The Chugoku Electric Power Company, Incorporated is an electric utility with its exclusive operational area of Chūgoku region of Japan. It is the sixth largest by electricity sales among Japan’s ten regional power utilities. It operates the Shimane Nuclear Power Plant.In 1982, Chugoku Electric Power Company proposed building a nuclear power plant near the island of Iwaishima, but many residents opposed the idea, and the island’s fishing cooperative voted overwhelmingly against the plans. In January 1983, almost 400 islanders staged a protest march, which was the first of more than 1,000 protests the islanders carried out. Since the Fukushima nuclear disaster in March 2011 there has been wider opposition to construction plans for the plant. Wikipedia.

A heat exchanger includes: a flow passage unit arranged with a plurality of planar flow passage bodies each arranged with two flow passages adjacent to each other in a same plane, the plurality of the planar flow passage bodies being layered in an intersecting direction that intersects with the plane, and in two of the planar flow passage bodies adjacent in the intersecting direction of the plurality of the layered planar flow passage bodies, each one of two flow passage ports in both ends of each of the flow passages of one of the planar flow passage bodies is connected to each one of two flow passage ports in both ends of each of the flow passages of another of the planar flow passage bodies; and a high-pressure pipe that covers an outside of the flow passage unit.


The observation image capturing part provided to the tip end of the cable of the internal observation device is made to smoothly approach the portion to be observed. For inserting into a pipe bore 41 a cable 2 of an internal observation device 1, the cable 2 is pushed into the pipe bore 41 to force an observation image capturing part 21 provided proximate a tip end of the cable to approach a portion to be observed 70 when performing internal observation of the pipe bore 41 of a pipelike structure 40 with the internal observation device 1. A guide tube 10 having an outside diameter substantially equal to an internal diameter of the pipe bore 41 to a degree that the guide tube 10 can be inserted in the pipe bore 41, and having an internal diameter substantially equal to an outside diameter of the cable 2 to a degree that the cable 2 can be inserted therein, is inserted into the pipe bore 41 that reaches the portion to be observed 70 and the cable 2 is inserted into a tube interior of the guide tube 10 from an outside of the pipe bore. There may be provided a curved part 12 proximate a tip end of the guide tube 10, the curved part 12 being configured to deflect a direction in which the tip end of the cable 2 that is inserted in a tube interior of the guide tube 10 is directed.

PROBLEM: To reduce power loss of a windmill blade and aerodynamic noise caused by the windmill blade, by weakening blade end vortexes generated at a blade end part of the windmill blade, and causing the blade end vortexes to be generated at positions apart from a blade end of the windmill blade. SOLUTION: A windmill blade 11 to be employed in a horizontal axis lift-type windmill includes: a blade body 12 having a streamlined cross-sectional shape in which a blade chord length gradually decreases from a blade root 15 toward a blade end 16; and a winglet 25, having a shape including a pointed tip 28, which is integrally provided to the blade end 16 of the blade body 12, the winglet 25 being configured in a shape such that the tip 28 is positioned further rearward in a rotation direction than a trailing edge 19 of the blade end 16 of the blade body 12 and further outward in a blade length direction than the blade body 12. A pressure difference can be reduced between upper and lower surfaces at a blade end part of the windmill blade 11, thereby being able to weaken blade end vortexes generated at the blade end part of the windmill blade 11, and cause the blade end vortexes to be generated at positions apart from the blade end, which enables a reduction in power loss and aerodynamic noise.
