Publication number: 20240132854Abstract: There has been demand for an additional method for producing antibodies. The present invention provides: a polymer-coated crosslinked alginate gel fiber in which a core layer containing a crosslinked alginate gel and either antibody-producing cells (e.g., antibody-producing CHO cells) or bioactive-substance-producing cells (e.g., MIN6 cells derived from pancreatic ? cells) is coated with a cationic polymer; and a method for producing antibodies, a bioactive substance, etc., using the fiber.Type: ApplicationFiled: December 27, 2021Publication date: April 25, 2024Applicant: MOCHIDA PHARMACEUTICAL CO., LTD.Inventors: Shoji FURUSAKO, Naoto TSUDA, Tsutomu SATOH, Tomohiro NARUMI, Shingo SATO

Patent number: 9005529Abstract: A housing having a suction port and a discharge port, an impeller 21 and a casing 22 that houses the impeller 21, an air blower 2 housed in the housing, a filter that lets through the air suctioned from the suction port by the air blower 2, and two ion generating sections that generate positive and negative ions are provided. The ion generating section is arranged on a circular-arc guide wall 2a in the casing 22. The positive and negative ions generated by the ion generating section are efficiently included in the air passing through as laminar flow along the circular-arc guide wall 22a.Type: GrantFiled: March 17, 2009Date of Patent: April 14, 2015Assignee: Sharp Kabushiki KaishaInventors: Tsutomu Tsuda, Ichiro Yoshimura, Hiromu Nishida

Patent number: 8934212Abstract: An ion generating apparatus has: a housing having an intake port and an exhaust port; a fan having an impeller and a casing accommodating the impeller, and accommodated in the housing; a filter passing the air taken in through the intake port by the fan; and two ion generating parts generating positive ions and negative ions. The ion generating parts are arranged in an arc-shaped guide wall of the casing. The positive ions and the negative ions generated by the ion generating parts are efficiently mixed into air flowing in a state of laminar flow along the arc-shaped guide wall.Type: GrantFiled: March 2, 2010Date of Patent: January 13, 2015Assignee: Sharp Kabushiki KaishaInventors: Tsutomu Tsuda, Ichirou Yoshimura

Patent number: 8500106Abstract: A disc-shaped filter unit including a filter main body having a water absorbability and a holder having a non water absorbability is disposed in a vertical orientation, with a part of a circumferential portion thereof immersed in water reserved in a water tank, and is rotated by a rotation drive mechanism in a circumferential direction. The filter unit has an absorptive region and a non-absorptive region arranged adjacent to each other in the circumferential direction. Therefore, in accordance with rotation of the filter unit in the circumferential direction, a state where the absorptive region is immersed and the filter main body of the filter unit absorbs water through a water-conduction hole and a state where the non-absorptive region is immersed and water absorption of the filter main body is prevented by a watertight section having a non water absorbability are continuously alternated.Type: GrantFiled: July 14, 2008Date of Patent: August 6, 2013Assignee: Sharp Kabushiki KaishaInventors: Tsutomu Tsuda, Yoshihiko Matsubara, Naoyukl Shigemoto, Hiroshi Kitagaito
