摘要： A test mode circuit for a memory device for, in a test mode, transforming information to be stored in the memory device and information being read from the memory device and selecting simultaneously information stored in cell arrays in the memory device, so as to grasp interferences between adjacent cells and between adjacent data bus lines. The circuit comprises a cell array section having a plurality of cell arrays for storing input data therein, a first switching section for selecting one of test and normal modes and selecting one of the plurality of cell arrays in the normal mode, a first logic section for transferring desired information simultaneously to the cell array section in response to a clock signal in the test mode, a second logic section responsive to the clock signal for outputting directly output data signals from the plurality of cell arrays or inverting the data signals and outputting the inverted data signals, a third logic section for, in the test mode, inputting output signals from the second logic section and discriminating whether the data signals from the plurality of cell arrays are the same, and a second switching section for selecting, as its output signal, an output, signal from the third logic section in the test mode and the data signal from the selected one of cell arrays in the normal mode.

摘要： A digital arithmetic logic unit in which the carry chain is subdivided into a series of bit fields allowing independent and simultaneous data manipulation to be undertaken in each of the bit fields. Division of the carry chain is achieved via a carry chain selector consisting of a series of multiplexers, one being placed between each pair of adjacent stages of the carry chain. Each multiplexer has two data inputs, one of which forms the carry to the next stage of the carry chain. The carry selected either continues the computation or defines the end of one bit field and provides the least significant carry-in bit to the next bit field. This selection of the carry by the multiplexer is under control of a programmable register, thus allowing variable division of the carry chain.

摘要： A tracking apparatus for a VCR comprises an operational amplifier comparator for comparing a reference voltage with an integrated drum rotation pulse signal. First and second switches are provided to respectively increase and decrease the value of the reference voltage applied to the operational amplifier comparator to respectively decrease and increase the width of a pulse signal produced by the comparator and input to a monostable multivibrator which controls the positioning of a video head relative to an advancing track of a scanned video tape. In this way, tracking adjustment can be performed by remote control and does not depend on the use of variable resistors usually present for the purpose of volume control.

摘要： When a speed change occurs during a reproduction mode of a VCR, an analog video signal is developed that has a width determined by synchronizing the analog video signal to a point in time when an electrical potential for the head switching signal is shifted. The analog video signal is applied as a compensating signal to video signals so that a rising level is compensated for near a forced synchronizing signal. Thereby, a condition is provided for the forced synchronizing signal to be reliably detected without being effected by noise signals corresponding to the forced synchronizing signal in order to produce a stable picture.
