Abstract: PURPOSE: An attenuator for the noise of a vehicle exhaust gas system is provided to improve the contacting structure of a valve opened and closed by the resilience of a spring and exhaust pressure. CONSTITUTION: In case of increasing exhaust gas and pressure in proportion to the output of an engine, exhaust gas passes through a pipe line in a moment to flow into a high pressure chamber(I). The high pressure exhaust gas passes through an inducing pipe(40) in a moment of expanding exhaust pressure. Thus, a valve(50) is opened to discharge exhaust gas outside through a waiting chamber(W) and an outlet pipe(30) for attenuating noise. In case of decreasing exhaust pressure, a spring(70) closes the valve and the outer circumference of the valve is a curved surface so that the frictional noise is minimized.

Abstract: PURPOSE: To find a necessary site in a single local network is not easy during the internet search. The virtual space is easy to access but the access to the real space is limited. As for a local native network, the domain is so hard to distinguish that the domain site is hard to find. CONSTITUTION: The virtual spaces(20,40,60) of the primary domains are divided into many spaces. Then, real spaces(30,50,70) in the secondary domains are produced so that each space in secondary domains corresponds to one of the spaces(20,40,60) in the primary domains. Each separated space(20,40,60) is run by a person in its corresponding real space(30,50,70). Separated virtual spaces are identified with real spaces, and users have access to them. Each of the separated virtual spaces(20,40,60) in the primary domains is once again separated into sub-spaces(20,40,60) and produces its corresponding real space. Users have an easy access to local networks on the Internet and areas with the secondary domains will have the same privilege as the primary domains. Consequentially, they can run local networks with better recognition and better quality at low costs. The secondary domains separated area by area have a strong similarity with the primary domains, providing all users with better access to virtual space and real space, enabling the sharing of information through intimacy among areas, and increasing synergistic effects.
