Title: Serial component video signal transmission system
Inventor: FURUKI TSUNEO
IPC: H04N11/24
Filed: 1986-01-08
Abstract: PURPOSE:To allow a digital comb-line filter to separate a luminance signal component and a color difference signal one by alternately repeating the level inversion and non level inversion of a luminance signal component at every horizontal scan period and transmitting it. CONSTITUTION:A signal reproduced by a recording and reproducing device 15 is FM-demodulated by an FM demodulator circuit 16. An unnecessary high frequency component arising at the time of FM demodulation is removed by a low-pass filter 17, AD-converted by an AD converter 18 and supplied to the digital comb-line filter 19. When it comes to a signal whose luminance signal component is level-inverted at every 1H, the frequencies of an inverted luminance signal and uninverted one employ fH/2 (fH: one horizontal scan frequency) as basic frequencies. Thus a video signal is constructed of fH, 2fH, 3fH... frequency components and fH/2, 3fH/2, 5fH/2... frequency components (odd-degree high frequency components). Accordingly the digital comb-line filter 19 can clearly separate color difference signal components C at frequencies fH, 2fH, 3fH... and luminance signal components Y at frequencies fH/2, 3fH/2, 5fH/2....

Title: Pole deciding method for process control
Inventor: OTA TOKUJI
IPC: G05B13/02
Filed: 1990-01-12
Abstract: PURPOSE:To improve the conformity and to prevent the hunting by detecting successively three poles to compare the amplitudes of the adjacent poles with each other and discriminating these poles as the genuine ones when the differ ence between adjacent poles is larger than the prescribed value. CONSTITUTION:A control part 2 detects a process variable out of a process 1 and sends an operating function Y to the process 1 based on the variable X to carry out the feedback control. An unstabilization discrimination means 3 monitors both variables X and Y and judges the occurrence of hunting of a control system consisting of the process 1 and the part 2. This discrimination result V is sent to a control parameter control part 4. The part 4 sends a command W to the part 2 to change the control parameter of the part 2 as long as the part 2 is performing the ID control. Thus the control parameter is changed so that the occurrence of hunting is prevented. Furthermore a discrimination parameter setting part 5 sets various parameters U which are needed for the means 3 to detect the hunting.
