  • Patent number: 7191473
    Abstract: 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.

  • Publication number: 20050246828
    Abstract: 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.

  • Patent number: 6503962
    Abstract: 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.

  • Patent number: 6206671
    Abstract: A pressure molding apparatus comprises a furnace defining a heating space for accommodating a mold assembly including a mold body charged with a raw material to be molded, and a pressure piston for pressurizing the raw material; heating means for heating the heating space; and load imposing means for imposing a load on the pressure piston to mold the raw material. The load imposing means includes at least one weight means and weight supporting means. The weight supporting means is selectively set in a load-free state in which the weight supporting means supports the weight means so that the weight of the weight means is not imposed on the pressure piston, and a load imposed state in which the weight supporting means releases the support of the weight means so that the weight of the weight means is imposed on the pressure piston.
