Abstract: A radiation pattern insulator and an antennae system thereof are proposed. The radiation pattern insulator includes a dielectric substrate and a plurality of radiation pattern insulation elements. The dielectric substrate allocated between a plurality of antennae includes a top surface and a bottom surface, and a normal direction of the dielectric substrate is substantially perpendicular to propagation directions of electromagnetic waves radiated from the antennae. In addition, the radiation pattern insulation elements are allocated on the top surface or the bottom surface of the dielectric substrate, or alternatively, all allocated on the top surface and the bottom surface.

Abstract: A method for image sticking inspection of a light-transmissive device is disclosed. The light-transmissive device is responsive to application of a voltage to electrodes thereof to adjust light transmission characteristics. The method includes: providing light for passage through the light-transmissive device; applying a first alternating current (AC) voltage to the electrodes; applying a direct current voltage to the electrodes; and applying a second AC voltage to the electrodes, and measuring intensity of the light passing through the light-transmissive device during application of the second AC voltage.

Abstract: A method of manufacturing plastic foam powder puffs is provided. First, pluralities of plastic foam powder puff layers and adhesive layers are stacked, wherein the adhesive layers are applied between two adjacent plastic foam powder puff layers (sheets). Next, the adhesive layers are used to adhering the plastic foam powder puff layers together to form a plastic foam powder puff block. Next, the plastic foam powder puff block is cut in a vertical direction, while the first sheet of plastic foam is facing up, to obtain a plurality of plastic foam powder puff slices. Finally, the plastic foam powder puff slices are cut to obtain a plurality of attractive plastic foam powder puffs.

Abstract: A method of manufacturing powder puff is provided. First, a plurality of moulds of different sizes is provided. A smaller mould is used to form a powder puff block. Next, the powder puff block is placed into a mould cavity of a larger mould. Next, a different colored powder puff material charged into the mould cavity of the larger mould. Next, the different colored powder puff material and the powder puff block are heated after the powder puff material solidifies in the mould cavity to fuse the different colored powder puff material and the powder puff block to form a one-piece powder puff log. Next, the one-piece powder puff log is cut to obtain a plurality of pieces of raw-powder-puffs. The raw-powder-puffs are polished to obtain finished-puffs.
