipment are executed.

    Abstract: PURPOSE:To enable to identify sensibly the wear of magnetic tape, by reproducing the magnetic tape on which the signal of almost constant amplitude is recorded, detecting the peak value of reproduced signal sequentially, and adding the number of detections at each peak value. CONSTITUTION:When the reproduction of one magnetic tape 1 is finished, the number of productions by each peak value is stored in the memory 9 as to all the reproduction signals S obtained from the start to the end of reproduction of this magnetic tape 1. In this case, 256 types of peak values can be obtained by using the memory 9 having 32 bits per one word and 256 words. The number of productions up to 32 bits can be counted as to one peal value. That is, 2 =4.3X10 counts can be made as to one peak value. The memory 9 storing the data is read out in the adder of address and the distribution of production of peak value can be displayed by adding this data to the plotter.

    Abstract: PURPOSE:To record the depth of dropout by a method wherein, after a crest value is adjusted by an A-D converter, the lowest value is detected by comparing the values with a comparator and written in a register. CONSTITUTION:A signal having a certain amplitude is recorded in a magnetic tape 1 and, if there is any dropout, the envelope of the crest value of a regenerative signal S drops to the bottom level. The crest value Vi adjusted through A-D convertor 5 is compared 7 with the specified value VTH. When Vi Vi-i, the output of the comparator 8 turns to become ''1'', and the register 9 maintains that content. In addition, when the dropout is terminated, permitting Vi>VTH, the depth of the dropout value maintained in the register 9 is transferred to a memory 12 and recorded therein.

    Abstract: PURPOSE:To enable a reliable detection of a minute time change in a signal amplitude, such as drop out, by a method wherein a variable thereshold in decided by multifying an average value at every given period of an input digital signal with a given coefficient to compare it with the median of the given period. CONSTITUTION:A regerative output produced by means of a magnetic head 3 passes through an A/D transducer 6, and forms an average value at every given period by means of N/2-stage shift registers 8, 9 a substractor 7, an accumulator 12, and a 1/N divider 13. The average value is multiplied with a coefficient k(

    Abstract: PROBLEM TO BE SOLVED: To reduce a test cost when the load test of an apparatus used to supply electric power to a load is performed.
    SOLUTION: The regenerative load apparatus is provided with a first load 22 by which the supplied electric power is sent out from the side of an output in a current conversion ratio nearly inverse to that of a device 21 to be tested, a second load 23 which consumes the supplied electric power and a power supply 24 by which electric power nearly equal to the consumed electric power at the second load 23 is supplied to the device 21 to be tested. The electric power is branched into the first load 22 and the second load 23 so as to be supplied from the device 21 to be tested, and the electric power which is sent out from the second load 22 is supplied to the device 21 to be tested in addition to the electric power from the power supply 24.
