Title: Vertical contour correction circuit
Inventor: MIYAJIMA HIROYUKI
IPC: H04N9/68
Filed: 1987-03-30
Abstract: PURPOSE:To prevent glittering on the screen by integrating a vertical contour signal so as to obtain a vertical profile component output picture in the screen and controlling the gain in a variable gain amplifier circuit in response to the value, suppressing the correction as the vertical contour component output picture is more in the pattern. CONSTITUTION:When a switching diode 183 is reset, the correction quantity voltage (that is, a DC voltage) outputted to a variable amplifier circuit 13 is divided an output of a variable DC power supply 14 and outputted to an emitter follower by a transistor 184. In varying the output voltage of the variable DC power supply 14 by using an external adjustment knob, the gain in the variable gain amplifier circuit 13 is changed and the amplitude of the vertical profile signal (j) is changed to control the correction of the vertical contour correction. Moreover, the correction control circuit 18 suppresses the correction as the vertical contour component output picture is more in the pattern. Thus, the flittered pattern is prevented and natural vertical contour correction is applied.

Further, even when pressurized under a fully closed condition, the resilient sealing member 2 will not move. Therefore, the sealing member 2 can provide a repulsive resiliency enough to seal a high- pressure of fluid.
