The evolution of the technological subject of manufacturing

I look back on how the technological subject of the manufacturing evolved. 　The tool has a prime mover department in one end of the same individual, and there is a work parts in another end. In the both ends of the same individual, the function separates. When the power is necessary, a handle is put, and structure to roll, structure to fly are devised, and a wheel and a bow and arrow are made, and a complex tool is born. 　The first power to use a tool is the person’s power and the power of the livestock, when the bigger power is necessary, a windmill or a water mill is used. 　When a windmill or a waterwheel is used for the prime mover department, it separate for a work part（a quern）and a gear enters as a driving mechanism between those. 　The work machine is comprised of prime mover department, driving mechanism and a working department. In the control system of the machine, the handling of the computer spreads, but the subject existing technological subject of manufacturing is the times of a machine and the machine system. The automation of the machine is being done by introducing electronics and a computer to the control unit in mainly the driving mechanismdepartmental bulletin pape

Relation between the technology and science.（2）

Until the end of the Medieval times, there were no connection between technology and science. But, in the 12th century, the university began to be established in Europe. 　In the early modern times, industry spreads, and increase of the power output and the enlargement of the tool and the device begin. Scientific research began to be organized. The experiment and observation in the scientific research became important. Thus, the science approaches in the technology. 　For the industrial revolution period, production capacity began to increase, and Science developed rapidly. The scientific research of the technological problem in the field of industry is carried out. Science considerably approach in the technology. 　The invention of the mercury pump and the manufacture of the vacuum tubes led to the discovery of X-rays and the electron beam, and the opening of the 20th century technology and science comes. 　The progress of technology provided the conditions and subject necessary for scientific research. And the relations that the result of the scientific research is applied to the technological problem are established. The first framework of modern science was formed in this timedepartmental bulletin pape

The concept of the technology

In the argument about the concept of the technology, many people were arguing it about the production technology. The production technology consists of the technologies that material means used in the process of production has. However, the tool and machinery that use in everyday life have each technology. Therefore, we must argue about the product technology consisting of the technologies that all tools and machines have. I give the concept of the technology about the product technologydepartmental bulletin pape

『深い河』論

神（たとえば「玉ねぎ」といってしまっていいという）とは、単なる存在ではなく、機能を通して知る存在である。機能は神と人間の共生関係において作用する。それは奇跡的で超人的な力ではなく、人知れずとも哀しみを背負う愛のことなのではないか。作品の重要な場所であるガンジス河は母なる神として、生きる者を生かしめ死した者の意志を表出して生者と死者を対話せしめる、死と永遠、転生の深い河なのである。『深い河』において、わが国の固有文化への深化、親鸞の要人正機説へのそれをみる。神の機能哀しみを背負う愛母なる神としてのガンジス河固有文化への深
