Publication number: 20240126195Abstract: A fixing apparatus to fix a toner image to a printing material while nipping and conveying the printing material at a fixing nip includes a film, a guide member, a nip-forming member in a recess of the guide member, a roller, a support member, and a moving mechanism. The guide member in an inner space of the film guides film rotation. The roller is in contact with a film outer circumferential surface. The roller sandwiches the film with the nip-forming member to form the fixing nip. When disposed in the recess, the nip-forming member is movable in a direction parallel to a conveying direction of the printing material. The support member is fixed to an end of the nip-forming member in a longitudinal direction. The moving mechanism moves the support member relative to the guide member in the direction parallel to the conveying direction.Type: ApplicationFiled: October 16, 2023Publication date: April 18, 2024Inventors: FUYUKO KOYAMA, KENICHI OGAWA

Patent number: 10493036Abstract: A capsule excellent in enteric property with the assumption that gelatin is used as a main base material of the capsule coating. An alkali-treated gelatin and carrageenan are contained as base materials of the capsule coating. In the gastric (aqueous) environment, the alkali-treated gelatin which is positively (+) charged coexists with the carrageenan which is negatively (?) charged, and amino groups (NH4+) in the gelatin react with sulfate groups (SO3?) in the carrageenan so that the capsule coating is insolubilized. On the other hand, in the intestinal (aqueous) environment, the alkali-treated gelatin which is negatively (?) charged coexists with the carrageenan which is negatively (?) charged, and the amino groups (NH4+) in the gelatin are repulsive to the sulfate groups (SO3?) in the carrageenan so that the capsule coating quickly disintegrates and dissolves.Type: GrantFiled: August 10, 2016Date of Patent: December 3, 2019Assignee: SUNSHO PHARMACEUTICAL CO. LTDInventors: Takayuki Fukasawa, Kenichi Koyama, Tomoya Suzuki
