    • Disclosed are a noise eliminating element having a junction of components of two kinds of electroconductive materials, characterized in that the absolute values of the thermoelectric power of the two kinds of materials is 50 .mu.VK.sup.-1 or higher and there is substantially no rectifying action at the junction. Both the Seebeck effect and the Paltier effect occur simultaneous and create a transient phenomena in one element. Because of the transient phenomena in one element and because of the transient phenomenon based on both effects, noises, particularly the standing wave noises generated at around output current near to zero are eliminated. The noise eliminating elements can be inserted in a magnetic circuit of a speaker circuit for acoustic equipment or in a deflecting coil circuit of an electron image display device.
    • 公开了具有两种导电材料的部件的接合部的噪声消除元件,其特征在于,两种材料的热电功率的绝对值为50μVK-1或更高,并且基本上没有整流作用 交界处。 Seebeck效应和Paltier效应同时发生,并在一个元素中产生瞬态现象。 由于一个元件中的瞬态现象,并且由于基于两种效应的瞬态现象,噪声,特别是在接近零的输出电流附近产生的驻波噪声被消除。 噪声消除元件可以插入用于声学设备的扬声器电路的磁路中或电子图像显示装置的偏转线圈电路中。

    • A “PN junction element ta which produces the Peltier effect and Seebeck effect within the same element and imparts a noise reducing effect,” which prevents an adverse influence of white noise included in an AC waveform to be supplied from a commercially available AC power supply or a parasitic noise or the like caused by electromagnetic interference on an electromagnetic device that is supplied with power and which is effective when attached at the designing or manufacturing stage to each “low-power” functional circuit which provides a later-attached or externally-attached device is adapted to a “high-power” circuit. An external attachment unit is constructed by separating at least one of lines between an AC power input terminal IN and an output terminal OUT to an electromagnetic device into parallel branch lines a and b, and connecting the series circuit of a diode da, db and a PN junction element ta, tb to each branch circuit, thereby facilitating its use by ordinary users.
