No full textSexual differences in Sawako Ariyoshi's "Ki River"
No full text有吉佐和子の長編「紀ノ川」には、その終末部分の原型というべき短編「死んだ家」がある。祖母－母－自分の関係を同じくモデルとしながら、父系の家の衰滅を描くに留まった「死んだ家」に対し、物語中の性的差異をいかし、父系の家は衰滅しても、女には女の絆で繋がれた家があることを描いたのが「紀ノ川」であろう。本稿では、女人高野と呼ばれた慈尊院の乳房形と紀ノ川沿いの嫁入りの言い伝えによって呼び込まれる生／死、自然／不自然という二項対立のイメージ、家紋ではない女紋の変更と継承で表明される女の意識／無意識、「真谷家の主」と呼ばれる白蛇で表象される姑－嫁関係、「死んだ家」と同じく終末部分で朗読される『増鏡』の法皇と東宮の関係の祖母と孫娘への置き換えなど、「紀ノ川」に頻出する性的差異のある事象に着目しつつ、有吉が描こうとした女の絆、女の家とはどのようなものかを考察した
Development of Wireless Sensor Network Platform for Educational Use
No full textThis paper describes the architecture and implementation of a wireless sensor network for educational use. The purpose of this development is intended to support students to develop original IoT applications using the wireless sensor network. The system consists of Raspberry Pi as a sensor server and XBee modules, which employ ZigBee as a wireless interface. All the software developed in this study is written in Python and is open to students. Students are allowed to develop their own IoT applications based on their own ideas. This paper first introduces the outline of ZigBee and XBee, then it describes the detail of XBee control by Python and its interface with CGI program. It also reports the experiments of multi-hop communication by XBee modules and the exclusive control, which is needed to keep consistency of XBee control when multiple users try to access the sensor server simultaneously. Basic functions of the sensor network have been confirmed through the experiments
Driving Mechanism of a Travelling Wave Ultrasonic Motor(Travelling Wave on the Stator Surface Subjected to the External Excitation)
No full textA travelling wave ultrasonic motor is an actuator that exploits vibration. Vibration in the ultrasonic range occurs in the stator, which is the oscillator of this motor. Because the vibration amplitude is extremely small, however, experimentation that employs the actual unit is difficult. In the research presented here, the stator of the ultrasonic motor was replaced by an elastic beam of finite length. A theoretical analysis of lateral vibrations of the beam, generated by imposing a forced displacement at the same frequency with a phase difference to both ends of this beam, was conducted. An apparatus was also fabricated with shakers installed on both ends of the beam. Appropriateness of the theoretical analysis was verified through experiments employing this apparatus. Consequently, generation of travelling waves, standing waves, and receding waves reliant upon the phase differences at the two ends became apparent through the theoretical analysis. The experimentation further confirmed undulations similar to the theoretical analysis results
A Study of the Actual Application and Behavior of Passing Places in Wide Pavements for Pedestrians and Bicycle Users
No full textMuch of the pavement in Japan utilizes the same space for pedestrians and bicycle users. Accidents have increased by 4.5 times in the past ten years. The Japanese government has designated 98 areas as Bicycle-Friendly Model Areas. In this study, we try to understand through a survey the relationship between the passing position of pedestrians and bicycle users by improvement of the pavement environment and we observe the passing positions of each. The investigation area is two Bicycle-Friendly Model Areas in Shiga, and the investigation types are the pole separation type, the fence separation type, and the visual separation type. As a result, we consider that the fence separation type is effective build for both pedestrians and bicycle users from the three types. However we consider that the pole separation type may be desirable when we consider the risk of separation structure built continually and the rate of actual application
