摘要:
A wire tensioner includes a plurality of rods that apply a tensile force to a plurality of wires. A fluid pressure providing means applies fluid pressure to the plurality of rods to apply the tensile force to the plurality of wires. A fluid control means is connected to the fluid providing means and to the plurality of rods to separately control a fluid pressure applied to each of the plurality of rods.

摘要:
Disclosed is a method for providing photochemical activity by coating a nano-layer of metallic oxide with nano-sized micropores on the particles or film of titanium dioxide (TiO2). The method for coating the nano-layer of porous oxides with hyperfine nano-sized pores on titanium dioxide (TiO2), comprising producing the solution containing metallic salts, providing the solution of metallic salts with TiO2 powder, hydrating the metallic salts and coating the hydrates on the TiO2 powder surface, and forming oxides from the hydrates coated on the TiO2 powder surface. The formed porous oxide coating layer increases the absorption capacity of water or dye molecules by increasing the specific surface area of titanium dioxide (TiO2) particles, thereby improving a photocatalyst characteristic or dye-sensitized fuel cell characteristic of TiO2.

A tension dispersion type complex anchor device includes an internal fixing body having a tension member which is placed through a free length section to apply a tension force and a fixing block to which a wedge assembly for grasping a distal end of the tension member is mounted; a connection medium unit for mounting the internal fixing body to one end thereof; a grip sleeve coupled to the other end of the connection medium unit; and a permanent anchor fixed by being fitted into the grip sleeve to provide an allowable anchoring force through a bonded length section.
摘要:
There is provided a conductive paste for an internal electrode of a multilayer ceramic electronic component and a multilayer ceramic electronic component using the same. One or more nitride powders containing a nitride selected from the group consisting of silicon nitride, boron nitride, aluminum nitride, a vanadium nitride are added to the conductive paste for an internal electrode to increase a shrinkage initiation temperature of the internal electrodes. Accordingly, the reliability of the multilayer ceramic electronic component can be improved by using the conductive paste for an internal electrode.
摘要:
A wire tensioner includes one or more rods configured to separately support one or more wires withdrawn from a structure and introduce a tensile force to be imparted to the wires; a fluid pressure provider configured to provide fluid pressure to the plurality of rods in order to allow the rods to exhibit the tensile force, and a fluid controller connected at one side thereof to each of the rods and connected at the other side thereof to the fluid pressure provider, and configured to selectively interrupt fluid pressure provided to the plurality of rods to control the operation of the respective rods separately.
