Abstract: The thermal load testing device of the present invention makes it possible to produce a large temperature differential between a surface and an interior of a test piece while applying a load to the test piece. A thermal load testing device (1) includes a load applying portion (2) that applies a load to a tubular test piece (10) in an axial line (O) direction, the tubular test piece (10) having a hollow portion (11) that extends along the axial line (O); a cooling fluid supplying portion (3) that causes a cooling fluid to flow through the hollow portion (11); and an infrared image furnace (4) that heats the test piece (10) by a plurality of infrared sources (42) disposed so as to surround the test piece (10) from a whole region in a circumferential direction.

Abstract: A retainer that protrudes from an inner shroud of a vane to a radially inner side and extends in a circumferential direction is formed with an opening that passes through the retainer in an axial direction and defines a space through which air flows. A width of the opening in the circumferential direction is wider than a width of a vane body in the circumferential direction at a radially inner end of the vane body at a position of the retainer in the axial direction.

Abstract: An erosion test apparatus includes a combustor configured to obtain a combustion gas by mixing and combusting compressed air and a fuel, and an erodent supply unit configured to supply an erodent to the combustion gas. The erosion test apparatus further includes an accommodation support unit configured to accommodate and support a test piece having a front surface coated through thermal barrier coating, and an accelerator configured to accelerate the combustion gas including the erodent to collide with the test piece.

Abstract: A process for producing a thermal barrier coating having an excellent thermal barrier effect and superior durability to thermal cycling. Also, a turbine member having a thermal barrier coating that has been formed using the production process, and a gas turbine. The process for producing a thermal barrier coating includes: forming a metal bonding layer (12) on a heat-resistant alloy substrate (11), and forming a ceramic layer (13) on the metal bonding layer (12) by thermal spraying of thermal spray particles having a particle size distribution in which the 10% cumulative particle size is not less than 30 ?m and not more than 100 ?m.

Abstract: A thermal barrier coating material that exhibits superior high-temperature crystal stability to YSZ, as well as a high degree of toughness and an excellent thermal barrier effect. Also provided are a thermal barrier coating, which has a ceramic layer formed using the thermal barrier coating material and exhibits excellent durability to heat cycling, and a turbine member and a gas turbine which are each provided with the thermal barrier coating. The thermal barrier coating material comprises mainly ZrO2 which contains Yb2O3 and Sm2O3 as stabilizers, wherein the amount of the stabilizers is not less than 2 mol % and not more than 7 mol %, and the amount of the Sm2O3 is not less than 0.1 mol % and not more than 2.5 mol %.

Abstract: An automatic analyzer using a reaction vessels of disposable type is provided which is compact in construction and with high accuracy of measurement. The analyzer is comprised with a reaction container which is capable of having a plurality of cuvettes of disposable type set therein, an extracting and injecting unit for injecting a first reagent, a specimen and a second reagent into a disposable cuvette, a light measuring unit for emitting light to the cuvette, and for measuring absorbance thereof and a CPU for producing a calculated value based on outputs of the light measuring unit. The light measuring unit measures absorbance of the first reagent, specimen and second reagent injected into and reacted with each other in a disposable cuvette, and also measures an air blank value representing absorbance of an empty disposable cuvette and a first reagent blank value representing absorbance of a disposable cuvette having first reagent in the cuvette (S104, S106).
