This report states three full accounts of what was perceived during the science class. First, the attractiveness of the subject is to be brought about only when teachers are fully engaged. Second, the children's ability to enlighten one another activates their potential and motivation spontaneously. Third, the student's engagement becomes independent when the feeling of accomplishment is individually experienced.

「彼はかなり熱心だった。」という形容詞文に似た表現として「彼はかなりの熱心さだった。」という名詞文がある。本稿は後者のように形容詞の語幹に接尾辞「」が後接した派生名詞を述語とする文の性質を、形容詞文と比較しつつ考察した。「〜」は抽象的な程度概念であるため単独では述定機能を持たず、性状規定文の述語であるためには連体部を必須とする。述語としての「〜」には性状の程度を中立的に述定するものと、評価的に述定するものがある。評価的に述定する機能は「〜」と形容詞が共通に持つ機能であるが、「〜」による述定には何らかの文脈的な前提が必要であり、形容詞文の評価性が形容詞によって表わされる性状の「存在」自体に向けられているのに対し、「〜」を述語とする文の評価性は連体部に示される性状の「あり様」に向けられているという違いがある。連体部と「〜」との意味関係は多様で、連体部は「〜」を述語とする文に豊かな表現力を与えている。

It has been reported that mechanical properties are improved by applying “Strain Tempering (KRK)” process to steel wires containing 0.6∼0.9% C. In this paper the effect of carbon content of steel wires on the mechanical properties in this process has been investigated. Results obtained are as follows: (1) In the case of low carbon steel wires, tensile strength, yield strength and hardness are also improved by this process. These improvements in strength and ductility are expected by adopting suitable conditions of this process as in the case of high carbon steel wires (2) The strength increases with carbon content and reduction are increased, but the maximum strengthening is determined by the relation of carbon content, reduction and treating temperature.

It has been reported in the previous papers that the mechanical properties of metals are improved by “KRK” process which is applied in combination with heating and mechanical force for short periods of time such as a few minutes or shorter. The present paper deals with the effects of “KRK” process on the changes of anisotropy of 2.6% silicon-iron alloy strip. The anisotropy was quantitatively determined by means of torque magnetometer. The results obtained are as follows : The magnetic characteristics of silicon-iron alloy are effectively improved by applying this treatment to the treated strip. That is, the larger torque value is obtained under the conditions in which the tension over the elastic limit at that temperature is applied at a temperature between its recrystallization temperature and 1050° for 5 sec∼15 min. In the case in which strain tempering is applied after the skin pass of few percent cold reduction, this treatment is most effective in magnetic anisotropy. The rotation of crystalline orientation to the direction of magnetization is considered to be accelerated by this treatment.

The cause leading to the improvement of properties in specimens of alloys and solid solutions subjected to the pretreatment of strain-tempering was studied, using samples of heat-treated 0.4% and 0.8% C-steel, and in correlation with it, the removal of the fibre structure and the relation between the fibre structure and the microscopic structure were also investigated. The results obtained were as follows: (1) Cold-rolled specimens show heterogenous microscopic structures in them accompanying fibre structure, causing defects in the specimens. (2) By strain-tempering under appropriate conditions, such a fibre structure can be removed and the microscopic structure of the specimen homogenized. (3) The effect of strain-tempering in removing the fibre structure seems to cause improvement of the mechanical and the physical properties of the specimens when heat-treated thereafter, over those subjected to heat-treatment alone. (4) Our discovery of such effects of strain-tempering has led us to devise a new method of heat-treatment.

The effect of KRK treatment on the precipitation in Corson alloy has been studied by measuring their strength and the following results have been obtained. KRK treatment at high temperature which the precipitation occurs, accelerates the precipitation in ordinary cold-drawn alloy. KRK treatment at such a temperature as that of low-temperature annealing increases the strength of ordinary cold-drawn alloy and so a higher strength is obtained by applying this treatment for each reduction of cold drawing. This low temperature KRK treatment does not accelerate the precipitation but the precipitation is accelerated by high temperature KRK treatment.
