摘要： A heat dissipation fan has a casing, two fans and multiple stationary blades. The fans are co-axially rotatably mounted in the casing. Multiple rotating blades are arranged around the outer periphery of each fan. The stationary blades are secured in the casing and between the rotating blades of the two fans. The angle of the rotating blades on both of the fans is the same. The angle of the stationary blades is perpendicular to that of the passing rotating blades. Accordingly, the airflow generated by the dissipation fan will be enhanced with the multiple layers of rotating blades. The stationary blades reverse the direction of the airflow. The dissipating effect of the dissipation fan is further increased.

摘要： This invention relates to a positive displacement pump which allows a liquid additive (such as liquid fertilizer) to be introduced into another liquid stream (such as water) and to be mixed in a constant proportion. One end of the pump can be connected to a faucet and the other end to a typical garden hose or other device. Water enters the pump through a faucet and is redirected (bent) by an upper stator which allows the water to rotate turbine vanes. The turbine is rotatably connected to a cam and the rotation of the cam moves pistons which allows liquid fertilizer to be drawn in from its reservoir. The liquid fertilizer flows through a tube and into one of two pistons. Then, the liquid fertilizer is dispelled through one of the exit tubes through the pumping action of the pistons. The water which was used to turn the turbine then combines with the liquid fertilizer as it comes out of the exit tubes and a water/fertilizer mixture is created.

摘要： A partition partitions off a motor chamber and a pump chamber, through which a cooling water flows, a substantially cylindrical-cup shaped rotor is arranged in the pump chamber, a circuit board is disposed in the motor chamber to be in parallel to an annular-shaped end surface of the rotor, a magnetism detecting element is mounted on that portion of the circuit board, which faces a magnet portion of the rotor, and exothermic electronic parts are mounted on the remaining portion of the circuit board. The magnetism detecting element and the exothermic electronic parts, respectively, are arranged in opposite positions in a substantially annular-shaped area of the circuit board, which faces the annular-shaped end surface of the rotor, and a thickness of an annular-shaped wall portion of the partition facing the annular-shaped end surface of the rotor is made thin in a portion adjacent to the exothermic electronic parts on condition that an annular-shaped surface of the annular-shaped wall portion on a side of the annular-shaped end surface of the rotor is a non-inclined flat surface.

摘要： A one-stage transmissible turbocharger includes a turbine wheel contained in a front current-guider and a rear current-guider, increasing air pressure to elevate horsepower and speeding up burning of gas coming out of a carburetor to save fuel consumption. The turbine wheel has a plurality of leaves respectively helically formed to have 32 angles to make a catch inlet section to elevate air volume to be caught in, and a final axial pressure section for producing centrifugal current so as to give the turbine wheel functions of both axial current and centrifugal current. In addition, the turbocharger has buffer springs for protecting a belt wheel and its bolts from damaged or broken.

摘要： Cooling fan with a fan wheel equipped with blades and an electric motor that has a stator and a rotor that is supported in a rotationally fixed manner on a driven shaft. For a purpose of a cost-saving and compact design of the cooling fan with low fan noise, the rotor is embodied as an external rotor with a bell-shaped pole housing encompassing the stator. The fan wheel is rotationally fixed in relation to the pole housing so that the fan wheel axially encompasses the pole housing at least partially and contacts the outer circumference of the pole housing at a number of points.

摘要： A dual function air pump has a compressor with an inlet connected to a first port and with a first outlet connected to a second port. The air to the compressor is directed by a first tube from the first port, such that a suction effect exists at the first port. The air pumped out of the compressor is directed to the second port by a second tube, such that an exhaust or blowing effect exists at the second port. A pressure gauge is connected by an auxiliary tube to the second tube. The compressor further has a second outlet connected to a control switch assembly by a third tube.

摘要： An irrigation pump for use in irrigating small fields or supplementing larger irrigation systems can also be used for portable water supply for emergency, military, or for underdeveloped countries. The pump system is designed to be light-weight and semi-portable and can be powered with a small engine or electric motor. The apparatus uses a down well impeller that is driven by a flexible vertical shaft and a vertical shaft motor drive or engine. The pump impeller incorporates its own thrust and journal bearings for the pump shaft. The bearings are water lubricated. The main drive shaft is flexible and elongated and is supported over its entire length with a flexible shaft guide sleeve. The flexible drive shaft is surrounded by a convoluted well pipe so that the drive shaft and the well pipe can be removed from the well casing bore as a unit and then coiled for storage. A flange on the outlet fitting can be used to bolt the entire assembly of engine and outlet fitting to the well head at a well casing flange. That entire assembly of outlet fitting, engine (or motor), well pipe, drive shaft and impeller can be removed as a unit from the well casing by simply unbolting the outlet fitting from the casing.
