A semiconductor device capable of preventing defective embedding of an insulator and improving the withstand voltage of an element isolation region is obtained. The network switches may be controlled by a controller such as a controller server. A pre-programmed processor receives pressure and flow signals from transducers monitoring the liquid line. The support member is connected to the connecting element in that the first flexural spring is firmly attached with its one end to the support member and with its other end to the connecting element. The text message gateway also converts the delivery request into a SIP request that encapsulates the AO text message, inserts the correlation ID in the SIP request, and transmits the SIP request to the UE.
