Abstract: A colour video signal detector which detects the colour level and the colour phase of a colour bar video signal comprises a differentiating circuit (1) that differentiates a color video signal to detect edges in the colour video signal, a switching IC (5) that holds values of the colour video signal at times after a given time interval from the edges and a microcomputer (10) that measures the extracted values of the colour video signal. The differentiating circuit 10 is used for synchronising the colour video sampling to edges in a colour bar signal and allows a seven or eight colour bar signal to be correctly regulated.

Abstract: A receiver receives a digital signal from an external device by digital signal receiver means or receives an analog signal from an external device by analog signal receiver means. Output means outputs the received digital or analog signal, together with graphics information for operating the external device from generation means if necessary. No matter whether an external device supplies a digital or analog signal, the signal and graphics information may serve to operate an external device, thus facilitating control of an external device.

Abstract: PROBLEM TO BE SOLVED: To display an image with high quality by compensating dispersion and a secular change of a cathode ray tube or the like so as to keep a lightness of a screen constant. SOLUTION: A video signal S11 via a variable gain amplifier circuit 11 with a variable resistor RV for contrast control and a current detection pulse P13 from a pulse generating circuit 13 are fed to a mixer circuit 12 and an output of the mixer circuit 12 is fed to a cathode ray tube 17 through a current detection circuit 16. A cathode current in a cathode ray tube 17 detected by a detection circuit 16 based on the detected pulse is compared with a specified value in a storage circuit 19 by a comparator circuit 18. A new mixer circuit 21 is inserted between the variable resistor RV and the variable gain amplifier circuit 11, and an output signal S18 of the comparator circuit 18 and a contrast control signal Srv are fed to the variable gain amplifier circuit 11 through the mixer circuit 21 to control the gain of the variable gain amplifier circuit 11 thereby making the cathode current of the cathode ray tube 17 in matching with the specified current.

Abstract: PURPOSE: To accurately detect a cathode current by detecting and clamping a leakage current flowing to a cathode. CONSTITUTION: At a timing when a scanning line scans the outside of the valid screen of a CRT 1, control pulses for inhibiting electronic beams from flowing from the cathode 2 to an anode 6 are impressed to grids 4 and 5. At the time, a signal output circuit 15 impresses leakage current detection pulses to the base of a PNP transistor 12. Then, the leakage current to the cathode 2 and a bias current supplied through a resistor 11 are made to flow to the resistor 13. Also, a voltage applied to the resistor 13 is inputted to a clamping circuit 20 and the clamping circuit 20 clamps the voltage corresponding to the current made to flow to the resistor 13 at the time to 0V.

Abstract: PURPOSE:To provide the color signal demodulator of the SECAM system in which stable demodulation processing is implemented at all times. CONSTITUTION:A color signal of the SECAM system frequency-modulated is demodulated by a demodulation circuit 12 able to adjust the demodulation frequency. A blanking insert circuit 14 inserts a blanking pulse to the color signal demodulated by the demodulation circuit 12, the color signal with the blanking pulse inserted thereto is outputted as the demodulation signal, a level of the blanking pulse included in the demodulation signal is compared with a demodulation level of a non-modulation carrier included in the demodulation signal, and the demodulation frequency of the demodulation circuit 12 is adjusted to eliminate the level difference through the comparison.

Abstract: PROBLEM TO BE SOLVED: To allow circuit devices which have different source voltage to perform two-way communicate without using switching signal. SOLUTION: A circuit device 1 connected to a 3.3 V power terminal 10 and a circuit device 2 connected to 5 V power terminal 20 are arranged and input/output terminals 11 and 21 are arranged respectively. To those input/output terminals 11 and 21, open-drain output circuits 13 and 23 and input circuits 15 and 25 which make voltage decisions are connected. Then the input/output terminals 11 and 21 are connected through the source and drain terminals (controlled terminal) of, for example, an N type JFET 31 as a two-way element. The source and drain terminal of the JFET 31 are connected to the power terminals 10 and 20 on the sides where the respective terminals are connected via respective resistors 41 and 51. Further, the gate terminals (control terminal) of the JFETs 31 and 32 are grounded and the load voltage characteristic of the element is about -1.5 V.
