    • First sensors measure physical quantities correlated with the heat release value of a fire source, and second sensors measure physical quantities correlated with the amount of the product of burning. At least a pair of one first sensor and one second sensor are arranged in a zone to be monitored. A first threshold of high sensitivity and a second threshold of low sensitivity are set at the first sensors. A third threshold is set at the second sensors. A pre-alarm is given only when the level of signals from the second sensors exceeds the third threshold. A fire alarm is given when the level of the signals from the second sensors exceeds the third threshold and when the level of signals from the first sensors exceeds the first threshold. The outputs from a plurality of such sensors detecting different objects, such as heat and smoke, are processed in the manner in which these outputs are combined together to reliably detect fires and to give a fire alarm. It is possible to improve the accuracy of detecting fires, and to reduce the incidence of false alarms.
    • 第一传感器测量与火源的热释放值相关的物理量,第二传感器测量与燃烧产物量相关的物理量。 至少一对一个第一传感器和一个第二传感器布置在要监视的区域中。 在第一传感器处设置高灵敏度的第一阈值和低灵敏度的第二阈值。 在第二传感器处设置第三阈值。 仅当来自第二传感器的信号的电平超过第三阈值时才给出预报警。 当来自第二传感器的信号的电平超过第三阈值并且来自第一传感器的信号的电平超过第一阈值时,给出火警。 来自检测不同对象(例如热和烟)的多个这种传感器的输出以这些输出组合在一起的方式进行处理,以可靠地检测火灾并发出火警。 可以提高火灾检测的准确性,减少误报的发生率。

    • The present invention relates to a construction of a control switch for use in measuring instruments of various types, such as digital indication type slide calipers. A link member is pivotally supported and pivoting thereof is effected by a movement of a control button. The link member is interposed between a switch portion for effecting the electrical connection or disconnection and the control button, which control button is provided in a side wall of a case body disposed for movement in a direction perpendicular to the working direction of the switch portion, and, when the link member is pivoted by movement of the control button, the electrical connection or disconnection can be effected.
    • 本发明涉及一种用于各种类型的仪器的控制开关的结构,例如数字指示型滑动卡钳。 连杆构件被枢转地支撑,并且通过控制按钮的移动来实现枢转。 连接构件插入在用于实现电连接或断开的开关部分和控制按钮之间,该控制按钮设置在壳体的侧壁中,该壳体设置成沿与开关部分的工作方向垂直的方向移动, 并且当通过控制按钮的移动枢转连杆构件时,可以实现电连接或断开。
