Title: Method for synchronizing input data signal with clock signal and data system
Inventor: ROBAATO EICHI REONOBUITSUCHI
IPC: H03L7/107
Filed: 1993-08-16
Abstract: PURPOSE: To keep the PLL loop gain almost at a fixed level based on the data transition density of an input data signal. CONSTITUTION: A phase detector 14 forms a feedback loop 12 which includes a charge pump 16 of a loop gain modulator, a loop filter 18 and a VCO 20. A data transition comparator 22 compares the transition of an input data signal VS with that of an output clock VO of the VCO 20 and produces a pulse width modulation control pulse VT. The pulse VT controls the level of a pulse amplitude modulation current pulse IC that is supplied to the filter 18 via the pump 16. At this point, the pulse IC is supplied to the filter 18 in a unique system using both pump 16 and comparator 22. The pulse amplitude is related to the transition density of the signal VS, and the transition density varies as a time function. Accordingly, a PLL dynamically controls the current pulse amplitude. As a result, the loop gain compensates the density variance and is kept at a fixed level.

Filed: 1983-11-25
Abstract: PURPOSE:To recover and utilize efficiently the heat energy of gas while operating smoothly and safely an installation for cleaning blast furnace top gas by providing a heat exchanger between the dust catcher and dry dust removers of a blast furnace top gas system. CONSTITUTION:The high-temp. top gas of a blast furnace 1 passes through a dust catcher 2 and is cleaned by dry dust removers 31-35 and thereafter the gas enters a turbine 4 and drives the turbine to run a generator 5, thereby generating power. Combustible components such as CO are burned in hot stoves 71-73 and after the gas is heated therein, the gas is discharged in the form of low- temp. waste gas through a chimney 8. If the temp. of the furnace top gas is extraordinarily high, the bag filters of the dust removers 31-35 are damaged and therefore the gas is passed through a heat exchanger 9 before entering the dust removers 31-35 to heat the gas emitted from the turbine 4. The gas itself is lowered in temp. and enters the dry dust removers so that the dust is safely removed without damaging the bag filters of the dust removers. The heat energy possessed by the furnace top gas is efficiently recovered.
