| 20100014983 | TURBINE BLADE - The present invention provides a turbine blade that is exposed to a high temperature atmosphere at relatively high temperatures and to a low temperature atmosphere at relatively low temperatures, including: a concave-curve-like pressure surface that is concaved along a flow direction of fluid; a convex-curve-like suction surface that is convexed along the flow direction of the fluid; and a concave and convex formation device which causes a concave and convex portion along the flow of the fluid to appear on the suction surface when the turbine blade is exposed to the low temperature atmosphere, and which turns the suction surface into a smooth surface along a convex curve surface of the suction surface when the turbine blade is exposed to the high temperature atmosphere. With this construction, it is possible to reduce a pressure loss of the turbine blade at high Reynolds numbers in the low temperature atmosphere without increasing a pressure loss of the turbine blade at low Reynolds numbers in the high temperature atmosphere. | 01-21-2010 |

| 20090131467 | Heterocycle Compound, and Production Process and Application Thereof - The compound of the present invention is a novel compound which has a specific heterocycle skeleton, particularly a pyrazolonaphthyridine or pyrazoloquinoline skeleton having an organic group (e.g., a carbocycle and a heterocycle) bonding through an alkylene group at 3-position and a carbocycle bonding at 5-position and has a phosphodiesterase IV inhibitory activity. At least one of the ring (the carbocycle or the heterocycle) bonding at 3-position of the pyrazolonaphthyridine skeleton and the carbocycle bonding at 5-position may have a halogenated alkyl group and/or a halogenated alkoxy group as a substituent. Such a compound or a salt thereof is useful as a phosphodiesterase IV inhibitor and the like. According to the present invention, a novel compound having a high phosphodiesterase IV inhibitory effect can be provided. | 05-21-2009 |
