Abstract: A battery system includes: a battery block defining a cooling gap between battery cells composed of a plurality of rectangular/prismatic cells; and a gas blower forcibly blowing the gas through the gap in the block. The block, set in two separate arrays, is provided therebetween with an intermediate duct connected to each of the gaps. An outer duct is provided outside the block set in two separate arrays, and the plurality of gaps are parallel-connected between the outer duct and the intermediate duct. The gas blower forcibly blows the gas from the intermediate duct to the outer duct, and the gas forcibly blown is branched from the intermediate duct to be blown through each of the gaps to cool the cells. The gas having passed through the gaps and cooled the cells is collected at and exhausted from the outer duct.

Abstract: A battery system includes a battery block, a cooling pipe, and a coolant feeding device. The battery block includes a plurality of rectangular batteries that have a width greater than a thickness and are securely arranged in array alignment by a battery holder. The cooling pipe cools the rectangular batteries of the battery block. The coolant feeding device feeds coolant to the cooling pipe. In the battery system, the cooling pipe is arranged on the surface of the battery block in a thermally-coupled state so that the rectangular batteries are cooled by the coolant, which is circulated through the cooling pipe.

Abstract: The battery pack includes plural battery cells 1, and insulating separators 10 disposed between adjacent battery cells 1, where the plurality of battery cells 1 are disposed in a stacked configuration with a prescribed gap between adjacent battery cells 1. A separator 10 has a plural gas channels that enable the flow of cooling gas. The gas channels have cooling gas entranceways and exit ways, which open at the sides of the battery block formed by the stacked battery cells 1. A separator 10 has cut sections formed to position the entranceways and exit ways of the gas channels inward from the sides of the battery block. This allows cooling gas near entranceways and exit ways to be smoothly introduced to, and exhausted from the gas channels, and reduces cooling gas pressure losses in those regions.

Abstract: A turbine inlet temperature operating section (15) determines the turbine inlet temperature T4 based on the flow rate Gf and temperature Tf of fuel being supplied to a combustor (3) and the flow rate G3 and temperature T3 of air. Based on the turbine inlet temperature T4, a pilot ratio operating section (16) sets a pilot ratio, and a bypass valve operating section (17) and an IGV opening operating section (18) generate a bypass valve control signal and an IGV control signal, respectively.

Abstract: A fuel-flow-rate control device, a power generation system, and a fuel-flow-rate control method which can prevent overshooting of a gas turbine output (gas turbine inlet temperature) and which can improve power generation efficiency are provided. The fuel-flow-rate control device includes a computing portion for obtaining a state quantity relating to operating conditions and temperature conditions of a gas turbine as an input signal and computing a fuel-flow-rate command for controlling a fuel flow rate supplied to a combustor based on the above input signal, and a second selection circuit for setting the above fuel-flow-rate command to be not more than a fuel-flow-rate upper limit. The fuel-flow-rate upper limit is a fuel flow rate at which the gas turbine inlet temperature is set to be not more than a predetermined upper temperature limit.

Abstract: A combustion temperature high speed detection device is provided with a phase lead processing portion, thereby canceling out a detection lag of a temperature detector, and detecting the combustion gas temperature of a combustor at a high speed. The combustion temperature high speed detection device is also provided with a first-order lag filtering portion with a time constant of 0.25 second, a phase lag processing portion with a time constant of 10 seconds, a temperature change filtering portion with a cutoff frequency of 2 to 3 Hz, and a disturbance filtering portion including first-order lag filtering portions with different time constants and a high value selecting portion. Thus, high speed detection of the combustion gas temperature more suitable for a gas turbine system can be performed.

Abstract: A tape dispenser has a housing in which a roll of adhesive tape is rotatably supported, a cutter provided on the front of the housing for cutting the adhesive tape to desired lengths, an adhering member for adhering the tape dispenser to a supporting surface, and both a support rod rotatably mounted to the housing, and a ring-shaped support disposed at an end of the support rod and rotatably supported by the adhering member. Thus, with the adhering member adhering the tape dispenser to a supporting surface, the housing of the tape dispenser can be rotated about the support rod so as to be movable between vertical and horizontal orientations. Also, the housing can be rotated 360.degree. about the adhering member such that the cutter of the tape dispenser can be moved to a desired angular position while the tape dispenser remains adhered to the supporting surface.
