We propose here to define technology system as a set of communications characterized by able/ unable binary code. Technology theory that emphasizes communications is very different from the conventional ones attaching importance to engineers. We survey here for what kind of change the conventional technology theory is pressed.
According to the theory of technology system proposed here, the theme of this technology theory could be classified as the following.
1. Reproductive process of technological communications
2. Boundary problem of ability
3. Fluctuation of ability
4. Uncertainty of technological communications
5. Morality of technological communications
Such a theme cannot be treated only within technology system. It is necessary to treat problems in relation with other functional systems and environment.
In our discussion, we regard mechanical device as a kind of technological communication. Mechani- cal device is also objects of exchange in economical system. This duality of mechanical device produces indirect interaction between technology system and economic system. This kind of duality will cause also the interaction between technology system and other functional systems.
