    • A differential conversion circuit for converting an unbalanced signal to a balanced signal is provided. The differential conversion circuit is arranged with primarily passive components, and so avoids introducing noise or other disturbances to the signal. The differential conversion circuit has a terminal input for receiving an unbalanced signal that is related to a communication input signal. An inductor and a resonating capacitor connect to the terminal input, and a coupling capacitor connects to the inductor. One differential output line is provided by the resonating capacitor, while the other differential output line is provided by the coupling capacitor. The output from the capacitors is thereby a pair of lines that provide a balanced differential signal which is deliverable to a balanced load.
    • 提供了用于将不平衡信号转换为平衡信号的差分转换电路。 差分转换电路主要配置为无源元件,因此避免了对信号引入噪声或其他干扰。 差分转换电路具有用于接收与通信输入信号相关的不平衡信号的终端输入。 电感和谐振电容连接到端子输入,耦合电容连接到电感。 一个差分输出线由谐振电容器提供,而另一个差分输出线由耦合电容器提供。 因此,来自电容器的输出是一对线路,其提供可平衡负载的平衡差分信号。

    • A messaging system, and method of operation thereof, which supports combinations of directory and mailing list addressing mechanisms. Intended message recipients are specified as declarative addresses, which may include combinations of directory and mailing list information. The messaging system includes a messaging server and an address resolution module. The messaging server receives a message from a sender system and transmits the message to the recipient system. The address resolution module, which is coupled to the messaging server, receives a declarative address associated with the message, resolves the declarative address into at least one messaging address and transmits the at least one messaging address to the messaging server. In one embodiment, a database system may be coupled to the address resolution module to allow address resolution based on information stored in a database. The address resolution module generates a database query based on the declarative address and transmits the generated query to a database system. The database system receives a database query, retrieves at least one messaging address specified by the query and transmits the retrieved at least one messaging address to the address resolution module.
    • 消息系统及其操作方法,其支持目录和邮件列表寻址机制的组合。 预期的消息收件人被指定为声明性地址,其可以包括目录和邮件列表信息的组合。 消息系统包括消息收发服务器和地址解析模块。 消息收发服务器从发送者系统接收消息并将消息发送到接收方系统。 耦合到消息收发服务器的地址解析模块接收与该消息相关联的声明性地址,将该声明性地址解析为至少一个消息传送地址,并将该至少一个消息传送地址发送到消息收发服务器。 在一个实施例中,数据库系统可以耦合到地址解析模块,以基于存储在数据库中的信息来允许地址解析。 地址解析模块基于声明性地址生成数据库查询,并将生成的查询发送到数据库系统。 数据库系统接收数据库查询,检索由查询指定的至少一个消息传送地址,并将检索到的至少一个消息传送地址发送到地址解析模块。

    • A message storage system, for use with a communication network and in which a network presence is provided for an entity, stores a message from a sender to a network presence. The message storage system accepts a query including a specified property, and generates a mailbox including the stored message when one of the message properties is the specified property. A software agent processes the stored message in accordance with a processing preference included in attributes associated with the entity. The message storage system generates a summary of the message and updates the summary of the message in response to modifications to the message.
    • 与通信网络一起使用并且其中为实体提供网络存在的消息存储系统将来自发送者的消息存储到网络存在。 消息存储系统接受包括指定属性的查询,并且当其中一个消息属性是指定属性时,生成包含存储消息的邮箱。 软件代理根据与实体相关联的属性中包括的处理偏好来处理所存储的消息。 消息存储系统生成消息的摘要,并根据消息的修改来更新消息的摘要。

    • A multi-functional epoxy resin with good high temperature properties allowing prolonged service at temperatures above 120.degree. C. is derived from a precursor of formula (I): ##STR1## in which R.sup.3 to R.sup.8 inclusive are independently selected from hydrogen, C.sub.1 to C.sub.3 alkyl or halo-alkyl and R.sup.9 is hydrogen, alkyl or halogen, and in which n has the value 0, 1 or 2. The precursor (I) may be self-coupled or cross-coupled with precursors of other epoxy compounds of the TGDDM type. Such cross-coupling gives rise to a complex mixture containing not only the mixed product, but also the self-coupled products of each constituent. Regardless of the precise chemical make-up of the mixture, the observed glass transition temperature is higher than for TGDDM resins formed without precursor (I). If the substituent at the R.sup.9 position is alkyl or halogen, oligomer formation is suppressed and a less complex mixture results.
