On display there by way of products, graphic boards and programs were more than 1 500 sci-tech achievements of 700 odd kinds, made by institutes under the State Academy of Sciences in the last ten years.

Most of the exhibits are ultramodern products of great importance in promoting the economic development of the country.

Middle-frequency induction furnace, developed by the Integrated Circuit Institute, is helpful to increasing the steel production, with 40 percent less electricity and 35 percent less fireproof materials than low-frequency induction furnace. This invention has been introduced to more than 50 industrial establishments, and it won a high appreciation from among experts and producers for its contribution to making equipment small, light and safe.

The Industrial Information Research Center developed a computer control system for 100-tonne UHP electric arc furnace, which is now proving effective at the Hwanghae Iron and Steel Complex. The system sharply reduces the consumption of electricity as well as electrodes.

Heat-sensing unit, invented by the Ferrous Metal Research Institute, is conducive to the modernization of production processes at different sectors of metal, chemical, machine-building and light industries.

The Mechanical Engineering Institute presented more than 100 research achievements of 20 odd kinds, including oil-pressure devices and elements, medical and foodstuff apparatuses and metallic material processing equipment.

There were also penal discussions on sci-tech achievements in bionics, fishery and chemical, light and other industries. Presented to the discussions were data on 200 odd achievements that have contributed to the technological updating of the national economy, according to Kim Jun Nam, department director of the State Academy of Sciences.
