Title: Method for controlling flow rate of gas to be blown to refining furnace
Inventor: YAMANE AKIRA
IPC: F27B3/22
Filed: 1985-06-10
Abstract: PURPOSE:To speed up the rise and fall of the flow rate of gas and to improve a transient response characteristic in the stage of changing considerably the flow rate of the gas to be blown by opening or closing fully a flow rate control valve then changing over the flow rate to a target set value and controlling the flow rate to a constant rate. CONSTITUTION:The gas A past the flow rate control valve 16a is blown through a tuyere 12 into a converter 10 at the flow rate controlled to the set flow rate value. A change over circuit 24A changes over the opening degree of the flow rate control valve 16a to the full opening or the opening degree approximate to the full opening by the signal from an opening degree controller 26. Then the back pressure of the tuyere increases and therefore the pressure increase is detected by a pressure gage 20. The circuit 24a changes over the flow rate to the set flow rate value after the changes and a flow rate controller 22A controls the flow rate to a constant rate by the changes set opening degree of the valve 16A. The valve 16A is changed over to the full closing or the opening degree approximate to the full closing by the similar operation and thereafter the opening degree is returned to the changed set opening degree and the constant flow rate control is executed.

Title: Digital pll circuit
Inventor: BABA MITSUO
IPC: H03L7/08
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain the digital PLL circuit which secures excellent reception characteristics by doubling the internal circuit plane of the digital PLL circuit and alternately processing burstlike data signals at a request to narrow down the burst intervals of burstlike data signals. SOLUTION: In the double-plane digital PLL circuit, received burstlike data signals which are different in phase and variation quantity of jitter and duty cycle distortion by bursts are distributed alternately to an internal circuit 0-plane 2 and an internal circuit 1-plane 3 to perform phase synchronizing operation and data discriminating operation. Processing time for the phase synchronizing operation and data discriminating operation for the burstlike data signals in the digital PLL circuit are normally needed, but the processes of the burstlike data signals may overlap with each other because of the two planes and a process wait state can be eliminated. Consequently, the intervals of the burstlike data signals can be made narrow without spoiling the reception characteristics.
