摘要:
A cathode for an electron tube includes a layer of a electron emitting substance containing alkaline earth metal oxides containing 0.01--20.0 wt % of both a lanthanum compound and a magnesium compound or a lanthanum-magnesium compound disposed on a base metal including nickel as a major component and tungsten as a minor component. The tungsten prevents embrittlement and ensures a continuing supply of fill barium in the electron-emitting substance. The cathode enjoys full interchangeability with the conventional oxide cathode and a 15-30% longer life span.

Disclosed is a filter needle in which a filter structure is embedded in the inner space of a fixing member of a syringe needle. The filter structure has an inlet and an outlet, each of which functions as a check valve, and an inlet path and an outlet path provided with a filter, wherein the inlet path and the outlet path are formed at the rear end of the filter structure. Thus, when a medicament liquid flows out from the ampoule and injected into a patient, foreign substances, such as powder generated during the opening of an ampoule, which otherwise might be introduced into the main body of a syringe and injected into a patient, are filtered by a filter. The filter needle enables the medicament liquid to be injected into the patient without exchanging the syringe. The filter needle o is integrally formed of medical silicone to enable easy assembly and safety during use.

A shock absorber adapted for use in attenuation of vibration for prevention of sudden increase or decrease of attenuating force of plate-like open/close valve to thereby improve a rideability of a vehicle, the shock absorber disposed with a piston having a cylindrically closed housing filled with fluid where an attenuating force is generated by a fluid resistance caused by the fluid moving through orifices, the shock absorber comprising: a valve formed to horizontally move on upper/bottom surfaces of the piston to thereby open and close the orifices; a guide unit disposed between the valve and the piston to enable the piston to horizontally move and to prevent the piston from breaking away to the other direction; and an actuating unit for horizontally changing a force applied to the fluid to move the valve when the piston is moved toward an expanding direction.

An improved packet switching apparatus with multichannel and multi-cast switching functions and a packet switching system using the same which are capable of more simplifying the routing of an internal routing during the integration of the switching apparatus by using a simpler 2.times.2 switch device for a concentration network in order to provide a routing network and a recirculation path and by using a pattern connection characteristic consisting of a column and row. The apparatus includes an output group address generator for providing an address information of an output port grouped, a routing unit for receiving a cell which is recirculated through a recirculation path and a newly inputted cell, assigning an output link with respect to the recirculated cell when an output port-dependent address inputted from the output group address generator and a destination address set in a routing tag of a cell inputted by the port are identical, and outputting the cells which was not assigned of the output link through a plurality of bypass links, a recirculation path setting unit for selecting a cell as many as the number of circulation paths among cells outputted from the routing unit through the plurality of the bypass links and for outputting the cells through the recirculation link, and a synchronization unit for receiving a cell which is recirculated from the recirculation path setting unit through the recirculation link.

An anti-roll system for vehicles includes first and second hinge shafts mounted in connectors, which connect left and right lower control arms to a vehicle body. The first and second hinge shafts rotates as the left and right lower control arms respectively undergo movement, and when one of the hinge shafts is rotated in one direction, and the other is rotated in the opposite direction.
