Abstract: A control circuit for adjusting a backlight color is provided. In accordance with a preferred embodiment, the control circuit comprises an input device, a control unit, a backlight, and a plurality of pulse-width modulation units. The input device receives a plurality of external messages to generate a corresponding plurality of control signals. The control unit has a plurality of pins, implements a plurality of calculations based on the plurality of control signals, and generates a plurality of light-adjusting signals, each of which has a respective pulse width. The backlight has a plurality of light sources for a color mixing. Each of the pulse-width modulation units is correspondingly coupled to each of the pins and to each of the light sources, and adjusts a light of the each light source based on the respective pulse width.

Abstract: An activating flux for welding stainless steel includes: from 25 to 40 weight percent of titanium dioxide (TiO2); from 25 to 30 weight percent of chromium oxide (Cr2O3); from 10 to 30 weight percent of silicon dioxide (SiO2); from 10 to 15 weight percent of molybdenum disulphide (MoS2); and from 5 to 15 weight percent of molybdenum trioxide (MoO3), which are active additive materials. A welding rod or wire includes a welding material and an activating flux. The activating flux layer is provided on or in the welding rod or wire and is formed as an outer layer or a core portion of the welding rod or wire.
