A vibration assistant polishing module which comprises a polishing disk, a workpiece carrier tray, a linear guide way mechanism, a linkage, a motor and an adjustable eccentricity mechanism. The linear guide way mechanism includes a slide, a guide seat and a guide rod. The slide is pivot jointed with workpiece carrier tray and engaged in guide seat. The adjustable eccentricity mechanism comprises a base which is connected with a power shaft of the motor, and a pivot shaft of base and linkage is eccentric to the power shaft. The power shaft drives the base rotating and the linkage swinging eccentrically, and the slide moves linearly according to the limitation from guide seat, and a horizontal radial vibration and low frequency vibration is generated on the workpiece carrier tray, so the low frequency vibration is generated on the surface of the workpiece which is touched with the polishing disk.

A light guide lens includes a lens body having a light incidence surface and a light emission surface, a plurality of refraction structures formed on the light incidence surface, and a plurality of reflection structures formed on the light emission surface. The refraction structures send incoming light rays to the light emission surface by refraction. Each of the refraction structures turns incoming light rays coming in all directions into refracted parallel light rays. The refracted parallel light rays arriving from the refraction structures reflect off the corresponding reflection structures and then laterally exit the lens body. The refracted parallel light rays arriving from each of the refraction structures travel to a corresponding one of the reflection structures, such that eventually the incoming light rays exit laterally. The present invention further provides a light emitting diode package structure having the light guide lens.

An apparatus for homogeneously distributing lights includes a light guide plate, an incidence microstructure and an emergence microstructure. The incidence microstructure is arranged on a surface of the light guide plate and opposite to a light source. The emergence microstructure is arranged on a surface of the light guide plate opposite to the incidence microstructure. The lights emitted by the light source pass through said apparatus thereby being homogenously distributed. Thus the manufacture costs are lowered, and the light source utilization ratio is increased.

The present invention discloses a dual-lens hybrid diffractive/refractive imaging system comprising: a first lens including a concave surface and a convex surface; and the second lens including a convex surface and a concave surface. The concave surface of the first lens is an objective surface facing the object. The convex surface faces the convex surface of the second lens, while the concave surface of the second lens faces the charge-coupled device (CCD) through a filter. Any surface of the first lens and the second lens is spheric or aspheric. Moreover, the imaging system comprises at least one diffractive surface, referred to as a hybrid diffractive/refractive surface, formed on any surface of the two lenses. Therefore, aberration is eliminated and image quality is improved without increasing the number of lenses.

A multistage pump includes a shaft assembly and a housing and spacing plates. The shaft assembly completed by forming shafts and rotors integrally. The spacing plates defining a plurality of successive compression chambers, each chamber is delimited by two symmetrical spacing plates, there has a ring groove associated with the spacing plates, and having an elastic component placed. When the elastic component pressed by the housing, it became leakage and the clearance between the rotors and the spacing plates be easily controlled, by this way, the pump using parts are easy to manufacture, can be machined accurately and which enable highly accurate assembly to be achieved. As to the assembling method, which is characterized by mounting the high pressure end axial bearing seat and the high pressured end plate, then to control the clearance between the high pressure end plate of the bearing seat and the rotors. Furthermore, to install the spacing plates and the housing make the compression chamber formed.
