According to an aspect of the present invention, a toilet device includes: a washing unit washing a surface of a bowl in a toilet bowl; a water supplying unit supplying washing water to the washing unit; a silicic acid polymerization inhibiting unit adding inhibitor for silicic acid polymerization to the washing water left on the surface of the bowl after the washing of the bowl, the inhibitor inhibiting polymerization of silicic acid component in the washing water left on the surface of the bowl; and a control portion executing a control starting an operation of the silicic acid polymerization inhibiting unit before the surface of the bowl is evaporated.

Toilet device

To provide a urinal apparatus, including: a water supplying device configured to supply water to a bowl section of a urinal; a trap section provided in a lower part of the bowl section and configured so that urine and water flow into the trap section; and a water sprinkling device configured to sprinkle water droplets to a region inside the bowl section, the region being located between the trap section and position of a nose of a user facing the bowl section, wherein the timing of sprinkling the water droplets by the water sprinkling device being different from timing of supplying water by the water supplying device.

Urinal with separate water supplying and water spraying devices

A urinal with a sanitation device capable of preventing the generation of a smell and urine scale with reliability without reducing a water conservation effect. In the urinal US, a liquid agent is ejected in different modes by predetermined timing according to areas on the urinal US.

Hydrogen sulfide is dehydrogenated to generate a HS group and an S group. The HS group is oxidized to generate sulfuric acid, which is bonded to a metal. The S group is polymerized with a CH,S group to generate methyl trisulfide or methyl tetrasulfide, which is adsorbed to an adsorbent. Methyl mercaptan is dehydrogenated, for example, to generate a CH,S group. A portion of the CH,S group is oxidized to generate methanesulfonic acid, which is bonded to a metal. Another portion of the CH,S group is polymerized with the CH,S group itself to generate methyl disulfide, at least a portion of which is adsorbed to an adsorbent. Still another portion of the CH,S group is polymerized with the S group to generate methyl trisulfide or methyl tetrasulfide, which is physically adsorbed to an adsorbent. In this manner, malodor components including hydrogen sulfide and methyl mercaptan can efficiently be removed without producing or release of harmful secondary products. A simple-structure, compact deodorizing apparatus including appropriate metal oxide catalyst and an adsorbent material suitable for achieving the above deodorizing functions is incorporated in a toilet bowl.

An apparatus for scribing grain-oriented electrical steel strip has a movable die attached to a reciprocating drive and an opposite fixed die. A strip held between the two dies is scribed by the action of the movable die that is moved back and forth by the reciprocating drive. The fixed die positioned with the stroke of the movable die is supported by a plurality of cylinders connected to an accumulator whose pressure is preset to a level of the deformation resistance corresponding to the amount of deflection that varies with the depth of the impressions scribed on the strip.
