Development of a magnetic susceptibility measurement system for detecting the Meissner effect
Full text linkapplication/pdfTo identify the superconducting phase transition at low temperatures, we construct a measurement system for detecting the Meissner effect. The well-known method of the measurement system is the Hartshorn-type bridge, but we try to construct the simplified measurement system, where the cylinder of the primary coil and that of secondary ones are settle in a fixed geometrical arrangement without the Hartshorn-type bridge. In our study, we use an alternative magnetic field of HAC = H0sin(2πft) with H0 ~ 1.6 Oe and 12 < f < 4000 Hz. To test our measurement system, we measured the magnetic susceptibility of niobium and obtained very sharp and clear Meissner signal at around 8.2 K.departmental bulletin pape
A study on surface-condition changed and slip-coefficient subjected to cyclic loading of large displacement for High-strength-bolt friction joint.
Full text linkapplication/pdfContact points between two solids are very small we can’t make a sight in Figure 1. We focus on property of High-strength-bolt friction joint, and we propose Beam-Joint-Plastic-Hinge. We examine whether it correspond to Generalized Plastic Hinge. Beam-Joint-Plastic-Hinge is rolling mechanism utilizing slip behavior of High-strength-bolt friction joint, and its forming condition is slipping largely without transitioning bearing-type connection. When cycle large displacement occurs acting large tightening force by High-strength-bolt, surface asperity of friction surface will be broken. This is why state of steel material surface and slip-coefficient will be changed by repeated slip behavior. Plastic-Hinge-Moment which is defined as the moment at the joint when Beam-Joint-Plastic-Hinge is formed, is affected by slip-coefficient. We investigated relationship between state change of steel material surface and slip-coefficient through slip experiment. And disclosed the frictional surface which contribute to improve the evaluation precision of Plastic-Hinge-Moment.departmental bulletin pape
A study on width-thickness-ratio for Beam-Joint-Plastic-Hinge.
Full text linkapplication/pdfIn practice, plastic-hinge is evaluated by perfect elastoplasticity type shown in Figure l. But in fact, the stress increases while bearing gentle slope after expressing full plastic endurance. And if we use FA rank members which satisfy limitation of width-thickness-ratio, local backling will occur by accumulating plastic deformation. Under the circumstances, we propose Beam-Joint-Plastic-Hinge and aim for improving the evaluation precision of plastic-hinge. In this study, we focus on keeping base materials elastic when we introduce Beam-Joint-Plastic-Hinge and explain the possibility loosens limitation of width-thickness-ratio. At first, we show the design method when Beam-Joint-Plastic-Hinge is introduced. Next, we compare FA rank test specimen and FC rank test specimen.departmental bulletin pape
A Suggestion for Improvement of Artificial Intelligencethe Transition from J. Searle’s Model to J. L. Austin’s
Full text linkapplication/pdfThis paper reports our new idea as a suggestion for improving Artificial Intelligence, especially the field of “Utterance-Unit Tag.” Rapid technological innovation develops the high artificial intelligence in the area of discourse. To improve this area of skill more, such as adopting the “Utterance-Unit Tag” to the description of our actual, subtle utterances, AI researchers definitely need to classify the concept of “illocutionary forces,” proposed by J. L. Austin （1911-60）, more closely. Now the model based on J. Searle （1932-） ’s interpretation of J. L. Austin’s “illocutionary forces” is the generally accepted approach to developing AI discourse, according to previous research. Although Searle emphasizes our intention and function of the utterances, J. L. Austin’s model, however, is more appropriate because Austin focuses on not only verbal convention but also physical convention in his speech-act theory.departmental bulletin pape
Development of next-generation intelligent technology experiment system for education
Full text linkapplication/pdfThis equipment was developed and introduced with the support of the Ministry of Education 2020 private school facility maintenance subsidy. In order to apply for a grant for this equipment, our department set up a educational equipment working group, clarified the specifications for the operation purpose, operation requirements, functions and performance, and prepared the application in a short period of half a year from September 2019 to March 2020.
After applying to the Ministry of Education, we received an informal notification of the grant at the end of October 2020. After that, an order was placed with a contractor and the construction was completed at the end of March 2021.
In this paper, we explain the operation purpose, operation requirements, functions / performances, and development process of this equipment, and use it as a resource for the development of educational equipment in the future.departmental bulletin pape
Research on predictive steering and artificial steering Haptic for SBW
Full text linkapplication/pdfIn this research, we further developed the knowledge about the effectiveness of the method of evaluating the steering characteristics of the driver by the frequency component (PSD, Power Spectral Density) of steering, which is the research result of Reference (4), and for predictive steering in the SBW system. By expressing the inertial reaction force from the vehicle by the frequency component (PSD) and superimposing that component on the steering reaction force (Haptic), the state (reaction) of the vehicle can be expressed in the same way as the conventional steering system with mechanical coupling. The purpose of this research will be to analyze the basic mechanism of transmission to the driver.
The final goal of this research should be sharing control that transitions between automatic operation and manual operation with the intention of the driver, but this time, we focused on Haptic, which is the steering reaction force of the SBW system during the transition, and made a series of research plans. Among them, we will report the results of consideration for confirming the feasibility of reflecting the inertial reaction force (RI: Reaction Inertial torque) from the vehicle with respect to the predicted steering in the Haptic, useful findings, and future issues.departmental bulletin pape
Alterations in the Text Reading Thomas Wyatt in the Context of Publishing Tottel’s Miscellany
Full text linkapplication/pdfRichard Tottel published Songs and Sonnets, commonly known as Tottel’s Miscellany, in 1557, in the reign of Mary I. It includes works of some renowned courtly poets in the court of Henry VIII and works written by contemporary poets. Before being printed, courtly poems were usually circulated among closed circles with a limited readership in the form of a manuscript. Editing the first printed anthology of English poetry, presumably targeting a wider audience, Tottel modified the original texts in various ways: one major change was adding titles. This paper mainly looks at the compiled works of Thomas Wyatt, one of the prominent figures in the anthology, and examines the attached titles and other significant alterations. In doing so, it will become clear that those changes were given in accordance with the particular needs of a popular audience and the Marian political context.departmental bulletin pape
A simple magic using a super ball
Full text linkapplication/pdfA simple magic using a super ball and a cylinder was found. We analyzed this mysterious phenomenon by considering conditions for equilibrium. We proposed that a large coefficient of friction of super balls and an elasticity of hands play important roles for this magic.departmental bulletin pape

A study on the use of Career Passport in special activities
Full text linkapplication/pdf新しい学習指導要領が2020年度より小学校から順次実施されおり，高等学校においては2022年度から実施される。この度の改訂では，小・中・高等学校の特別活動において学級活動・ホームルーム活動で児童生徒一人一人のキャリア形成と自己実現を図る取組が重視され，児童生徒の発達段階に応じた体系的な指導が求められている。この手段として，児童生徒の活動を記録・蓄積する教材「キャリア・パスポート」を活用することになった。このことを受けて，小学校から高等学校までの体系的なキャリア教育の充実を図る取組が始まっている。本研究は，「キャリア・パスポート」及びその実施上の課題を整理し特別活動における活用について考察した。departmental bulletin pape
