摘要： Detecting elements of external force consisting of two actuators having magnetic poles at either one or both end surfaces of the actuators located in opposite. The two actuators have opposite electric contacts at the end surfaces and are pivotally connected to each other through a toggle joint of an electric insulating material. External force exerted on the actuators causes the actuators to move and connect or disconnect the contacts in the actuators. The detecting elements can detect the external force applied to the actuators by connection or disconnection of these electric contacts.

摘要： A system for the supervision of normal or abnormal condition of rooms or parts of a house or a building, elevators, water supply and drainage equipments and motors, or the presence or absence of persons in the rooms. Information derived from each room or compartment is applied to each gate of an input gate group provided in a signal transmission device. The output signal of each gate is generated by scanning said input gate group and is detected in a discriminator circuit to determine whether it is normal or not. A normal signal is forwarded to a signal receiving device without modifying the pulse duration of a pulse generated from a pulse generator in the signal transmission device. For an abnormal signal, the duration of a pulse generated by the pulse generator is increased. The signal delivered to the signal receiving device from the signal transmission device is again discriminated in a discriminator circuit to determine whether it is normal or not. The output obtained is indicated on an indicator provided to respond to an information receiving means in the signal transmission device indicating whether the signal either normal or not according to the order of scanning by the signal transmission device.

摘要： This invention relates to a power source setup device for alarm means in a room or a building comprising a main door and secondary doors or windows, said main door and secondary doors or windows respectively having door switches, said main door including a fixing board attached to poles and walls of said door and a locking mechanism having a lock member fixed to said door and engageable by key to a hole on said fixing board, a lock switch on said fixing board to set ON or OFF a power source for all circuits of the alarm means, wherein said lock member moves into or from the hole of the fixing board and thereby the lock switch is operated, and a breaking conductor is incorporated at a location on the outdoor side of the main door and in front of a lock switch to set up a power source, said breaking conductor being adapted to break by external force so as to prevent the alarm means from being destroyed by intruder and to issue an alarm signal.
