Title: Color television camera
Inventor: KARATO YOSHITERU
IPC: H04N9/093
Filed: 1989-12-13
Abstract: PURPOSE:To suppress the variance of a focusing voltage by taking out only the focusing voltage component from a deflected saw tooth wave voltage and applying it to a focusing voltage control circuit so that it is negatively fed back. CONSTITUTION:When the potential of the large-amplitude deflected saw tooth wave voltage is varied, it is detected by focusing voltage detecting circuits 19, 20, 21, and 22 and is compared with an external reference voltage, which is applied to a terminal 23, by a focusing voltage comparing amplifier 18, and the voltage of this error is amplified. The amplified error voltage is equally supplied to bases of transistors 5 and 6 in the same direction through focusing voltage coupling resistances 15, 16, and 17 so that a focusing voltage control circuit loop forms a negative feedback path. Thus, the focusing error voltage is suppressed in this focusing voltage control circuit 11 and the focusing voltage always coincides with the external reference voltage, and the stable focusing voltage is applied to an image pickup tube.

Title: Signal transmission interface circuit
Inventor: SEKI SHINSUKE
IPC: H03K19/003
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To suppress reduction of the L and H level noise margins due to the fluctuations of ground potential and power voltage of both receiving and transmitting IC circuits by giving the ground potential and power voltage equal to those of the transmitting IC circuit to the negative and positive polarity power input terminals of the receiving IC circuit by means of a ground potential/power voltage correction circuit. SOLUTION: The potential EL (=VGa) that is equal to the ground potential VGa of a ground terminal Ga of a transmitting IC circuit 3 is given to a ground terminal Gb of a receiving IC circuit 5 via a ground potential correction circuit 8. At the same time, the voltage (=Ea) that is equal to the power voltage Ea of the circuit 3 is given to a positive polarity power input terminal of the circuit 5 via a power voltage correction circuit 7. Therefore, no difference of ground potential and power voltage is caused between both circuits 3 and 5 despite the fluctuations of the ground potential VGa and VGb and power voltage Ea and Eb of the electronic units 1 and 2. Thus, the reduction of the L and H level noise margins can be suppressed.
