    • There is provided a double-sided sliding thrust bearing of a plate shape adapted to be in sliding contact with a counterpart on each of both faces of the thrust bearing, comprising a bearing structure provided with a plate-shaped base member having an anchor effect on each of both faces thereof, and a sliding layer having a thickness not less than 30 μm on each of the faces of said base member which sliding layer is made of a thermosetting resin-containing material. By making the thickness of the sliding layer 10 not less than 30 μm, it becomes possible for the thrust bearing 1 to slide shoes for a longer time even when being used in a dry state and the sliding layer 10 comes to be hardly peeled off from the base member 2 because of the anchor effect of the base member 2. Further, the mechanical strength and thermal conductivity of the thrust bearing 1 can be improved by the base member 2 located between the sliding layers 10.
    • 提供了一种板形的双面滑动推力轴承,其适于与推力轴承的两个表面中的每一个上的对应部件滑动接触,该轴承结构设置有具有锚定效应的板状基座部件 并且在所述基材的每个表面上具有不小于30μm的厚度的滑动层,该滑动层由含热固性树脂的材料制成。 通过使滑动层10的厚度不小于30μm,即使在干燥状态下使用时,推力轴承1也能够滑动鞋子较长时间,并且滑动层10几乎不会从 基部构件2由于基部构件2的锚固效应而产生。 此外,推力轴承1的机械强度和导热性可以通过位于滑动层10之间的基部构件2来改善。

    • A multiplex security system provides two-way data communications between a local panel and multiple microprocessor-based remote panels interconnected over a common data transmission line. A second line provides two-way voice communications between the local and remote panels with automatic forwarding by an audio/data control selector to a central control unit via a single telephone line. Two additional lines provide a common ground and transmit DC power from the local to the remote panels. The remote panels include bus drivers connected to the communications line for transmitting both ASCII digital data messages and a higher voltage request or SRQ signal to the local panel when the remote panel has a message to transmit. The local panel includes two separate receivers for distinguishing the request signal from digital data and a bus driver for transmitting data. The local panel transmits a grant message which is superimposed over the request signal, reducing its voltage level to zero. The remote panel has a receiver for receiving ASCII data from the local panel and for sensing the reduced voltage level to turn off the request signal. The remote panels are assigned priorities by setting different switch numbers in each panel. The switch numbers correspond to unique brief time slots in which each of the remote panels can commence transmitting. Following a grant command, the remote panels count time slots. None can respond until the count equals its respective switch number, and then only if another panel has not already commenced transmitting.
    • 多路复用安全系统在本地面板和通过公共数据传输线互连的多个基于微处理器的远程面板之间提供双向数据通信。 第二行提供本地和远程面板之间的双向语音通信,通过音频/数据控制选择器通过单个电话线自动转发到中央控制单元。 两条额外的线路提供公共地面,并从本地到远程面板传输直流电源。 远程面板包括连接到通信线的总线驱动器,用于当远程面板具有要发送的消息时,将ASCII数字数据消息和较高电压请求或SRQ信号发送到本地面板。 本地面板包括用于区分请求信号和数字数据的两个单独接收器和用于发送数据的总线驱动器。 本地面板发送叠加在请求信号上的授权消息,将其电压电平降低到零。 远程面板具有用于从本地面板接收ASCII数据的接收器,并用于感测降低的电压电平以关闭请求信号。 通过在每个面板中设置不同的开关编号来为远程面板分配优先级。 开关编号对应于其中每个远程面板可以开始发送的独特的短时隙。 按照授权命令,远程面板会计时。 无法响应,直到计数等于其各自的开关号,然后只有当另一个面板尚未开始发送时。
