摘要： An aerosol of a powder composed of helium carrier gas and particles of a hexagonal aluminum nitride is charged through a transfer pipe 3 into a film deposition chamber 4 whose interior is depressurized by gas evacuation using a vacuum pump 5 to maintain a degree of vacuum of 200-8000 Pa during supply of the carrier gas and the aerosol is blown from a nozzle 6 provided on the end of the transfer pipe 3 inside the film deposition chamber 4 to impinge on a substrate fastened to a substrate holder 7 to make the impact force of the particles at collision with the substrate 4 GPa or greater, thereby transforming the crystal structure of the aluminum nitride from hexagonal to cubic to deposit cubic aluminum nitride on the substrate. As a result, a method of transforming the crystal structure of a Group XIII nitride is provided that enables transformation of a Group XIII nitride to cubic crystal structure using a system of simpler configuration than that used for transforming the crystal structure of a Group XIII nitride by a static pressure application process.

摘要： If the communication partner of a client node (A1a) is an encryption communication target node (C1), a DNS Proxy unit (A12a) in the client node rewrites a response to a name resolution request for the communication partner node of an application from the actual IP address of the communication partner node to a loopback address that changes depending on the communication partner. On the basis of the destination loopback address of a data packet transmitted from the application, a communication encryption module (A13a) in the client node identifies the communication partner and the encryption communication path to be used for communication with the communication partner. Hence, encryption communication can simultaneously be executed directly with a plurality of communication partner nodes by using the communication encryption module that operates as an independent process.
摘要翻译：如果客户端节点（A1a）的通信伙伴是加密通信目标节点（C1），则客户机节点中的DNS代理单元（A12a）重写对通信伙伴节点的名称解析请求的响应从通信伙伴节点的实际IP地址到根据通信伙伴而改变的环回地址的应用。基于从应用发送的数据分组的目的地环回地址，客户端节点中的通信加密模块（A13a）识别通信伙伴和用于与通信伙伴进行通信的加密通信路径。因此，通过使用作为独立进程操作的通信加密模块，可以与多个通信伙伴节点直接同时执行加密通信。

摘要： In an interdomain network path control, by making path information with a network resource in a destination domain accessible in addition to path information with transmission domain and interdomain network resources, path selection taking network resources into consideration end to end is enabled and optimum path selection not only in a transmission direction but also in a reception direction is also enabled. Moreover, by making not only network resources but also processing load information of a service node accessible, selection of an optimum server and optimum path selection for the server are enabled using both the service node processing load information and the network resources.

摘要： In a connection-oriented network, a route table and a network resource table are provided in a source node which updates the network resource table in response to a topology state message which is flooded through the network whenever there is a change in the available network resources. The source node updates the network resource table in response to an early-arriving trouble report message from the network if such a change in the available network resources occurs when a connection is being progressively established or already established from the source node. In response to a connection setup message, the source node fetches a route from the route table and compares a user's requirement such as quality and/or bandwidth with the resource data of the fetched route stored in the network resource table. A connection is established via the fetched route if the resource data of the fetched route in the network resource table indicates that the fetched route can support the requirement.

摘要： An ATM terminal transmits an NHRP packet to an NHS based on an ANYCAST address thereof. A NHRP configuration server may be placed in the ATM network to hold NHS information in order to store the configuration, acquire an IP address and an ATM address of the NHS, and transmit the NHRP packet based on the acquired address. Each NHS is allowed to register its own information in the NHRP configuration server at a regular interval or when the information has been updated. When the NHS receives an NHRP register packet from an ATM terminal that is not managed thereby, the NHRP register packet is transferred to another NHS that manages the ATM terminal. The NHS may also execute authentication operation with respect to the NHRP register packet transferred from the ATM terminal that is managed thereby.
摘要翻译： ATM终端基于其ANYCAST地址向NHS发送NHRP分组。可以将NHRP配置服务器放置在ATM网络中以保存NHS信息以便存储配置，获取NHS的IP地址和ATM地址，并且基于所获取的地址来发送NHRP分组。允许每个NHS定期在NHRP配置服务器中注册自己的信息，或者当信息被更新时。当NHS收到来自未被管理的ATM终端的NHRP注册报文时，NHRP注册报文被转移到管理ATM终端的另一个NHS。 NHS还可以对从由其管理的ATM终端传送的NHRP注册包进行认证操作。

摘要： A neural network circuit including a number n of weight coefficients (W1-Wn) corresponding to a number n of inputs, subtraction circuits for determining the difference between inputs and the weight coefficients in each input terminal, the result thereof being inputted into absolute value circuits, all calculation results of the absolute value circuits corresponding to the inputs and the weight coefficients being inputted into an addition circuit and accumulated, and this accumulation result determining the output value. A threshold value circuit determines the final output value, according to a step function pattern, a polygonal line pattern, or a sigmoid function pattern, depending on the object. In the case in which a neural network circuit is realized by means of digital circuits, the absolute value circuits can include simply EX-OR logic (exclusive OR) gates. Furthermore, in the case in which the input terminals have two input paths and two weight coefficients corresponding to each input path, the neuron circuits form a recognition area having a flexible shape which is controlled by the weight coefficients.
