Abstract:
A manufacturing method of ladder-like phosphorus-containing polysilsesquioxanes nanocomposite material is disclosed. The method uses a reaction between ladder-like phosphorus-containing polysilsesquioxanes and modified epoxy. Besides improved char yield and limiting oxygen index, thermal degradation rate of the nanocomposite material is lowered dramatically so that the nanocomposite material possesses excellent flame retardance and thermal stability. Moreover, optical transparency of the nanocomposite material according to the present invention is still good, not being reduced by increased amount of polysilsesquioxanes. Thus the nanocomposite material is applied to decorative paints or protective paints.
Abstract:
The present invention relates to a transmission system with interference avoidance capability, which includes a transmission apparatus and a receiving apparatus. The transmission method thereof receives first data by means of an interference-processing module of the transmission apparatus and adds a plurality of extension data to the first data to produce second data for replacing a plurality of data corresponding to an interfered band in the second data with zero data, and then producing transmission data. The transmission data is converted to a radio-frequency signal by a transmission-processing module and transmitted to the receiving apparatus. Thereby, signal interference can be prevented by avoiding spectrum overlap regions.

Abstract:
An angle-laminated composite tube with double layer of materials uses an inner layer material and an outer layer material with different functional properties. The two materials are cut into a plurality of slices in a specific shape. They are laminated alternately with a mismatching angle inside a mold with a specific angle to form a laminated assembly. Finally, a hot press is used to cure the laminated assembly into a structure with an inner layer, an outer layer, and an interlacing layer. The slice shape of the inner layer material and the outer layer material is specifically designed so that the inner layer, the outer layer, and the interlacing layer receive an even pressure during the curing process, rendering desired densities in the layers. The angle-laminated composite tube can achieve a high structural strength, with the inner and outer parts satisfying different functional needs.

A manufacturing method for wide-range fine-grained magnesium alloy thin-sheet material is disclosed. The method includes an extrusion process and a rolling process. By the plastic deformation feature of the two processes, the wide-range fine-grained magnesium alloy thin-sheet material that satisfies the requirement of cases of 3C products with thickness of less than 1 mm is produced. Thus the method overcomes shortcomings of a conventional method that produces the material by a plurality passes of processes. Therefore, the manufacturing cost is reduced and the method is able to be applied to various industries.

The present invention relates to a multiple-input-multiple-output (MIMO) wireless transmission system and a transmission method thereof. A wireless transmitting system thereof receives encoded data via a first processing unit, which processes the encoded data and outputs the encoded data to a plurality of modulation units for modulating the encoded data to produce a plurality of modulated data. A plurality of first conversion units converts the plurality of modulated data to a plurality of transmitting signals. A plurality of radio-frequency (RF) circuits receives the plurality of transmitting signals and transmits RF signals according to the frequency-hopping sequence of a piconet. A plurality of receiving processing units of a wireless receiving system according to the present invention receives the RF signals, respectively, according to the frequency-hopping sequence of the piconet and transmits to a plurality of second conversion units for converting the RF signals to received data. A switching circuit switches the received data according to the frequency-hopping sequence of the piconet. A plurality of demodulation units demodulates the switched received data to produce demodulated data. A second processing unit received the demodulated data, and processes the demodulated data to output demodulated data. A decoding unit decodes the demodulated data output by the second processing unit to produce output data.
