Patent number: 10837978Abstract: The present invention provides a method for removing liquid from the interior of a flow channel tip, which enables both to reduce the amount of liquid remaining and prevent the time spent removing the liquid from being longer than necessary. The method comprises: suctioning a liquid within a flow channel, the liquid being suctioned into the interior of a liquid suction implement inserted into a first through-hole of a flow channel tip; and removing the liquid within the flow channel. This method comprises: a first suction step for suctioning some of the liquid within the flow channel at a first suction speed; and a second suction step for suctioning the liquid remaining within the flow channel at a second suction speed that is less than the first suction speed, the second suction step being performed in continuation from the first suction step.Type: GrantFiled: November 2, 2016Date of Patent: November 17, 2020Assignee: Konica Minolta, Inc.Inventors: Atsuo Iwashita, Youichi Aoki, Koji Miyazaki

Patent number: 10836986Abstract: A bioreactor system (1A; 1B) includes a variable volume container (3) having a flexible outer wall (27, 29) defining a cell-culture chamber for containing a fluid culture medium, and anchorage dependent cells in suspension. A agitator unit of the system (1A; 1B) is in fluid communication with first, second and third fluid ports (43, 45, 47A; 47B) for performing controlled replenishment of the culture medium in the cell-culture chamber, to admit fresh nutritive culture medium into the cell-culture chamber and for allowing draining of waste culture medium from the cell-culture chamber. The agitator unit further has a roller (15) for pinching the outer wall of the variable volume container (3) to thereby increase its a volume that forms the cell-culture chamber, starting from the initial minimum volume area (23), and means for gently agitating the cell-culture chamber.Type: GrantFiled: July 18, 2014Date of Patent: November 17, 2020Assignee: SCINUS CELL EXPANSION B.V.Inventors: Emerentius Gerardus Roosloot, Rudolf Hendrikus Jozef Das, Joost Dick De Bruijn, Pieter Theo Elias Van Santen

Patent number: 10821736Abstract: A liquid discharge head includes a discharge port; a flow passage; a discharge port part; a supply flow passage; and a recovery flow passage. The flow passage, the supply flow passage, and the recovery flow passage are configured such that the liquid inside the flow passage is capable of being circulated between the inside of the flow passage and the outside of the flow passage. An opening of the discharge port is configured such that a liquid surface of the liquid within the opening of the discharge port has a first region and that a second region, and a viscosity of the liquid in the first region is 1.2 or more times higher than a viscosity of the liquid in the second region.Type: GrantFiled: October 1, 2019Date of Patent: November 3, 2020Assignee: Canon Kabushiki KaishaInventors: Shingo Okushima, Yoshiyuki Nakagawa, Kazuhiro Yamada, Yasuhiko Osaki, Naozumi Nabeshima

Patent number: 10814634Abstract: A capping station is configured for storing a printhead during printer inactivity to preserve the operational status of the nozzles in the printhead. Each capping station has a housing having at least one wall and a floor configured to enclose a volume partially, and a plate having a textured surface that is positioned at a predetermined distance from a top surface of the at least one wall of the housing. The textured surface is made of a resilient material that has cells that contain flushing fluid. A printhead is pushed within the volume of the housing to engage the textured surface of the plate to press the flushing fluid into the faceplate of the printhead. The flushing fluid and the proximity of the textured surface keep ink on the faceplate and within the nozzles of the faceplate from drying.Type: GrantFiled: July 11, 2019Date of Patent: October 27, 2020Assignee: Xerox CorporationInventors: Robert E.
