Abstract: A control apparatus C of a horizontal axis wind turbine apparatus WTG calculates the value en of a pitch angle command for each blade based on the rate of change ?D of the azimuth angle ? of a Nacelle N and the rotor azimuth angle of the blades B1, B2 and B3, causes the rotor R to generated torque around the yaw axis by periodically controlling the angle change of the pitch angle of the blades B1, B2 and B3, and using that torque, controls the rate of change of the azimuth angle of the nacelle N. The value of that angle change is calculated as a value that increases as the inputted value of the rate of the change ?D increases.

Abstract: To provide a horizontal axis wind turbine capable of reducing flutter, and by extension, reducing the load on the wind turbine, without controlling the yaw, regardless of the direction of the wind relative to the nacelle. When the wind speed is above a specific value, the yaw angle of the nacelle is held constant, the blade pitch angle is controlled according to the yaw angle Y of the wind direction relative to the nacelle, and the rotor is allowed to rotate freely. Even when the yaw angle of the nacelle is held constant, allowing the rotor to rotate freely makes it possible to reduce the load by avoiding flutter.

Abstract: Even when a remaining amount of an image memory built in a digital camera is decreased, the photographing can be further continued while reserving a photographed image. An image which is obtained from an image input unit including image pickup means is accumulated into an image memory. When a remaining amount calculating unit detects that the remaining amount of the imag memory is small, an image record discriminating unit compares it with an image size in a photograph mode at that time which is obtained from an image size table, thereby discriminating whether the continuation of the photographing can be performed or not. When the photographing is impossible, an image selecting unit selects an old image, an image in which the number of colors is small, or the like on the basis of management data regarding the photographed images in a memory managing table. The selected image is transmitted by a PHS communication by a data transmitting apparatus.

Abstract: The purpose of the invention is to protect, in a horizontal axis wind turbine with an exhaust aperture for exhausting air from within the nacelle, the exhaust aperture and the internal structures from storm winds through facing the exhaust aperture away from the storm wind, even when storm winds are received from all directions relative to the nacelle. A rotary duct is attached to the nacelle so as to be able to rotate freely in the yaw direction, and is rotated in the yaw direction in accordance with changes in the wind direction. The exhaust aperture is provided at a position that changes direction depending on the rotation of the rotary duct in the yaw direction. By rotating the rotary duct in the yaw direction so that the exhaust aperture will face the downwind side in accordance with changes in the wind direction, the exhaust aperture can be faced away from storm winds, even when storm winds are received from all directions in relation to the nacelle.
