The finding that N,N'-diarylmethylenearylmethanediamine (1) condenses with various kinds of compounds containing an active hydrogen in the presence of ammonium acetate at mild conditions has led to the work extending the synthetic applications of the double Schiff base 1. As the results of the research on the reactions of 1 with various reactants, the many novel compounds shown in the text have been heretofore synthesized, and the pathways for their formations are estimated.

An earthworm moves in the ground, underground and a narrow crevice using many lots of segments. This movement is called peristalsis, and differs from movement of other animals. And this movement is very simple operation compared with movement of other animals. It is thought that a peristalsis is useful in the calamity spot. However, an author does not know the reference seen about the peristalsis. In case equipment will be developed from now on, it is thought that the elucidation of the move mechanism of an earthworm that used the peristalsis is very important. In this research, a camera and equipment are used and it aims at solving the detailed movement mechanism of an earthworm.

It is few that phase information is handled as a research on tone color. Because it has been thought that the phase is unrelated to the tone color. However, the result that the human can detect the phase difference is also reported, when the phase difference between each component sound of complex tone was changed. In one of the auditory sense psychological phenomenon, by the change of the harmonic composition the tone color changes, and it is not change sound pitch. This phenomenon is called "Phenomenon of the missing fundamental (MF)". As we paid attention to this phenomenon in this research, we confirmed the mechanism and examined the influence of the phase change between the component sounds to the perception of MF. As the result, it has been found that the changes of the pitch and the tone color take place in the perception by giving the phase difference. So, we concluded that not only each frequency component but also phase is largely related to a tone color.

男女識別は大型商業施設やアミューズメント施設等の来客統計をとるためなどに必要である.従来の男女識別方は,服装や歩き方,足圧,髪型および声など人物の外見を利用した方法である.しかしこれらの特徴は人間の意思により恣意的に変えることのできる特徴である.本手法は男女の特徴の相違を赤外線画像の顔または手の熱分布により行う生体的特徴を用いた新しい概念に基づく男女識別方である.したがって,本手法は従来手法にない強固な男女識別を実現可能な法である.

Toward development of useful environmental sensing system by using supersonic pulse echo technique, we construct a simple system to visualize the positions of objects in near-field. In this bulletin, after the outline of principles of supersonic pulse echo technique and visual localization of objects is given, we mention about constructed 2D-visualization system and result of experiments by the system, and the feature and effectiveness of proposed method and system are made clear.

ヘミングウェーは形容詞をできるだけ省略した平易で単純な文を書くことで知られている。この「省形容詞」の文体は、修飾辞による曖味さを極力なくすことによって、鋭い描写をすることに成功している。本研究においては、まず、ヘミングウェーの「省形容詞」の文体がどのように出来上がったかを彼の履歴から探り、次に、彼の短篇である『キリマンジャ口の雪』を例に、「省形容詞」の文体の具体例を見る。この点は客観性のある文体が要求される科学技術論文にも取り入れることが可能である。
