中学校和歌学習指導でのWAKATONの活用
Get PDF情感豊かな鑑賞文を書くためには,適切な感性語を潤沢に使用することが必要である.筆者らは,中学校国語科の和歌の学習に和歌感性データベースを導入し,感性語に触れる機会を与えることで,感性語の習得を深めることを考えた(以下,Wakaton学習法---Waka Kansei technology supported online learning method---と呼ぶ).Wakaton学習法では,和歌の解釈に関するSD法を用いたアンケートが用いられる.これにより,生徒は,和歌の意味,解説,表現技法等を学習するだけでなく,より多くの感性語を学習する機会が与えられることが期待できる.実際の授業を通しての実証実験により,Wakaton学習法の導入によって,従来の指導法と比較して,生徒が鑑賞文中で使用する感性語の数と種類がより増加し,より情感豊かな鑑賞文を書くようになることが認められた.さらに,鑑賞文における感性語の使われ方と教師による鑑賞文の評価の間に,強い相関があることが認められた
Rolling contact fatigue investigation and experimental simulation for plastic film used for full - opening and partially - opening automatic ventilation greenhouses
Get PDFThe green house is widely used to add the quality and value of agricultural products. Newly developed full opening type green house has a lot of attracted attention because the roof opens and closes automatically in order to control the inside temperature. However, since the roof opens and closes very often, the cover sheet can be used only for 3-4months. This is because the plastic film is damaged between the support and rolling pipes during opening-closing affected by fatigue and wear. In this study, by using Scanning Electronic Microscope (SEM) and roughness test machine, the damage mechanism is investigated for the several plastic films. Then, FEM analysis is performed to evaluate the mechanical damage of plastic film between the pipes under different conditions and film materials. Also rolling fatigue experiments are performed to investigate the damage under different film materials. Then the results are compared with the FEM analysis. It is found that the thickness reduction of the film obtained under static contact analysis is the most important factor to control the damage of the film

Double gate IGBT with control of active hole injection: principle of low loss by numerical analyses
Get PDF電子デバイス/半導体電力変換 合同研究会, 10月29日-30日, 2015年, 長崎歴史文化博物館, 長崎県Double gate IGBT is proposed and confirmed significant reduction of turn-off loss with TCAD simulation. Conventional IGBTs have a problem of large turn-off loss with stored carrier in N-base. The proposed structure declines carrier injection during turn-off by dynamic hole injection decrease with the collector side gate control
Analysis of Intensity of Singular Stress Field for Bonded Cylinder in Comparison with Bonded Plate
No full textIn this paper, an intensity of singular stress field for a bonded cylinder is compared with the one for a bonded plate, which was obtained in the previous studies accurately. The analytical method focuses on the stress values at the interface corner edge obtained by performing FE analyses on the unknown and reference models which are subdivided by the same mesh pattern. It is found that this analytical method which is useful for analyzing the bonded plate cannot be directly applied to the bonded cylinder because the strain in the circumferential direction causes non-singular stress component affecting singular stress evaluation. In order to eliminate the non-singular terms, they are expressed explicitly from the interfacial continuity conditions and the stress-free boundary conditions at the interface corner edge. Since the intensity of singular stress field for the bonded cylinder cannot be controlled by Dundurs' parameter uniquely, the maximum and minimum values of the intensities of singular stress field are shown in the table and the chart according to Dundurs' parameter. There are cases where the intensity of singular stress field for the bonded cylinder is one and a half times as large as that for the bonded plate even if the practical materials are combined
Electric field induced effects in Y3N@[C80]6- anionic solid
Get PDFBy measuring the i−vi−v characteristics of Y3N@[C80]6− anionic solid at various temperatures and electric field strengths, four conducting phases with i∝vi∝v , i∝v2i∝v2 with low resistance, i∝v4i∝v4 and i∝v2i∝v2 with high resistance were observed. First, at temperatures below 100 K and field strengths below 30 Vcm−1Vcm−1 , the current passing through the sample was a linear function of the d.c. bias voltage due to free moving charges. Second, at the same field strengths, the trapped carrier was thermally activated with activation energies of 13.6 meV for temperature range of 100−250100−250 K and 88.7 meV for 250−450250−450 K. In this conducting phase, the carrier transport was governed by space charge limited conduction mechanism. Third, when the electric field increased from 30 to 120 Vcm−1Vcm−1 , the ii became a quartic function of the vv because the carrier mobility is a quadratic function of the field strength. A conducting phase with high resistance was observed at temperatures below 100 K. The trapped carrier was thermally activated with activation energies of 146.5 meV for temperature range of 100−250100−250 K and 288.5 meV for 250−450250−450 K. Finally, in the electric field strengths of 120−2000120−2000 Vcm−1Vcm−1 , a high resistance phase appeared in the anionic solid at temperatures below 100 K. The current was a quadratic function of the d.c. bias voltage, and the carrier mobility was independent of the field strength
Some Notes on Fixed Point Theorems in ν-generalized Metric Spaces
Get PDFWe study ν-generalized metric spaces. We first study the concept of Cauchy sequence. We next give a proof of the Banach contraction principle in ν-generalized metric spaces. The proof is similar to the proof of the original Banach contraction principle in metric spaces. Also, we give proofs of
