Patent number: 9352498Abstract: In manufacture of a polyimide film, self-supporting film is heated with both ends in a width direction held and carried by the tenter apparatus. The tenter apparatus has a guide member placed on each side of a carry path for the self-supporting film and a pair of tenter chains each moved along the guide member and each including a film holding mechanism for holding an edge portion of the self-supporting film. The tenter chain has a rotating body supported rotatably around a shaft member extending in a direction in parallel with a carry face of the self-supporting film and perpendicular to a longitudinal direction of the guide member for movably supporting the tenter chain. The shaft member is directly or indirectly fixed to a member identical to a member to which the film holding mechanism is fixed.Type: GrantFiled: October 7, 2010Date of Patent: May 31, 2016Assignee: UBE INDUSTRIES, LTD.Inventors: Hiroyuki Ikeuchi, Yujiro Noda, Yasuhiro Nagoshi, Takeru Fujinaga, Toshihiko Anno, Masakatsu Kimura

Patent number: 6147438Abstract: The present invention provides a piezoelectric film element with improved adhesion between a first protective film and a substrate. This invention also provides a method of manufacturing a piezoelectric film element, which makes it possible to selectively form, by a hydrothermal synthesis, a piezoelectric film with excellent piezoelectric properties in a specified area. This piezoelectric element comprises, over a substrate 12: a piezoelectric film; a common electrode and an individual electrode located to hold the piezoelectric film in between; a first protective film 14 which is formed over almost the entire surface of the substrate 12 and which protects the substrate 12 to avoid the formation of the piezoelectric film directly over the substrate 12; and a base film 16 which is formed over the first protective film 14 in the area for forming the piezoelectric film, and which functions as a base when the piezoelectric film is caused to grow to be formed.Type: GrantFiled: June 22, 1998Date of Patent: November 14, 2000Assignees: Seiko Epson Corporation, Ube Industries, Ltd.Inventors: Tsutomu Nishiwaki, Masami Murai, Kazuo Hashimoto, Toshihiko Anno
