IPC: H04N7/08
Filed: 1991-04-24
Abstract: PURPOSE:To attain transmission of even a moving picture without crosstalk by using an FIR filter whose time is unchanged so as to apply 3-dimensional band-limit to additional information and a multiplex signal when a transmission line for an NTSC signal is used to send the additional information and the multiplex signal. CONSTITUTION:A Y signal is given to a luminance signal separation filter 2, in which the signal is separated into a horizontal low frequency, medium frequency, high frequency and a vertical high frequency component. The low frequency component is subjected to band limit by a VT filter 3 to prevent loopback distortion by an interlace subsample distortion. The vertical and horizontal high frequency components are subject to VT filters 6, 10 respectively to prevent crosstalk with the luminance signal due to a spread signal component in the case of a moving picture. The horizontal medium component is subjected to band limit by a VT filter 13 to prevent a crosstalk between a multiplex signal and a chroma signal due to a spread of the signal component in the case of the moving picture. I, Q signals are subjected to band limit by horizontal LPFs 18, 20. A VT filter 22 applies band limit to the signals to prevent crosstalk with a luminance signal.

IPC: F02M51/06
Filed: 1983-05-27
Abstract: PURPOSE:To increase the response and improve the durability of the valve by a method wherein a hard non-magnetic ring is engaged forcibly with the circumference of a fixed iron core and the end face of the ring is projected than the end face of the fixed iron core so that only the projecting face of the ring contacts with the end face of valve body of a movable iron core. CONSTITUTION:When the valve body 23, connected integrally to the movable iron core 22 upon electromagnetic attraction, is abutted against the non-magnetic ring 40, engaged forcibly with the circumference of the fixed iron core 14 and the end face thereof is projected than the end face of the fixed iron core, a gap G is produced between the fixed iron core 14 and the movable iron core 22. The movable iron core 22 will never contact with the end face of a coil assembly in the whole surface thereof and, as a result, the remanence thereof is reduced. According to this method, hydraulic attracting force between the movable iron core 22 and the fixed iron cores 14, 15 is weakened. On the other hand, direct repeated collisions between magnetic bodies such as the movable and fixed iron cores may be precluded by the ring 40.
