Answer»
- Actuators & Amplifiers with electrical auxiliary energy.
- As the systems in the devices such as watches and cameras are very small and complicated, there is a need of an amplification.
- It cannot be done by PURE mechanical designs.
- Therefore, both the amplifiers and actuators with electrical auxiliary energy are used for considerable amplification in the devices like watches, cameras, electrical typewriters, etc.
- The microcomputers which are in connection with DECENTRALIZED electrical drives are introduced for the result of a considerable amplification in the MECHANICS such as watches, automatic GEARS, etc.
