Abstract: Provided is a concentrated solar power gas turbine that enables efficient operation to allow a reduction in capacity of the start-up driving source used for compensating for the shortage of solar heat quantity at the start-up/acceleration. The concentrated solar power gas turbine (GT1) includes a compressor (1) for taking in air and increasing the pressure thereof, the compressor (1) being provided with a start-up driving source for start-up/acceleration; a solar central receiver (2) for heating the high-pressure air, the pressure of which has been increased by the compressor (1), by the heat of sunlight collected by a heliostat to increase the temperature thereof; and a turbine (3) for converting thermal energy possessed by the high-temperature/high-pressure air to mechanical energy, wherein the fluid flow in the solar central receiver (2) is shut off to store heat in the period from the shutdown of the turbine (3) to the start-up thereof.

Abstract: Heat transfer pipes uniformly heat a compressible working fluid passing there through with a simplified supporting structure and reduced manufacturing costs. A solar central receiver (3) on top of a tower on the ground includes heat transfer pipes (16) arranged in the south-north direction; and a casing (14) accommodating the pipes (16) and has a solar radiation inlet (15) through which sunlight reflected by heliostats on the ground is transmitted to the lower surface side of the pipes (16). The pipes (16) are at equal intervals on a solar radiation receiving surface (11) parallel to a heliostat field on which the collectors are, or inclined with respect to the heliostat field on which the collectors are, and the diameters of the pipes (16) are substantially inversely proportional to the shortest distance from the inlet (15) to the central axes of the respective pipes (16) in the longitudinal direction.

Abstract: An outboard motor S has an exhaust manifold passage 37 for carrying exhaust gas from combustion chambers 30. The exhaust manifold passage 37 is formed in a part of a cylinder head 22 in an exhaust-side part of an internal combustion engine E on the side of the cylinder head 22 with respect to a joint surface P of a cylinder block 20 joined to the cylinder head 22. An exhaust passage 38 is formed in the cylinder block 20 and connected to the exhaust gas outlet 37e of the exhaust manifold passage 37 in the joint surface P. An electrical equipment box 50 holding electrical equipment is placed in the exhaust-side part so as to overlap the exhaust passage 38 when viewed in vertical direction. An electrical equipment box 50 is disposed adjacent to the cylinder head 22 with respect to the direction parallel to the axes of cylinders 20a.

Abstract: In an outboard motor control system, equipped with two outboard motors and actuators for steering, changing shift position and regulating engine speed, two navigation units responsive to operations of the operator for producing outputs indicative of actuator operation commands, two ECUs that control the operation of the actuators based on the outputs from the navigation units, an output forwarding ECU which forwards the outputs of one of the navigation units to the ECUs, and two switchover buttons for changing the outputs to be forwarded. Therefore, only the set of outputs for the one navigation unit selected by the operator is sent to the ECUs. In other words, in the case where multiple navigation units are provided, use of the navigation units is limited to a desired one thereof, so that the outboard motors can be stably controlled even when the control inputs to the individual navigation units are different.
