摘要： An object is to facilitate checking of functional normality of a pilot check valve. A wind turbine generator includes a pilot check valve for restricting a flow of hydraulic oil relative to each oil hydraulic cylinder for changing a pitch angle of each blade, and the pilot check valve functions for fixing the pitch angle of the blade to a feather position in a state in which rotation of the blade is stopped. The function of the pilot check valve may be hindered. The wind turbine generator detects an operation state of the blade during a process of changing the pitch angle of the blade from the feather position to a fine position, and compares the detected operation state of the blade to an operation state of the blade when the pilot check valve functions normally, to determine whether or not there is any abnormality in the pilot check valve.

摘要： A composite growth-assisting substrate 10 is formed by epitaxially growing a separation-assisting compound semiconductor layer 10k composed of a non-GaAs III-V compound semiconductor single crystal, and then a sub-substrate 10e composed of a GaAs single crystal in this order, on a first main surface of a substrate bulk 10m composed of a GaAs single crystal. The sub-substrate portion 10e is then separated from the composite growth-assisting substrate 10, so as to be left as a residual substrate portion 1 on a second main surface of the main compound semiconductor layer 40, and a portion of the residual substrate portion 1 is cut off to thereby form a cut-off portion 1j having a bottom surface used as a light extraction surface. By this configuration, the light emitting device is provided as allowing effective use of the GaAs substrate, and increasing the light extraction efficiency.

摘要： An attachment lens is arranged in a stage subsequent to a scanning lens. After a laser beam is converged by the scanning lens, the laser beam is converted into a parallel beam by the attachment lens. When the scanning lens is displaced in a direction perpendicular to an optical axis of the laser beam, a traveling direction of the laser beam is bent by a predetermined angle immediately after the laser beam passes through the scanning lens. Then, the traveling direction of the laser beam is further bent by a predetermined angle in the same direction by the passage of the laser beam through the attachment lens. Accordingly, a final swing angle of the laser beam outgoing from an outgoing window is increased by a swing angle imparted by the attachment lens compared with the case where the attachment lens is not arranged. One of lens surfaces of the attachment lens is formed in a toroidal surface, which allows the laser beam to have a long outline in a vertical direction.

摘要： A scan trajectory of a laser beam is controlled based on external signals each related to a driving direction and a driving speed, a result obtained by detection of an obstacle, and signals related to distances to the obstacle. For example, at the time of a right turn, a scan trajectory for increasing scan frequency on a portion shifted in a right-turn direction from a center axis in a driving direction is set. At the time of high-speed driving, a scan trajectory for increasing scan frequency on a center portion in the driving direction is set. When the obstacle is detected at a position corresponding to a distance shorter than a threshold distance, a scan trajectory for increasing scan frequency in the vicinity of the obstacle is set. Detection and monitoring are performed at the time of: changing of the driving direction, the high-speed driving, and the detection of the obstacle.

摘要： In a beam irradiation device of the present invention, laser beams emitted from a semiconductor laser impinge on an irradiation lens supported by a lens actuator. The laser beams that have passed through the irradiation lens change in outgoing angle in the direction of a y-z plane as the lens actuator is driven. A laser beam scan in the target region is thus performed. A part of the laser beams that have passed through the irradiation lens is reflected and separated by a beam splitter. The separated beams are converged on a PSD through a converging lens. A DSP control circuit monitors a scan position of the laser beams that have passed through the irradiation lens based on a signal from the PSD. When an irradiation position has deviated from a scan trajectory, the DSP control circuit controls an actuator driving circuit to draw the irradiation position back onto the scan trajectory. This beam irradiation device can realize a smooth and stable beam scan operation with a simple construction.

For example, at the time of a right turn, an irradiation pattern for increasing irradiation frequency on a portion shifted in a right-turn direction from a center axis in a driving direction is set. At the time of high-speed driving, an irradiation pattern for increasing irradiation frequency on a center portion of a forward region in the driving direction is set. When the obstacle is detected and a distance to the obstacle is shorter than a threshold distance, an irradiation pattern for increasing irradiation frequency in the vicinity of the obstacle is set. Detection of the obstacle and monitoring of a state thereof are adequately and smoothly performed at the time of changing of the driving direction, the time of high-speed driving, and the time of detection of the obstacle.
