Patent application numberDescriptionPublished
20090185896GAS TURBINE AND GAS TURBINE COOLING METHOD - A gas turbine includes a nozzle vane and a sealing unit engaged with the nozzle vane inside a turbine supplied with combustion gases produced by mixing and burning air for combustion and fuel. The nozzle vane and the sealing unit are disposed in a channel of the downward flowing combustion gases on the outlet side of a gas path. A plurality of engagement portions between the sealing unit and the nozzle vane are provided successively from the upstream side toward the downstream side in a direction of flow of the combustion gases, and a downstream one of the plurality of engagement portions has a contact interface formed in a direction across a turbine rotary shaft. A reduction in the thermal efficiency of the gas turbine can be suppressed.07-23-2009

20090320438TWO-SHAFT GAS TURBINE - Provided is a two-shaft gas turbine with improved reliability that improves output power and efficiency and is stably operated by establishing a balance between the driving force of a compressor and the output power of a high-pressure turbine in the case where the two-shaft gas turbine is applied to a system in which the flow rate of fluid flowing into a combustor is increased compared with a simple cycle gas turbine.12-31-2009
20100229566TWO-SHAFT GAS TURBINE SYSTEM - Disclosed herein is a highly-reliable two-shaft gas turbine system in which the rotational speed of a compressor exceeds its rated rotational speed when the combustion temperature during rated operation is set to the rated combustion temperature of a simple-cycle gas turbine system and in which the drive force for the compressor can be balanced with the output from a high-pressure turbine without turbine efficiency being compromised.09-16-2010

20120075893INVERTER DEVICE OVERVOLTAGE PROTECTION METHOD - An inverter device overvoltage protection method that can appropriately protect an inverter device from an overvoltage condition is disclosed. When the DC voltage rises, and a DC voltage detection value exceeds a second DC voltage level, a protective circuit stops the inverter device by outputting an inhibit signal to a gate drive circuit, but it is assumed at this time that the rise of the DC voltage is temporary and no error output signal is output to the exterior of the inverter device. However, in the event that the DC voltage rises further while the inverter device is temporarily stopped, and the DC voltage detection value exceeds a first DC voltage level, it is determined that protection of the inverter device is necessary, and an error output signal is output to the exterior of the inverter device.03-29-2012
