    1. In early days of automobile manufacture, in Japan, U.S.A. and England, high alloy steels were used to make automobile parts. But afterwards, developments of design of automobile parts, to-gether with more accurate manufacture and finer surface finish, have greatly improved the service life of automobile parts.
    This resulted in very much less accent on the importance of basic alloy composition, so that the available lower cost, lower alloy grades could, with the highly developed heat-treating control and investigation on the hardenability of steels, be used interchangeably for automotive applications.
    2. The author investigated and compared the grades of steels made in Japan, U.S.A. and England, concerning not only the kind of steels but also a quantity of incidental alloying elements, non-metallic inclusions and the grain size in steel.
    The result of comparison showed that, grade of automotive steels made in U.S.A was the best of all and steels made in Japan was, to a great regret, the poorest of all.

    The laborers in the salt fields are working under the specific environments, influenced by the particular climate and weather conditions there. A great number of them pursue the agriculture as a side job, and under the circumstances there has been brought up a specific labor consciousness like it in peasantry. I have enquired into the afore-mentioned points from the various angles as follows :
    1. General labor feelings ;
    2. Their consciousness towards the managements ;
    3. Their companionship ;
    4. The consciousness of their promotion and wage increase ;
    5. The security feelings in their positions ;
    6. The consciousness of their own works ;
    7. The changes in their own jobs ;
    8. Their consciousness of the labor law ;
    9. Their consciousness of the labor union ;
    10. Their upholding of the political parties.
    Item 1 : An overwhelming majority of the laborers feel that their works are realy very hard work.
    Item 2 : While we find a great number of the workers that support their employers with the warmth of parental affection, there are also no small number of workers who maintain rather non-committal attitude towards their employers.
    Item 3 : The laborers works on fairly good terms, but no particular and special relationships exist among workers themselves.
    Item 4 : We find more of those who feel stabilized in their works than those who are not so considered, but the difference between the above two is not so much noticeable.
    Item 5 : The majority of them are dissatisfied with the present promotion and wage increase.
    Item 6 : Many of them are willing to change their jobs for better ones should there be any good chance there of, and there come next those who would like to stay in their own present positions. The difference between the two of the above workers is not very much ; as for their own children, however, almost all of them are disposed never again to let their youngsters follow the same job as their own.
    Item 7 : The number of the changes in their jobs is comparatively small and those who have made only one change there of predominate.
    Item 8 : They take almost no interest in that sort of the labor legistrations.
    Item 9 : The majority of them rely on the labor union, on which they place their positive hopes.
    Item 10 : A very great number of them support the Socialist Party.
    The salt field laborers have such labor consciousness as above enumerated, and in our study there of we should probe deeply into the matter by comparing it with the general labor consciousness. The general points on the problems for labor consciousness can be devided into : (1) the general feelings for labor, (2) their consciousness towards the managements and (3) the mutual consciousness of the laborers.
    The (1) indicates the laborers' feeling for pleasure and pains and their labor sentiments. No. 2 comprises the parental management consciousness, the anti-management consciousness and other kind of consciousness. No. 3 denotes the mutual perental feelings, antagonistic sentiments and other general feelings.
    These laborers' consciousness is regulated according to the existense of the laborers and consequently it must first be brought light on the subject of the existence of the laborers, and then look further into the questions of their consciousness.
    With respect to these items of the problem, such industial sociologists as E. T. Hiller, L. Warner, A. M. Rose, D. C. Miller, U. S. A., and Kunio Odaka, Shizuo Matsushima, Japan, are investigating the matter from their respective point of view, and as a result of my tracing the valuable researches made by those authorities on the subject concerned, I have now been able to grasp the aforementioned itemes of the question.
    Under such circumstances, I have tried to reexamine and scrutinize many of those valuable and interesting questions in comparison with labor consciousness in this brief article.

      The viscosity change in solidifying Sn-Pb and Al-Si alloys was investigated using a torsional transduccr forced to oscillate at a resonance frequency. Since the amplitude of vibration was only 1μ and the skin depth was less than a few millimeter in this viscometer, it has only a very small stirring effect on the melt. Therefore, the features of solidification of melts were reflected well in the results of viscosity measurements with this apparatus.
      There was a rapid increase in viscosity at the beginning of solidification in the supercooled melt. In the eutectic alloy, the beginning of viscosity increase at the eutectic temperature was delayed, but once the change began the viscosity increased sharply. Viscosity increase was more rapid in alloys with wide freezing range than in those with narrow freezing range. Viscosity increase was more rapid in alloys which primary phases crystallize dendritically than in alloys which those crystallizes planarly. Viscosity increase was more rapid in alloys which crystallize many small primary solids than in alloys which crystallize only a few large solids.

    本稿の目的は,首都圏近郊の東海道線沿線における大規模工場用地の利用変化と存続工場における研究開発機能の新展開を分析することである.首都圏に古くから立地してきた大規模工場は,特に都心に近接している場合,その多くがすでに閉鎖し,オフィスビルやマンション,商業施設に変化していた.しかしながら,マザー工場として生産機能を維持することで,あるいはまた研究開発機能を強化することで,存続している拠点も存在している.特に2000年代以降の研究開発機能の変化としては,1)製造機能と研究開発機能との近接性を重視した研究開発機能の強化,2)顧客志向の研究開発拠点の増設,3)シナジー効果の創出を目的とした集約型研究開発拠点の新設といった点があげられる.
