Title: Preparation of one side surface electroplated steel plate
Inventor: SAKOTA AKITO
IPC: C25D5/02
Filed: 1982-06-14
Abstract: PURPOSE:To certainly prevent the corrosion of a non-plating surface during plating, in carrying out one side surface electroplating, by passing a minute current through the non-plating surface. CONSTITUTION:In carrying out electroplating with respect to one side surface of a steel plate, the potential of a non-plating surface is kept more base than the corrosion potential of the steel plate. That is, when a cathode current is passed through the non-plating surface, an electron is supplied to the non-plating surface. This electron is consumed by the reducing action of Fe<3+> and H<+> and, with the consumption of the electron, said non-plating surface is brought to a state not receiving the electron accompanying the dissolving process of Fe and the elution reaction of Fe is reduced. By this mechanism, the corrosion of the non-plating surface can be prevented.

Filed: 1978-08-23
Abstract: PURPOSE: To enable an element to self-prevent from breakage by arranging No. 2 auxiliary SCR, which is the easiest to be triggered at dv/dr, in parallel with an auxiliary SCR adjoining a control gate electrode.  
     CONSTITUTION: In a ring-shaped auxiliary gate electrode 5, there are a main SCR and No. 1 auxiliary SCR having an nE layer 7 surrounding a gate electrode 4, and the layer 7 is connected to the electrode 5. A disc-like nE layer 8, composing No. 2 auxiliary SCR together with layers pE, nB and pB, is connected to an electrode 5. Thus No. 2 auxiliary SCR is arranged between anode 2 and auxiliary gate electrode 5. As the No. 2 auxiliary SCR's dv/dt bearing value can be freely adjusted by radius R of the layer 8 and can be set to a value lower than those of other parts of an element, and also as the No. 2 auxiliary SCR's geometrical shape does not affect other characteristics, freedom of setting is large. In this mechanism, even if triggering were to be done by quick rising voltage, an element is never damaged.
