摘要： PURPOSE: To obtain a high accuracy position measuring result by removing dispersion from data necessary for position measurement of A/C code to which dispersion is previously given in the position measurement utilizing the A/C code of a GPS satellite. CONSTITUTION: The A/C code of a GPS satellite 1 is received with a GPS receiver 4 in a specified position to measure the specified position. A control point position measuring unit 2 which sends the position measuring data in the specified position and data of the utilizing satellite with a transmitter 7 and an optional point position measuring unit 3 which receives the C/A code of the GPS satellite 1 with a receiver 14 in an optional position to measure the optional position and receives the position measuring data in a specified position and data of the utilizing satellite with a receiver 17 are arranged. The optional point position measuring unit 3 calculates relative position information between the specified position and the optional position from the position measuring data in the specified position and position measuring data in the optional position in real time.

摘要： PROBLEM TO BE SOLVED: To reliably control to make inoperative an ignition function of a gun powder charged body by identifying a friend or a foe with a detection of radar waves radiated from an object body. SOLUTION: A control system comprises means 3b for receiving radar waves radiated from an object body which is provided with a radar and a velocity detector 2 which detects a moving velocity of a moving body on which an automatic friend identifying mechanism is mounted. In response to a detected velocity information, an output frequency of a local oscillator 1 and an output code of a code generating circuit 5 are changed so as to detect whether a code of a signal obtained by mixing the received radar waves and the output of the local oscillator 1 synchronizes with an output code of the core generating circuit 5. When they are synchronized with each other, radio waves are radiated toward the radar for a given time which is determined based on the detected velocity information.

摘要： PURPOSE: To remarkably increase an attack range and to improve the mine contact ratio by knowing the position of a target if there is the target in the vicinity even if the target is not disposed directly above the mine, and being capable of attacking the target from above the target. CONSTITUTION: A wide area mine body fuse 1 knows the absolute position of a target by using a radio transmission and reception sensor 6, transmits it to a wide area mine element fuse, which so outputs a signal to a steering unit as to reduce the difference between the position of the element and the position of the target by a navigation sensor, directs the power direction of a nose toward the target when approaching the target, and outputs a fire signal toward the target.

摘要： PROBLEM TO BE SOLVED: To dispense with a searching function of a radio wave sensor and to lessen power consumption by a system wherein signals from nondirectional acoustic sensors are whitened when it is detected that a target sound increases to a predetermined level or above, and directional angles formed by the target sound and the reference coordinate axes are computed from the signals whitened. SOLUTION: A sound generated by a target is detected by an acoustic sensor 1 and given to a computer 13 through an A/D converter 7, while it is given to a comparator 15. When an input signal exceeds a reference voltage, the comparator 15 sends a signal of a command to start computation of the direction of the target to the computer 13. The computer 13 removes low-frequency components from acoustic signals from individual acoustic sensors and takes out high-frequency components therefrom (whitening) and, using the white signal from the acoustic sensor 1 as a reference white signal, executes a processing of mutual correlation between the reference white signal and the white signal of each acoustic sensor. It calculates the direction of the target from mutual time relations and transmits values thus obtained to a computer 12.

摘要： PURPOSE:To enable an omnidirectional tilt angle sensor to detect the tilt angle of the sensor even when the sensor is tilted in any direction by forming the inner surface of a case to a spherical shape and sticking a large number of electrodes to the inner surface while the inside of the case is kept empty or filled up with a nonconductive liquid, and then, installing the tilt angle sensor so that the electrodes can be maintained at horizontal positions. CONSTITUTION:Electrodes 2 and 3 are alternately stuck to the inner surface of a case 1 and a voltage from a power source 5 is applied across the electrodes 2 through wires 4. The electrodes 3 are connected to a signal processing circuit 7 which removes noise caused by the chattering of conductors and detects angles through wires 6. The case 1 can have any external shape, even a square shape, etc., and a spherical conductor 8 is put in the case 1. The central axis 10 of the case 1 is tilted against a vertical axis 9 by a certain angle. Since a large number of concentric ring-like electrodes 2 and 3 are stuck, the tilt angle of this sensor can be detected even when the sensor is tilted in any direction and, when slits are formed in the electrodes, the tilt direction of the sensor can be detected.

摘要： PROBLEM TO BE SOLVED: To control an activating and inactivating device in the service area of a commander with high reliability. SOLUTION: An activating and inactivating device control system consists of the commander (a) and network type activating and inactivating devices b1 to bn and allows the commander (a) to control the activating and inactivating devices b1 to bn by using radio waves. Each of the activating and inactivating devices b1 to bn is equipped with a repeating function. When the radio wave propagation path between the commander (a) and a specific activating and inactivating device is incommunicable, one or two frequencies are used by other activating and inactivating devices for repeating to establish a communication between the commander (a) and specific activating and inactivating device.

摘要： PURPOSE: To prevent secret information from being leaked to the third person by instantaneously breaking or erasing the program or data held in an IC board at the time of the change of the distance or the shape of a conductive member to detect the action of the third person who tries to acquire the secret information. CONSTITUTION: An IC board 10 has the circuit constituting a sensor 13 which detects the action of the third person who tries to acquire the secret information. The sensor 13 is provided with an LC oscillator using a capacitor C, and the electrostatic capacity of the capacitor C is changed by the change of the distance between a fixed metallic electrode 5 and a mobile aluminium foil 3 or the shape of this foil 3. If the change of the distance or the shape of the aluminium foil 3 is detected by the sensor 13, a secrecy information destruct/erase circuit is operated to instantaneously destruct/erase the contents of the memory, namely, secrecy information (program or data) in a printed board 1.
