Patent number: 9687814Abstract: Provided is a fibrous adsorbing material used for the adsorption and recovery of metals in a solution, which is a fibrous metal-adsorbing material that can be produced using existing production facilities without using special facilities or complicated operations, has high durability, is easy to diversify, and can be processed into various forms. The fibrous metal-adsorbing material is produced by a) a step of preparing an acrylate polymer having a large number of glycidyl groups in the molecule, b) a step of kneading a low-melting-point fiber matrix polymer therewith, c) a step of making the resulting mixture into a fibrous form by an melt-blend spinning method, and d) a step of allowing a long-chain ligand having an amino group or an imino group to react with glycidyl groups on the fiber surface to introduce a metal-adsorbing functional group. The fibrous metal-adsorbing material has high durability, is easy to diversify, and has various forms.Type: GrantFiled: August 26, 2013Date of Patent: June 27, 2017Assignee: NIPPON FILCON CO., LIMITEDInventors: Yoshinori Inoue, Toshifumi Katoh, Takehiro Kajiwara, Mitsuru Saito

Patent number: 9630537Abstract: Embodiments of the present invention include a vehicle interior component. The vehicle interior component has a cover forming a design surface, and a tag attached to the cover. The tag has a first piece, a second piece and an attachment portion for attaching the first piece to the cover. The second piece has a first end integrated with the first piece, and a second end attached to the cover directly or indirectly. The second piece is laminated on the first piece while covering the attachment portion. Thus, the second piece is capable of using the attachment portion to suppress impairment of the design property of the vehicle interior component. The tag is attached to the cover in a manner helping to achieve a satisfactory outward appearance.Type: GrantFiled: June 20, 2014Date of Patent: April 25, 2017Assignees: TOYOTA BOSHOKU KABUSHIKI KAISHA, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takehiro Kajiwara, Michiaki Kojima

Patent number: 9592489Abstract: Problem The present invention provides, in a metal-adsorbing material used for the removal and recovery of a wide range of heavy metals in treated solutions such as industrial waste water, service water, and environmental water, a gel-like metal-adsorbing material having a large amount of metal adsorption and capable of meeting various demands; and also provide a metal adsorbent having a gel-like metal-adsorbing material supported on a porous carrier. Means for Resolution A metal-adsorbing polymer selected from polyethyleneimine and polyallylamine is crosslinked with a polyglycidyl ether, whereby a gel-like metal-adsorbing material having a large amount of metal adsorption and capable of meeting various demands is produced.Type: GrantFiled: January 27, 2013Date of Patent: March 14, 2017Assignee: NIPPON FILCON CO., LIMITEDInventors: Yoshinori Inoue, Takehiro Kajiwara, Toshifumi Katoh, Mitsuru Saito

Publication number: 20140042792Abstract: A clip that hooks, and thus fixes, a cover of a seat onto a frame structure includes a cover connecting portion that is integrally connected to the cover; a hook-shaped hook portion that hooks onto, and thus fixes to, the frame structure; and a planar covering portion that is formed in a position facing a back side portion of the hook portion. An opening that enables the back side portion of the hook portion to be visible is formed in the covering portion.Type: ApplicationFiled: August 2, 2013Publication date: February 13, 2014Applicant: TOYOTA BOSHOKU KABUSHIKI KAISHAInventor: Takehiro KAJIWARA
