A communication terminal () including a first communication unit () and a second communication unit () includes a presence status detection unit () that detects a presence status indicating whether a distance from a personal computer () is inside a communication range where communication is possible or outside the communication range where communication is not possible for each of the first communication unit () and the second communication unit (), and a communication status management unit () that, in accordance with the presence status of either communication unit () detected by the presence status detection unit (), causes the other communication unit () to transition to an activation state, a standby state or a disconnection state.

Communication terminal and communication control method

A communication terminal () including a first communication unit () and a second communication unit () with a shorter communication distance than the first communication unit () includes a presence status detection unit () that detects that a distance from a personal computer () has changed from a state possible to communicate to a state not possible to communicate for the second communication unit (), and a communication status control unit () that causes a standby interval in intermittent reception performed by the first communication unit () to become shorter when a change of the second communication unit () from the state possible to communicate to the state not possible to communicate is detected by the presence status detection unit (). This enables more detailed and accurate tracking of the connection status of the first communication unit (), which can advance the timing to bring the first communication unit () to transition to a disconnection state or a standby state, allowing reduction of power consumption in the first communication unit ().

An object of the present invention is suppressing a mail transmission loop between the communication terminals. A communication terminalaccording to the present invention includes: a communication unitfor receiving a mail from a transmitter; a flag confirming unitfor confirming whether an automatic reply flag is attached or not to the received mail; an automatic reply time confirming unitfor confirming the number of times of automatic replies; an automatic reply determining unitfor determining whether to perform the automatic reply function or not based on presence or absence of the automatic reply flag and the number of times of automatic replies; and a mail transmitting unitfor transmitting the automatic reply mail to the transmitter when the automatic reply function is determined to be performed; wherein the number of times of automatic replies is changed every time the automatic reply function is performed, and when the automatic reply flag is attached to the received mail and the number of times of automatic replies reaches a given value with respect to the received mail, the automatic reply determining unitdetermines not to perform the automatic reply function.

Communication terminal and mail return method

Information transmission requests are delivered to communication terminals existing in a specific area, to collect information held in the communication terminals, without inducing congestion. In an information collecting device included in an information collecting system, terminal information and capacity information are acquired based on base station identifying information, and information of an information amount of collected information is further acquired based on a collected information type that identifies a type of the collected information. In an information collection controlling unit, transmission timing information, designating the timing at which a capacity of performing communication via a base station is not exceeded, is generated based on the terminal information, the information-amount information and the capacity information, and an information transmission request including the transmission timing information is delivered to a communication terminal.

Information collecting system, communication terminal and information collecting method

Non-reception-controlled area information is stored in the non-reception-controlled area storage section of the reception control device for each mobile device ID. When the reception control device receives the disconnection signal and position information from the mobile device in accordance with the mobile device moving away from the key terminal, the presence/absence determination section determines whether or not the mobile device is within the aforementioned area. As a result of the determination, if the current position of the mobile device is within the aforementioned area, control for enabling reception for the mobile device is performed, and if the current position is outside the aforementioned area, control for disabling reception for the mobile device is performed.

Simulcast phase synchronization system

A thick-film integrated circuit device comprises an insulating substrate, first and second conductors, formed on the insulating substrate by means of a thick-film forming method and spaced apart from each other, and a resistance-trimming resistor and a function-trimming resistor, both formed on the insulating substrate by means of the thick-film forming method. Both resistors are rectangular strips. The resistance-trimming resistor has two ends overlapping and thus electrically connected to the facing ends of the first and second conductors, respectively. The function-trimming resistor extends perpendicular to the second conductor, and has one end portion which extends at right angles to, overlaps and is therefore electrically coupled to the thin intermediate portion of the second conductor. A laser beam is applied onto the resistance-trimming resistor, while the resistance between those ends of the first and second conductors which face away from each other is being measured, thereby cutting a notch in the function-trimming resistor and thus greatly adjusting this resistance. A laser beam is applied onto the function-trimming resistor, thereby cutting a notch therein, cutting the resistor into two parts, and thus minutely adjusting the resistance between said ends of the first and second conductors.
