摘要:
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.

A solar-thermal gas turbine generator is equipped with a compressor, a heat receiver, and a turbine. Additionally, there is a generator that is driven by the solar-thermal gas turbine to generate power; and a steam power generation cycle in which high-temperature air exhausted from the turbine is introduced into a steam generator and in which a steam turbine that is operated with steam generated at the steam generator drives a generator to generator power, wherein a solar-thermal steam generator that generates steam by being heated with heat collected by the light collector is provided upstream of the steam turbine of the steam power generation cycle, and a distribution ratio for distributing the sunlight collected by the light collector to the heat receiver and the solar-thermal steam generator is adjusted in accordance with the sunlight intensity.

Provided is a gas turbine combustor capable of reducing the size of a low-temperature air layer of pilot air formed between a pilot flame and a premixed flame and of improving the flame stability of the premixed flame. A gas turbine combustor, which is provided with a pilot burner that is provided at the center portion of a combustor main body formed in a cylindrical shape to form a pilot flame, and a plurality of main burners arranged so as to surround the outer periphery of the pilot burner to form a premixed flame, includes, as the ignition improving part, a channel blocking member that reduces the size of the low-temperature air layer of the pilot air formed between the pilot flame and the premixed flame.

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.

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. It is thus possible to increase freedom of arranging parts at positions farther from the cylinder head than the electrical equipment box and freedom of determining the sizes of those parts.
