    摘要: An impingement cooled structure includes a plurality of shroud members disposed in a circumferential direction to constitute a ring-shaped shroud surrounding a hot gas stream, and a shroud cover mounted on radial outside faces of the shroud members to form a cavity therebetween. The shroud cover has a first impingement cooling hole which communicates with the cavity and allows cooling air to be jetted to an inside thereof so as to cool an inner surface of the cavity by impingement. The shroud members each has a hole fin. The hole fin divides the cavity into a plurality of sub-cavities. Further, the hole fin has a second impingement cooling hole which allows the cooling air having flowed through the first impingement cooling hole to be jetted obliquely toward a bottom surface of the sub-cavity adjacent thereto.

The turbine airfoil further includes a hollow cylindrical insert (20) which is positioned inside the internal surface of the turbine airfoil and to which the cooling air is supplied. The insert has a plurality of impingement holes (21) for impingement-cooling the internal surface (12).

    摘要: The present invention solves the issue of bacterial infection by medical devices such as intracorporeal indwelling catheters. The present invention relates to an ultrasonic medical apparatus including a medical device (titanium oxide coated medical device 10) covered with a titanium oxide material (titanium oxide alone or a titanium oxide composite material) and ultrasonic irradiation means 20. Ultrasonic irradiation of the titanium oxide material, which exists on a surface of the medical device, causes the surface of the medical device to exert beneficial effects such as antibiotic action, the stimulation of angiogenesis, and the degradation of a blood clot and a biofilm.

    摘要: A boundary acoustic wave device that has a three-medium structure and that prevents a high-order mode spurious response includes a piezoelectric substrate, a first dielectric layer laminated on the piezoelectric substrate, a second dielectric layer laminated on the first dielectric layer, and an IDT electrode provided at an interface between the piezoelectric substrate and the first dielectric layer. The boundary acoustic wave device utilizes a Stoneley wave that propagates along the interface. Where V1 denotes an acoustic velocity of a slow transversal bulk wave in the piezoelectric substrate and Va denotes an acoustic velocity at an anti-resonant point in a high-order mode of the Stoneley wave, Va>V1 is satisfied.
