Abstract:
The present invention discloses a high-temperature stable, low density and transparent silica aerogel prepared by carrying out a sol-gel process of a mixture containing a main precursor of inorganic siloxane and a high-temperature stable precursor to form a wet gel, wherein the high-temperature stable precursor and the main precursor undergo covalent-bond crosslinking; aging and supercritical drying the wet gel to form a low density, tough, hydrophobic silica aerogel of a porous network structure. The hydrophobation of the aerogel of the present invention prevails after several times of heating at 500° C., and the structure of the aerogel will not collapse caused by moisture.
Abstract:
A low profile card reading device is disclosed to include a first interface having a plurality of contact terminals movably exposed to the outside for connection to a computer, an interface controller coupled to the first interface to execute signal conversion and protocol operation of the first interface, a memory card slot for the insertion of a memory card, a card reading device controller respectively coupled to the interface controller and the memory card slot to transfer data from the memory card in the memory card slot to the computer and to store data from the computer to the memory card in the memory card slot.
Abstract:
A method for coloring an object engraved with gray level affect comprises steps of: storing an original draft of an image to be engraved as an image file, converting the image file into a gray level image; engraving an the object engrave according to the gray level image so that the object present a gray level effect; converting the image file into a modified color image; transferring the color image into a transfer paper to be as a colored transfer paper drawing; adhering the transfer paper on a surface of the object to be engraved; heating and pressing the object so that the dyes of the transfer paper are transferred to the object; removing the paper and transferring the object to an oven for heating so that the dyes on the object are fully combined with the object; and taking the object from the oven.
