Patent number: 7344234Abstract: A fluid container, such as, for example, an inkjet print head cartridge, architecture uses a relatively large filter that is located below a negative pressure material chamber and a free ink chamber in a side-by-side relationship. The negative pressure material volume relative to a free ink chamber value can me made to be approximately one to one. Both chambers overlie an ink manifold/delivery port and are separated from the delivery port by a filter. Flow impedance of the cartridge is reduced, as a result, in any orientation of the cartridge. The filter may be separated from, or in contact with a negative pressure material. A cartridge lid is provided with a negative pressure material chamber which is suspended into the cartridge. A negative pressure material having a fiber felt construction is provided.Type: GrantFiled: January 21, 2004Date of Patent: March 18, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Eric A Merz, Brian S Hilton, Kazuyuki Oda, Takatoshi Tsuchiya

Patent number: 7294223Abstract: A method for joining fluid containers and fluid ejectors in a fluid ejecting device are provided. The fluid container includes one or more heat stakes and a substrate includes one or more apertures for receiving the heat stakes and one or more three-dimensional features in the vicinity of the one or more apertures. The fluid ejector and optionally an elastic member are interposed between the fluid container and the substrate. Thermal energy is applied to the one or more heat stakes so that the one or more heat stakes soften to occupy the apertures and three-dimensional features of the substrate and pressure is applied to maintain contact between the fluid container, elastic member, fluid ejector and substrate. The present invention is also directed to substrate including one or more apertures for receiving heat stakes and one or more three-dimensional features in the vicinity of the one or more apertures.Type: GrantFiled: January 29, 2004Date of Patent: November 13, 2007Assignee: Fuji Xerox Co., Ltd.Inventors: Brian S. Hilton, Eric A. Merz, Takatoshi Tsuchiya, Hiroki Murakami

Patent number: 7172272Abstract: A fluid ejection container system provides a first container that contains the fluid, the first container being evacuated to negative gauge pressure when being filled with the fluid, a second container having a capillary medium that contains the fluid, a passage between the first and second containers communicating the fluid at a level wherein the passage is wetted with the fluid, a ventilation port to communicate air between an interior region in the fluid ejection system and ambient, at least one spill over region to communicate the fluid with the second container, and a plurality of channels to communicate at least the air between the interior region and the second container; wherein the at least one spill over region has sufficient volume to contain a quantity of the fluid that migrates out of the second container. The fluid ejection container system also provides a lid for sealing the first and second containers from the ambient, wherein the channels are disposed on the lid.Type: GrantFiled: November 26, 2003Date of Patent: February 6, 2007Assignee: Fuji Xerox Co., Ltd.Inventors: Takatoshi Tsuchiya, Eric A. Merz, Kazuyuki Oda, Brian S. Hilton

Patent number: 6588874Abstract: An airtight elastic cap of an ink-jet recording head and a storage container employing the airtight elastic cap provide high airtightness between a nozzle face and the airtight cap and minimizes ink leak from the recording head even when the head is mounted or dismounted, or when a storage environment changes suddenly. The airtight elastic cap includes a body and an inside wall provided inside thereof. A portion of the wall defines a first space and another portion defines a second space positioned continuously to a center of the first space. The storage container includes a container body that houses the ink-jet recording head and the airtight elastic cap, placed within the container body, that abuts against and protects an ink emission face of the ink-jet recording head while the ink-jet recording is housed.Type: GrantFiled: July 23, 2001Date of Patent: July 8, 2003Assignee: Fuji Xerox Co., Ltd.Inventors: Takatoshi Tsuchiya, Atsumichi Imazeki, Harumi Tamura
