Abstract: PURPOSE:To draw out sufficient current without increasing a current value by selecting a pair of input signals by a pair of switching transistors(TRs) and supplying the selected input signals respectively to the bases of TRs whose emitters are used in common and a pair of buffer TRs. CONSTITUTION:The input signals from terminals 1, 2 are selected by the switching TRs 5, 6 and supplied to the bases of the TRs 7-10 whose emitters are used in common. A level down TR 11 is connected to the emitters of the buffer TRs 7, 8 and a low current source 12 is connected to the cathode of the TR 11. The input signals supplied to the bases of the TRs 9, 10 are outputted as a push-pull type output by connecting a TR 13 with reverse polarity to the common emitter. When the voltage of a control terminal 3 is set up to its 'H' level and a terminal 4 is set up to its 'L' level, a signal level-downed by VBE from the input signal inputted to the terminal 2 is outputted from an output terminal 14. When the voltage of the terminal 3 is set up to 'L' and the terminal 4 is set up to 'H', a signal level-downed by VBE from the input signal applied to the terminal 1 is similarly outputted from the terminal 14. Thereby, current can be drawn out without increasing a current value.

Filed: 1986-12-12
Abstract: PURPOSE:To display a white drawn picture by switching an output signal of a modulation means when a luminance signal outputted from an image pickup means is below the threshold level so as not output the signal thereby adding only a simple circuit to use a prescribed monochromic color as a background. CONSTITUTION:Changeover switches 21a-21d output a color signal being an output signal of a modulator 11 when the luminance signal outputted from image pickup means 1, 2 is a prescribed threshold level or over and do not output a color signal when the luminance signal outputted from the image pickup means 1, 2 is below the threshold level. For example, when the signal of the white background picture is processed, the color television signal of the monochromic background picture of a prescribed color is outputted corresponding to the luminance signal outputted from the polarity inversion means via the voltage decrease means and the color difference signal generated by the voltage generating means. Thus, the picture such as picture or character is displayed in white color white using the monochromic picture as the background other than white or black color by adding only a simple circuit.
