Patent number: 11761474Abstract: A control cable connection structure includes a long, narrow casing, a casing end, a cable end and a slider. An end portion of a first conduit is anchored at one end portion, in a length direction, of the casing. An end portion of a second conduit is anchored at the casing end. The casing end is superposed and assembled with the casing in a radial direction of the second conduit. The cable end is attached to an end portion of a second inner cord. An end portion of a first inner cord is anchored at the slider. The slider is supported at the casing to be slidable in the length direction thereof. In the assembled state, the cable end is engaged with the slider at an opposite side from a side at which the second conduit is disposed, and the second inner cord is connected with the slider.Type: GrantFiled: October 11, 2019Date of Patent: September 19, 2023Assignee: NHK SPRING CO., LTD.Inventors: Yoshihisa Tani, Akihiko Kitazawa, Katsuhiko Kitahara

Patent number: 7125108Abstract: A liquid cartridge is provided that supplies liquid to a liquid ejecting apparatus by being mounted in the liquid ejecting apparatus. The liquid cartridge includes a cartridge body having a side face in which an opening is formed; and a flexible film for forming an ink accommodating chamber that is a closed space for accommodating the liquid, with the cartridge body by covering the opening of the cartridge body. The flexible film is caused to deform toward the ink accommodating chamber by atmospheric pressure that acts on the flexible film when the liquid cartridge is got out from a vacuum bag in which the liquid cartridge is packaged, thereby increasing the pressure in the ink accommodating chamber.Type: GrantFiled: December 10, 2003Date of Patent: October 24, 2006Assignee: Seiko Epson CorporationInventors: Koichi Toba, Satoshi Shinada, Yasuto Sakai, Kenji Ito, Akira Ichihashi, Yuichi Seki, Akihiko Kitazawa, Taku Ishizawa
