摘要： A variable frequency oscillator comprises an oscillating loop and a variable phase shifter for imparting one of two different phase shifts depending upon the polarities of a DC control voltage to a signal from the oscillating loop. The phase-shifted signal has its amplitude controlled by the amplitude of the control voltage and is combined with the signal in the oscillating loop. The vector sum of the combined signals determines the phase angle of the oscillator signal and hence the frequency thereof.

摘要： A nonvolatile semiconductor memory device includes: a sense amplifier; bit lines coupled to the sense amplifier; memory cell transistors and dummy cell transistors coupled in parallel with the bit lines; and a current generating circuit that supplies a test current to current nodes. Either of the source and the drain of each of the dummy cell transistors is coupled to a bit line and the other is coupled to a current node. In a read operation test, the current generating circuit is activated and then the dummy cell transistors are turned on. The sense amplifier compares the test current passed through a bit line with a reference current and outputs output data corresponding to the result of the comparison.

摘要： A vertical deflection circuit is used in a camera tube in a color television camera in which the camera tube is provided with an optical filter having an optically black part extending in parallel with a beam scanning direction of the camera tube. A vertical deflection circuit comprises a circuit for generating a saw-tooth voltage for vertical deflection, a vertical deflection coil for the camera tube, and a circuit for supplying the saw-tooth voltage thus generated to one end of the vertical deflection coil in DC coupling. Due to temperature fluctuation, a vertical deflection width fluctuates with respect to a position corresponding to a black part of the filter, as a reference.

摘要： In a subcarrier regeneration circuit for color television receivers, a phase detector output is sampled by a signal sample-and-hold circuit and a bias sample-and-hold circuit to develop a voltage between the outputs of the two sample-and-hold circuits to control the frequency of a 3.58 MHz subcarrier generated by a voltage controlled oscillator. The oscillator output is phase shifted by 90.degree. and applied to one input of the phase detector for comparison with a gated color burst. The signal sample-and-hold circuit samples the phase detector output during the interval of the color burst, while the bias sample-and-hold circuit samples the phase detector output during an interval which is substantially equal to the flyback interval minus the color burst interval.

摘要： In a color television receiver adapted to receive a color television signal containing vertical interval reference (VIR) signals, a VIR correction circuit is provided to automatically control the hue and color saturation of the received broadcast signal, which may also be coupled to a video tape recorder of the type in which adjacent field signals are recorded with their respective record tracks being skewed relative to each other to permit elimination of otherwise required guardbands between adjacent field tracks. The recorded video signal is reproduced by mixing adjacent horizontal line signals to reduce crosstalk level. A disabling circuit is provided to disable the VIR correction circuit when the receiver is switched to the output of the video tape recorder in playback mode to prevent false VIR signals due to the mixing from affecting the reproduced colors.
