摘要:
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.

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 multi-channel packet switching apparatus having traffic flow controlling and checking functions which is capable of simply controlling the system and having a simpler construction by concurrently performing a cell copy function and a cell routing function for providing a multi-casting function. The apparatus includes a synchronizing unit for synchronizing the cells recirculated through the recirculation link with the cells newly inputted into the routing unit based on time and providing to the routing unit, a reverse direction flow control requesting unit for counting the number of cells which are recirculated at every cell time and requesting a reverse direction flow control to a traffic providing source when the thusly counted number exceeds a threshold value, a reverse direction buffering control unit for restricting a cell output to the output port through which a request signal is outputted when a reverse direction flow control request signal is received from the traffic receiving source until the request signal is released, an error cell removing unit for removing an error cell based on the routing tag error among the cells from the bypass link by the routing unit within a predetermined time, and a cell loss counting unit for counting the cell loss which are not recirculated by the recirculation path setting unit by the input port.

The present invention relates to a fixed length packet switching apparatus using multiplexers and demultiplexers in which the apparatus has an output buffer-type construction, protects itself from a temporary overflow occurrence of an output terminal and has the construction of the mutual flow control to enhance its entire performance. The present invention can protect the entire operations as well as enhance the entire performance of the switching apparatus by preventing an obstacle of the switching apparatus due to an overflow temporarily generated from an output terminal, process without a loss of excessive cells a traffic phenomenon of one output port in the switching apparatus, reduce the necessary buffer according to the effect of the rate gain and process smoothly input traffic of the internal buffer having a burst characteristic. Further more, the present invention has a duplicate function of cells able to provide a broadcast-type service distributed to subscribers at one time so that the subscribers can receive a distributed service to thereby increase the effectiveness of the channel.

A cathode for an electron tube has a layer of electron-emissive substance containing alkaline earth metal carbonates having capillary crystals, to which 0.01-20.0 wt % of both a lanthanum (La) compound and a magnesium (Mg) compound or an La--Mg compound, based upon the weight of the alkaline earth metal carbonate, is added. The cathode enjoys full interchangeability with a conventional oxide cathode and a 15-20% longer lifetime.

Provided are a virtual computing accelerator and program downloading method for server-based virtual computing. The virtual computing accelerator divides a program allocated to a virtual memory into groups, such as pages or segments, and downloads the groups of program data in sequence. Here, the groups of program data are downloaded after download sequence is estimated on the basis of statistical data accumulated in a hash table, or only a part that must be first downloaded is downloaded in advance. Thus, a program-execution wait time of a client can be reduced. In addition, only a part of a possibly required program is transferred in advance, and the client can execute the application program using only a small amount of virtual memory.

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.
