Abstract: A structure of inkjet-head chip and a method for making the same are disclosed. Driven by the need of making a thin insulator layer to lower the working power of the inkjet-head chip, we separately manufacture a passivation layer and a second conductive layer. The passivation layer and the second conductive layer have to be formed from different materials. The defining means for the passivation layer and the second conductive layer have high selectivity and do not overetch or damage the structure of inkjet-head chip.

Abstract: A light-emitting diode (LED) structure and a method for manufacturing the LED structure are disclosed for promoting the recognition rate of LED chips, wherein a roughness degree of the surface under a first electrode pad of a first conductivity type is made similar to that of the surface under a second electrode pad of a second conductivity type, so that the luster shown from the first electrode pad can be similar to that from the second electrode pad, thus resolving the poor recognition problem of wire-bonding machines caused by different lusters from the first and second electrode pads.

Abstract: A loop type heat dissipating apparatus with a sprayer for use in heat transfer between a heat source and a heat sink includes an evaporator, a condenser, and a working fluid. The evaporator contacts the heat source and includes a first chamber, a second chamber, and a sprayer disposed between therebetween. The condenser contacts the heat sink and includes a third chamber communicating with the second chamber and a wick structure disposed on one side of the third chamber. The working fluid fills the loop type heat dissipating apparatus and is turned into microdroplets via a sprayer. The sprayer impinges the microdroplets into the second chamber where the microdroplets are then evaporated by the heat source before proceeding to the third chamber for condensation, liquefaction and adhering to the wick structure. Eventually, the working fluid flows back to the first chamber under a pumping force actuated by the sprayer and completes the cycle.

Abstract: A spraying device for atomizing a liquid is proposed. The spraying device includes a nozzle plate and an actuator. The nozzle plate is provided with a plurality of nozzle apertures. Each of the nozzle apertures includes an entry end for the liquid to enter and an exit end for the liquid to exit. The entry end and the exit end of at least one of the nozzle apertures are asymmetrical structures. The actuator is integrated with the nozzle plate to actuate atomization of the liquid. The spraying direction of a liquid droplet after the liquid is atomized can be controlled by modifying the shape of the exit end of the nozzle aperture.

Abstract: A micro-spray system resonance frequency modulation method and device designed to minimize resonance frequency drift during atomization involves using a resonance frequency modulation unit for modulating resonance frequency and nodes, controlling and calibrating resonance frequency, and performing real-time measurement and correction to prevent operating frequency from drifting beyond a preferred operating frequency range, with a view to increasing spray flow and spray area, minimizing effects of ambient factors, and overcoming drawbacks of prior art.

Abstract: A nozzle plate suited for a droplet generator is provided. The nozzle plate includes a nozzle layer and at least one filler. The nozzle layer has a nozzle and at least one trench. The nozzle passes through the nozzle layer. The trenches apart from the nozzle are formed on a surface of the nozzle layer around the nozzle. The filler is filled in the trench. The wetting angle of the surface of the filler is different from the wetting angle of the surface of the nozzle layer. The nozzle plate has higher surface wear resistance and lower probability of jamming at the nozzle.

A conductive layer is formed on the heating layer, and includes a notch therein to define a heating area. A chamber for storing liquid is formed on the heating area, and includes a first side and a second side. The first side faces the heating area, and the second side is connected to the first side. The chamber is formed with an exit, from which the liquid is dispensed, on the second side. The porous material is disposed on the chamber, and the liquid flows to the chamber through the porous material.

Abstract: A porous back-shooting inkjet print head module is disclosed. The ink permeates through the porous ink supply layer into an ink chamber in contact with the outside by an injection hole, and the porous ink supply layer prevents the ink from flowing back. Therefore, the ink chamber is sealed very well and more pressure could be generated. The invention can thus be used for inks with high viscosities. It does not need a precision alignment process as in the prior art. This does not only increase the efficiency and yield of production, but also reduces the cost.

Abstract: A multi-functional conditioner set for a chemical-mechanical polishing station. The multi-functional conditioner set has at least two conditioning heads each made from a different material such as diamond dust and nylon. The multi-functional conditioner set also includes an ejection tube for delivering chemical agents and de-ionized water to the conditioning heads. Moreover, a vibrator is attached to the ejection tube to transmit ultrasonic or megasonic vibration to the chemical agents and de-ionized water. The conditioning heads can be arranged in various combinations and the ejection tube set to various control settings. Hence, a polishing pad can be cleaned or reconditioned and residual diamond particles on the polishing pad can be removed. Furthermore, the conditioner set occupies only a single area above the polishing table of the polishing station.

Abstract: A collapsible easel with a panel standable on an uneven ground includes an easel consisting of three tripod feet adjustable in length and collapsible to be contained in the panel consisting of two cover plates pivotally connected to each other. A first cover plate has a handle on an outer side and three position pivot bases in an inner wall of the outer side for pivotally connecting with upper ends of the tripod feet, which are separable to let them be contained in the first cover plate. Then the second cover plate is folded on the first cover plate to become a flat case having small dimensions and having light weight for transporting and storing. The tripod feet can be adjusted in length by means of a movable rod movably contained in each tripod foot. Thus the tripod feet can stand on an uneven ground by adjusting each tripod foot, and also can suit to different persons using this easel with a panel.

A spring may bias the switch button away from the supporting surface for allowing the switch button of the sound generating device to be actuated and depressed to energize the sound generating device when the base is depressed toward the supporting surface against the spring.

Abstract: A hinge for temples of eyeglasses has a sidewise rectangular block extending sidewise from its body to fit in a hole of a bent projection of a lens rim, and an ear with a threaded hole at the rear end for a screw to engage. The screw also engages with a threaded hole of an ear at the front end of a temple so that the hinge may be combined with the temple. And the sidewise block of the hinge has several slanting saw-teeth on two opposite vertical sides to engage the walls defining the hole of the bent projection of the lens rim after the block is fitted in the hole so that the hinge may be firmly combined with the lens rim.
