In the turning process, the cutting-off is one of the difficult works. There are some unsteady phenomenon as built-up edge and chatter vibration because the cutting velocity is changed during cutting-off from the outside of the work to the center. So the skilled machinists of cutting-off control the depth of cut according as the cutting force, the cutting image and the cutting sound information. In this report, the relationships between cutting force and depth of cut are discussed both the hand-operated cutting and the cutting of auto-feed of depth.

This paper is a proposal of a new SIS making process. One of a proposal is a method that I easily can wire to a small junction. Another is to be a few and be able do for damage by etching to small junction. This making process is the following method. At first, it make wiring portion and large junction structure. As being next, the portion to have been shaved with etching process fill up to become a same height as another portion. Last process, it make for the very small SIS junction that was connected with for 2 series. By this method, for a flat portion, a making of a SIS junction by an electronic exposure gets possible. And, an influence of etching against SIS junction is once it. Damage by etching gets a few if it is in comparison to a former making process. Further, it thinks that this making process can apply it for a bolometer mixer device making also.

Sandbox model is generally used in a model experiment simulated shear deformation in case of fault development in Quaternary deposit. This study was performed by using aluminum rods model in order to exclude the influence of possible difference between actual and observed phenomena due to wall friction in sandbox model covered by box. The bedrock stress after shear bands is formed, is clarified by aluminum rods model simulated reverse fault displacement.

In the post-buckling analysis of axially compressed thin-walled cylindrical shells, we can use two kinds of strain-displacement relation, i.e. Donnell type and Flugge type. Former is relatively simple, but is not so correct (due to shallow assumption) when a shell becomes long. In this study, the Flugge type is employed and more accurate euilibrium paths in the post-buckling region are traced numerically. In order to estimate the snapping or bifurcated paths, the energetic evaluation is also applied.

In this paper, we prove Ajima's theorem related to "kan-en", or the status of several circles contacting each other like a ring, by using the method of analytic geometry. The theorem can be applied to solve many problems of the "kan-en" appeared in the "sangaku" that have existed in Chiba Prefecture, and several examples of them are shown in the following.

Communication skills have been taught in classrooms both in junior and senior high schools since the subjects Oral Communication (A)(B)(C) appeared in the 1989 Course of Study. Among the skills communication strategies are the focus of the teacher's attention inside the classrooms as well as outside classroom activities. The author of this paper has been trying to investigate how communication strategies are taken up in the textbooks which have been used for teaching English language as a foreign language in Japan. He has had three kinds of research from the points of communication strategy: the junior high school English textbooks, the screening tests for senior high schools , and senior high school English textbooks. In this paper the previous studies in communication strategy, comparing with learning strategy, and teachability of the strategies. The result of the textbooks and screening tests investigations will be published in the following editions of this bulltin.

30 years have passed since 1968, the year of which was the turning point in the Vietnam War. The My Lai/Son My Massacre, the most notorious atrocity of the Vietnam War, was executed in the year. Both the United States and Vietnam have changed since than in many respects. But the massacre has been "the severest wound" for the Americans. This paper deals with deep consideration of the My Lai Massacre and its aftereffects on the Americans, examining the political and social changes in recent years. America and Vietnam established full diplomatic relations in 1995, and many American citizens have visited Vietnam, and they are trying to put the past behind them. It can be said that the new era began in the mid 1990s. But the analysis of the documentary film Four Hours in My Lai makes it clear that both Americans and Vietnamese, who concerned the incident, are living their lives full of sorrow, agony, and regret, even though some of the Americans say that they just obeyed the order. On the other hand, there are many people and organizations that make efforts to make peace between the two countries by raising subscriptions and so on. They keep devoting themselves to healing the wounds. What has been examined in this paper finds that it will take more time for Americans to be relieved from the burden of the My Lai Massacre.

The vocabulary in authorized textbooks of English by the Ministry of Education has long been criticized as too receptive compared with those of other countries. It is said to be of little use when students try to express themselves or meet their dairy needs in English. The author has found that the vocabulary in the authorized textbooks of English I and II is not as helpful to his students as expected in real situations. He guesses the neglect of "action verbs of daily lives," verbs concerning our behaviors and activities in daily lives,in authorized textbooks might be one of the causes of their uselessness in real situations.

We can resolve the arrow's paradox of Zeno by using the concept of monad of Nonstandard Analysis. But, this mathematical solution leaves some contradictions unsolved in the concept of monad itself. If we want to solve these contradictions, we must know the reason why the contradictions of the middle occur.
