A group of novel power conversion concept is developed with this invention for LED and OLED drive applications. Strain states at respective points on the press-formed sheet material are plotted on a forming limit diagram including the forming limit curve of a sheet material to produce a strain distribution chart. In the first step the charged particles are pushed into an upper substrate well below the floating gate but not allowed into a deeper well of opposite conductivity type relative to the upper well. The component handling device is removably coupled to the carrier device. The accessory is provided in the form of a combination of a couple of meshed tube bodies formed by weaving metal wire to have respective different mesh density, wherein a dual-structure meshed tube body 3 is composed of a metal meshed tube body 1 with coarse mesh density positioned outwardly and a metal meshed tube body 2 with fine mesh density positioned inwardly. The stage comprises a matching network that separates amplified signals of interest received from an amplifier from amplified unwanted signals received from the amplifier in conjunction with additional downstream filters.
