    Abstract: PROBLEM TO BE SOLVED: To provide an air seal for a gas turbine engine which improves a durability especially at high temperatures. SOLUTION: An air seal (7) includes a seal substrate and an abradable seal layer on the seal substrate. The abradable seal layer is formed by a high density polyimid foaming material, or preferably a thermomechanically high density foaming material. The air seal (7) is bonded to a stationary engine member such as a stator box (6) or a case (3). COPYRIGHT: (C)2003,JPO

    IPC: G01N21/91

    Abstract: PROBLEM TO BE SOLVED: To provide an improved method and system for inspecting a defect in parts. SOLUTION: This system has and is constituted of the following steps; a step for putting the parts for inspection in an immersion tank, a step for pouring a liquid mixture of a dye-permeating liquid and an ultracritical carbon-dioxide solvent into the immersion tank, a step for providing ample time enough for keeping the parts to remain immersed in the liquid mixture until the dye-liquid has fully permeated the possible defect inside the parts, a step for taking the immersed parts out of the immersion tank, and a step for doing a test for the immersed parts in order to check whether they have a defect or not.

    IPC: G01N21/91

    Abstract: A process for inspecting a part (42) to detect defects in the part comprises the steps of placing a part (42) to be inspected in an immersion tank (40), introducing a mixture of a penetrant dye and a supercritical carbon dioxide solvent into the immersion tank (40), maintaining the part immersed in the mixture for a time sufficient for the penetrant dye to penetrate any defects in the part, removing the part (42) from the immersion tank (40), and inspecting the part for the presence of any defects.
