Edging of slab is an important process to reduce and control width in the roughing area of hot strip mills. Width reduction amount that is required for edger in every pass is computed in the form of a very complicated on-line computer model. The model which previously was used for computation of width in roughing stri…
パルププロセスに於いて繊維特性の測定には，プロセス制御やパルプの最終品質を解析するツールであるという主たる役割がある。新手法の測定方法による分析計は，ブローラインから最終パルプに至る，クラフトパルプに対する初めてのオンライン分析計となる。シャイブに関する情報はクラフトパルプ生産に於いて，パルプの高品質化や薬品コストの低減を可能にし，同時に，繊維長や繊維幅等の重要な原料情報もオンラインで得る事が可能となる。カール，キンク及びファイン測定によって，プロセスのファイバー品質に対する影響を確認する事ができる。広葉樹（HW）クラフトパルプに於いて，ベッセルは印刷に関する品質問題の一因となり，故に，マーケットパルプのベッセル含有量やサイズ分布…
The soft magnetic Fe 73 Si 16 B 7 Nb 3 Cu 1 (at%) powder with nanocrytalline structure and the dielectric BaTiO 3 powders with different sizes and shapes were mixed to be cast as the absorbing sheets with polymer-based binders and solvent. Absorbing properties, such as complex permittivity and complex permeability of…
GaN-based LEDs and laser diodes have become the devices of choice for optoelectronic applications operating in the shortwavelength range. One of the remaining challenges for improving GaN-based LEDs is to reduce their optical losses, which are caused by the high refractive index of GaN (∼ 2.5).1 To overcome this diffi…
We have proposed a numerical methodology termed pixel mapping (PM) method on the basis of crystallography. The PM method can characterize various defects in 24 prototypes cubic crystals listed in the Strukturbericht database. It identifies point defects, linear defects, planar defects (including antiphase domains in c…
We have prepared pyrolytic carbon samples from triethylamine and investigated their yields and magnetic properties. Ferromagnetic samples were obtained from the pyrolysis products even at room temperature. The yield of the ferromagnetic sample was increased by setting a magnetic circuit on the pyrolysis chamber. The m…
The exciton condensation in a Si1−x Ge x solid solution layer of Si/Si1−x Ge x /Si heterostructures with the formation of electron-hole liquid has been investigated by low-temperature photoluminescence spectroscopy. In the temperature range above the critical temperature of the transition from an exciton gas to electr…
This paper discusses the optical characteristics of a nonpolar a-plane InGaN/GaN quantum well (QW) with different indium compositions, QW well widths, and injection carrier densities. We find that the larger indium composition and smaller well width make the energy separation of |Y〉-like state to |Z〉-like state larger…
Hexadiyne and Peroxy radicals are investigated by non linear, femtosecond, Four Wave Mixing (FWM) techniques. Both species are relevant in the context of first aromatic ring formation and ignition mechanisms, respectively. Recording spectrally dispersed fs-FWM signals unveils molecular features not accessible with the…
We report on experimental realization of different metal-dielectric structures that are used as surface plasmon polariton waveguides and as plasmonic metamaterials. Fabrication approaches based on different lithographic and deposition techniques are discussed.
We have carried out the project for the useful utilization of the remaining rice hull as an industrial carbon material. The rice hull carbon (RHC) powder is manufactured by carbonizing in a nitrogen gas atmosphere at high temperature, then crushing and sieving. The rice hull has a natural porous structure. The diamete…
メトラー・トレド社は従来にないコンセプトに基づいた新型のディジタルpH電極を開発した。このpH電極のセンシング部分は従来のガラス電極と同じ形状であるが，電極頭部に内蔵したCPUを含む電子回路でアナログ信号をディジタル信号に変換して専用の変換器にディジタル信号として送信できる機能を有している。従来のアナログ信号のpH電極ではpH値と温度の2つの信号しか出力できなかったが，新型ディジタルISM電極はpH値，温度の他に電極の状態を表すガラス膜抵抗，液絡部抵抗，使用経過時間，電極の劣化状態のほか，校正データまでも変換器に送信することができる。従来型のpH電極の場合，交換，洗浄などのメンテナンスを実施したときには，pH電極の設置現場での校正…
Novel dense and porous SiC-Si3N4/AlN composites were fabricated using a multi-pass extrusion process. In the 2nd and 3rd pass dense composites, the diameter of AlN fibers in the SiC-Si3N4 matrix was about 170 μm and 30 μm, respectively. The AlN fibers were refined in the SiC-Si3N4 composites with the increase of extru…
New dimeric porphyrin was synthesized as a result of coordination interaction between 2,3,7,8,12,13,17,18-octaethylporphyrinatozinc(II) and 5-(3,5-di- tert -butylphenyl)-2,8,12,18-tetraethyl-3,7,13,17-tetramethyl-15-(pyridin-4-yl)porphyrin. The new compound was characterized by spectral and TLC data, and equilibrium c…
Η παρουσία υπολειμμάτων ψυχοφαρμάκων στις πρώτες ύλες αποτελεί έναν από τους σημαντικότερους χημικούς κινδύνους για την ασφάλεια των έτοιμων γευμάτων παιδικών τροφών. Δεδομένης της υψηλής ευαισθησίας κατά το στάδιο της βρεφικής ηλικίας, έχουν τεθεί από την Ευρωπαϊκή Ένωση Ανώτατα Όρια Υπολειμμάτων (MRLs) για τις παιδι…
In the title complex, [Cd(C6H4NO3)2(H2O)4], the Cd II atom is situated on a crystallographic centre of inversion. The Cd atom shows a slightly distorted octahedral geometry and is coordinated by four O atoms from water molecules and two O atoms from deprotonated carboxyl groups of nicotinic acid Noxide ligands. The mo…
