Abstract: PURPOSE:To prevent occurrence of an important fault in advance by stopping the drive power supply to an electronic function block other than a video monitor function block on the occurrence of a fault of forced cooling function and giving alarm display onto the video monitor function block for the occurrence of the fault. CONSTITUTION:A fault detection means 5 detects a fault state of a forced cooling function 3 provided to a composite video monitor 10 and gives a detection output to a control means 6. Then on the occurrence of a fault of the forced cooling function, the control means 6, based on the detection output by the fault detection means 5, stops the supply of the drive power supply 4 to electronic function blocks other than the video monitor function block 2 and the occurrence of the fault of the forced cooling function is subject to alarm display by the video monitor function block 2. Thus, the sure operation of various incorporated function blocks is ensured and the occurrence of important fault such as baking of the equipment main body or a fire is prevented in advance to secure the safety.

Abstract: PURPOSE: To always obtain a stable color/black-white discriminating signal by supplying the detection signal to a comparator having a hysteresis from a detecting circuit to use the output of the detecting circuit as a color/black-white discriminating signal and at the same time controlling an attenuator.
CONSTITUTION: When the levels of color signals R-Y/B-Y are reduced down to L
b , the output potential of a rectifying/smoothing circuit 7 is higher than the threshold level TH
2 . As a result, a comparator 8 is set in a black-white mode and a signal of a low level "0" is obtained at an output terminal 9 as a color/ black-white discriminating signal SDIS. In this case, a connection switch 10c of an attenuator 10 is turned on. Therefore the relation between the output potential of the circuit 7 and the levels of signals R-Y/B-Y is shown by broken line B in a figure. At the same time, the threshold level of the comparator 8 is set at TH
1 . Therefore the output potential of the circuit 7 is considerably higher than the level TH
1 . Thus the level "O" is stably kept for the signal SDIS obtained at the terminal 9.

Abstract translation: 目的：通过将检测信号提供给具有来自检测电路的滞后的比较器，以使用检测电路的输出作为彩色/黑白鉴别信号，并且在相同的情况下，总是获得稳定的颜色/黑白鉴别信号 时间控制衰减器。 构成：当彩色信号R-Y / B-Y的电平降低到Lb时，整流/平滑电路7的输出电位高于阈值电平TH2。 结果，将比较器8设置为黑白模式，并且在输出端子9处获得低电平“0”的信号作为彩色/黑白识别信号SDIS。 在这种情况下，衰减器10的连接开关10c导通。 因此，图中用虚线B表示电路7的输出电位与信号R-Y / B-Y的电平之间的关系。 同时，将比较器8的阈值电平设定为TH1。 因此，电路7的输出电位远高于电平TH1。 因此，对于在端子9处获得的信号SDIS，电平“O”被稳定地保持。

Abstract: PURPOSE:To separate a pilot signal securely from an audio signal without influencing the audio signal, by recording the single pilot signal on more than one audio track in an inphase or out-of-phase state in accordance with the kind of a multiple audio signal. CONSTITUTION:A signal obtained by demodulating a multiple audio signal is recorded on more than one audio track, and in accordance with the kind of the multiple audio signal, a single pilot signal is recorded on more than one audio track in an inphase or out-of-phase state. For example, the recording system 10A of a VTR superposes on encoded single-frequency pilot signals Pb and Pc, generated by a generating circuit 20 from the output Pw of a detecting circuit 15 for the multiple control signal, corresponding to the multiple control signal on demodulated audio signals Sb and Sc to record them on audio tracks of a magnetic tape 5. A reproduction system 10B supplies a reproduced control signal Pw' to a generating circuit 40 for the multiple control signal CS, which is generated corresponding to the pilot signals Pb and Pc.

SOLUTION: When an easy G code setup is selected in a menu screen displayed by the input of the menu key 35 of a key 2, the easy G code setup mode start part 7 of a timer control part 6 starts an easy G code setup mode and displays a city name selection screen on a monitor 14 or a fluorescent display tube 15. A city name selection part 8 selects a city name receiving a broadcasting signal on the displayed city name selection screen. A table selection part 9 selects and reads a setup setting value corresponding to the city name which is set by the input of the OK key 36 of the key 2 on a displayed G code reservation content recognition screen from the table of a memory. A television channel setting part 10 sets a television channel number which is selected and read from the table of the memory as the setup setting value.

Abstract: PROBLEM TO BE SOLVED: To perform a cue and a review by pressing only one operation button and also to set a review time according to the user's preference. SOLUTION: When a skip button is once pressed at the time of watching a program under the usual playback(PB) state, the cue state is effected. When the skip button is pressed again after arrival at the point desired to be seen, the cue state is changed over to a review state. Then, after performing a review for a fixed time T1, the PB state is automatically effective again. At the time of the second successive pressing as stated above, if this pressing is kept on as it is, the review is continued during the pressing time. Then, when the skip button is released from its pressing, the review is canceled to become the PB state. The review time T1 can be set according to the user' preference.

Abstract: PURPOSE:To rationally input and output signals regardless of reduction of the number of connectors by switching a line input and the input from a specific device in accordance with switching of a switching means and outputting a signal to the connector of the line input at the time of switching to the input from this specific device. CONSTITUTION:A switching means 15 is switched to position '1', the signal from a second connector 12 is supplied to a signal processing circuit 16; and when the switching means 15 is switched to position '2', the signal from a first connector 11 is supplied to the signal processing circuit 16, and the signal from this circuit 16 is taken out to the second connector 12. Thus, the second connector 12 is rationally used for input and output, and signals are rationally inputted and outputted though the number of connectors is small.

Abstract: PURPOSE:To eliminate an erroneous discrimination on a carrier due to a noise by giving different DC potentials to the positive-phase and negative-phase output voltages of a multiplying circuit for quadrature detection. CONSTITUTION:A control voltage Vin is varied to set an offset voltage between the positive-phase and negative-phase output voltage of the multiplying circuit 4 in various modes. Namely, when the control voltage Vin is between ''0'' and V1, the difference between currents I and J, i.e. offset voltage is constant. When the control voltage is between V1 corresponding to DELTAV and V2, the offset voltage is maximum and an erroneous discrimination 2' is suppressed greatly at this time. Then, when the control voltage is between V2 and Vcc, the offset voltage drops with a gradient corresponding to the resistance value of a resistor 45. Constant current sources 51 and 52 are connected to the emitters of transistors 48 and 49 to stabilize offsets at output terminals 4c and 4d of the multiplying circuit 4.

Abstract translation: 目的：通过给正交检测乘法电路的正相和负相输出电压提供不同的直流电位，消除由于噪声引起的对载波的错误识别。 构成：控制电压Vin变化以在各种模式中设置乘法电路4的正相和负相输出电压之间的偏移电压。 也就是说，当控制电压Vin处于“0”和V1之间时，电流I和J之间的差异即偏移电压是恒定的。 当控制电压在与DELTAV和V2相对应的V1之间时，偏移电压最大，此时大大抑制了错误辨别2'。 然后，当控制电压在V2和Vcc之间时，偏移电压以与电阻器45的电阻值相对应的梯度下降。恒流源51和52连接到晶体管48和49的发射极，以稳定输出端的偏移 乘法电路4的端子4c和4d。
