These formulas consider the experimental factors including the section size of specimen, the pitch of hoops (proportional pitch), concrete strength and yield strength of hoops. The results from the formulas agree well with the test results. 1998-03-30T15:00:00Z http://hdl.handle.net/11133/1064 タイトル: HTTPプロクシを利用した代理サーバの設計 著者: 杉浦, 敦也; 羽賀, 隆洋 抄録: Today, many organization and person are offering service by way of Internet or other network, and using some security system to save their system from what they don't want. But, almost security system used in today restrict to user to save the system. Usually, it's restrict to service that user usually don't use. But, that service is sometime necessary. Now, I pick up a firewall, that's one of the such security system. Usually, they use proxy server to communicate beyond the firewall. But, they need permission to drive that on firewall host. There is case of limit to give a account or to ban to execute daemon process, to improv security level. Almost administrator offers proxy service for well known service such like WWW. But, They can't communicate using other service. In this paper, I make proxy server drive communicating each other using HTTP proxy running at Aichi Institute of Technology, and examine it. 1998-03-30T15:00:00Z http://hdl.handle.net/11133/1065 タイトル: 傍熱型光照射熱電子コンバータに関する研究 著者: 川口, 朋秀; 津田, 紀生; 山田, 諄 抄録: Thermionic generation is remarkable as one of new technology of generation of electricity in the future. It is one of direct generation, and it has many advantages. But a thermionic converter is not practically used yet. The thermionic converter generally works at high temperature. But it causes to shortening of emitter's life and problem of stability. To improve these problems the light is irradiated to the thermionic converter at lower temperature. In this experiment the thermionic converter of indirectly heated type is used, and the characteristic of output is measured. An accurate estimation of output density became to be possible by using the indirectly heated type. As a result of the experiment, it was founded that the higher output was obtained at the relatively lower temperature of emitter. 1998-03-30T15:00:00Z http://hdl.handle.net/11133/1066 タイトル: コンクリート塊のコンクリート用骨材としての利用に関する研究 著者: 久保田, 浩靖; 森野, 奎二 抄録: This study is aimed at clarifying basic properties of concrete using recycled aggregate obtained by crushing from demolished concrete. The concrete waste occurred from concrete struc-tures in Aichi prefecture was used as the material for producing recycled aggregate with a maxi-mum size of 20mm. The demolished concrete was crushed below 40mm by a jaw crusher and not polished in order to do aggregate. Therefore, demolished concrete debris (recycled aggregates) contain impurities (asphalt, and others), and the large amounts of cement paste or mortar adhere to its surface. The concrete made with the recycled fine and coarse aggregate was compared with the concrete used mountain pit sands and sandstone crushed stone aggregates. Aggregates in concrete were replaced the recycled coarse aggregate with sandstone crushed-stone aggregate of 0,30,60 and 100 percent. The concrete by use of the recycled coarse aggregate of 30% had the same good workability and strength as that of natural aggregates concrete. The study also clarified low strength and Young's modulus at 28 days of age, low neutralized depth, high ratios of length change after drying (RH 60%) for 54 weeks. Those results differed by mix proportion from 45 to 65% in water cement ratio. 1998-03-30T15:00:00Z
