A shroud segment is incorporated in a gas turbine engine so as to suppress influence of hot combustion gas on a turbine case which has a groove and a hook for engagement with the shroud segment. The shroud segment is provided with a back plate formed in an arc shape, a front end of the back plate being supported by the groove so as to allow displacement in an axial direction of the gas turbine engine, a slot circumferentially formed on an outer surface of the back plate, the slot being engaged with the hook so as to be immovable in the axial direction and a touching member integrally formed on an inner surface of the back plate for touching with a rotating turbine blade. The slot is configured so as to satisfy an inequality of v

In order to quantitatively evaluate actual circulation quantity of bed material extremely simply and to enhance accuracy of comparison of results of thermal balance examined through simulation or the like with actual operation results, time is measured which is required for bed material in a downcomer 5 to reach an upper predetermined height H1 from a lower reference height H0 during stopped feeding of fluidizing air to an external heat exchanger 7; a flow rate of the bed material as circulation quantity is determined from the time and an accumulated amount of the bed material based on an inner diameter D of the downcomer 5.

A ceramic composite material is comprised of a fabric of fibers of an inorganic substance; and a matrix for combining the fibers. The matrix consists essentially of a ceramic. The matrix is formed by burying the fabric in a mixture of a powder of carbon, a powder of silicon and a medium including an organic solvent, producing an oscillation in the mixture to impregnate the fabric with the mixture, and calcining the fabric impregnated with the mixture.

A method for determining a shape of a shift roll for a rolling mill, includes the steps of determining a necessary control amount distribution αi for a plate crown with respect to plate widths, based on a distribution of the number of plates rolled by a target rolling mill with respect to plate widths, and providing a maximum radius difference yA0 of the shift roll. The method further includes the steps of preliminarily determining a line yi of a roll radius distribution with respect to plate widths, based on the necessary control amount distribution αi and the maximum radius difference yA0, shifting the line yi of the roll radius distribution by a maximum roll shift to obtain a distribution ΔyBi of a roll gap change amount with respect to plate widths under the maximum roll shift, and smoothing sharp local changing part of the distribution ΔyBi of the roll gap change amount.

The invention provides a dovetail structure of a fan which attaches a fan 20 having an inlet hub diameter smaller than an outlet hub diameter to a portion around a discoid disc rotationally driven by a turbine. The disc 10 has a plurality of dovetail grooves 12 extending at a fixed angle θ1 with respect to an axis 1 of a rotation axis from a leading edge 10a to a trailing edge 10b thereof, and spaced at a fixed angle in a peripheral direction. The fan 20 has a dovetail portion 22 extending at the same angle as an angle of the dovetail groove and capable of being fitted to the dovetail groove, in an inner end thereof.

A first centrifugal impeller and a second centrifugal impeller are arranged in such an orientation that back sides of the first centrifugal impeller and the second centrifugal impeller face to each other. Bearings are cylindrical roller bearings and a thrust bearing. The cylindrical roller bearings are arranged at two axially spaced supporting positions respectively, and support a radial load applied to the rotating shaft. The thrust bearing supports a thrust load applied to the rotating shaft.

The object of the present invention is to provide an inspection apparatus for liquid crystal drive substrates that improves the inspection accuracy of liquid crystal drive substrates, judges defect type more accurately, and does not cause a decrease in throughput. In order to achieve this object, the present invention provides an inspection apparatus for liquid crystal drive substrates that discriminates defective pixels having an abnormal voltage and normal pixels having a normal voltage based on pixel voltage by arranging an electro-optical element plate in opposition to a liquid crystal drive substrate on which pixel electrodes are arranged in the form of a matrix, and calculating the actual voltage of each pixel electrode in the form of a pixel voltage based on the voltage image of the electro-optical element plate obtained by writing a prescribed voltage to the pixel electrodes, and on the electro-optical characteristics of the above electro-optical element plate, wherein the inspection apparatus comprises an image processing apparatus that an image processing apparatus that classifies pixel electrodes of defect candidates for each defect type by comparing said pixel voltage with a threshold value set for each defect type of pixel defect, and finally judges said pixel electrodes of defect candidates for each defect type as defective pixels of each defect type based on judgment conditions provided for each defect type.
