摘要： PURPOSE:To detect the position of a moving body surely at the boundary part of addresses as well by arranging plural crossing pairs by shifting their crossing parts in such a manner that they do not cross simultaneously at the same position. CONSTITUTION:Multipair parallel lines 10 used for a system for detecting the position of moving bodies consist of a transmission pair 12 serving also as a reference pair and 1st-n-th pairs of plural crossing pairs 141, 142...14n. The transmission pair 12 is connected to a transmitter 18 via a transformer 16, and the plural crossing pairs 141, 142...14n are connected to the output terminals via transformers 201, 202... 20n and resistances 221, 222...22n, respectively. The output terminals thereof are connected to a discriminating circuit. The crossing parts 151, 152...15n are so arranged by being shifted in such a manner than the plural crossing pairs 141, 142... 14n do not cross simultaneously in the same place.

摘要： PURPOSE:To attain contactless signal transmission and to detect a rotary angle, by providing an antenna to a fixed and a rotary section and bringing close to each other them so as to be subjected to electromagnetic induction mutually, in a device transmitting and receiving signals between the fixed and the rotary section. CONSTITUTION:In applying a signal frequency-modulated to the antenna 16 of the rotary section 12 with a modulator 20, signal voltages V1, V2 in response to the rotary angles of the rotary section 12 are respectively induced in two induction coils 18A, 18B of the antenna 18 of the fixed section 14. The signal voltages V1, V2 are respectively processed and synthesized at the 1st and the 2nd adding circuits 26A, 26B. The phase of synthesized outputs Va, Vb is compared at a phase comparator 28, to detect the rotary angle of the section 12 to the section 14. Since the synthesized output Vb is not made to zero, it is demodulated at a demodulator 30, the signal from the rotary section 12 is received and the information is transmitted.

摘要： PURPOSE:To constantly enable detection of the position of the moving body by mounting a plurality of resonant circuits having different resonant frequency in different positions in relation to the moving direction on the moving body and by arranging the same so that they are not present concurrently on the crossing point of a plurality of observing couples. CONSTITUTION:Two resonant circuits 2A and 2B whose resonant frequencies are fA and fB are mounted in the moving direction at a distance from each other on the moving body 1. When a transmission signal of frequency fA is transmitted from a transmitter 5 to a transmitting couple 4 fixed along the moving path of the moving body 1, the resonant circuit 2A resonates and a voltage VrA delayed in phase at 90 deg. from the voltage VoA of the transmitting couple is induced in the resonant circuit 2A, whereby a voltage delayed in position at 90 deg. from VrA is induced in a reference couple 60 and in each of observing couples 61-6n. Since the resonant circuit 2A stops at the crossing point of each of observing couples 62-6n, it can not be compared in phase with the reference couple 60 and consequently, detection of the position thereof can not be conducted. However, when the resonant circuit 2B is made to resonate by a transmission signal of frequency fB, the detection of the position is conducted, since the resonance circuit 2B is not present at the crossing point. Accordingly, the position of the moving body 1 can constantly be detected.

摘要： PURPOSE:To enable remote operation with less number of lines, for the devices to be controlled and arranged in many numbers, by arranging crossing lines in whose crossing intervals are taken as the interval of devices to be controlled and the different interval of their multiple, and coupling current sensing elements every minimum section. CONSTITUTION:A plurality of pairs of crossing lines 121-123 are provided to devices located at a plurality of positions. In the crossing interval of the crossing lines, the line 123 is the interval of devices to be controlled, the line 122 crosses with double intervals, and the line 121 is a parallel line without the crossing. Current sensing elements 141-144 are located on one line of crossing lines every minimum crossing section of the crossing lines. Further, these current sensing elements are coupled so that they can be operated when the current value on one line of the crossing line reaches the same prescribed value. By the remote operation of the devices with this current sensing element, the devices having 2 addresses can be operated with the n+1 pairs of crossing lines.

摘要： PURPOSE:To make the communication between a mobile station and a fixed station and between fixed stations possible, by a common inductive communication line. CONSTITUTION:The first fixed station 2 and the second fixed station 3 are connected to both ends of an inductive radio line 1. These fixed stations are provided with band pass filters 41-44 which permit frequencies f1-f4 to pass through. In case of the communication between the fixed station 2 and a mobile station 6, when the frequency f1 is transmitted from the fixed station, it is received by an antenna 71 of the mobile station; and when the frequency f2 is transmitted from an antenna 72 by the mobile station, the output of the frequency f2 is obtained by the band pass filter 42 in the fixed station. In case of the communication between fixed stations 2 and 3, when the frequency f3 is transmitted from the fixed station 2, the output is obtained from the band pass filter 43 in the fixed station 3, and when the frequency f4 is transmitted from the fixed station 3, the output is obtained from the band pass filter 44 in the fixed station 2.

摘要： PURPOSE:To cancel impossibility of position detection due to a frequency shift between a transmission signal and a resonance circuit, by the scanning of a given width by taking the resonance frequency of the resonance circuit to the center for transmission signal frequency. CONSTITUTION:A resonance circuit 2 is mounted on a mobile body 1 and a transmission pair 3 is fixed along the moving path of the body 1 to excite this resonance circuit at the fixed side. Transmission signal is fed to the transmission pair 3 from an oscillator 4. Further, at the fixed side, a plurality of observation pairs 51-5n consisting of crossing pairs different in the cross pitch are provided. Thus, in the position detection of a mobile body, if the transmission signal frequency and the resonance frequency are shifted due to temperature change, sometimes no detection of position is possible. Thus, the transmission signal frequency is scanned by + or -DELTAf by taking the resonance frequency f0 to the center. With the constitution like this, even if the resonant frequency is shifted, when it is within the frequency range of f0+ or -DELTAf, the resonance is made to detect the position.
