Abstract:
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.
Abstract:
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.

Abstract:
A photosensitive paste composition including a conductive particle, an inorganic binder, and an organic vehicle, in which the amount of solids in the organic vehicle is 8 to 12 parts by weight based on 100 parts by weight of the composition and 10 to 20 parts by weight based on 100 parts by weight of the conductive particle. When using the photosensitive paste composition, the thickness shrinkage rate of a dried film upon burning is reduced to less than 40%, and thus an edge-curl phenomenon that an edge portion of an electrode pattern is curled is minimized. Thus, a PDP electrode having an increased withstand voltage and a PDP including the PDP electrode can be provided.
Abstract:
A cathode for an electron tube and a preparing method therefor are provided. In the cathode for an electron tube having a base metal and an electron-emitting material layer, the particle size of the micro structure of the surface of the base metal is controlled to be in the range of 3 to 50 &mgr;m. The cathode for an electron tube has an excellent effect of diffusing intermediate products generated during the operation of the cathode, and is capable of consistently supplying a diffusion path of a reducing agent. Also, the cut off drift rate can be reduced, thereby attaining a long life span characteristic.
