摘要:
The present invention provides a cold cathode electron source and a method for manufacturing the cold cathode electron source. The cold cathode electron source includes a substrate on which are deposited a catalyst metal layer, an insulation layer, and a gate metal layer; a cavity section formed through the catalyst metal layer, the insulation layer, and the gate metal layer; and an emitter realized through a plurality of carbon nanotubes, which are grown from walls of the catalyst metal layer exposed in the cavity section and which have long axes parallel to the substrate. The method includes depositing a catalyst metal layer, an insulation layer, and a gate metal layer on a substrate; forming a cavity section by removing a portion of the gate metal layer, the insulation layer, and the catalyst metal layer using a photolithography process; and forming an emitter by mounting the substrate on a chemical vapor deposition reactor and growing carbon nanotubes in a low temperature atmosphere of 500˜800 degrees Celsius (° C.).

A photosensitive paste composition is provided. The photosensitive paste composition contains conductive powder, an inorganic binder, and an organic vehicle, wherein, assuming that 10% by weight of the particles consisting the conductive powder have a diameter less than D10 and 90% by weight of the particles have a diameter greater than D90, a difference between D10 and D90 is about 2.0 μm or less. The photosensitive paste composition solves problems arising with use of conductive powder having a broad particle diameter distribution and satisfy requirements for an electrode's main characteristics, such as resistance, the anti-sanding property of terminal portions, and withstanding voltage characteristic. In addition, a PDP electrode using the photosensitive paste composition and a PDP including the PDP electrode can be manufactured.

摘要:
A photosensitive paste composition for forming a black layer on top of plasma display panel (PDP) barrier ribs includes black pigment nanoparticles for contrast enhancement and a cyclic acid anhydride for fundamentally preventing the gelation of the paste composition. The photosensitive paste composition prevents electrical or optical crosstalk between adjacent discharge cells to achieve better contrast. The fundamental prevention of the gelation of the paste composition permits the paste composition to have good storage stability.

Disclosed herein is a continuously variable valve lift system for an engine which is able to variably adjust valve lift and opening duration of intake and exhaust valves operated by the rotation of a cam shaft. The continuously variable valve lift system of the present invention has a compact structure, so that space required for the system in a cylinder head is reduced. Furthermore, the continuously variable valve lift system is provided at a position level with or below a position at which the cam shaft is installed, thus reducing the overall height of the cylinder head, thereby reducing the volume of the engine.

An oxide cathode for an electron tube and a method for manufacturing the oxide cathode are provided. In the oxide cathode including a sleeve for a heater, a metal substrate formed on the top of the sleeve, and an electron emission material layer coated on the metal substrate, the electron emission material layer is formed by coating a carbonate paste containing an alkaline earth metal carbonate, an organic blowing agent, and a vehicle on the metal substrate by screen printing, and thermally treating the coated carbonate paste. Picture quality degradation due to a Moire phenomenon is reduced by coating the carbonate paste by screen printing to provide an even cathode surface, and degradation of the cathode by Joule heat is reduced, thereby improving electron emission and lifespan characteristics of the cathode.
