Abstract: PURPOSE: A memory system having a close circuit data line bus structure is provided to maintain the signal transmission time constant regardless of the physical distance between the memory controller and each semiconductor memory apparatus. CONSTITUTION: In a data line structure for a memory system, the memory system(100) includes four semiconductor memory sets(101-104) all synchronizing with a clock signal(CLK) and a memory controller(110) controlling those memories(101-104). The controller(110) commands to write data into those memories(101-104) or read data out of those memories(101-104) through a data line(DQ). And this series of operation synchronize with the clock signal(CLK). Here, the data line(DQ) has a closed structure. The closed loop starts from the data transmitting line(TDQ) of the memory controller(110), continues to the data line(DQ) of each memory set(101-104) and ends at the data receiving line(RDQ) of the controller(110). Thus, the controller(110) has a pair of buffers between the controller(110) and the data transmitting and receiving lines(TDQ,RDQ) respectively.

Abstract: PURPOSE: A discharge valve assembly is provided to prevent the counterflow of discharged gas to a discharge port when closing the discharge valve. CONSTITUTION: A piston(P) moves to a top dead center for compressing the gas filled in a cylinder(C). The gas pushes a discharge valve(120) upward for opening a discharge port. The gas is discharged through the discharge port for filling a discharge space(S). The piston is moved to a bottom dead center for lowering the discharge valve. Thus, the discharge port is closed. Herein, the discharge valve contains a volume part(121) for being inserted into the discharge port. Therefore, the dead volume of the discharge port is reduced. Moreover, a flange part(122) is formed on the upper side of the volume part to be attached on the outer surface of the discharge port. By the flange part receiving the restoring force of a valve spring(130) when closing the discharge port, the closed speed of the discharge valve is increased. In case of the generation of the counterflow of compressed gas to the cylinder, the gas pushes the flange part of the discharge valve for increasing the closed speed of the discharge valve.
