Title: Electromagnetic flow control valve
Inventor: ANDOU FUMITAKA
IPC: F16K31/08
Filed: 1981-02-02
Abstract: PURPOSE:To improve vibration-proof and hysteresis-proof properties of the electromagnetic flow control valve by installing two permanent magnets with their same poles face to face, energizing repulsive force of these permanent magnets with a spring and thereby miniaturizing the electromagnetic coil. CONSTITUTION:When the electromagnetic coil 25 is OFF, a movable core 8  above a ball valve 9 is pressed down to close the valve seat 10 due to the difference in forces F5 and F4; where F5 is the resultant force of the repulsive  force F1 between permanent magnets 11, 12 and the force F2 of a spring 13,  and F4 is the pressure difference between the inlet and outlet pressures. When  the electromagnetic coil 25 becomes ON, the movable core 8 is pulled up due to  the attractive force F7 and stops at a certain position determined in proportion  to the imposed voltage, so that an approximately proportional relationship is  established between the imposed voltage and the rate of flow passing through  the valve seat. In addition, with the assistance by the spring 13, the permanent magnets can be miniaturized.

Title: Transmitting stage and receiving stage for high definition television transmission system
Inventor: JIERAARU MARI
IPC: H04N7/169
Filed: 1990-01-29
Abstract: PURPOSE: To reduce the disturbance caused by interference due to scrambling at the time of transmitting picture feature-increased video signals through a transmission line. CONSTITUTION: At the time of transmitting picture feature-increased video signals through a transmission line, the video signals are scrambled. The scrambling process is performed by exchanging the video signals with two signals formed by cutting a signal AB from a picture line at the point M of a random position (address X). Since the scrambled signals are displayed as stray signals and not correlated any more with the original picture having ordinary resolution, the interference between these signals and the original video signals corresponding to ordinary pictures has an incoherent structure and is hardly recognized. Therefore, the disturbing action caused by the interference can be suppressed.
