■The Idling Process
 When a Black Gate capacitor mounted on an electronic device is actuated, its electrodes are gradually activated as signal current runs into them, and typical non-linear and phase distortion characteristics decrease a great deal while the power transfer efficiency improves significantly. This“idling process”takes about 30 hours as a standard level to demonstrate to the best of Black Gate ability, and the time required varies according to its capacity, voltage, and signal level.
  Once this process is completed, the effect continues as long as the capacitor is kept at the same place or the operating environment does not experience a change. The effect has been proved with all types of electronic equipment: Analog, digital and high-frequency ones. Please note that the“idling”totally differs from“aging”, which applies a direct current voltage without giving signals(Refer to Jelmax Technical Report No.47 for detail) .
