    • The key button telephone system comprises a key service unit and a plurality of key telephone units. The key service unit and each key telephone unit are interconnected by a pair of cables, one of which is used as a talking circuit and the other is used to transmit and receive information signals and operating power. The key service unit comprises a line circuit for supervising the state of a line, a station unit for supervising the line circuit, and for supplying to the key telephone unit an information signal representing the state of the line and the operating power, a switching network controlled by the control output from the station unit for connecting the key telephone unit to the line, and a common control circuit for controlling the line circuit and the station unit. Each key telephone unit comprises a telephone circuit connected to the switching network, a telephone control circuit for supervising the state of the key telephone unit connected to the station unit, and a DC converter for converting a DC voltage supplied from the station unit into a predetermined DC voltage.
    • 键按钮电话系统包括密钥服务单元和多个密钥电话单元。 密钥服务单元和每个密钥电话单元通过一对电缆互连,其中一个电缆用作通话电路,另一个用于发送和接收信息信号和操作电源。 密钥服务单元包括用于监视线路状态的线路电路,用于监视线路电路的站单元,以及向密钥电话单元提供表示线路状态和操作功率的信息信号,切换网络 由站单元的控制输出控制,用于将密钥电话单元连接到线路,以及用于控制线路电路和站单元的公共控制电路。 每个密钥电话单元包括连接到交换网络的电话电路,用于监控连接到站单元的密钥电话单元的状态的电话控制电路,以及用于将从站单元提供的直流电压转换为预定的 直流电压。

    • Since the disinfectant solution bottle has a detachable section and a sealing section, the disinfectant solution bottle can be connected to the inlet of the disinfectant solution tank of the cleaning and disinfecting unit in a watertight manner; the mouth section of the bottle is closed with the sealing section before the disinfectant solution bottle is attached to the inlet of the disinfectant solution tank; and while the disinfectant solution is being connected to the inlet of the disinfectant solution tank, the disinfectant solution or concentrated disinfectant solution in the disinfectant solution bottle can flow into the disinfectant solution tank via the inlet because the inside of the disinfectant solution bottle and the inside of the disinfectant solution tank can communicate with each other in a watertight manner cut off from the outside, for example, due to automatic rupture of the sealing section when the disinfectant bottle is attached to the inlet of the disinfectant solution tank.
    • 由于消毒剂溶液瓶具有可拆卸部分和密封部分,消毒剂溶液瓶可以以水密的方式连接到清洁和消毒单元的消毒剂溶液罐的入口; 在消毒剂溶液瓶附着到消毒剂溶液罐的入口之前,瓶子的口部封闭有密封部分; 消毒剂溶液与消毒液槽的入口连接时,消毒液溶液瓶中的消毒液或浓缩消毒液可以通过入口流入消毒液溶液罐,因为消毒液溶液瓶内部 的消毒剂溶液罐能够以从外部切断的防水方式彼此连通,例如,当消毒剂瓶附接到消毒剂溶液罐的入口时,由于密封部的自动破裂。
