Filed: 1989-03-28
Abstract: PURPOSE:To improve the controllability by correcting the feedforward gain in each fixed period according to the difference obtained between the deviation integral value to the mean manipulated integral value to the mean manipulated value of an actual process based on a control rule. CONSTITUTION:The trend data in the actual manipulated variable of a process and the manipulated variable of a feedforward control system 20 are collected.

If the subtraction value exceeds the prescribed range, the present feedforward gain is corrected in each fixed period by a control rule and in accordance with the difference between said two deviation integral values. As a result, the gain of a feedforward model can be automatically controlled to the optimum value.

Next, the decision is made whether the write-in of the track is completed or not, and the process is returned to the initial stage when the write-in is not completed, and this process is finished when the write-in is completed. Thus, the ISRCs are quickly retrieved, and the time to read out the ISRCs from the track is remarkably reduced.

Title: Switching system for transmission signal
Inventor: KUNITSUCHI JIYUNICHI
IPC: H04B1/74
Filed: 1986-03-31
Abstract: PURPOSE:To eliminate the disconnection of a signal and to stably switch a circuit at a high speed by opening a gate provided for a transmission route so as to pass through a signal and operating a transmission signal switch after a preset time passes when the digital signal of an alternative radio circuit is switched to the signal of a current radio circuit. CONSTITUTION:If the current radio circuit TP1 develops fading and a switch control signal is transmitted from a reception terminal station, a switch control part 40 transmits a control signal '1' to open a gate to the control terminal (b) of a gate circuit 21 in the current radio circuit TP1. After t1mus passes, said part 40 transmits the control signal '1' to the control terminal (d) of a switch 31 in a transmission signal switch 30, and gives instructions that a signal line 300 is switched to a signal line 301. After t0mus passes, the part 40 switches the control signal '1' transmitted to the gate circuit 20 of the alternative radio circuit SP to a control signal '2'. Thus the cutting of a signal input never occurs at the time of switching. Therefore an abnormal increase in bit errors and the instantaneous disconnection, both of which are caused by the delay of a circuit switching time due to step out, never occur when fading arises.
