| 20090293478 | CONDENSER AND STEAM TURBINE POWER PLANT - A condenser that restrains fluctuations in the condenser vacuum in a power generating installation. | 12-03-2009 |
| 20110005225 | Electric Power Plant, and Method for Running Electric Power Plant - An electric power plant, e.g., a boiling water reactor nuclear power plant supplies steam generated in a nuclear reactor to a high-pressure turbine and a low-pressure turbine. The steam discharged from the low-pressure turbine is condensed with a condenser. Water generated with the condenser, used as feed water, flows through a feed water pipe, is heated with a low-pressure feed water heater and a high-pressure feed water heater, and then supplied to the nuclear reactor. The steam extracted from the high-pressure turbine is supplied to the high-pressure feed water heater. The steam extracted from the low-pressure turbine is compressed with a steam compressor, and the steam whose temperature has been increased is then supplied to the high-pressure feed water heater. The feed water to be directed to the nuclear reactor is heated in the high-pressure feed water heater by both the steam extracted from the high-pressure turbine and the steam compressed with the steam compressor. Because the feed water is heated by both the extracted steam and the compressed steam in the high-pressure feed water heater, the amount of plant service power consumed by the steam compressor can be reduced. Therefore, it is possible to increase thermal efficiency in the electric power plant when increasing the power output. | 01-13-2011 |
| 20110283704 | Power Plant - A boiling water nuclear power plant supplies steam from a reactor to high-pressure and low-pressure turbines. Water (feed water) generated by condensing steam in a condenser is heated by low-pressure and high-pressure feed water heaters and supplied to the reactor. The steam discharged from the low-pressure turbine is compressed by a steam compression apparatus (a heat pump) and supplied to one of the low-pressure feed water heaters to heat feed water. The steam extracted from the low-pressure turbine is also supplied to the low-pressure feed water heater. When power required for the steam compression apparatus is Q | 11-24-2011 |

| 20090024379 | EVALUATION DEVICE - Evaluation by logic simulation can be favorably performed. A target packet determination part determines if a target packet which is a response packet that is to be transmitted with respect to a request packet that is received is in a simulation result table. When there is a target packet, a response packet output reads out and transmits the target packet from the simulation result table. On the other hand, when there is no target packet, a system controller forces a logic simulator to perform logic simulation regarding the received request packet, disconnects a connection with an opposing connection device, so as to perform reconnection after completion of the logic simulation by the logic simulator. A table generating part writes the request packet and the response packet obtained by the logic simulator into the simulation result table, the request packet and the response packet being made correspondent to each other. | 01-22-2009 |
