IPC: G08B17/06
Filed: 1990-06-02
Abstract: PURPOSE:To obtain sensors which are easily constructed while the watching area of one sensor is variable and large by installing >=2 electric conductors on the ceiling, etc., of a watch object space, and using a sense line for at least one of them, and utilizing the sense line as a communication line together with the other electric conductor. CONSTITUTION:A linear temperature sensing element (sense line) 2 which varies in electric resistance according to temperature variation is distributed on the ceiling, etc., of the watch object space and divided at plural parts. Then respective parts of the divided sense line 2 are connected in series through proper relays, information on each part is sent in order to a sensor main body 1 through the sense line 2, and a calculating circuit calculates the temperature of each part of the sense line 2 from the contents to decide whether a fire breaks out or not. Consequently, the electric conductor itself is used as the sense line 2 and the electric conductor can be omitted, which is advantageous to the construction; and the wide watch object area can be covered by one fire sensor 1, so the system is economical.

Filed: 1986-06-24
Abstract: PURPOSE:To enhance the accuracy of the title apparatus to inhibit nonuniformity of rotation at low speed and variation in torque in the case of servo lock, by switching the gain of current amplifier depending on the speed. CONSTITUTION:When the rotation of a motor 5 is low in speed, the phase lag influence of a current amplifier 14 becomes nearly so effective that a 'H' signal is outputted from a microcomputer 17 to the gate of an analog switch 16 through an I/O port 18. Thus the analog switch 16 is opened and the current amplifier 14 becomes a proportional integral amplifier whose gain is fully raised, i.e., the upper limit resistance value is reached. When the number of revolutions of the motor 5 is of high speed, the analog switch 16 is closed and the current amplifier 14 becomes of a proportional type, so that no lag elements of the current amplifier 14 at high speed can be found.
