摘要:
The present invention relates to a method of manufacturing a built-in type upper/lower electrode multi-layer part including alternately laminating a first ceramic sheet having a first internal electrode pattern formed thereon and a second ceramic sheet having a second internal electrode pattern formed thereon so as to form a first multi-layer sheet product; forming first and second via holes on the first multi-layer sheet product, the first and second via holes respectively connecting the first and second internal electrode patterns; respectively joining third and fourth ceramic sheets having no internal electrode pattern on the upper and lower portions of the first multi-layer sheet product so as to form a second multi-layer sheet product, the third and fourth ceramic sheets having third and fourth via holes formed to correspond to the first and second via holes; and filling a conductive paste in the first to fourth via holes.

The present invention provides an elastic permeable pavement comprising waste-polyurethane chips for use on new roads and a paving method using the same. This pavement uses a binder specially developed to secure the binding between an upper polyurethane chip layer and a lower permeable concrete layer as well as the binding among the waste-polyurethane chips, resulting in excellent strength and durability, and uses recycled polyurethane chips to provide elasticity and permeability suitable for sports activities, walking, outdoor exercises and the like.

An apparatus and method for storing and displaying broadcasting caption are provided. Caption information extracted from broadcasting signal and video signal are separately managed. The caption information is extracted from broadcasting signals of a real-time broadcasting or reserved program and is decoded. The decoded caption information is created in a file format and stored in a storage medium. The stored caption file is replayed and displayed. The apparatus provides a function of storing a reservation of caption information, a function of selecting a storage medium, and a useful browsing and managing function for caption file. Accordingly, the caption information can be stored, searched, added, deleted, and moved between storage media.

Disclosed herein is a prefabricated road median wall which is provided along a median line of a road to divide the road into two sections according to the direction of vehicles traveling on the road. The prefabricated road median wall includes a plurality of unit blocks manufactured by mixing rubber powder with a fire retardant material at a predetermined ratio and conducting a compression molding process. The unit blocks are stacked sequentially, with a plurality of support holes vertically formed through each of the plurality of unit blocks, so that the support holes of the unit blocks communicate with each other. The prefabricated road median wall further includes a locking means to couple the stacked unit blocks together, thus forming a median wall body; and a plurality of anchor posts. Each anchor post is embedded at a lower part thereof in the ground while a remaining part of the anchor post is exposed to the outside, so that the exposed part of the anchor post is inserted into each of the plurality of support holes of the median wall body, thus supporting the median wall body on the road.
