摘要： A wind energy generation system includes a tower, a nacelle provided in an upper portion of the tower to be rotatable around a central axis of the tower, a hub provided in front of the nacelle to be rotatable around an axis orthogonal to the central axis, and one or more blades provided in the hub. The hub includes a hub body portion to which the blades are attached, and a fitting protruding portion that protrudes from a back surface side of the hub body portion. A fitting portion having an opening portion is provided in front of the nacelle, and the fitting protruding portion is fitted into the fitting portion from the opening portion. In the wind energy generation system, outflow of oil to the outside of the generation system can be inhibited.

摘要： The present invention provides a singularity locator that enables a singularity such as a fault to be located even in a near-end section. One embodiment of the present invention is a singularity locator (1) that locates a singularity by comparing a transmission wave with a reflected wave of the transmission wave reflected at the singularity at which impedance changes. The transmission wave is a frequency modulated continuous-wave (FMCW) with a continuously modulated frequency, and the singularity is located based on a difference in frequency between the transmission wave and the reflected wave.

摘要： Photosynthetic algae capable of photosynthesis by absorbing light and incorporating carbon dioxide are cultured in an algae culturing apparatus. The algae culturing apparatus can be part of an algae culturing system. The algae culturing apparatus has a culture tank configured to accommodate algae and a culture solution for culturing the algae. A flow generator is installed on the culture tank and is configured to generate a flow of the culture solution from a center of the culture tank toward an inside wall part of the culture tank on a liquid surface of the culture solution and in a region of the culture solution close to the liquid surface by moving the culture solution on the liquid surface and in the region close to the liquid surface in the culture tank from the center of the culture tank toward the inside wall part of the culture tank.

摘要： A thermal power plant has an exhaust gas system, a feed-water system, a high-pressure feed-water heater provided to the feed-water system, a main economizer, a catalytic NOx removal equipment, and a sub economizer. The main economizer is provided to the secondary side of the high-pressure feed-water heater of the feed-water system and increases the temperature of the feed-water by using the residual heat of the combustion gas from the boiler. The catalytic NOx removal equipment is provided to the secondary side of the main economizer of the exhaust gas system. The exhaust gas is supplied to the catalytic NOx removal equipment at a required temperature or higher. The sub economizer is provided between the high-pressure feed-water heater and the main economizer and increases the temperature of water by using the exhaust gas on the secondary side of the NOx removal equipment.
