    • A communication system for performing bidirectional communications substantially simultaneously between a telephone line and a radio communication system by using a single-frequency carrier. A base station includes a first radio transceiver and a line connector disposed between the first radio transceiver and the telephone line. A terminal station includes a second radio transceiver. Each of the first and second radio transceivers has a control unit, a transmitter unit including a signal compressor, a synchronizing signal generator and a modulator, and a receiver unit including a signal expander. The control unit sets the line connector to an interconnecting state in response to a connection request signal from the telephone line or the terminal station, while establishes a communication enabling state between the telephone line and the terminal station during a connection processing period. After the communication enabling state has been set up, a speech enabling state is established between the telephone line and the terminal station. The connection processing period is changed over to a speech period after the communication enable state has been established, to thereby allow communication between the telephone line and the terminal station.
    • 一种用于通过使用单频载波在电话线和无线电通信系统之间基本上同时执行双向通信的通信系统。 基站包括第一无线电收发器和设置在第一无线电收发器和电话线之间的线路连接器。 终端包括第二无线电收发器。 第一和第二无线电收发机中的每一个具有控制单元,包括信号压缩器,同步信号发生器和调制器的发送器单元,以及包括信号扩展器的接收器单元。 控制单元响应于来自电话线路或终端站的连接请求信号将线路连接器设置为互连状态,同时在连接处理期间建立电话线路与终端站之间的通信使能状态。 在通信使能状态已经建立之后,在电话线和终端站之间建立语音使能状态。 在通信使能状态已经建立之后,将连接处理时段切换到语音周期,从而允许电话线路与终端站之间的通信。

    • In radio communication system in which single frequency simultaneous transmission and reception is performed, a speech audio signal is divided by a predetermined time interval. A transmission time and a reception time are allotted in the predetermined time. A time-compressed signal is transmitted during the transmission time, and a time-compressed signal transmitted from other transceiver is received during the reception time and it is decompressed to the original length. The transmission time and the reception time are alternately repeated to transmit and receive the audio signals substantially simultaneously by a single frequency, and the audio signal is reproduced from the received signal. When communication with a telephone set is to be established, a DTMF signal is used as a dialing signal to call the telephone set from the transceiver. The DTMF signal is time-compressed and then transmitted along with the speech signal. A transmission timing of the DTMF signal is controlled, and the generated DTMF signal is temporarily stored in a memory. When the transmission of the DTMF signal can be completed before the transmission time is switched to the reception time is determined, and if it can, the DTMF signal is read from the memory and transmitted.
    • 在执行单频同时发送和接收的无线电通信系统中,语音音频信号被划分预定的时间间隔。 传输时间和接收时间在预定时间内被分配。 在发送时间期间发送时间压缩信号,并且在接收时间期间接收从其他收发器发送的时间压缩信号,并将其解压缩为原始长度。 交替地重复发送时间和接收时间,以单个频率基本上同时发送和接收音频信号,并且从接收到的信号再现音频信号。 要建立与电话机的通信时,将使用DTMF信号作为从收发机呼叫电话机的拨号信号。 DTMF信号被时间压缩,然后与语音信号一起传输。 控制DTMF信号的发送定时,将生成的DTMF信号暂时存储在存储器中。 当在传输时间切换到接收时间之前可以完成DTMF信号的传输,并且如果可以,则从存储器读取DTMF信号并发送。

    • A tanker which can reliably prevent the outflow of cargo oil from cargo oil tank sections (1, 2, 105, 106) in the ship body in the event of damage or injury to an outer plate (8, 9) of the ship body has a double-sided hull construction (4, 104) arranged on opposite sides of each cargo oil tank in the ship's body and a mid-height deck (3, 118) arranged to divide each cargo oil tank into an upper cargo oil tank (2, 106) and a lower cargo oil tank (1, 105). To reliably prevent the outflow of cargo oil in the event of damage or injury to the ship body due to stranding, collision or similar malfunction, the height (H) of the mid-height deck (1, 118) as measured from the ship bottom (8, 108) is determined so that the pressure of cargo oil exerted on an outer plate of the ship's side wall will not be higher than the pressure of sea water. An access trunk (5, 112) and pressure control devices (6, 7, 113, 114) serve for degassing cargo tank sections.
