Abstract: PURPOSE: A method and apparatus routing Internet calls are provided to decrease the congestion of a public switched telephone network caused by the long holding time of Internet calls. CONSTITUTION: A telecommunications network(10) includes a public switched telephone network (PSTN,12) and an Internet data network(14). The Internet data network (14) includes a line access switch(26) coupled to the PSTN and an Internet routing element(24) acting a switching function for Internet calls rerouted from the PSTN(12). The Internet routing element(24) is coupled to end office switches(16) and local switches(18) of the public switched telephone network(12) by modem trunks(30). The modem trunks(30) provide the Internet calls rerouted from the PSTN(12) to Internet routing element(24) in order to prevent the Internet calls from congesting trunks(22) of the PSTN(12). The Internet calls are received at an ATM multiplexer(58) within the Internet routing element (24). The ATM multiplexer(58) includes a pool of modems(60) that converts the analog signal on the modem trunks (30) into digital data. The ATM multiplexer(58) includes an ATM cell adaptation unit(66) that converts the digital data into ATM cells for transmission to an Internet Service Provider(42) over an ATM network(48). The ATM multiplexer(58) generates addressing information for the ATM cells through interworkings with signaling protocols of a signal transfer point network(28) and an SS-7 signaling network(44) in order to determine the destinations for the Internet calls. The line access switch includes a similar ATM multiplexer(94) to reroute Internet calls prior to entering the public switched telephone network(12).

Abstract: PURPOSE: A CVT(continuously variable transmission) is provided to prevent a vehicle from slipping or moving forward even if a driver does not step on a brake pedal during stopping on an inclined road. CONSTITUTION: A CVT is set to have a reduction ratio of 3/4 during stop of a vehicle.

During acceleration, a second clutch(43) is interrupted and a first clutch(41) is connected to convert into a high-speed driving mode if the speed ratio reaches 5/16. The reduction ratio is reduced and the RPM(revolution per minute) of an engine increases if the rotational force starts to be fed through a high-speed passage. Thus, the vehicle is accelerated gradually to reach the highest speed.

Abstract: PURPOSE: A magnetic field generator for a magnetic resonance image apparatus is provided to reinforce permanent magnet and boosting pauses(pole piece calibration method). CONSTITUTION: All magnetic flux passes through a photographing area. The magnetic flux of an ambient permanent magnet(10) combined with a magnetic field clamp(3) does not leak toward a side face of a pole piece(4).

Filed: 1999-06-30
Abstract: PURPOSE: A proximity effect related to a photolithography and an etch processes can solve by only using a mask forming tool when routing a metal pattern. CONSTITUTION: A step is to form the first layer constructed by a via including a plurality of metal patterns. Thereafter, a step is to form a space layer for discriminating whether the separated distance between the metal patterns is less than a constant value. Then, a step is to form the second layer oversized with a width that the first layer is not contacted with the space layer. Next, a step is to form the third layer(49) for discriminating the extent of alignment of the first and second layers. Since the metal patterns being overlapped with a via represents almost the same value, the metal patterns minimizes the overlap of the metal patterns and the via. When a space between metal patterns is larger than 'd', a result oversizing the size of the metal pattern toward X, Y directions can obtain.
