Abstract: A fire nozzle quick-assembly light is provided, which comprises a frame, a luminous device and an electricity generation device. The luminous device and the electricity generation device are sited to the frame. The luminous device is for illuminating in the fire scene, and the electricity generation device is for providing electricity to the luminous device. The fire nozzle quick-assembly light could depend on fireman's needed to be assembled or removed from the fire equipment quickly and provide high illumination to help extinguish fire, evacuate and lower the possibility that fireman suffers injury in dark environment. When the fire accident happens in the place with sufficient light, fireman does not need the additional illumination at this time. The fire nozzle quick-assembly light could be removed from the fire equipment easily to lower the weight.

Abstract: The present invention provides a swirly fluid sprinkler comprising a sprinkling body, a fluid guide, and an electrical generator. The fluid guide disposed inside the fluid inlet of the sprinkling body includes a plurality of swirl channels for dividing a fluid flow into a plurality of swirly fluid flows. The electrical generator disposed inside the sprinkling body and opposite to the fluid guide has a plurality of blades disposed on the top thereof. Each of the blades has an inclining angle wherein the blade surface opposite to the fluid guide has an angle in relation to the corresponding swirly fluid for receiving the propelling force from the swirly fluid so as to rotate the electrical generator and thereby generate electrical power. In another embodiment, the swirly fluid sprinkler further has a lighting module for providing illumination while the water spray is discharged.

Abstract: A wind-tunnel type power generator includes an outer cover, a turbine rotor, an air escape valve, and at least a rear fin. The outer cover is a convergent-divergent shape and the turbine rotor is installed into an inner flowing path thereof, the air escape valve is installed on the outer cover and the rear fin is installed on the surface of the outer cover. The acceleration of the outer cover, the higher efficiency of the turbine rotor, and the reducing pressure of the air escape valve is to gain the wider operation area, smaller space, lower weight, lower noise, and higher efficiency of the wind-tunnel type power generator.

Abstract: An axial flow type cooling fan, comprising an upper casing, a lower casing, a rotor assembly, and a driving unit. The lower casing and the upper casing enclose an inner space. The rotor assembly is housed in the inner space and performs a rotational movement. The rotor assembly further comprises a plurality of blades, attached to a central shaft and having a peripheral ring, from which a peripheral rim extends outward. The driving unit has electric coils on the upper or lower casings and permanent magnets on the peripheral rim, causing the rotational movement of said rotor assembly. By the arrangement of these structural parts, an increased area of air flow and consequently increased air flow are attained, while drag and noise are reduced.

Abstract: A dental hand piece, comprising a casing, an axis, front and rear bearings, a turbine, a front lid, and a drill head. Air of high pressure enters the casing through an air inlet, is led through a front ring channel, hits the air turbine in an axial direction, driving a rotational movement of the air turbine, passes through a rear ring channel and leaves the casing through an air outlet. A path for fluids from the drill head to reach the air outlet is blocked, effectivity of driving is increased, and noise is reduced.

Abstract: A structure of a 50 pound thrust level gas turbine jet engine combustor is a small type 50 pound gas turbine jet engine combustor. The combustor includes a combustor outer liner, a combustor inner liner and a hub. Pressure swirl fuel atomizer and thin film cooling devices are further used. In the combustor, a primary jet flow is matched with a jet tube so as to build a stable recirculation in the primary zone. 12 SIMPLEX fuel atomizers are installed in the inner liner for jetting fuel radially. The fuel must be jetted properly, if it is too close the front plate, the droplet will impact the front plate, then the downstream will possible destroy the recirculation structure. Therefore, if the fuel is jetted in proper positions, then the retaining time of fuel will be reduced greatly and the burning in the primary zone can be enhances. By analyzing and testing, it is appreciated that high temperature will induce at the middle section near the wall of the inner liner.

The front plunger pressure-swirl atomizer is installed at the seat of an engine. The present invention has the advantages of occupying a smaller space, only needing a small operating pressure, a simple flow channel structure, and fewer components, being easily assembled and a superior atomizing property. Therefore, the defects, such as complex finishing process of flow channel and difficult to be assembled, in the prior art are improved effectively.

High combustion efficiency and satisfactory outlet temperature pattern factor can be obtained in the present combustion system of the engine. This is because the system possesses the characteristics such as fine spray of liquid fuel, long residence time of fuel droplets, efficient flame holding mechanism and good mixing in the dilution region. As a result, safety and maneuverability of the present engine can be enhanced in comparison with the engines of prior art.
