Title: Single pll system applied to video signal
Inventor: OTSU KIYOHISA
IPC: H04N5/94
Filed: 1994-05-15
Abstract: PURPOSE:To allow a single PLL to sufficiently compensate a dropout and a phase jump by generating an equivalent synchronizing signal at a position corresponding to a time window when a synchronizing signal is not in existence within a period designated by the time window in the lock state. CONSTITUTION:A synchronizing signal selector 4 outputs a signal ssync being a signal csync passed without any modified processing in the non-lock state. In this case, since no hold signal is set, a synchronizing signal passing window generator 3 outputs a signal fcomp and a time window signal at an interval resulting from a frequency-dividing a signal vclk of a frequency. A phase comparator 5 compares the phase of the signal ssync with that of the signal fcomp at their trailing points and its output is used to control the frequency of a VCO 1 through an LPF 6. When the synchronizing signal is not in existence in the period of the time window, the signal ssync is forcibly fallen down at the trailing edge of the time window signal to compensate a dropout.

Title: Ventilation control method of automobile tunnel
Inventor: NAGAOKA NORIO
IPC: E21F1/00
Filed: 1978-10-12
Abstract: PURPOSE: To accomplish effective and stable ventilation by enabling ventilation control according to the traffic conditions.  
     CONSTITUTION: The smoke permeation rate VI 5 in the tunnel is converted to 4W 20m A and inputted to an arithmetic device 9 to average VI value per second every 5 minutes. likewise, CO value 6 is converted to 4W20m A and inputted to an arithmetic device 9 to average the CO value per second every 5 minutes. An average of the VI and CO values is obtained every 30 minutes to determine the number of output notches 11W15. A comparison is made between the output notch thus determined and the output notch of an on-going pinboard and if the output notch of the arithmetic device 9 is larger than that of the pinboard, alternation is made to the output notch of the arithmetic device 9 to increase the ventilation volume. With such an arrangement, the pinboard can be corrected every 30 minutes thereby enabling effective adjustment to the traffic conditions.

Title: Magnetic recording, reading and reproduction system
Inventor: YOSHIDA YUUJI
IPC: G11B5/02
Filed: 1978-10-12
Abstract: PURPOSE:To suppress an error interval due to a drop-out phenomenon to a minimum by alternating a read output signal, obtained by one magnetic head, with that by the other through a delay circuit when the level of the former decreases below a fixed value. CONSTITUTION:Magnetic head 2 scans the same track lagging magnetic head 1. Now, if a drop-out phenomenon is caused and a read output signal from head 1 decreases in level below a fixed value, an output from amplification sense circuit 6 operates signal change-over circuit 7 to connect the input to the side of head 2 by switching. A read output signal from head 2 is passed through signal delay circuit 5 for an adjustment to the same phase as the output signal from head 1. Namely, the output of variable frequency oscillation circuit 8 maintains the same oscillation frequency as a frequency before the occurrence of the drop-out. The correct demodulation of a magnetic recording signal can therefore be secured by demodulation circuit 9 synchronizing with the output from head 1.
