In this paper, a component restricting pressure change caused by oil temperature change is proposed. One of the merits of an oil-hydraulic system is to keep the value of oil pressure when pressurized oil is enclosed in a container. However, it is impossible to keep the value when the temperature of the oil is changed. Using a pressure control sub-system to prevent it, the whole system becomes complicated. In addition to it, the energy is consumed when the pressure is adjusted by the quantity of the oil flowing into or out the container. From these view points, it is effective to develop the component which prevents the pressure change according to the oil temperature change without the control of the quantity of the oil. Therefore, in this paper, a component to prevent the pressure change based on the oil temperature change is proposed to make the merit of oil-hydraulic system certain when the temperature of the oil is changed. And, in the cases where the temperature of the oil is increased and where the temperature of the oil is decreased after it is increased, the basic characteristics of the component investigate experimentally.

The aim of this essay is to show that Plato's educational theory of “Politeia” is based on his ontology and epistemology. With regard to “Politeia”, this has been considered by many Platonists of all ages is a treatise on “Justice”. However, I take the position that this is Plato's theory of education. Teleologically it is “Justice” (δικαλιοσυγη), methodologically it is “Education” (παιδεια), but both are joined together in the metaphysical idea of “Good” (η του αγαθsym;ουιδεα).Proceeding from the above mentionned inner structure, I considered and analysed first of all what shape of system and method education takes in the “Ideal State”. For Plato the concrete basis of man's education is his nature (φυσιs). In the long process of education of his Ideal State everyone is chosen according to his virtue (αρετη) and assigned to the various classes of citizens. Thus the custodian who having attained wisdom (σοφια) belongs to the highes class is the philosopher-king. In him philosophy and politics are perfectly one.The establishment of the Ideal State presupposes the formation of the man of the “Polis”, i. e. the citizen, and only by that becomes possible. Consequently, in the Ideal State education has to become a main subject, and in it the education of the custodians takes the central place. The characteristics of their education are : (1) all mathematical sciences are considered important as training the power of seeing things as they are ; (2) philosophy which contemplates the ideas is placed in the uppermost rank. At the base of the curriculum is hidden the big aim of education the “transformation of the soul” (ητεχγητηs περαθsym;ωγηs). From this Plato leads to the comprehension of the “Idea of Good”, and thus aims at man's logos-perfection. In this, it would seem, the foundation of Plato's educational theory consists.

(1)動物モデルでの扁平上皮癌腫瘍組織における放射性医薬品輸送蛋白発現の免疫組織学的染色による検討では、輸送蛋白の細胞膜上発現が顕著に観察され、放射性医薬品の取り込みと汲み出しとの相関が明らかであった。(2)ピンホールコリメータを用いたリンパ節模型のシンチ画像撮像では、臨床を想定した条件下ではピンホール径は5mm以上必要であり、小さな径では計数値の不足による雑音の影響が無視できなかった。また、10mmのリンパ節サイズ模型における放射性医薬品の局在識別は5mmが限界であった。
