Filed: 1982-08-19
Abstract: PURPOSE:To facilitate increasing the capacity of a gas turbine, by a method wherein a fuel and liquid air are simultaneously injected into a combustion chamber, are mixed and brought into combustion, and the resultant high-pressure high-temperature gas is used as a driving fluid for a gas turbine. CONSTITUTION:Air taken in from the atmosphere through an air intake port 1 is liquefied by an air liquefier 8. Since liquid air is rapidly expanded through evaporation when the temperature thereof exceeds the boiling point thereof, when liquid air discharged from the liquefier 8 into the combustion chamber 4 is injected as it is in the liquid state and is brought into combustion by mixing with a fuel injected into the chamber 4 through a fuel nozzle 3, not only the expansion through evaporation due to the combustion of the fuel but also the rapid expansion due to evaporation of liquid air occur simultaneously, a gas of an extremely high pressure can be obtained, whereby the gas turbine is driven. Since liquid air deprives heat of evaporation of 50kcal/kg when being evaporated, the temperature the combustion gas becomes lower than that in a conventional case by about 1,000 deg.C. Accordingly, increasing of the capacity of the gas turbine is facilitated.

Filed: 1989-06-05
Abstract: PURPOSE:To form an excellent reproduction picture without flicker even at the pickup under a fluorescent light source by providing a means generating a white balance control signal based on a level detection output from a level detection means. CONSTITUTION:Capacitor means C1-C3 connecting to a resistor means 18 connecting to an input terminal of a level detection means are switched timewise by a timing signal obtained through frequency division of a vertical synchronizing signal. Thus, the series connection of the resistor means 18 and the capacitor means C1-C3 receiving each of 3 primary color signals obtained by fetching directly a lighting light of an object, that is, a time constant means differs timewise. That is, each of the 3 primary color signals obtained by fetching directly the light of the object is integrated by a different time constant means for each time. As a result, the 3 primary color signals are integrated dividedly timewise and averaged for a time each. Thus, flicker is prevented.
