A high enthalpy wind tunnel, with Huels type DC-arc heater, is improved to 54kVA(49kW) input power source and its characteristics are investigated. In the case of arc heated flow, the mass flow rate m, the stagnation pressure po, the discharge current I and the voltage V are measured by experimentally by comparing these results of 27kVA(24.5kW) input power in this arc heater. The stagnation temperature To was not measured, however a method of estimating it from m and po with the aid of the high temperature air tables, is proposed by assuming isentropic flow. In the present experiments, the average value of stagnation temperature are evaluated about 2000K ～ 2500K. K.Kindler's graph, for the electric resistance V/I versus the similarity parameter I^2/m are plotted from the present data for air, in addition another data of Huels, Hybrid and segmented type arc heaters are compared to the present data. 2003-01-19T15:00:00Z http://hdl.handle.net/11133/1613 タイトル: 高効率ジルコニア固体電解質型燃料電池の開発(I) : 高性能スカンジア安定化ジルコニア固体電解質 著者: 平野, 正典; 織田, 隆之; 渡邉, 慎治; 鵜飼, 健司; 水谷, 安伸 抄録: Sc_2O_3 (scandia)-doped cubic zirconia electrolyte with high electrical conductivity sintered at low temperature and scandia-doped tetragonal zirconia electrolyte having improved mechanical strength were developed. 1 mol% Bi_2O_3-10 mol% Sc_2O_3-doped zirconia with cubic structure sintered at 1200°C had sufficient conductivity of 0.33 S/cm at 1000°C and did not show cubicrhombohedral phase transformation. Dense zirconia ceramics fabricated by sintering at 1300℃ for 1 h in air followed by hot isostatic pressing (HIP) at 196 MPa at 1450℃ for 1.5 h in an Ar gas atmosphere, which consisted of submicrometer-sized grains of tetragonal phases and were stabilized with 5 and 6 mol% Sc_2O_3, exhibited high strength (1330 MPa and 1140 MPa, respectively) and good conductivity (0.15 S/cm and 0.18 S/cm at 1000℃, respectively). 2003-01-19T15:00:00Z http://hdl.handle.net/11133/1614 タイトル: 集風による高効率風力発電の検討 著者: 申, 真淳; 雪田, 和人; 後藤, 泰之; 一柳, 勝宏; 日下部, 哲朗 抄録: Effective utilization and high-efficient power generation method of natural energy are widely studied for the global environmental protection. Recently, as one of them, the power generation method of environmental harmony type is noticed , and the wind power generation of small size and photovoltaic power generation are introducing widely in each home. However, it must be greatly dependent on the wind which is a natural phenomenon on the installation of the wind power generator. Therefore, enough examination is necessary on the installation point. In this paper, collection wind technique for the purpose of the high-efficient utilization of wind power generator is proposed. The examination is carried out by the computer simulation in respect of the effectiveness of proposal technique. Concretely, it is reported referring to the Aichi Institute of Technology campus model. The computer simulation using finite element method is carried out for selecting the effective point of collection wind. 2003-01-19T15:00:00Z http://hdl.handle.net/11133/1615 タイトル: キャピラリー電気泳動法による整腸薬の分離分析 著者: 酒井, 忠雄; 手嶋, 紀雄; 真弓, 聡; 安藤, 尚宏; 大野, 典子 抄録: Atropine, berberine and acrinol were separated and analysed by capillary electrophoresis. Several modifiers such as sodium dodecylsulfate and ethanol were added to the electrophoretic buffer solution (20 mM sodium borate, pH 9.2) to improve the separation of the three compounds. These compounds were successfully separated within 13 min by using a 72 cm × 50 μm i.d. fused-silica capillary at30kV. The detection was done at 200 nm. The calibration graphs were straight lines over the range 0.5 - 2.0 × 10^<-4> mol 1^<-1> for each atropine, berberine and acrinol.
