Title: Constant flow valve
Inventor: YOKOYAMA IKUO
IPC: F16K17/30
Filed: 1989-09-30
Abstract: PURPOSE:To expand a flow control range by providing a opening section whose diameter become small from the upper stream to down stream, a cylinder capable of abutting on the valve seat section of the opening section, a valve needle forming an orifice between the opening section and itself, and a plurality of springs each spring constant of which is different from each other for urging the cylinder to separate from a valve needle opening section. CONSTITUTION:When fluid passes through an orifice 11, a pressure difference is generated in the down stream, and a valve 13 moves toward an opening section 7 pressingly urging a spring 14 or both springs 14 and 15, or away from the opening section 7 receiving elastic resiliency from the spring 14 or both springs 14 and 15 according to the extent of the pressure difference. Along this motion the orifice 11 is made to be expanded or reduced, and even if the upper and down stream side pressure of a valve needle body is fluctuated, a flow rate is automatically controlled to become a set flow rate. When a cylinder 10 is moved to the way from the opening section 7, the valve needle 13 is also moved resulting in the expansion of the orifice 11 and increase in controlled flow rate value. When the cylinder 10 is made to move toward the opening section 10, controlled flow rate value become small. If the cylinder 10 is made to move further, it becomes closedown state.

Filed: 1986-10-24
Abstract: PURPOSE:To stablly execute a ghost image elimination by executing the elimination by using the vertical synchronizing signal of a television signal in case no ghost image eliminating reference signals are detected by a ghost image eliminating signal detection means. CONSTITUTION:The ghost image eliminating reference signal detection circuit 1 detects whether or not a ghost image eliminating reference signal is superposed in the vertical flyback cycle of a television signal, and outputs its result to an error detection circuit 4. The error detection circuit 4, in case said superposition of a ghost image eliminating reference signal is detected, detects error signals due to a ghost image by using the ghost image eliminating reference signlas, but in case said superposition is not detected, detects error signals due to a ghost image by using the leading edge of a vertical synchronizing signal.
