The Change of the Samurai's Premises in Edo-machi and Otsukaiban-cyo -A Study on the Samurai's Premise of the Fukui Castle Town, Part19-
Get PDFThis paper considers the change of the samurai's premises in Edo-machi and Otsukaiban-cyo, referring to the 'FUKUI JOUKA-EZU'. Kami-Edo-machi and Naka-Edo-machi was performed allotment of the premises with the marriage of 'KATSUHIME' in Keicho 16 years. There were many premises substitutes of Kami-Edo-machi immediately after 'KATSUHIME' migrated to Edo for Genna 9 years. The allotment of the premises site of Otukaiban-cyo had a big changed after the salary reduction of Jokyo 3 years. In Otukaiban-cyo the Keicho era Otsukaibans a lot pf lived, however the mansions of the Otsukaiban disappeared all after Jokyo 2.departmental bulletin pape
Actually report about the engineering of requirements and the definition of requirements on the systems construction
Get PDFThe efficiency of the IT project of the company is demanded now. There are a lot of cases that most of project breaks are caused by the definition of requirements is connected by the whole of the systems construction for a quality improvement and a cost cut. This study aimed for improvement of the efficiency from the standpoint of the demand engineering.departmental bulletin pape
Disaster Detection of the Iwate-Miyagi Nairiku Earthquake in 2008 by using Satellite Remote Sensing
Get PDFThe Iwate-Miyagi Nairiku earthquake of magnitude 7.2 on the Richter scale occurred in the Tohoku district in Japan on June 14, 2008. It caused many landslides, debris flows, etc. in the mountainous area. This paper describes the detection and analysis of seismic disasters in Iwate prefecture and Miyagi prefecture by using the satellite data of ALOS-PRISM/AVNIR-2/PALSAR. True-color, false-color, NDVI and pan-sharpen- true-color images are made by using AVNIR-2 and PRISM data. The composite color image, in which R is the PALSAR image after earthquake, and G and B are the PALSAR images before earthquake, is made. Main target sites are Aratozawa-dam area which was seriously damaged by the landslide, and Komanoyu-onsen area which was attacked by the huge debris flow from Mt. Higashi-Kurikoma.departmental bulletin pape
Summary of the Field Survey on the damage of bridges in the 2011 off the Pacific Coast of Tohoku Earthquake
Get PDFThe off the Pacific Coast of Tohoku Earthquake (Mw9.0) occurred in Tohoku Province (including Tokyo Metropolitan area), Japan, at 14:46 on March 11, 2011. The number of victims and missing people was nearly 20,000. JMA seismic intensity 7 was recorded in Kurihara city. Damage of some bridges which were located on the coast were developed by great tsunami. On the Kesen Bridge which is located in Rikuzen-Takada, the superstructure washed away by tsunami. Based on the field investigation, damage of some typical bridges and their restoration (after seven months, October, 2011) are presented in this report.departmental bulletin pape
Change of Structure in Carbon Steels by Heat Treatment
Get PDFWe examined the change in metallurgical structure of cold-rolled carbon steels by heat-treatment. Specimens were three kinds of carbon steel of S10C, S25C and S50C. After repeating cold-rolling and heat-treatment at 700℃ or 900℃ in the atmosphere, the steel sheets were about 2mm in thickness. The oxide film on the surface was removed by mechanical abrasion, and the steel sheets were heat-treated at 700℃ or 900℃ in a vacuum. The steel sheets were cold-rolled to 0.5mm in thickness, and cut in size of 5mm×20mm. After the heat-treatment at 100-900℃ in a vacuum, The chemical etched surface of the specimens was observed by using scanning electron microscope. And, we measured Vickers hardness and X-ray diffraction pattern for the heat-treated specimens. The change in metallurgical structure of the carbon steel specimens was discussed on the basis of the heat-treatment temperature dependence of the Vickers hardness and the half-value width of the Fe(311) X-ray diffraction peak obtained by analyzing the X-ray diffraction pattern.departmental bulletin pape
The design and manufacture of experimental apparatus for students (Forced excitation of one degree of freedom spring-mass system)
Get PDFWe report the design and manufacture of experimental apparatus for students. This experimental apparatus is aimed to be used in the experiments of forced excitation of one degree freedom spring-mass system. After a theoretical examination, experiments are made for confirmation. First, the frequency response curves are obtained theoretically. Second, the experiments are conducted with the new experimental apparatus. The experiment gives a good account of its nature not only qualitatively but quantitatively. It will be possible to obtain a value close to the theoretical result, if our students carry out their experiments carefully.departmental bulletin pape
Effect of chelating agents on preconcentration of trace heavy metals in aqueous solutions by thermoresponsive polymer-mediated extraction
Get PDFIn the preconcentration of trace heavy metals in aqueous solutions with poly (N-isopropylacrylamide) (PNIPAAm), the effect of chelating agents on the enrichment of analytes was investigated. The use of 8-Quinolinol (Oxine) instead of ammonium 1-pyrrolidinedithiocardamate (APDC) enabled ca. 80-fold and 56-fold enrichment for Cr and Cu, respectively. The preconcentration factors improved compared to previously obtained values by using APDC (ca. 38 fold for Cr and ca. 44 fold for Cu). This enhancement seems to be due to the decrease in the loss of metal chelates during the measurement of graphite-furnace atomic absorption spectrometry. Since the loss, however, cannot be completely suppressed even by using Oxine, further investigation such as the use of different chelating agents is required for practical applications of the proposed method.departmental bulletin pape
A study on the situation of power generation in Japan
Get PDFWe studied the present and future situation of the power generation in Japan, from the view point of the issue of the fossil fuel depletion and the global warming, the accident of Fukushima nuclear power plant, the substantial introduction of alternative energy such as photovoltaic power, and the influence of the energy situation changes on Japanese industries and society. We also analyzed and characterized the power generation systems such as thermal power plant, nuclear power plant and photovoltaic power plant by using the index of the utilization rate of the plants. The utilization rate is determined by counting the time of periodical inspection and trouble shutdown, the decrease of operation rate corresponding of daily and seasonal demand variation, and weather dependence in case of photovoltaic and wind power generation.departmental bulletin pape
