[I] An ultimate DC current power source revolution by the ultra electrolytic capacitor Black Gate

---

A roll of the DC current power source in electronic devices

---

The DC current power source for driving the electronic devices usually converts a commercial AC current into a DC current by rectifying and smoothing the AC current, in which an electrolytic capacitor is used for smoothing the rectified AC current. Although it is natural that the power source must be able to afford all the load of the electronic device, it receives all the signal currents returned from the device including noises from inside or outside of the device

Importance of the capacitor for smoothing

---

The electrolytic capacitor generally used is operated based on an ion transfer, with which a signal component is transferred by ions in an electrolytic solution. The electrolytic capacitor thus generates the largest non-linear distortion among other passive components, in which the signal speed and phase are delayed affected by the property of the ion. Moreover, the electrolytic capacitor generally used has irreversibility, in which a conductive property is quite different from each other depending on the direction of the current flow between the electrodes of the capacitor. Thus, the complete performance of the electronic devices has been greatly affected by the large distortions generated by the capacitor due to its irreversibility.

[II] The completely reversible Black Gate has been accomplished first in the world

---

As is already informed, Jelmax Co., Ltd. has invented the transcendent electron transfer Black Gate, in which fine conductive particles are distributed in the separator between the electrodes under a certain conditions and only electrons separated from the ions are transferred in a high speed by suppressing a movement of the ions. The Black Gate is characterized by a completely non-polarized capacitor, which has a cathode electrode having the same structure as the anode electrode. The drawbacks described above are resolved. The characteristics are as follows; Frequency is 10GHz (100 thousand times). A transmitting speed is as fast as an optical fiber. Impedance and E.S.R. characteristic are about 1/10. A phase characteristic is not changed in BS digital frequency band, 70MHz. A noise is -174db (1/1000, which is world record). An operating temperature is -40 ℃〜＋85 ℃. A life is nearly permanent. The Black Gate can be applied to all kinds of electronic devices.

The advantages of the super-E-Caps capacitor provided by a pair of non-polarized Black Gate

The noiseless world never has been realized A device with unlimitedly high performance

The super-E-Caps capacitor is an ultimate mechanism, in which the internal resonance (generated by an inductance of the electrodes and an internal capacitance) indispensable for capacitors is completely eliminated.

[III] Why the internal resonance of the capacitor is harmful　internal resonance

---

Most of engineers can understand that the capacitor, which is manufactured by winding electrode foils, have a resonance phenomenon with an inductance component and an internal capacitance. However, they are unconscious of its harmfulness that may be a cancer of the electronic devices. The capacitor has a resonant point fo varying from 10KHz to a few MHz depending on its capacitance or structure, which can not be avoided by even a capacitor having sheet electrodes. The impedance continues decreasing to the resonant point (a real area) in a nonreflecting and absorbing area and suddenly enters into a reflecting area where the impedance begins increasing (an imaginary area) at the resonant point fo. In this area, the capacitor loses its function, reflecting signals and noises instead of absorbing them giving a heavy damage to the electronic devices. In the reflecting area, pulse noises interfere with each other emitting a lot of harmonic noises in or out of digital circuits using pulse signals. There is no effective measure against the situation. In that situation, for example, a technical standard has to be admitted at ones discretion that noise frequencies are inevitable up to about 20 % of the rectified output voltage. Black Gate has broken through the situation for the first time in the world. That is a revolutionary capacitance, which has succeeded in converting all the frequency areas into the nonreflecting and absorbing area (the real area) by eliminating the internal resonance. See the Technical report No. 96, super-E-Caps capacitor series 11.

[IV] The structure and function of the connecting portions of the super-E-Caps capacitor are important

---

Non-polarized Black Gates are mass-produced by automated fabricating machines, so that the difference in the electrical properties among the products is negligibly small compared with their difference among the capacitances or structures. However, long lead wires are undesirable although they are marked as L and S meaning long and short respectively to distinguish the winding direction of the electrode foils. It is important to connect the lead wires at their root directly to a broad and good conducting connecting board or rod, which does not provide a resistance or inductance, with a solder of good quality. It is also important to arrange the capacitors so that axis of them may lie in parallel with each other and that the magnetic fluxes generated from them may be completely coupled with each other. It is desirable for the leading wire of the connecting board or rod to be a twist wire of a little bit large diameter, one end of which is connected to them at their center portion. A table is attached herewith for showing lengths of the lead wires for those who design the connecting board or rod. Harmonic Distortion Characteristics
