    Abstract: PROBLEM TO BE SOLVED: To solve the problem that when data transfer is performed through a plurality of serial transmission lines, data transfer efficiency decreases and the number of inter-device wires increase since the data showing data borders is added.SOLUTION: When data transfer is performed through a plurality of serial transmission lines, the data showing data borders is imparted to only the data transmitted through one serial transmission path, and not imparted to the data transmitted through the other serial transmission lines. Consequently, a decrease in data transmission efficiency is suppressed without increasing the number of wires, and desired data transfer can be achieved.

    Abstract: PROBLEM TO BE SOLVED: To provide a noise filter and transmission equipment which are capable of cutting off surely an in-phase component included in a differential signal without making an anti-resonance occur in a frequency to be made to be cut off.SOLUTION: A pair of coils 11 and 12 have one ends 11a and 12a connected in the vicinity of a transmission circuit 4 in a pair of transmission lines 7a and 7b, and other end 11b and 12b connected with each other short-circuited. Then, the pair of coils 11 and 12 are coupled electromagnetically so that a magnetic flux for an in-phase component which is transmitted in the pair of transmission lines 7a and 7b may be cancelled mutually, and a magnetic flux for a reversed phase component which is transmitted in the pair of transmission lines 7a and 7b may be strengthened mutually. Between the pair of coils 11 and 12 and a ground GND, a series circuit 6 which has an inductor 2 and a capacitor 3 which are connected serially is connected. Then, each value of the pair of coils 11 and 12, the inductor 2, and the capacitor 3 is set so that the resonance frequency for the in-phase component may be a target frequency.

    Abstract: 本発明のデータ交換装置は、電源(VDDA)より電力供給を受ける送信器(SA4)、その第一の導線が送信器の固定ポテンシャル点(GNDA)に接続されかつ第二の導線が送信器の可変ポテンシャル点に接続される電気ケーブル(C1)及び受信器(SB4)を含む。 前記受信器(SB4)は、ケーブル(C1)内の電流の方向に対抗する電圧の閾値を定めるコンポーネント(DZB4)を含む。 この装置は、その生産が単純で低コストであるように実現される。 装置は、複数の送信器と受信器を相互接続することを可能にし、電圧及び寄生電流に関して感度が低い。
