He learned in detail about the performance of the optical measuring instruments being produced by the factory.

It further improved the performance of the instruments than last year and ensured their safety, he said, adding that in order to make the instruments produced at the factory prove effective in reality, it is necessary to further raise their precision.

The inquiry into the performance of the instruments today proved that it is quite possible to succeed if endeavors are made, based on scientific researches and technological updating, he noted.

He looked round the assembling shop to acquaint himself with production there and quality of products.

He said that the optical measuring instruments being produced at the factory require high technology, stressing that in order to keep the production going at a high rate and improve their quality it is necessary to give full play to the mental power of the producers, intensify scientific researches and steadily raise the level of technical skills of the workers.

He underlined the need to focus efforts on the independent technological development capable of surpassing the world level, put the production processes on a modern and automatic basis and wage a more dynamic drive to raise the rate of locally available equipment and materials.

He also underscored the need to raise high demands to the units producing items of cooperative production and successfully conduct cooperative operations.

He watched CNC-based machines at work in the assembling shop to learn about the operation of the equipment.

He set forth tasks which would serve as guidelines for the management and operation of the factory and production.

He had a photo session with the workers of the factory, expressing expectation and belief that they would boost the production of quality and modern glass products and optical instruments by conducting a widespread mass technological innovation movement, true to the WPK's idea of pushing back the frontiers of the latest science and technology.

He was accompanied by Choe Ryong Hae, Choe Hwi, Pak Thae Song, Hong Yong Chil and Ri Man Gon, chief secretary of the North Phyongan Provincial Committee of the WPK.
