摘要:
An improved structure of cooling tower includes a fan housing with a fan disposed therein, induction openings distributed on the fan housing and located below the fan, and a diffuser stack disposed at one end surface of the fan housing. In operation, cold air is drawn into the cooling tower by the fan through inlet openings of the cooling tower so as to exchange heat with the condensing water within a water chiller. When warm and wet air is drawn out of the cooling tower and the warm and wet air outside the cooling tower is induced in through the induction openings and then is drawn out, circulation reflux of warm and wet air, which tends to occur in conventional cooling towers, can be avoided and therefore increase the efficiency of the water chiller.

An electrohydrodynamic (EHD) condenser device includes a condenser installed with an EHD electrode. An electric field is generated upon a fluid of low conductivity inside a compressor device and an enhanced thermal conduction effect is then achieved since the electric field induces current convection, migration and deformity of bubble, increases perturbation and mixture of the flow field and eliminates boiling and delay. With the EHD utilized, size, weight, cost and required refrigerant amount of the condenser device are reduced. Further, thermal conduction efficiency of the alternative refrigerant is improved, making the EHD compensator device in compliance with associated refrigerant regulations made by CFC and achieve the purposes of environmental protection and energy saving.

The present invention provides a method for fabricating an implant stent with therapeutic effects. The method of the present invention includes designing and delineating a pattern of the implant stent, drilling a thin metal sheet to form positioning holes, cutting a desired pattern on the thin metal sheet according to the designed pattern, drilling a hole on a line rib of the stent to form a braided structure by a micro discharge processor according to the desired pattern. Then, the stent is cleaned and polished by the electropolish to trim the edge and the rough surface of the stent. Then, the biodegradable material, PLLA, PGA, fibrinogen, the polyurethane-polyethylene oxide mixed with the heparin or the combination thereof, is used for forming the mixed material with the high molecular weight, and is solved in a solvent, wherein another grinded therapeutic drug with the micro or the nano size is added. The drug can be As2O5, an anti-caner drug, or an anti-inflammation drug. The solution with the bioadsordable material having a therapeutic drug is atomized and sprayed on the outer and inner surfaces of the stent. Since a row of holes are arranged on the line rib of the stent, each hole is immersed into the solution due to the capillary phenomenon. When the solution is completely evaporated, the biodegradable and absordable material and the drug are coagulated to form a solid and to strongly coat on the surface of the stent. When the stent is implanted into a human body, the solid layer is slowly degraded and released on the injured site, so that the vessel is prevented from restenosis, and the therapeutic effect is achieved. The stent can be fabricated by the precision machine technology in Taiwan, so that the implant stent with low cost and therapeutic effects is obtained.

An electrohydrodynamic evaporator device (EHD) has an EHD electrode. An electric field is generated upon a fluid of low conductivity inside the evaporator device and an enhanced thermal transport effect is then achieved since a thermal boundary layer near a thermal transport surface is caused to have a greater perturbation while a very small voltage drop. With the EHD utilized, size, weight, cost and required refrigerant amount of the evaporator device are reduced. Further, thermal transport efficiency of the alternative refrigerant is improved, making the EHD evaporator device in compliance with associated refrigerant regulations made by CFC and achieve the purposes of environmental protection and energy saving.

摘要:
A miniature three-dimensional contour scanner is provided, which integrates the optical element and the set of optical lens of the optical projection module and the image capture module into a miniature measurement device. The device utilizes the optical fiber to guide in the light of outside light source and applies the digital micromirror device (DMD) chip to produce structured light pattern and project it onto the object's surface to be measured. The image sensor element is then used to capture the deformed structured fringe image, and by utilizing this information it is able to obtain the colored two-dimensional image and the three-dimensional contour size of the object. The miniature three-dimensional contour scanner can thus be applied in the measurement of miniature objects in the narrow space.
