摘要:
A transonic blade is provided that operates in a flow field where flow has a transonic speed or higher in an axial-flow rotating machine and that concurrently achieves a reduction in shock loss and in the local stress of the blade.The transonic blade includes a hub cross-sectional surface joined to a rotating shaft or an outer circumferential side casing of a rotating machine; a tip cross-sectional surface located furthest from the hub cross-sectional surface in a spanwise direction which is a vertical direction of the rotating shaft; a leading edge located on an upstream side; and a trailing edge located on a downstream side. At least a part of a passing working fluid flow has a transonic speed or higher. A portion of a stacking line which is a line connecting together respective gravity centers of cross-sectional surfaces located from the hub cross-sectional surface to the tip cross-sectional surface is located on a downstream side of a stacking center in a flow direction of a working fluid main flow.

On a first intermediate layer provided on a substrate and having an excellent surface smoothness, are formed a second intermediate layer and an YBCO superconductor layer having excellent properties. An YBCO superconductor (10) having a critical current density (Jc) of 1 MA/cm2 or higher can be produced by forming a first intermediate layer (2), a second intermediate layer (3), an YBCO superconductor layer (4) and an Ag-stabilized layer (5) on the surface of a tape-shaped biaxially oriented Ni—W alloy substrate (1), wherein the first intermediate layer (2) has a thickness of 5 nm or less, has a surface smoothness, comprises A2Zr2O7, and is formed by repeating coating and provisional burning several times by the MOD method, the second intermediate layer (3) comprises a CeO2 film and is formed by the pulse plating method, the YBCO superconductor layer (4) is formed by the MOD method, and the Ag-stabilized layer (5) is formed on the YBCO superconductor layer (4).

摘要:
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.A portion of working fluid driving the high-pressure turbine is allowed to flow not into the high-pressure turbine but into a low-pressure turbine.

摘要:
The invention is intended to maintain turbine reliability when, based on a gas turbine designed for one desired cycle, a gas turbine for another different cycle is manufactured. A channel of a compressor is formed such that a mass flow of a fluid compressed by the compressor changes. Thus, when manufacturing, based on the gas turbine designed for one desired cycle, the gas turbine for another different cycle, turbine reliability can be maintained.
摘要:
A current to be applied to a ground is defined as the sum of two sinusoidal waves having first and second frequency components. A signal to be used at the time of synchronous detection is defined as a difference between the sinusoidal waves having the first and second frequency components. As a result, a substance in the ground, and the position and depth of the substance can be specified with high accuracy.

A recovery phenomenon in which the concentration of a compound to be measured in soil increases again after reducing the concentration is utilized for changing the distribution state of the compound to be measured in soil, whereby the direction of the high-concentration region of the compound to be measured in soil can be detected.
摘要:
A Coulomb-blockade element includes a silicon layer formed on a substrate through an insulating film. The silicon layer includes a narrow wire portion and first and second electrode portions. The narrow wire portion serves as a conductive island for confining a charge. The first and second electrode portions are formed to be connected to the two ends of the narrow wire portion and are wider than the narrow wire portion. Each of the first and second electrode portions has constrictions on at least one of the upper and lower surfaces thereof, which make a portion near the narrow wire portion thinner than the narrow wire portion.

A hose clamp includes a clamp body having an annular ring part for fastening a hose and a pair of grip parts for filling the role of radially expanding the ring part, and a separately formed holder. The holder is inserted around the pair of grip parts and is capable of retaining the pair of grip parts in a closely adjacent state. The holder is provided integrally with means for removal of the holder from the pair of grip parts retained in the closely adjacent state.
