Patent number: 7191473Abstract: When a user sets water power using a water power adjustment switch in a remote control device, a controller controls the period of pressure fluctuations, the width of pressure fluctuations, and the central pressure of the discharge pressure of a pump on the basis of a signal transmitted by radio from the remote control device. When the user sets the divergent angle of washing water using a washing area adjustment switch in the remote control device, the controller controls the divergent angle of the washing water sprayed from a posterior nozzle on the basis of the signal transmitted by radio from the remote control device. Consequently, the washing water supplied to a side surface of a cylindrical swirl chamber from a first flow path in the posterior nozzle is sprayed from a spray hole as dispersed spiral flow, and the washing water supplied to a lower part of the cylindrical swirl chamber from a second flow path in the posterior nozzle is sprayed from the spray hole as linear flow.Type: GrantFiled: January 14, 2003Date of Patent: March 20, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tomohide Matsumoto, Hideki Ohno, Kazushige Nakamura, Shigeru Shirai, Hiroaki Fujii, Shinichi Maruyama, Muneo Tao

Publication number: 20050246828Abstract: When the human body is washed, washing water is sprayed on a surface to be washed of the human body from a posterior nozzle and a bidet nozzle. On the other hand, when the human body is not washed, the posterior nozzle and the bidet nozzle are subjected to high-temperature cleaning by a nozzle cleaning nozzle. When it is detected that a sanitary washing apparatus has not been employed yet, the posterior nozzle and the bidet nozzle are allowed to be cleaned by the nozzle cleaning nozzle by a controller. After a cleaning operation is terminated, a user is notified that the cleaning operation is terminated by a notification lamp and a speaker. A scale inhibiting material supply device is interposed in a pipe on the upstream side of an instantaneous heating device by the nozzle cleaning nozzle.Type: ApplicationFiled: August 22, 2003Publication date: November 10, 2005Inventors: Shigeru Shirai, Tomohide Matsumoto, Hideki Ohno, Kazushige Nakamura, Toshinari Matsumoto, Mitsuyuki Furubayashi, Takemi Oketa

Patent number: 6503962Abstract: The present invention is for providing a synthetic resin composition capable of effectively deodorizing amine malodor causing substances such as trimethyl amine. In a synthetic resin composition comprising an aqueous medium, a surfactant, and a polymer latex and a filler dispersed in the aqueous medium by the surfactant, a transitional metal supported silica gel having at least one selected from the group consisting of a transitional metal and a transitional metal compound supported by a silica gel and an activated carbon were used as the filler. Since the transitional metal or the transitional metal compound has an performs extremely well as a Lewis acid, it forms a complex with a Lewis base having an unpaired electron. That is, a malodor causing substance such as amines and ammonia having a nitrogen atom with an unpaired electron can be adsorbed efficiently.Type: GrantFiled: December 9, 1999Date of Patent: January 7, 2003Assignees: Toyoda Boshoku Corporation, Dainippon Ink and Chemicals, Inc.Inventors: Tomiko Mouri, Kazuhiro Fukumoto, Seiji Onoda, Yoshio Yamada, Hideki Ohno, Masako Furuta, Akihiro Matsuyama, Shigeyoshi Miura, Shirou Ueda
