    • A source device 10 transmits streaming data. In a packet receiver 22 of a sync device 20, statistical data acquirer 23 calculates statistical data such as one-way delay time, packet loss ratio, reception rate and the like from the received streaming data and transmits it to the source device. The statistical information received by source device 20 is extracted by a packet receiver 15 and input to a channel band estimator 16. The channel band estimator 16 gives encoder 11 instructions to provide optimal encoding based on the transmission delay. Upon this, the transmission delay is calculated by assuming the minimum value of the communication delay from the start of transmission as zero. Control is performed by determining the delay time and packet loss ratio in data transmission and considering, based on these, the channel quality and bandwidth margin, so as to provide the optimal transmission bit rate or encoding rate.
    • 源装置10发送流数据。 在同步装置20的分组接收机22中,统计数据获取部23从接收到的流数据中计算单向延迟时间,分组丢失率,接收速率等统计数据,并将其发送到源设备。 由源设备20接收的统计信息由分组接收器15提取并输入到信道频带估计器16.信道频带估计器16给编码器11指令提供基于传输延迟的最佳编码。 这样,通过将从发送开始的通信延迟的最小值设为零来计算传输延迟。 通过确定数据传输中的延迟时间和丢包率来进行控制,并且基于这些,考虑信道质量和带宽裕度,从而提供最佳传输比特率或编码率。

    • A transmission method uses multiple kinds of control codes to be exchanged on a serial transmission path between a sender side and a receiver side, and each of the multiple kinds of control codes has bits smaller in number than a predetermined fixed length. The transmission method includes the steps of inspecting the received bit string in groups of bits of the number of the control code, and thereby determining whether one of the multiple kinds of control codes is present in the serial signal received on the serial transmission path or not, selecting the control code to be sent based on a result of the determination in the determining step, sending, onto the serial transmission path, a bit string containing at least the control code to be sent based on the result of the determination in the determining step, and receiving the data code by inspecting the received bit string in groups of bits of the fixed length in response to the detection of the control code indicating the start of transmission of the data from the opposite side in the determining step.

    • A fuel vapor treatment device or canister for a vehicle evaporative emission control system has a casing filled with a fuel vapor absorbent material in its chamber. A relay pipe projects outwardly from one end the casing and communicates with the chamber. A liquid-fuel separator having a cavity is sealingly mounted to the one end of the casing so that the relay pipe extends into the cavity. Inlet and outlet pipes, which communicate with the cavity and fuel vapor, are formed in the separator. A fuel vapor outflow passage is formed inside the separator and communicates with the outlet pipe. The suction pipe has a reduced size section with an orifice. A liquid-fuel suction pipe, which communicates with the outflow passage through the orifice, extends perpendicularly downwardly from the outflow passage. The suction pipe extends from the orifice to the area where the liquid-fuel collects.
