Polystyrene (PS)-based hybrid particles containing a large amount of Mg(OH) 2 powder treated with methylhydrogen polysiloxane (MHS) were fabricated by a bulk and subsequent suspension two-step polymerization method. All the particles fabricated showed spherical shape and their particle sizes were about 500 μ m, irrespective of the additive amount of the Mg(OH) 2 powder modified with MHS (ST-1). The actual content of ST-1 powder incorporated inside each kind of hybrid particle was almost the same as that in the raw mixture, and agglomeration of ST-1 powder was hardly observed inside the hybrid particles. The compressive strength of the hybrid particles remained almost unchanged, even when the ST-1 powder content increased from 10 to 50 phr. Furthermore, a composite fabricated by employing the hybrid particles achieved homogenous distribution of ST-1 powder and showed a higher oxygen index than that of a composite fabricated by directly mixing of PS pellets and ST-1 powder.

We investigated channel estimation with scattered pilots (SPs) in digital terrestrial television broadcasting (dTTB) and the performance of a receiver with a two-dimensional (2d) filter. High-accuracy interpolation is necessary because we perform channel equalization with SPs, which are inserted in transmit signals nonrectangularly. This interpolation is performed with a 2d filter that has a nonrectangular spectrum. However, the generation of the 2d filter involves heavy computational complexity. We propose a method of reducing the computational complexity by designing separable 2d filters. In addition, we present simulation results that compare our method with some conventional methods and show its effectiveness

Low-temperature and rapid solid-state synthesis of YAG:Ce powders using oxides with narrow particle size distribution

We applied a new precipitation technique to the syntheses of CeO 2 and Y 2 O 3 as starting oxides for YAG:Ce powders. This technique can be characterized by usage of NH 4 Hco 3 as a precipitating agent and by aging of the precipitant at 80°C for 3 hours. Gibbsite (Al(OH) 3 ) was used as an Al source. The particle size distribution of CeO 2 synthesized by this process was very narrow, and was in the sub-micrometer range. Y 2 O 3 particles, whose sizes ranged from 0.2μm to 10μm were larger and broader in distribution than CeO 2 . Gibbsite, which transforms finally into Al 2 O 3 also had a narrow particle size distribution from 0.3μm to 3μm. X-ray diffraction pattern of YAG:Ce powder synthesized from these (hydr)oxides at 1400 °C for 5 hours in air showed the material is monophasic. The best luminescent intensity, excited by blue light, was obtained in 1.5mol% Ce-doped YAG:Ce phosphor (Y 2.955 Ce 0.045 Al 5 O 12 ) and is comparable to that of materials synthesized by the citric-gel method using metal nitrates as starting materials and firing at 1400 °C for 5 hours in air.

This paper presents a solution for the hardware implementation of EIA-709.1 control Networking Protocol. It is the basic protocol of LonWorks systems that is widely used for the building system and the sensor system. The EIA 709.1 protocol has been implemented at the hardware level from physical layer to network layer to reduce the computing load on the CPU. VHSIC hardware description language (HdL) has been used for the EIA-709.1 protocol. Other layers have been implemented using C programs on Intel 8051 processor. The EIA-709.1 protocol has been implemented using field programmable gate array (FPGA) technology and the commercial feasibility of the proposed solution has been performed through the communication test using the Neuron Chip of EIA-709.1 protocol. The designed EIA709.1 core is usable as one of the intellectual properties (IPs) and it is applicable to design System-on-a-Chip (SoC) for various industrial controllers.

Tensile and plain fatigue properties of β type titanium alloy, Ti–29Nb–13Ta–4.6Zr, which underwent various thermo-mechanical treatments, were investigated in order to judge its potential for biomedical applications. Microstructures of Ti–29Nb–13Ta–4.6Zr (TNTZ) aged directly at 723 K for 259.2 ks after cold rolling and TNTZ aged at 723 K for 259.2 ks after solution treatment are composed of precipitated α phase in β phase. While, microstructures of TNTZ aged directly at 598 K and 673 K for 259.2 ks after cold rolling and aged at 598 K and 673 K for 259.2 ks after solution treatment are composed of precipitated ω phase, and precipitated α and ω phases in β phase, respectively. Tensile strength of aged TNTZ after solution treatment and aged TNTZ after cold rolling decreases with increasing aging temperature although the elongation shows the reverse trend. TNTZ composed of ω phase or ω and α phases in β phase shows the tensile strength of around 1000 MPa or more. Young's moduli of aged TNTZ after solution treatment and aged TNTZ after cold rolling decrease with increasing aging temperature. TNTZ conducted with solution treatment has the lowest Young's modulus of around 60 GPa. Fatigue strengths of aged TNTZ after solution treatment and aged TNTZ after cold rolling increase with increasing aging temperature. In particular, TNTZ aged directly at 723 K after cold rolling shows the greatest fatigue strength in both low cycle fatigue life and high cycle fatigue life regions, and the fatigue limit, which is around 770 MPa, is nearly equal to that of hot-rolled Ti–6Al–4V ELI conducted with aging, which is one of representative α + β type titanium alloys for biomedical applications.

Modification of the carbide characteristics through the grain boundary serration is investigated, using an AISI 316 and 304 stainless steels. In both steels, triangular carbides were observed at straight grain boundaries while planar carbides were observed at the serrated grain boundaries. The serrated grain boundary energy is observed to be much lower than that of the straight one. Therefore, the carbide morphology is found to be changed from triangular to planar along the serrated boundary to reduce the interfacial energy between the carbide and the matrix. The creep-fatigue properties of these steels at 873K have been investigated. The creep-fatigue life of the sample with planar carbide at the serrated grain boundary was found to be much longer than that with triangular carbide at the straight one. These results imply that the planar carbides with lower interfacial energy have higher cavitation resistance, resulting in the retardation of cavity nucleation and growth to increase creep-fatigue life.

For the first time, low-k dielectric ALd-SiBN (Atomic Layer deposition) is successfully developed and applied on poly-Si/WSix gate as a spacer for reduction of parasitic capacitance between the cells. ALd-SiBN deposition is performed at 630°C using dichlorosilane (SiH2Cl2-dCS), boron-trichloride (BCl3) and ammonia (NH3) as precursors. compared with the conventional silicon nitride, ALd-SiBN exhibits similar film properties at lower dielectric constant. ALd-SiBN layer is deposited on poly-Si/WSix stack gate in 90nm NANd flash device. A significant reduction (>15%) of the floating-gate coupling voltage is achieved by employing SiBN compared with SiN spacer. In addition, excellent data retention characteristics (@HTS) is identified by applying lowk dielectric SiBN layer as a spacer on 90nm NANd flash device. © 2004 IEEE.
