We developed a high-speed vision robot system that can be applied to various types of products. The developed system consists of a robot with cameras and lights, and a computer for teaching and image processing. In the system many points on any faces of the product can be inspected without stopping with the help of the developed robot path planning and the synchronous method between robot path and image input. Moreover, we developed standard inspection algorithm and unified environment for robot and vision teaching. Therefore the teaching operation can be done without programming. This system is currently in use in our plants so that it can be helpful in keeping high quality of products.

Many kinds of chemical sensors have been developed to detect various air-pollutants. Generally sensor systems are composed of plural chemical sensors and a computer, and the systems can derive kinds of pollutants, densities of the pollutants, and various risks for environments and humans. Regarding the research of sensor systems, there are literatures about a sensor agent, which regards a sensor as an agent, and a utility mobile robot which attaches odor sensors. In these systems, it is necessary that observed results output by the sensors are exactly analyzed with information processing; especially, it is important to recognize the occurrence of events such as outbreaks of odor, however, this kind of recognitions are still not enough and it does not mean that the systems can recognize all the environmental events. In this research, odor sensors are treated and generally odor sensors are designed modeling functions of human nose. Hence, as well as odor sensors, we aim improving the accuracy of environmental recognitions using an odor sensor system attaching an information processing function according to human senses. In addition, we show the usefulness of the proposed system comparing with a conventional technique.

被教示者が教示者の動作を学習するために視覚情報を用いたシステムを利用する際,動作の種類や目的に適した教示動作提示方法を選択することで効率的な学習支援が可能である.本研究では,教示動作提示方法を,被教示者の体と教示者の体との位置関係によって,主観位置条件,3軸一致位置条件,2軸一致位置条件,1軸一致位置条件の4つの位置条件に分類し,それぞれの特徴を調べることを目的とする.それぞれの位置条件の特徴を調べるために,姿勢を模倣する実験と動作を模倣する実験を行った.その結果,主観位置条件は部分的な動作の修正や細かな姿勢の模倣に適しており,3軸一致,2軸一致,1軸一致の位置条件は動作の全体的な模倣に適していることがわかった.

The purpose of this study was to investigate the effect of. "TANDEN"-breathing (which is one of an adminal breathing method is used,by KOBUJYUTSU training) on blood lactate after high intensity running exercise. Thirty healthy basketball players of high school student participated in this study. They were separated to control group and "TANDEN" group and the "TANDEN" group trained TANDEN-breathings for 30 days. The exercise test underwent 3 times, (before beginning training, 15 days and 30 days after training.) Their blood lactate were measured on 0, 10, 20 and 30 minutes after the high intensity running exercise. There were no differences among training periods in control group. In TANDEN group, there were significant differences among training period, (p < 0.05) In comparision with control group,the decreasing rate of blood lactate were significantly grater in TANDEN group, (p < 0.05) These results suggest that to control breathing after high intensity exercise is effective to remove blood lactate which made by high intensity exercise in a short time.

8パズル及び一回り大きくした15パズルについて、探索に基づいた解法がこれまでいくつか研究されている。通常、これらのパズルの探索による解法では、ゴール状態までの手数が少し長くなると容易には解けない。また、効率良い探索を行なうためにヒューリスティック関数を考案することも一般に難しい。そこで、今回は8パズルに対し、探索ではなく問題をいくつかの小問題に分割しそれらの各サブゴールに到達するための整列戦略に従って、状態遷移オペレータを次々に適用することにより高速に問題を解決する手法を提案する。また、いくつか例題に対し代表的な探索方法と比較実験を行なったのでその結果を報告する。

ダマシンゲート構造を有するMetal/High-kゲートスタックとeSiGe S/Dを用いた歪みSiチャネルを組み合わせたMOSFETの試作にはじめて成功した。ゲート電極材料には、nFET用にHfSix、pFET用にTiNを採用した。その結果、Vd=1 V, Ioff=100nA/um, Tinv=1.6nmで、nFET: 1050uA/um、pFET: 710uA/umの特性が(100)基板上で得られた。さらに(110)基板上のpFETのインテグレーションにも成功し、830uA/umの特性が得られた。これらの特性は0.03A/cm^2以下の低ゲートリークの条件下で実現した。

The purpose of this paper is to reexamine the use of "Comprehensive and Multi-dimensional Evaluation" as the basis for University Entrance Examinations. Though the phrase "Comprehensive and Multi-dimensional Evaluation" itself was first articulated in the 1997 report of the Central Council for Education (Chuou Kyoiku Shingikai), the concept itself came into existence immediately after the postwar period. In fact, "comprehensive evaluation" was merely an excuse for avoiding having to add the score of Japanese Scholastic Aptitude Test (Shingaku Tekisei Kensa, used from 1947 to 1954) into the total score of the University Entrance Examination. Moreover, the term "multi-dimensional evaluation" appeared in the outline of the University Entrance Examination (Daigaku Nyugakusha Senbatsu Jisshi Youkou), as it is proposed in the first report of the National Council on Educational Reform (Rinji Kyoiku Shingikai) in 1985. In fact, the report of the Central Council for Education (Chuo Kyoiku Shingikai) in 1971 stated that "Comprehensive and Multi-dimensional Evaluation" was scientifically valid as a basis for University Entrance Examinations. The report is famous as the only report based on evidence, and is generally known as the "1971 Report" (Yonroku Toushin). In the interim report, the Central Council for Education stated that follow-up surveys by the National Institute for Education and the Educational Test Research Institute (Nouryoku Kaihatu Kenkyujyo) had proven that a "Comprehensive and Multi-dimensional Evaluation" could be a valid selection method for predicting a good Grade Point Average after entrance to university. However, the two surveys cited contained simple statistical errors. The first, survey by the National Institute for Education, failed to control for the "Selection Effect." A "Selection Effect" is a "restriction in range problem," caused by cutting off the distribution at the passing grade. As a result, there is a tendency to misunderstand the fact that, in actuality, academic achievement tests on University Entrance Examinations have little relationship with Grade Point Average after entering university. To tell the truth, this problem had been pointed out as early as 1924 by Japanese psychologists who were interested in Entrance Examinations. In the second survey, by the Educational Test Research Institute, the inevitable nature of multiple correlation coefficients was ignored. As the number of independent variable increases one by one, the multiple correlation coefficient necessarily reaches the maximum of 1. In this paper, the follow-up research data from the Educational Test Research Institute is recalculated using a multiple correlation coefficient adjusted for the degrees of freedom. The conclusion is different from that reached by the Central Council for Education. This demonstrates that there is absolutely no scientific ground for the use of "Comprehensive and Multi-dimensional Evaluation." In other words, it is not necessarily correct that putting a lot of effort into University Entrance Examinations and using anything more than academic achievement tests as reference for University Entrance Examination will lead to more students gaining good grades after entering university. If this mismeasure of academic achievement is not properly recognized, the number of university students who cannot achieve even low basic competence level will surely increase.
