Latest Patents

Kobayashi's latest patents include an inkjet head driving method and an inkjet recording apparatus. This invention involves applying a voltage signal with a combined drive waveform to a pressure generator, enabling nozzles to jet ink droplets effectively. The method ensures that droplets land on a medium as a single droplet, enhancing the quality of inkjet printing. Each unit drive waveform consists of a first pulse waveform for jetting a droplet and a second pulse waveform for retracting the jetted droplet. The design includes an expansion part for increasing the pressure chamber and a contraction part for reducing it. Notably, the voltage amplitude of the contraction part in the second pulse waveform is greater than that in the first, optimizing performance.
