Abstract: A hard water-repellent structure and a method for fabricating the same are provided. The method adopts an atmospheric pressure plasma deposition (APPD) technique to form a hard coating having a rough surface on a substrate, and form a water-repellent coating on the rough surface. Because the hard water-repellent structure includes the hard coating and the water-repellent coating, hardness, abrasion-resistance, transparency and hydrophobicity of the hard water-repellent structure are improved. The hard water-repellent structure protects the substrate from friction. Moreover, because the disclosure adopts the APPD technique to form the hard water-repellent structure, the cost of production is reduced dramatically. Thus, the disclosure can solve drawbacks of prior art.

Abstract: A plasma head and the plasma-discharging device using the same are disclosed. The plasma-discharging device comprises a power supply with two electrode terminals. The plasma head comprises: an outer electrode having a chamber formed therein; an inner electrode, disposed inside the chamber; and a flow guiding structure, disposed inside the inner electrode; wherein the outer electrode and the inner electrode are connected respectively to the two electrode terminals of the power supply; and the flow guiding structure further comprises at least an inlet for introducing a working fluid into the inner electrode and at least an outlet being communicated with the chamber of the outer electrode to guide the working fluid to flow into the chamber of the outer chamber.

Abstract: A fixed support for voice coil motor comprises a coil, hollow plate, opening, structural reinforcement beam, and a plurality of pins. The pins extruding from the hollow plate allows the coil to wind around them. The opening, which locates on the center of the hollow plate, distributes stress concentration around the center. The structural reinforcement beam, which extrudes from an edge of the hollow plate, improves stiffness of the fixed support, thereby allowing the hollow plate to be made thinner.

Abstract: A solder head control mechanism which uses a movable small size and simply structured acoustic coil linear servomotor to directly drive a solder head to perform soldering operation. The solder head links with a position sensor, a controller and a current output actuator to form a closed loop control mechanism which has small inertia, fast response time and great positioning accuracy. The controller may dynamically change amplifying value to actuate the solder head.
