High Aspiration
Kim
Pyong Ho, 49, is a section chief at the Mechanical Engineering
Institute of the State Academy of Sciences. He is concerned about what
he will do rather than what he has done. So he always values the time.
A diamond crown, which can make a great development in the geological prospecting field, is one of his achievements.
It
was 28 years ago when he started his scientific research at the State
Academy of Sciences after graduating from the mechanical engineering
faculty at Hamhung University of Chemical Engineering.
In
those days he developed a diamond saw, an electrolytic diamond grinder
and other things. Then he took upon himself the task of developing a
diamond crown badly needed for geological prospecting.
But
he was faced with various difficulties because the research demanded a
broad knowledge of several scientific branches—metallic materials,
mechanical engineering, soldering and drilling.
He
devoted all his knowledge and energy to solving the scientific and
technological problems arising in making the crown, going down to the
major mines in Komdok and Musan areas.
Boldly
deviating from the established ideas and knowledge, he conceived a
novel idea of making the crown at a lower temperature than the existing
method, and succeeded in his research after repeated experiments.
Besides,
he established a tooth frame structure and the boring process
technology suitable for the properties of various rocks, thus improving
the performance of boring tools and facilities. A production base for
them was built.
The
rate of the crown’s diamond slip in performance is very low and its
edges become sharper of their own accord. It was introduced in several
geological prospecting teams, coal and other mines, proving economic
effectiveness.
Without
satisfaction with his successes he is continuously pursuing his
scientific research, regarding it as his task to solve scientific and
technological problems arising in the building of a thriving country,
however difficult they may be.
Much is expected of him.
