    • In a radio station system utilizing multi-channel transmission and reception frequencies of the type comprising a transmitter and a receiver wherein the frequency difference between the transmission and reception frequencies is made to be equal to an intermediate frequency, there is provided a source of multi-frequency signal which determines the multi-channel transmission and reception frequencies. The output of the multi-frequency signal source is utilized directly as a local oscillation signal of the receiver and the frequency of the output of the multi-frequency signal source is shifted by a modulated wave having a frequency twice the intermediate frequency and the frequency shifted output is utilized as the transmission frequency.
    • 在使用包括发射机和接收机的类型的多信道发射和接收频率的无线电台站系统中,其中使发射和接收频率之间的频率差等于中间频率, 确定多频道发送和接收频率的频率信号。 多频信号源的输出被直接用作接收机的本地振荡信号,并且多频信号源的输出频率偏移了频率为中频和频偏两倍的调制波 输出用作传输频率。

    • A mobile data receiving system for a mobile communication system is disclosed. A clock signal for a digital phase synchronization loop circuit used for receiving digital data such as a dial number is obtained by multiplying or dividing the frequency of the output signal of a highly-stable oscillator for generating a reference frequency for a frequency synthesizer. Also, noise which is generated by the operation of the digital phase synchronization loop circuit is prevented from deteriorating the performance of the transmitter-receiver by the use of a matching circuit located between the frequency multiplier or divider and the digital phase synchronization loop circuit.

    • A control apparatus for an air conditioning system has an outdoor unit with a compressor, a condenser and a plurality of motorized valves installed to a plurality of branch pipings. A plurality of indoor units having, a plurality of indoor thermoswitches, a microcomputer, and a drive circuit for driving the motorized valves according to the output from the microcomputer are also provided for the control apparatus. The microcomputer counts the number of indoor units required for operation by receiving the output from the indoor thermoswitch. The microcomputer also controls the opening of the motorized valves by predetermined opening steps, according to the result of the counting and with reference to an opening table. The opening table relates the number of indoor units required for operation with the opening of each of the motorized valves. The control apparatus thus permits an optimum distribution of refrigerant to the indoor units to be set quickly.
    • 一种用于空调系统的控制装置,具有一个带有压缩机,冷凝器和安装在多个支管上的多个电动阀的室外机。 还提供了具有多个室内热交换器,微型计算机和用于根据微型计算机的输出驱动电动阀的驱动电路的多个室内单元。 微型计算机通过接收室内热敏开关的输出来计算操作所需的室内机数量。 微型计算机还根据计数的结果并参考打开台,通过预定的打开步骤来控制电动阀的打开。 开启表涉及操作所需的室内机与每个电动阀的打开的数量。 因此,控制装置允许制冷剂到室内单元的最佳分配被快速设定。
