There is provided a vehicle seat including: a seatback formed with a penetrating portion that penetrates from a front face side to a back face side; a placement member that is attached to the seatback so as to be capable of moving between a housed position housed inside the penetrating portion and closing off the penetrating portion and a lowered position lowered from the housed position towards the front side; and a flexible opening and closing member that is attached to the seatback and is capable of opening the penetrating portion and closing off the penetrating portion from the seatback back face side.

Vehicle seat

There is provided a vehicle seat including: a framework member that structures a framework of a seatback; a center rear face cover that structures a central portion of a rear face of the seatback; a side rear face cover that structures the seat width direction side portion; an overlap portion at which an end portion of the center rear face cover and an end portion of the side rear face cover are sewn together in an overlapping state, and extending to a seat forward side; an anchor member that is disposed at the overlap portion and that is anchored at the framework member and pulls the overlap portion in to the seat forward side; and a restraining portion that joins at least one of the overlap portion and the anchor member to the framework member, and restrains movement of the overlap portion.

A call agent (CA) connects a IP telephone and a public switching telephone on the basis of a called-destination telephone number which corresponds to received reverse-charging service number from the IP telephone; a reverse-charging service control apparatus causes an exchange to stop charging; the CA and the reverse-charging service control apparatus calculate a charging information items, respectively; and generate a fee information by setting a charged party information so that a sum of fees in an IP network and a public switching telephone network may be charged to the called-destination telephone number, and transmit the fee information to an IP/PSTN charging management apparatus on a called destination side; and generate other fee information so that a fee in the network on a call origination side may be charged to a business company of called destination, and transmit the fee information to the apparatus on a call origination side.

Reverse charging system, reverse-charging service control apparatus, call agent and reverse charging method

A media gateway built in an exchange comprises a media gateway control unit connected to a control unit of the exchange, a first protocol processing unit for executing a call connection procedure according to a first call control protocol with an IP call connection controller on the IP network, and a second protocol processing unit for executing a call connection procedure according to a second call control protocol with the IP call connection controller. The media gateway control unit instructs the first protocol processing unit to start call connection processing in response to a call connection command from a PSTN telephone, aborts the call connection processing of the first protocol processing unit when receiving a connection protocol change command from the IP call connection controller before completing the call connection according to the first protocol, and instructs the second protocol processing unit to execute call connection processing.

Media gateway and automatic telephone call redirecting service system

A telephone applicable to PSTN and IP network having functions of obtaining, when a call is originated by entering a PSTN telephone number, an IP network telephone number of a destination telephone corresponding to the PSTN telephone number from a telephone number translation server connected to the IP network, obtaining IP address information of the destination telephone corresponding to the IP network telephone number from a call agent connected to the IP network, establishing call connection with the destination telephone via the IP network by using the IP address information, and establishing call connection with the destination telephone via the PSTN if the IP network telephone number of the destination telephone cannot be obtained from the telephone number translation server.

Telephone applicable to PSTN and IP network and call connection control method

A call agent(CA) connects a IP telephone and a public switching telephone on the basis of a called-destination telephone number which corresponds to received reverse-charging service number from the IP telephone; a reverse-charging service control apparatus causes an exchange to stop charging; the CA and the reverse-charging service control apparatus calculate a charging information items, respectively; and generate a fee information by setting a charged party information so that a sum of fees in an IP network and a public switching telephone network may be charged to the called-destination telephone number, and transmit the fee information to an IP/PSTN charging management apparatus on a called destination side; and generate other fee information so that a fee in the network on a call origination side may be charged to a business company of called destination, and transmit the fee information to the apparatus on a call origination side.
