摘要:
The present invention relates to a zipper cord yarn and a reflective zipper wherein the zipper cord yarn containing a reflective yarn is sewn on a zipper by means of lock stitch, thereby enhancing the visibility of the zipper through retroreflective properties of the reflective yarn. The zipper cord yarn includes a core yarn, and a covering yarn made of a reflective yarn to cover the core yarn.

A method of manufacturing a printed circuit board having a bump is disclosed. The method includes preparing a first carrier having a first circuit formed thereon, compressing the first carrier to one surface of an insulation layer such that the first circuit is buried, stacking an etching resist on the first carrier in accordance with where the bump is to be formed and forming the bump by etching the first carrier. In accordance with an embodiment of the present invention, the difference in height between a bump and its adjacent bump in a printed circuit board can be reduced, and thus electrical connection between an electronic component and the printed circuit board can be better implemented.

Disclosed is an antifoaming agent for vinyl chloride resin slurry. The agent of the present invention may prevent generation of Fish eyes and deteriorate in production efficiency caused by slurry foams without inhibiting inherent transparency of vinyl chloride resins, in the process of preparing the vinyl chloride resins by polymerizing a monomer mixture containing vinyl chloride as a main component in a polymerization reactor.

Provided is a ball grid array substrate, a semiconductor chip package, and a method of manufacturing the same. The ball grid array substrate includes an insulating layer having a first surface providing a mounting region for a semiconductor chip, a second surface opposing the first surface, and an opening connecting the second surface with the mounting region of the semiconductor chip, and a circuit pattern buried in the second surface. Since the ball grid array substrate is manufactured by a method of stacking two insulating layers, existing devices can be used, and the ball grid array substrate can be manufactured as an ultra thin plate. In addition, since the circuit pattern is buried in the insulating layer, a high-density circuit pattern can be formed.

An apparatus and method for improving visibility of an image. The apparatus includes: an image input module receiving an image; an illuminance sensing module sensing external illuminance; a visibility compensating module compensating the input image by mapping the input image from a first color gamut to a second color gamut on the basis of the sensed external illuminance; and an image output module outputting the compensated image.
摘要:
A method and apparatus for controlling an operation mode in a mobile terminal provides the mobile terminal to determine whether a predetermined time has elapsed, after a lapse of which it enters a first power-saving mode, and drive a camera module if the predetermined time has elapsed. Meanwhile, the mobile terminal determines whether a predetermined subject is recognized by the camera module, and then delays changing to the first power-saving mode if the predetermined subject is recognized, and enters the first power-saving mode if the predetermined subject is not recognized.
摘要:
Disclosed are a liquid storage container and a clothes dryer having the same. The liquid storage container comprises: a reservoir installed at a clothes dryer, and configured to store liquid therein; a floating member floating on the liquid, and disposed on the reservoir with a rotation angle variable according to level change of the liquid inside the reservoir; and display means configured to display information corresponding to the rotation angle of the floating member. The rotation angle of the floating member may vary according to a remaining amount of the liquid. And, the remaining amount of the liquid may be informed to a user through the display means. Accordingly, the user may easily check the remaining amount of the liquid without checking the inside of the liquid storage container.

Disclosed are biodegradable microspheres, capable of releasing a glucose-regulating peptide in a controlled manner, comprising a biodegradable polymer carrier with the glucose -regulating peptide encapsulated therein, and methods for the preparation thereof. In addition to ensuring high encapsulation efficiency and high stability of the encapsulated drug, the microspheres shows neither an initial burst effect nor incomplete release and allows the zero -order release of drugs over a prolonged period of time, thus improving the therapeutic effect of the drug.
