According to one embodiment, a semiconductor device includes: a first circuit configured to drive a load couplable to a first terminal by supplying a load current to the load; and a third circuit including a second circuit configured to copy the load current based on a first voltage of the first terminal and output a first current obtained by copying the load current, the third circuit being configured to monitor a second current based on the first current. The third circuit further includes a fourth circuit configured to adjust the second current in a case where the load current is not supplied to the load.

Semiconductor device

According to an embodiment, a semiconductor integrated circuit device has a first switching element that is connected between first and second nodes, a second switching element that is connected between the first node and a third node and outputs a current that is 1/K times as much as an output current of the first switching element, and an amplifier that controls, by a signal provided by amplifying a voltage difference between the third node and a fourth node, a conduction state of a third switching element that is connected between the fourth node and a fifth node.

An object is to provide a telephone enabling a user of a telephone to readily recognize which telephone user is a source of voice under transmission. This telephonehas a receiverfor receiving telephone information to specify each of an authorized telephone and unauthorized telephones, a display surfacefor displaying predetermined information based on the received telephone information, and a display control partfor specifying a content of the predetermined information, based on the telephone information received by the receiver, and for displaying the content on the display surface. The display control partfixedly displays user information to specify a user of the authorized telephone, in a partial region of the display surface, and displays at least part of user information to specify users of telephones except for the concerned telephoneamong the authorized telephone and unauthorized telephones, in a remaining region except for the partial region of the display surface

Telephone used in a telephone system for transmitting data from an authorized telephone with speech authority to an unauthorized telephone without speech authority

In a system according to the invention, a communication section of a mobile terminal detects a carrier from an external R/W, starts communication with the external R/W, and acquires content simplified data of contactless card function content from the external R/W. The acquired content simplified data is transferred to a control section using the contactless card function content and stored. Further, in this system, by connecting to a URL contained in the content simplified data, content body data of the contactless card function content corresponding to the content simplified data is downloaded and stored in the mobile terminal.

Mobile terminal device and data acquistion method using the same

An object of the present invention is to be able to rejoin a group call by spontaneous operation from the terminal side at an optional timing. The group call server provides a plurality of mobile communications terminals with a function of a group call between the terminals through a communications network, and comprises: an ID granting unit that grants the group call to be established a call ID that identifies the group call; an ID notification unit that gives the terminals participating in the group call to be established the call ID granted to the group call by the ID granting unit; a rejoin request receiving unit that receives requests to rejoin the group call that have been transmitted from a terminal disconnected from the group call and that include the call ID; and a rejoin control unit that allows the terminal that transmitted the request to rejoin the group call related to the call ID included in the rejoin request received by the rejoin request receiving unit.
