Patent number: 10293309Abstract: A new method for generating micro-nano bubbles that uses water hammering, a bubble generating nozzle, and an apparatus for generating micro-nano bubbles are provided to construct a system. The system is for generating micro-nano bubbles in a large amount using only pure water, which does not include any nucleating agents, and for performing not only a clean washing and sterilization but also the generation of uncontaminated micro-nano bubbles. The method defined in the present invention uses water hammering power produced by a mutual collision of jets of dissolved-gas-including solution squirted from two or more spouts.Type: GrantFiled: June 13, 2013Date of Patent: May 21, 2019Assignee: SIGMA-TECHNOLOGY INC.Inventors: Yoshiaki Tachibana, Kousuke Tachibana, Kaoru Harada, Souzou Sasajima, Kunihiro Tamahashi, Kyoko Honma, Yuuki Matsumoto

Patent number: 6595629Abstract: Ink particles that start flying toward the printing medium P earlier than or later than the ink particles for the line central area are used as ink particles for the line ends. Accordingly, it is possible to compensate for the affects of electrical charges onto the flying path of the ink particles for the line end portions, reducing the amount of bending at the ends of the printed line such that the bend is not noticeable, thereby improving the quality of printing to satisfy consumer demands.Type: GrantFiled: December 7, 2001Date of Patent: July 22, 2003Assignee: Hitachi Koki Co., Ltd.Inventors: Yoshiaki Tachibana, Takashi Shibaishi
