    摘要： A semiconductor laser comprises a sapphire substrate, an AlN buffer layer, Si-doped GaN n-layer, Si-doped Al0.1Ga0.9N n-cladding layer, Si-doped GaN n-guide layer, an active layer having multiple quantum well (MQW) structure in which about 35 Å in thickness of GaN barrier layer 62 and about 35 Å in thickness of Ga0.95In0.55N well layer 61 are laminated alternately, Mg-doped GaN p-guide layer, Mg-doped Al0.25Ga0.75N p-layer, Mg-doped Al0.1Ga0.9N p-cladding layer, and Mg-doped GaN p-contact layer are formed successively thereon. A ridged hole injection part B which contacts to a ridged laser cavity part A is formed to have the same width as the width w of an Ni electrode. Because the p-layer has a larger aluminum composition, etching rate becomes smaller and that can prevent from damaging the p-guide layer in this etching process.

    摘要： A CPU sets one of first and second memories as an "active system memory" and the other as a "standby system memory". Data about a combination of the VPI/VCI and TAG data is registered in and deleted from only the memory set as the "active system memory". The CPU, only when a null entry exists in a position satisfying a VPI/VCI increasing sequence with an increased address value, registers this null entry in the active system memory with data about new combination of the VPI/VCI and the TAG data. Whereas if there is no such null entry, the CPU reads the data about all the combinations of the VPI/VCI and the TAG data which are registered in the active system memory, re-sorts the read data and the data about the new combinations in the VPI/VCI increasing sequence and write the data from the head address in the standby system memory in a sorting sequence. The CPU, when finishing this writing process, resets the memory so far working as the standby system to an active system memory and the memory so far working as the active system to a standby system memory.

    摘要翻译： CPU将第一和第二存储器之一设置为“活动系统存储器”，将另一个设置为“备用系统存储器”。 关于VPI / VCI和TAG数据的组合的数据被登记在仅作为“活动系统存储器”的存储器中并从其中删除。 CPU只有当满足具有增加的地址值的VPI / VCI增加序列的位置中存在空条目时，才会向活动系统存储器中注册有关VPI / VCI和TAG数据的新组合的数据。 而如果没有这样的空条目，则CPU读取关于在活动系统存储器中注册的VPI / VCI和TAG数据的所有组合的数据，将读取的数据和关于新组合的数据重新排序 VPI / VCI增加序列，并以排序顺序从备用系统存储器中的头地址写入数据。 CPU在完成此写入过程时，将到目前为止的内存重置为备用系统到活动系统内存，并将存储器作为当前系统工作到备用系统内存。

    摘要： A packet data and a header added to a head of the packet data for specifying a transfer condition of the packet data are divided together to data blocks (DBs) each having a designated data length, consisting of an initial DB including the header and an initial part of the packet data, intermediate DBs each including an intermediate part of the packet data and a last DB including a last part of the packet data, so as to be transferred to a data transfer destination in a data processor of a switching system in accordance with write commands for the initial, intermediate and last DBs respectively, and a read command for asking whether the DBs are correctly transferred is sent to the data transfer destination once, after the DBs are transferred. When the DBs are transferred, the packet data is restored at the data transfer destination only by synthesizing the transferred DBs and removing the header.

    摘要： (1) Base stations are divided into base station groups which do not mutually interfere with one another. (2) Priorities of the use of channels are set for each base station group, and each base station holds a priority table showing the priorities of the use of channels. (3) Each base station derives a channel to request, and informs about the channel to adjacent base stations. (4) When the requested channel of the base station overlaps with a requested channel of the adjacent base station, each base station refers to the priority table and autonomously judges whether the requested channel can be used or not. Therefore, it is no longer necessary to wait for a response to the requested message or to confirm with the adjacent base stations regarding the availability of channels, and reduction of the throughputs and prompt channel allocation are possible.
