摘要： A phase comparison circuit for generating control voltages for a number of varactors of a phase locked loop (PLL) circuit has been disclosed. According to a particular embodiment, a number of phase difference detection circuits (101, 102 and 103) can be successively activated in response to a set of activation signals to generate output voltage signals (Vtunei). Output voltage signals (Vtunei) can vary according to an elapsed period time, and thus represent a phase difference. Each phase difference detection circuit (101, 102 and 103) can activate a trigger signal (Trg) when an internal voltage signal equals a predetermined value. A main signal (SIG) can be input as an activation signal to a first stage phase difference detection circuit (101). A trigger signal from a first stage phase difference detection circuit (101) can be input as an activation signal to a subsequent stage phase difference detection circuit (102). Phase difference detection circuits (101, 102 and 103) can be deactivated in response to an output signal (out) generated in response to a reference signal (REF), and provide output voltages (Vtunei) which can represent a phase difference between reference signal (REF) and a main signal (SIG).

摘要： A gasification power generation system includes: a gasifying section for allowing a fuel, such as coal, to react with a gasifying agent, such as air, to produce a gasified product gas; a power-generating section for generating electricity using energy obtained by burning the gasified product gas, which is produced by the gasifying section; and a preheating section for preheating the gasifying agent supplied to the gasifying section, to a self ignition temperature of, e.g., about 1000° C. The preheating section raises the temperature of air supplied into the gasifying section, to a high temperature of about 1000° C. when a fossil fuel, such as coal, is used as the fuel. Thus, it is possible to achieve gasification power generation with a high generating efficiency using inexpensive, simple constructions and to realize a stable and low NOx combustion of the gasified product gas.
