Title: Television signal processing method
Inventor: ABE YOSHIO
IPC: H04N7/08
Filed: 1986-08-25
Abstract: PURPOSE:To superimpose much digital signals in the band of an existing TV system by superimposing a multiplex signal modulated by a digital signal to a chrominance subcarrier in a band symmetrical about a residual side band or both bands. CONSTITUTION:A carrier wave P1 obtained from a 1st oscillator 4 is modulated in terms of amplititude by an amplitude modulator 2 by using a video base band signal inputted from a terminal 1. The obtained modulation wave is subjected to band limit by a 1st filter 3 and a residual-side wave is formed and fed to an adder 9. On the other hand, the digital signal inputted from a terminal 6 forms a multiplex signal by applying 4-phase shift keying modulation to a subcarrier P3 obtained from a 2nd oscillator 11 by a 4-phase modulator 12. The multiplex signal applies double-side band amplitude modulation to the carrier P2 obtained by subjecting 90 deg. phase shift 5 to the carrier wave P1 at the modulator 7. The modulated signal is subjected to band limit in a 2nd filter 8 and fed by an adder 9. The video base band signal is superimposed on the multiplex signal at the adder 9 to form a synthesized TV signal.

IPC: B29C55/18
Filed: 1988-08-12
Abstract: PURPOSE:To enable high polymer to be drawn stably and efficiently through economical facilities by carrying out reverse rolling for first directional drawing in installing pinch rolls or tension applying devices in front and the behind of a rolling machine, and drawing through a tenter method for the drawing in a right-angled direction therewith. CONSTITUTION:In installing pinch rolls 3, 3' or tension applying devices in front and the behind of a rolling machine 2, reverse rolling is performed while being applied with tension. After extruding, a material is cut into a predetermined length, and heated then in a heating furnace 1, after that, rolling is conducted. Elastic reversion is decreased by the tension, and it becomes possible to perform stable rolling. At this occasion, the material temperature lowering due to the prolongation of rolling times is permitted because the material thickness is relatively large. In the next place, the drawing in a right-angled direction in subsequence requires about 2 at an ordinary drawing rate, however, a tenter method 4 is employed as a drawing method. The tenter method 4 is of a type that the material may be bound by clip-shaped grasping devices by its end parts, and drawn continuously in the width direction.
