A NEW MICROCOMPUTER
An entirely new microcomputer has been developed in our country. The microcomputer is equipped with an arithmetical logical device which carries pre-set programmes. Because of this the microcomputer can perform various logical functions. In other words, it possesses a solving field for various commands. It is comparatively easy to change commands or add new ones.
The arithmetical logical device is known to be adjusted by computers of a higher level. The memory device based on semiconductors keeps information for several days, even with the power supply unplugged. In this case the microcomputer automatically switches over to the microaccumulator.
The new computer is very small in size and weight, resistant to temperature fluctuations, reliable and easy to operate. It does not require special ventilation. It can be used in computer control complexes as an information-processing unit and also as a built-in computer in various analysing and display devices. It receives data, calculates the optimum conditions and supplies signals for the control of technological processes. For example, in pressure-die casting the microcomputer receives information about the temperature in the fu
ace, the speed of the liquid metal movements, location of the various devices, etc. The computer processes the data and controls the casting, i. e. keeps the temperature and the pressure within required limits, and commands the beginning of the casting operation. The programme is written by technicians, and the operator inserts the required data.
The field of application of the new computer appears to be vast. It can analyse various substances in oil, gas, chemical and food industries, as well as soil and plants. It can also be used for processing information about conditions in the environment, for control of conveyors and other equipment.
