    • In a radio paging receiver in which a CPU (6) stores a received message in one of message areas of a message memory (8) as an unconfirmed message and in which an announcing section (11-18) carries out a call announcement in response to the received message, the CPU makes the announcing section announce an unconfirmed message full announcement instead of the call announcement when each message area is filled with the unconfirmed message and when an announcement stop instruction is not received from a keyboard (10) within a predetermined time interval from a time instant at which the call announcement is started. The unconfirmed message full announcement has an announcing pattern which is different from that of the call announcement. When the instruction is received within the predetermined time interval, the CPU makes the announcing section stop the call announcement and makes the message memory memorize the received message in the above-mentioned one of the message areas as a confirmed message instead of the unconfirmed message.
    • 在无线寻呼接收机中,CPU(6)将接收到的消息存储在消息存储器(8)的一个消息区域中作为未确认消息,并且其中通知部分(11-18)响应于执行呼叫通知 对于所接收的消息,当每个消息区域填充有未确认消息时,CPU使通知部分通知未确认消息完整通知而不是呼叫通知,并且当在预定的消息内没有从键盘(10)接收到通知停止指令时, 从呼叫公告开始的时刻开始的时间间隔。 未经确认的消息完整公告具有与呼叫公告不同的通告模式。 当在预定时间间隔内接收到指令时,CPU使通知部分停止呼叫通知,并使消息存储器将上述一个消息区域中的接收消息存储为确认消息而不是未确认消息。

    • A selective calling radio receiver includes a message memory for distinguishably storing the message as non-read message and read message, and a control portion. The control portion performs a non-read alarm when the non-read message is stored in the message memory and a normal alarm when there is no non-read message stored therein. The control portion also has a function of performing a call alarm termination and display of message and storing the message in the message memory as a read message when a switch for requesting termination of the call alarm is pushed at a time of a call alarm and terminating the call alarm and storing the message in the message memory as a non-read message when the switch is not operate after a specific period of time.

    • A transistor circuit that ensures signal transmission between adjoining direct-coupled stages at a low supply voltage even when an input signal is in a high level. This transistor circuit is comprised of a first stage having a first transistor and a first load connected to a collector or drain of the first transistor, and a second stage having a second transistor. An input voltage is applied to a base or gate of the first transistor in the first stage. The first transistor produces a first output current flowing through the first load according to the input voltage, thereby outputting a first output voltage at the collector or drain of the first transistor The first output voltage from the first stage is applied to a base or gate of the second transistor in the second stage without using any coupling capacitor. The first load has a variable resistance responsive to a magnitude of a dc component of the first output current. When the magnitude of the dc component of the first output current is increased from a predetermined value due to a magnitude increase of the input voltage, thereby decreasing a magnitude of a dc component of the first output voltage, the variable resistance of the first load is decreased so as to compensate the decreased magnitude of the dc component of the first output voltage. The effect caused by the operating point shift is compensated.
    • 晶体管电路即使在输入信号处于高电平时也能保证在低电源电压下相邻的直接耦合级之间的信号传输。 该晶体管电路包括具有第一晶体管和连接到第一晶体管的集电极或漏极的第一负载的第一级,以及具有第二晶体管的第二级。 在第一级中将第一晶体管的基极或栅极施加输入电压。 第一晶体管根据输入电压产生流过第一负载的第一输出电流,从而在第一晶体管的集电极或漏极处输出第一输出电压。来自第一级的第一输出电压施加到第一级的基极或栅极 第二级的第二晶体管不使用任何耦合电容器。 第一负载具有响应于第一输出电流的直流分量的幅度的可变电阻。 当第一输出电流的直流分量的大小由于输入电压的幅度增加而从预定值增加时,从而减小第一输出电压的直流分量的大小,第一负载的可变电阻为 减小,以补偿第一输出电压的直流分量的减小幅度。 由操作点偏移引起的影响得到补偿。
