A waveform signal output circuit selectively outputs, to an ejection energy applier, either one of a first waveform signal so as to make an ink droplet ejected from a nozzle and a second waveform signal so as not to make an ink droplet ejected from the nozzle. The present technology also concerns a device for execution of an inductive low or high-frequency pressure welding method for joining the metal components, especially components of a gas turbine, with at least one induction generator and at least one inductor, as well as a component produced with the method according to the present technology. The patterned layer of ARC is removed, the remaining patterned hardmask layer is used as a mask for etching the substrate. This invention also encompasses certain non-silicone pre-vulcanized raw rubber formulations made from at least a majority by weight of styrene butadiene rubber that include silver-based components to provide highly desirable long-term antimicrobial characteristics within the ultimate cured rubber articles made therefrom.
