Abstract: A steam turbine plant partially utilizes a hydrocarbon fuel such as an LNG as a fuel to improve the efficiency of the plant. A steam turbine plant includes a boiler, a steam turbine, a feedwater system, and a superheating combustor. The boiler generates steam, and the steam turbine is driven by the steam generated in the boiler. The feedwater system recovers the steam exhausted from the steam turbine and supplies the steam to the boiler as a feedwater. The superheating combustor is provided between the boiler and the steam turbine, wherein fuel originated from hydrocarbon fuel and oxidizer are mixed with the steam generated in the boiler and combusted in the superheating combustor to increase the temperature of the steam.

Abstract: A latent heat accumulation system uses latent heat for air-conditioning. The latent heat accumulation system includes a tank, supplying section, injecting section, drawing section and collecting section. The tank has a liquid storing section for storing Fluorinate (trade name) in the lower portion thereof, storing water which is cooled by ice via a boundary surface with Fluorinate in the middle portion thereof and storing the ice together with the water in the upper portion thereof. The supplying section supplies the water into the liquid storing section. The injecting section injects Fluorinate cooled to a preset temperature into the water stored in the liquid storing section. The drawing section draws out the water which is stored in the liquid storing section and cooled by the ice to the exterior of the tank as an air-conditioning heat accumulation medium. The collecting section collects a mixed fluid of the water and Fluorinate from the lower portion of the liquid storing section.

Abstract: It is aimed at providing an optical receiving apparatus and an optical receiving method, which can assuredly receive and process signal lights having different transmission rates, by a simple and single device. To this end, the signal light received by the present optical receiving apparatus is converted into an electric signal by a light receiving element and thereafter sent to an equalizing amplifier whereby the signal is amplified. The transmission rate of this received signal is detected by a transmission rate detecting part, and a band of the equalizing amplifier is optimally controlled by an equalizing band controlling part, corresponding to the detected transmission rate. In case of adopting a PLL (phase-locked loop) circuit as a clock generating circuit, there is also controlled a band of a loop filter corresponding to the transmission rate detected by the transmission rate detecting part. Thus, there can be obtained an excellent reception characteristics, even when receiving signal lights having different transmission rates.
