Patent number: 8784938Abstract: A functional-film fabricating method includes applying a coating by ejecting droplets of functional liquid from plural nozzles to ejection areas for forming a functional film which are surrounded by bounded areas having a liquid repellent property, during a single scanning. In applying the coating, when there is a non-ejectable nozzle out of plural nozzles to be used for applying a coating to a single ejection area, the amount of droplets of the functional liquid ejected from another ejectable nozzle to be used for applying a coating to this ejection area is larger than that of cases where there is no non-ejectable nozzle.Type: GrantFiled: June 7, 2010Date of Patent: July 22, 2014Assignee: Panasonic CorporationInventors: Naoki Suzuki, Takao Nagumo, Hidehiro Yoshida, Hiroshi Hayata, Masahiro Muro

Patent number: 6080286Abstract: A trigger gas feed system is normally kept opened before a discharge is started. The trigger gas feed system is shut instantaneously, for example, when the discharge is generated, thereby to set a vacuum chamber at a sputtering pressure. The trigger gas feed system is opened again after the discharge is finished. The opened state is continued until another discharge is started. Accordingly, the pressure in the vacuum chamber before the discharge is maintained always constant, and the vacuum chamber is returned to the sputtering pressure in a short time.Type: GrantFiled: August 26, 1997Date of Patent: June 27, 2000Assignee: Matsushita Electric Industrial Co.Inventors: Akira Okuda, Masahide Yokoyama, Hiroshi Hayata
