Patent number: 8745772Abstract: A discharge valve apparatus has control cylinder members for controlling the flow of rinse water flowing out from a reservoir tank discharge port, on which opening portions are formed, and flow-adjusting members attached to these control cylinder members are capable of adjusting the opening surface area of opening portions in the control cylinder member. Female engaging portions in the control cylinder member are arrayed approximately vertically, and are furnished with registration indentations for registering the attachment positions of adjusting members relative to the control cylinder members. Intervals within the registration indentations are set to be smaller than a width of an installer's finger to prevent release of engagement by an installer when the adjusting member male engaging portions are in a state of engagement with the female engaging portions of the control cylinder members.Type: GrantFiled: April 9, 2012Date of Patent: June 10, 2014Assignee: Toto Ltd.Inventors: Tsutomu Kido, Yukinori Kubozono, Haruki Matsuda, Hisashi Koga

Patent number: 6436325Abstract: A method of manufacturing a cellulose based fiber of high water-retentivity. The cellulose based fiber of high water rententivity is manufactured by mixing together a stock solution as a homogeneous mixture of a non-cellulose based material of high absorbency and a cellulose based material and a stock solution singly composed of cellulose based material by means of a nozzle. Then the mixture is formed into a complex fiber as a sheath-core type by spinning, elongation and refining the mixture.Type: GrantFiled: March 17, 2000Date of Patent: August 20, 2002Assignee: Uni-Charm CorporationInventors: Tsutomu Kido, Noriyuki Kimura, Ichiro Takeuchi, Kazuya Umino

Patent number: 6248444Abstract: A powdered super absorbent polymer (SAP) has heretofore been used as a water retentive material for sanitary products, such as sanitary napkin, disposable diaper and incontinence pad. This water retentive material is used by being held between two paper sheets but the powdered SAP comes off easily from absorbent member. Moreover, even when the SAP is in a dried powdered state or in a water-absorbed gel state, it is moved between a top sheet and a back sheet in accordance with the movement of a wearer of the sanitary product. Consequently, water absorbency decreases with poor shape stability. Moreover, since the SAP in a water-absorbed gel state is sticky, the wearer feels unpleasant. According to the present invention, therefore, a cellulose fiber, such as a viscose rayon fiber containing uniformly a non-cellulose based material of high water absorbency such as polyacrylate salt is manufactured.Type: GrantFiled: August 31, 1999Date of Patent: June 19, 2001Assignee: Uni-Charm CorporationInventors: Tsutomu Kido, Noriyuki Kimura, Ichiro Takeuchi, Kazuya Umino
