    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.

    摘要: A delayed interferometer includes a branching unit that branches an optical signal into a first optical signal and a second optical signal; a guiding unit that guides the first optical signal in a first optical path to delay the first optical signal when a polarization direction of the first optical signal is the first direction, and guides the first optical signal in a second optical path when the polarization direction of the first optical signal is the second direction perpendicular to the first direction; a demodulating unit that causes the first optical signal guided in the first optical path or the second optical path and the second optical signal branched by the branching unit to interfere with each other, thereby demodulating the optical signal; and a polarization direction adjusting unit to adjust the polarization direction of the first optical signal in the first direction or the second direction.

    摘要: Provided are a stress analysis method and stress analysis equipment that enable a detailed stress measurement, by using both a photoelasticity measurement method and a stress measurement (mechanoluminescence measurement) which utilizes a mechanoluminescent substance to measure a stress state of an object. Physical quantities that are measurable include individual principal stress component and a principal stress direction. The photoelasticity measurement method alone cannot measure individual principal stress component values.

    摘要: Light incident on an input optical fiber is separated into p-polarized light and s-polarized light by a birefringent crystal. A voltage to be applied to a liquid crystal element having electrodes associated with the ray axes of the polarized light waves is controlled in order to convert the p-polarized light into s-polarized so that both the polarized light waves will be s-polarized light. Otherwise, the s-polarized light is converted into p-polarized light so that both the polarized light waves will be p-polarized light. A polarized-wave separation film located behind the liquid crystal element transmits p-polarized light and reflects s-polarized light. When both the polarized light waves propagated through the liquid crystal element are s-polarized light, the light reflected from the polarized-wave separation film is reflected from a total-reflection film, and reflected again from the polarized-wave separation film. The resultant light falls on the birefringent crystal again via the liquid crystal element, and is restored to non-polarized light by the birefringent crystal. The non-polarized light then falls on a first output optical fiber. In contrast, when both the polarized light waves propagated through the liquid crystal element are p-polarized light, the p-polarized light is transmitted by the polarized-wave separation film, and then restored to non-polarized light after falling on the birefringent crystal via another liquid crystal element. The resultant light then falls on a second output optical fiber.

    摘要: Gas introduction piping introduces process gas for plasma generation into a processing chamber. A pressure regulating valve is provided at an exhaust pipe. A mass flow controller is provided at the gas introduction piping and regulates the flow rate of the process gas. A pressure gauge detects the pressure of the processing chamber. A control unit controls pressure within the processing chamber by controlling an extent of opening of the pressure regulating valve based on values detected by the pressure gauge. The control unit receives flow rate data indicating the rate of flow of process gas from the mass flow controller and determines the presence or absence of faults at the mass flow controller based on an extent of fluctuation of the values detected by the pressure gauge when a high-frequency is inputted to the electrode.
