Light bulbs, containing both electrodes decline in protecting ring. Effectively reducingelectrode sputtering, reduce blackheads, prolong lamp life.
灯管光衰小，两端电极装有内保护环。有效减少电极溅射，减少黑头，延长灯管寿命。

Enhancing electrical erosion resistance of tool electrode and reducingelectrode wear is one of research keys to fabricate HARMs with micro EDM technology reliably, stably and efficiently.
Trimmable chip capacitors are build up as multilayer plate capacitors. Vaporizing the top layer with a laser decreases the capacitance by reducing the area of the top electrode.
