A particles capturing system includes a venturi filter device, a cyclone filter device, a plurality of first nozzles and air to flow through the system. The venturi filter device has an air intake portion, a neck portion and an air outlet portion. The cyclone filter device, disposed in the air outlet portion, has an entrance and an exit. The plurality of first nozzles, disposed inside the venturi filter device, have a height greater than that of the the neck portion. When the air flows, the air enters the venturi filter device via an air inlet of the air intake portion, then orderly passes through the neck portion and the plurality of first nozzles, then enters the cyclone filter device via the entrance, and finally leaves the cyclone filter device via the exit, such that particles in the flowing air can be captured.

Particles capturing system

The present disclosure relates to a heat dispersion apparatus for motors, which comprises: a cooling fan, and a guide cover. The cooling fan has a plurality of fan blades disposed radially on a back plate, the outside portion of the fan blades axially extend beyond the periphery of the back plate, and the back plate is a cone structure. The guide cover has air inlet, a plurality of holes opened on the surface of the air inlet with slots, the slots arranged in accordance with the rotation direction of the cooling fan, and each slot set up a chamfer for leading into more air to reduce temperature. With this device, airflow supercharging and peripheral axial flow are improved, and the slot structure and the cooling fan blades can introduce a large scale of air; thereby the present invention provides a significant improvement to motors.

Heat dissipation apparatus for motors

A measuring system, during a measurement process thereof, uses a phase-locked loop mechanism of a stator phase voltage and a stator phase current of a three-phase AC motor to effectively remove harmonics and to sense and obtain the amplitude effective values of the phase voltage and the phase current of the three-phase AC motor and the phase difference between the phase voltage and phase current. Therefore, the measuring apparatus is capable of quickly and accurately calculating the input power of the motor without having to measure the parameters of the motor.

Measuring apparatus including phase locked loop and measuring method thereof

A wideband antenna includes a grounding terminal, a first radiator disposed on a first plane, a feeding terminal formed on the first radiator, where the feeding terminal is to transmit and receive radio signals via the first radiator, and a second radiator disposed on the first plane, electrically connected to the grounding terminal, and including a part parallel to a side of the first radiator, wherein a minimum gap between the second radiator and the first radiator allows the second radiator and the first radiator to generate a coupling effect therebetween, so as to exchange radio signals between the second radiator and the first radiator.

Wideband antenna

A seawater desalination unit is disclosed, which comprises: a frame, an exit filtration part, and a water drawing part. The frame is configured with a reservoir, a water intake pipe and a water discharge pipe in a manner that the water intake pipe is connected to the reservoir respectively via one end thereof, while allowing a first check valve to be disposed at a position between the reservoir and the water intake pipe, and the water discharge pipe is connected to the second filtration part and the reservoir respectively via two opposite ends thereof, while allowing a second check valve to be disposed at a position between the high-pressure reservoir and the water discharge pipe. Moreover, the water drawing part is arranged in fluid communication with the water intake pipe.
