Abstract: An axial-flow heat-dissipation fan including a frame and a blade wheel is provided. The frame has an inlet, an outlet, and an inner wall connected between the inlet and the outlet. The inner wall surrounding the blade wheel has at least one rough region. The blade wheel is rotatably disposed in the frame and located between the inlet and the outlet, and an air flows into the frame via the inlet and flows out of the frame via the outlet by rotation of the blade wheel. A gap exists between a blade end of the blade wheel and the inner wall. A laminar flow is generated at the gap when the blade wheel is rotating and the blade end passes through the rough region so as to prevent a backflow generated at the gap, wherein a flowing direction of the backflow is opposite to a flowing direction of the air flow.

Abstract: A field emission device has pixels with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light, giving the display the advantages of easy focusing, no dark spots, high brightness, and enhanced light emitting performance. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a high precision spacer to maintain a fixed distance between the cathode and the anode, enabling the device to be manufactured at reduced cost and high good yield.

In an embodiment, opposite trenches surrounding the microstructure are respectively etched on sides of the wafer, and the trench depth on the side of the wafer, on which the microstructure is, is equal to the design dimension of the microstructure. Contrarily, it is unnecessary to define the trench depth on the back-side of the chip. In the final step of the fabrication process, when the device is etched, such that the trenches on the sides communicate with each other to separate the microstructure from the whole wafer automatically and thereby shift from the etchant into the etching-stop solution to stop etching.

Abstract: An apparatus is provided for feeding fabric workpieces one at a time from the top of a stack of like workpieces having a first rough side and a second smooth side, the workpieces being stacked with alternating sides up. A computer controlled picker is used to separate the top workpiece from the remaining workpieces in the stack, and for depositing the workpiece on a downstream conveyor. An ultrasonic face detector is mounted above the first conveyor for determining whether the side of the workpiece facing the face detector--the top surface--is relatively rough or relatively smooth. A pivoting feeder/inverter is provided at the end of the first conveyor. If the workpiece has the desired side up for subsequent sewing operations, the inverter/conveyor is placed in a first position so that the workpiece is directed into a sandwich belt type conveyor which will not change the orientation of the workpiece.

Abstract: An automatic garment inspection and measurement system can create a two-dimensional or three-dimensional electronic representation of an object. This electronic representation can then be combined with other electronic representations to create a database of measurements from which standard patterns can be generated for use in manufacturing garments. The electronic representation can also be used to compare the manufactured object it represents to an ideal representation in order to determine if the object's measurements are within a predetermined tolerance of the ideal representation. A machine vision system is used to capture an image of the object and convert that image into a digital representation which can then be added to a database to be used to compile an ideal pattern or can be compared to an already existing ideal image to determine if the object is the correct size.
