A mass flow controller includes a base having a first passage, an inlet portion for introducing fluid into the first passage, an outlet portion for releasing the fluid from the first passage, and a second passage branched from a first upstream portion of the first passage and connected to a second downstream portion of the first passage A mass flow sensor is connected to the first passage between the inlet portion of the base and the first portion of the first passage; A first valve is disposed in-line with the first passage between the first and second portions. The first valve controls the mass flow of the fluid passing through the first passage;. A second valve is disposed in-line with the second passage to opens/close the second passage. A valve controller compares the mass flow measured by the mass flow sensor to a standard flow, and then positions the first valve such that the measured mass flow corresponds to the standard flow.

A device for data communications between a Wireless Application Protocol (WAP) terminal and a WAP server, and a data communication method thereof. The data communications device includes: a plurality of WAP terminals each having a protocol stack in which a Circuit Switch Data service (CSD) protocol layer is laid under a Wireless Transaction Protocol (WTP) layer and a Wireless Datagram Protocol (WDP) layer, for generating WAP data which is service request data; a plurality of WAP servers each having a protocol stack in which a Transmission Control Protocol (TCP) layer and an Internet Protocol (IP) layer are laid under a WTP layer and a WDP layer, for providing the WAP terminals with WAP server data according to the WAP data; and an interworking function (IWF) unit having a CSD protocol layer connected to the CSD protocol layers of each WAP terminal, and a TCP layer and an IP layer which are connected to the TCP and IP layers of each WAP server, for mapping the WAP terminals to the corresponding WAP servers, wherein each WAP terminal communicates with the IWF unit though a single Internet Protocol/Peer-to-Peer Protocol (IP/PPP) layer included in its own CSD protocol layer, and the IWF unit communicates through the Internet with each WAP server. Because there is no redundancy of IP/PPP protocol layers in the WAP terminal, overhead is considerably reduced. Also, the IWF unit is directly connected through the Internet to the WAP server, not through the PSTN and the ISP, so that connection time and costs can be reduced.

Device for data communications between wireless application protocol terminal and wireless application server, and method thereof

In a wireless communication system provided with a WAP (wireless application protocol) server which can convert different data and protocols into available data and protocols between the wireless communication system and an Internet server, a method of designating a WAP server address and a wireless communication system are disclosed. The method includes the steps of deciding via a switching system whether the registered position of the wireless communication terminal which requests the registration is changed to another registered position after confirming via the switching system whether the wireless communication terminal is eligible when a wireless communication terminal requests a registration; and answering the registration request and simultaneously transferring the address information of a corresponding WAP server via the switching system to the wireless communication terminal when the registered position of the wireless communication terminal is not changed in the above step, and answering the registration request and simultaneously transferring the address information of a corresponding WAP server via the switching system to the wireless communication terminal when the registered position of the wireless communication terminal is changed in the above step. Consequently, there is an advantage in which, according to the movement of the wireless communication terminal, a corresponding WAP server address is automatically transferred to the wireless communication terminal. The wireless communication system is provided with a WAP server which can convert different data and protocols into available data and protocols between the wireless communication system and an Internet server.
