Title: Method for establishing communication link between different networks
Inventor: YUN IN HO
IPC: H04L12/28
Filed: 1998-11-27
Abstract: PURPOSE: A method for establishing a communication link between different networks is provided to reduce dependency on the communication agreement of an external PSTN network not to changer the agreement of inner network even if the communication agreement of PSTN network is changed. CONSTITUTION: A message demanding connection is transferred to a gateway through a signal channel in an inner network. Then, the gateway receiving the message demanding connection establishes a link between an outer and an inner network for opening a voice channel, and signal inputted through the voice channel of the outer network is packetted in the gateway for being inputted to the inner network. A target address outputted from the inner network through a signal channel is converted into a certain signal in the gateway for outputting to the outer network. And, a ring back tone or a busy tone of the outer network is packetted to be transferred to the voice channel in the inner network. When a voice is inputted, the voice is packetted for being transferred to the voice channel of the inner network. When the inner network receives connection refusal signal, a connection releasing message is transferred to the gateway for closing the voice channel and for releasing the link to the outer network.

Title: Siloxan compound, producing method thereof, and liquid composition containing the compound
Inventor: DANAKA SEIICHIRO
IPC: C09D183/02
Filed: 1997-03-25
Abstract: PURPOSE: When conventional siloxane compounds are used for coating after being preserved for longer time than decided time, properties of the coating, such as hardness and resistance for boiling water, are deteriorated. The reason of the deterioration is that a silanol-substrate reactive functional group is reduced by slow polymerization reaction due to the high reactivity of the silanol group in the compound. Therefore the utility of the siloxane compound may be improved significantly if the improvement of their stability in the liquid state is possible. CONSTITUTION: Siloxane compound has high degree of polymerization and high storage stability because it can be maintained in transparent liquid state over 1 year without causing the compositional change. The compound can be used for hard coating in the form of hydrolyzed solution. And because compatibility with various type of organic compound such as resin is superior, the siloxane compound may be used to give hydrophile to a coating formed by hardening liquid composition by mixing the siloxane compound with the compatible organic compound, or to improve properties of the coating such as contamination resistance, acid resistance, chemical resistance, weather resistance and heat resistance. In formula, R1 is methyl or ethyl, and R2 is organic group different from R1.
