摘要： There is provided a wind power generator capable of efficiently generating electric power by effectively utilizing the energy of wind even if the wind is weak and regardless of a wind direction, and easily increasing in size and in power with a simple structure. The wind power generator includes: a wind tunnel formed by a cylindrical member erected on a foundation in a vertical direction; a plurality of wind-collecting plates that extends from a circumferential wall of the cylindrical member in directions normal to the circumferential wall; a plurality of upper and lower guide plates provided between the wind-collecting plates; a plurality of wind inlets that introduces wind collected by the wind-collecting plates into the wind tunnel; back-flow preventing means that allow only the flow of wind blowing from the outside of the cylindrical member into the inside of the cylindrical member; a turbine that is driven by wind blowing out from one end of the wind tunnel, and power generator that is driven by the turbine.

摘要： [Object] To reduce pumping loss in a six-cycle internal combustion engine and increase the output.
[Solution Means] Exhaust is performed by opening an exhaust valve 30 when a piston 14 moves down after intake, compression, first-stage ignition, and combustion, and an intake valve 20 is also opened before the piston 14 reaches a bottom dead center, and scavenging and intake are performed until the piston 14 moves up again. Then, by closing both of the valves 20 and 30 and moving up the piston 14, compression is performed, and fuel is injected from a fuel nozzle 40. Then, when the piston 14 reaches a top dead center (or the vicinity of the top dead center), second-stage ignition is performed by an ignition plug 12. The piston 14 moves down in response to combustion, and the exhaust valve 30 is opened for exhaust. By combining an intake stroke → a compression stroke → a combustion stroke → an exhaust stroke in a four-cycle internal combustion engine with an intake and compression stroke → a combustion and exhaust stroke in a two-cycle internal combustion engine, pumping loss is reduced, the output is increased, and thermal efficiency is improved.

摘要： The present invention relates to a camshaft that opens and closes an exhaust valve in an exhaust port and an intake valve in an intake port of an internal combustion engine, in which the intake valve alternately opens and closes the intake port, and the exhaust valve alternately opens and closes the exhaust port, when a piston reciprocates in a cylinder. The camshaft comprises, as a cam that opens and closes the exhaust valve and the intake valve, a ball cam whose protrusion amount changes according to rotation of the camshaft, wherein the camshaft has a double structure consisting of an inner shaft and an outer shaft provided in a manner that the inner shaft is helically displaced with respect to the outer shaft around an axis of the camshaft according to a rotation speed of the camshaft, and the ball cam is accommodated movably in a guide groove provided in the inner shaft and protrudes from the outer shaft, and a protrusion amount of the ball cam from the outer shaft changes when the ball cam moves in the guide groove due to the helical displacement of the inner shaft with respect to the outer shaft, wherein, on a contact surface between the outer shaft and the inner shaft, a helical screw is provided, and at a bottom of the outer shaft and the inner shaft, a pressing spring is provided.
