    • The present invention relates to a loop network arranged by loop-connecting a control station and a number of substations through a main transmission path where at least one of the substations comprises a branch station inserting and coupling another station into the main transmission path as a lobe or subloop. In order to prevent an out-of-step condition of the main transmission path, resulting from a failure in the lobe or subloop, the branch station includes a frame buffer for normally selecting the signal from the lobe or subloop and selecting the signal from the main transmission path during detection of a failure and on a bypass command, and for accumulating the selected signal in units of a single frame, and a mechanism for supplying the accumulated signal to the main transmission path.

    • A communication terminal apparatus is separated into a housing that is capable of video/voice communications, and a housing that is capable of only voice communications. Since functions of the housing that is capable of only the voice communications are limited, the housing becomes small, can be stored in a pocket or the like, and can immediately go off-hook upon reception of an incoming call. Upon reception of a videophone communication request, the user goes off-hook using the housing that is capable of only the voice communications to immediately make voice communications with the partner terminal, and can switch the communication mode to the video/voice communications using the housing that is capable of the video/voice communications, as needed. Hence, even a communication terminal having a videophone function can comprise a video input/output function without impairing its portability and storability.
    • 通信终端装置被分离成能够进行视频/语音通信的外壳以及仅能进行语音通信的外壳。 由于仅能够进行语音通信的外壳的功能受到限制,所以外壳变小,可以存储在口袋等中,并且能够在接收到来电时立即摘机。 在接收到可视电话通信请求时,用户仅使用语音通信的外壳即可摘机,立即与对方终端进行语音通信,并且可以使用该外壳切换到视频/语音通信 根据需要能够进行视频/语音通信。 因此,即使具有可视电话功能的通信终端也可以包含视频输入/输出功能,而不损害其便携性和可存储性。

    • According to one embodiment, a memory device includes a nonvolatile memory which stores data in units of a write unit includes cells, and a controller which controls the memory and partitions memory space of the memory. In response to a request to write write-data to the memory from a host, the controller requests the host to transmit a segment of the write-data with a specified size. The write-data segment has a size of an integral multiple of a size determined to allow for a set of the write-data segment and corresponding additional data to be the largest while smaller than the write unit. Before completion of processing a first command which requests access to a first partition, the controller accepts a second command which requests access to a second partition.

    • An improved time slot allocation method for a loop network. Loop networks in which the present invention is applied include a loop-connecting a control station and a number of branch stations. The control and branch stations each have at least one terminal connected thereto such that interstation communication, when demanded by a terminal, is made by passing a frame through the transmission path. The frame includes a synchronization area for indicating the leading end of the frame, a fixed-length control area, and a data area composed of a plurality of time slots. According to the invention, the control and branch stations are each allocated with a predetermined or unique number of time slots to be used by terminals for interstation communication. When a station has its reserve of unused time slots fall below a preset lower limit, the control station supplements time slots from its own reserve. On the other hand, if a station has its reserve exceed a preset upper limit, the station returns the excess time slots to the control station. Thus, wait times for a communication demand before a line connection is established are reduced, with enhanced control station response. Also, efficiency of time slot use is enhanced, with a considerable reduction in call losses.
    • 用于环路网络的改进的时隙分配方法。 应用本发明的环路网络包括环路连接控制站和多个分支站。 控制站和分支站各自具有至少一个连接到其上的终端,使得当由终端请求时,通过使帧通过传输路径来进行站间通信。 帧包括用于指示帧的前端的同步区,固定长度的控制区和由多个时隙组成的数据区。 根据本发明,控制站和分支站各被分配有预定或唯一数量的时隙,以由终端用于站间通信。 当车站的未使用时隙的储备量低于预设下限时,控制站从其自己的储备中补充时隙。 另一方面,如果站的预留超过预设的上限,则站返回到控制站的超时隙。 因此,在建立线路连接之前的通信需求的等待时间减少,具有增强的控制站响应。 此外,增强了时隙使用的效率,大大减少了呼叫损失。
