    • The group page system of the present invention is composed of: portable terminals, broadcast distribution servers that distribute data by broadcast to the portable terminals, and group page identifier servers that manage group page identifiers used by the portable terminals to scan data that have been distributed by broadcast from the broadcast distribution servers. Each portable terminal transmits position information of the portable terminal and network information of the network to which the portable terminal is connected to the group page identifier servers at a prescribed timing for updating. Each group page identifier server specifies the broadcast distribution server that distributes data by broadcast to a portable terminal based on the position information and network information from the portable terminal, and transmits to the portable terminal the group page identifier for scanning data that have been distributed from the broadcast distribution server that has been specified.

    • A hand-shake type control circuit for controlling a data transfer circuit according to the status of a data transfer request signal. The data transfer request signal is initially received at a NAND gate and is also directly coupled to the reset input of are set flip-flop. The output of the NAND gate is used as a first control signal to set the flip-flop and to cause another circuit to activate data transfer. The flip-flop output is a second control signal which is reset only when the transfer request signal changes from an active to an inactive status. The second control signal is coupled to an input of the NAND gate and inactivates the first control signal. Thus, data transfer cannot recur until after the data transfer request signal changes to an inactive status so that parasitic oscillations are eliminated. The flip-flop consists of two, two input NAND gates that are located out of the path of data transfer and that are easier to fabricate than the prior art D flip-flop.
    • 一种用于根据数据传送请求信号的状态控制数据传送电路的握手型控制电路。 数据传送请求信号最初在NAND门处被接收并且也直接耦合到被设置的触发器的复位输入。 NAND门的输出用作第一控制信号以设置触发器并使另一电路激活数据传输。 触发器输出是仅在传送请求信号从活动状态变为非活动状态时才复位的第二控制信号。 第二控制信号耦合到NAND门的输入并使第一控制信号无效。 因此,在数据传输请求信号变为无效状态之后,数据传送不能重复,以便消除寄生振荡。 触发器由两个,两个输入NAND门组成,它们位于数据传输路径之外,并且比现有技术的D触发器更容易制造。
