摘要:
A fuel-air premixing device of a gas turbine has a double-cylinder structure composed of an inner cylinder and an outer cylinder defining therebetween flow passages such that a fuel is supplied into air flowing through the passages so that a pre-mixture of the fuel and air is formed and discharged. The premixing device further has a plurality of radially spaced fuel nozzles capable of supplying the fuel into the passages, and fuel supply rate regulator valves for independently controlling the rates of supply of the fuel from the radially spaced nozzles.

A combustor of a gas turbine having a plurality of liners defining combustion chambers, and transition pieces adapted to rectify the flow of the combustion gas discharged from the liners before the combustion gas is introduced to the turbine. A guide plate is disposed in the gap between each pair of adjacent transition pieces near the gas outlets of the latter so as to guide the flow of air to the radially outer surfaces of adjacent transition pieces, thereby to improve the cooling of these surfaces and, at the same time, to mechanically connect the adjacent transition pieces to suppress the vibration of the transition pieces.

A gas turbine includes a cooling air supply device for supplying compressed cooling air to moving blades, and a heat exchanger provided in the cooling air supply device for cooling the compressed cooling air. Compressed air withdrawn at an intermediate-stage portion of a compressor is used as a cooling medium for the heat exchanger. With this construction, the moving blades can be sufficiently cooled without the use of any special cooling medium.

A premixing swirling burner including a burner body having a swirling member at one end for causing fuel introduced into the burner body to flow in vortical form through the swirling member, a burner outer frame mounting the burner body and communicated with an air line for introducing air into the burner body, and a cylindrical member located in the burner outer frame for enclosing the burner body, with an air passage being defined between the inner periphery of the cylindrical member and an outer periphery of a portion of the burner body. A premixing chamber is defined between an outer periphery of a central portion of the burner body and an inner periphery of the cylindrical member for providing a fuel-air premix flowing toward the swirling member. A fuel chamber introduces fuel into the interior of the burner body, and a fuel ejection nozzle is located along an outer surface of the central portion of the burner body. A channel defined between the inner periphery of an end portion of the cylindrical member and an outer peripheral portion of the burner body formed an inlet for the premixing chamber has a cross-sectional area smaller than a cross-sectional area of the air passage.

A pressure sensor includes a surface sheet whose front side is an operating surface and a substrate sheet that includes a plurality of switches and that is disposed below the back side of the surface sheet at a predetermined space therebetween. When the operating surface is depressed, the surface sheet is deformed toward the substrate sheet and a switch of the plurality of switches is turned into an input state, and a resolution of a switch signal from each of the switches varies in accordance with the amount of a pressing force applied on the operating surface. Therefore, an electronic device, such as a cellular phone, installed with the pressure sensor can have various functions realized by a variation in the resolution.
摘要:
A polymer injection molding unit is disclosed having a mold wall which includes a portion made of an infrared transmissible material which is radiated by an external infrared radiation source. Due to the passage of the infrared radiation through the infrared transmissible material, the infrared radiation is not absorbed by the mold wall and the mold wall is not substantially heated. The infrared radiation passes through the mold wall and is absorbed by the molten polymer material near the mold wall. As a result, the temperature of the molten polymer material rises and its viscosity is lowered to thereby enhance the shape transcription of complicated or fine shapes present on the mold wall, without increasing the temperature of the mold wall.

There is disclosed a semiconductor memory device comprising memory cells (M11 to Mmn) for storing binary data, and first reference cells (DM11 to DMm1) and second reference cells (DM12 to DMm2) corresponding to respective two storage states of the memory cell, to make comparisons between the storage state of the memory cell and the storage states of the both reference cells at first and second sense amplifiers (1, 2) to compare outputs from the both sense amplifiers at the third sense amplifier (3) to thereby detect storage data of the memory cell. Thus, there can be provided a high speed memory device which has a less number of memory cells and of a high integration structure, and which has a little possibility of an erroneous operation in reading.
