Abstract:
The present invention discloses a high strength low shrinkage polyester drawn yarn used as industrial yarns and a process or producing the same. The strength low shrinkage polyester drawn yarn has a thermal relaxation stress change ratio of 5 to 100% and a thermal relaxation stress area ratio of 50 to 140% on a thermal relaxation and shrinkage stress curve with a final temperature set to 170° C. The process for producing a high strength low shrinkage polyester drawn yam by a direct spin draw (DSD) process in which a quenching delay region I is mounted, wherein the high strength low shrinkage polyester drawn yarn is produced in such methods that a spinning oil is attached to the yarn being spun with an oiling apparatus 8 mounted at the position 500 to 1,500 mm below from the lower bottom surface of the insulating board 3, the relaxation stress of the yarn is controlled with one or tow tension guides 9 mounted between Godet rollers of a relaxation region III, or both oiling apparatus 8 and tension guides 9 are mounted.
Abstract:
While a user uses one service in a digital multimedia broadcasting receiving terminal, there is implemented a function for suspending the service currently being used and enabling a different service to be used when the different service is provided. A function for enabling a call service to be used during a broadcast service is implemented. A call screen is displayed in a state in which a broadcast service connection is maintained, such that the user can use a new call service without stopping the broadcast service currently being used. In this concurrent service, switching between the call screen and a broadcast screen is possible. This display method can prevent images of the respective services from overlapping with each other and can provide one service without stopping another service.
Abstract:
Disclosed herein is a built-up type box-shaped steel column for filling concrete therein, that can be formed easily and economically in a built-up scheme by using ┐-beams and steel plates, and a method for manufacturing the same that includes bonding a steel plate at the inner surface of a ┐-shapes during a process of making a built-up type box-shaped steel column, thereby having a good resistance against a lateral pressure of concrete filled in the steel column and preventing the bonded portion from being exposed to the outside to provide a better outer appearance. The built-up type box-shaped steel column for filling concrete therein, includes: a ┐-shapes disposed at each of the four corners of a box-shaped steel column to be formed; and a steel plate disposed between the ┐-shapes adjacent to each other for connecting the ┐-shapes with each other.

Abstract:
Provided is an apparatus, method, and medium for allowing a mobile robot to simultaneously perform a cleaning process and a map-creating process. The apparatus includes a feature-map-creating unit creating a feature map for recognizing the position of a mobile robot; a path-map-creating unit creating a path map including a plurality of cells, each having information about whether an obstacle exists and path information, on the basis of information on the pose of the mobile robot that is obtained from the feature map; and a motion-control unit moving the mobile robot on the basis of the information about whether the obstacle exists and the path information.
Abstract:
Disclosed herein are a method for surface-treating a printed circuit board and a printed circuit board including a surface treatment layer. The method includes: plasma-treating a surface of a printed circuit board; treating the plasma-treated substrate with an organic solderability preserve; performing heat treatment on the substrate treated with the organic solderability preserve; printing a solder paste on the substrate subjected to the heat treatment; reflowing the solder paste printed substrate to fix the solder paste; and deflux washing the resulting substrate.According to the present invention, the discoloration problem due to oxidation of copper can be solved by performing heat treatment under predetermined conditions after treatment with an organic solderability preserve. Therefore, the present invention can meet various multi-reflow processes, as compared with products of the related art.
