Abstract:
A ceramic product to be used around water which has a coating film comprising an antifouling agent on its working surface, characterized in that the antifouling agent has a silicon-containing functional group capable of binding with a hydroxyl group being present in the working surface of the ceramics product by dehydration or dehydrogenation. The ceramics product to be used around water exhibits excellent antifouling properties.
Abstract:
Providing a product with a glass layer which can be manufactured at low costs and achieve an outstanding antibacterial effect. Accordingly, in the product comprising a base with the glass layer, the glass layer has at the surface side a rich layer containing a high concentration of Ag ion.
Abstract:
Belt-like portions (2) are formed around the entire periphery of the upper surface of the block (1) by cutting off the periphery in such a manner as to be recessed inward, and to form steps between the belt-like portions, and the upper surface of the block. The upper end portions of adjacent blocks do not come into mutual contact when they push each other.
Abstract:
A normally closed liquid control valve having both an automatic outlet side pressure regulating function and a sealing function, comprising a pressure regulating piston moving in a housing to detect a balance point between an outlet side pressure and the spring force of a pressure regulating spring installed against the outlet side pressure, a movable valve seat fitted to the pressure regulating piston and moving together with the pressure regulating piston, and a valve element seated on the valve seat by a valve closing force caused by an inlet side pressure and the spring force of a sealing spring to close the valve and unseated from the valve seat when an external valve opening force larger than the valve closing force is applied thereto to open the valve, whereby the automatic outlet side pressure regulating function by the movement of the pressure regulating piston and the sealing function by the closing of the valve can be developed.
Abstract:
The present invention provides an open/close valve which contributes the stabilization of the operation responsibility. A housing has a water-in port and a water-out port. Furthermore, a piston which is slidably mounted in the housing in an axial direction by means of an external operation of a shaft, and a pressure offset means for offsetting the pressure which the piston receives from water in the water-out port to the other side are provided. The piston is attached to a seat face of the housing by being slided on one side in an axial direction to close the communication between the water-in port and the water-out port, and the piston is detached to the seat face of the housing by being slided on the other side in an axial direction to open the communication between the water-in port and the water-out port. The pressure offset means comprises a pressure offset room which is formed at the other side of the piston, and a passage for communicating one side of the piston with the pressure offset room.
Abstract:
A toilet bowl flushing device and a toilet bowl flushing method capable of making compatible higher discharge capacity with higher water saving effect. The toilet bowl flushing device comprises a water feed means feeding wash water to the bowl (2) of a toilet bowl (1), a drain flow passage (5) continued with the downstream side of the water sealing part (4) of the toilet bowl (1), an air suction means sucking air from the drain flow passage (5), and a control means controlling the water feed means and the air suction means. The control means starts to feed the wash water to the water sealing part (4) via. the bowl (2) by operating the water feed means to flush the toilet bowl (1), and after a level in the bowl (2) rises, operates the air suction means.
Abstract:
A silencer capable of realizing reliable noise prevention while realizing production cost reduction and assembly simplification; and a water supply device having this silencer effect. A silencer (2) connected to a jet pipe (1) which allows water passing through an interior water supply passage (1a) to deliver into stored water (W). It includes a cylindrical sleeve (4) downwardly connected to the upstream side of the jet pipe (1) and internally having a water flow passage (4a) communicating with the water supply passage (1a), and a housing (3) water-tightly connected to the upstream side of the jet pipe (1) and to the upper portion of the sleeve (4) and also water-tightly connected to the downstream side of the jet pipe (1) while surrounding the lower portion of the sleeve (4), and making it possible for the air in the jet pipe (1) to be stored in the interior which is outside the sleeve (4). A vent hole (4b) is formed through the upper portion of the sleeve (4) to communicate the water flow passage (4a) with the interior of the housing (3).
Abstract:
A western-style water closet capable of positively enhancing the cleaning performance of the western-style water closet body without sacrifice in the performances of components constituting a functioning device, comprising a western-style water closet body, and a private parts cleaning device provided at the rear portion of the water closet body. The private parts cleaning device is provided to be liftable so as to expose the rear portion of a ball surface of the water closet body. A second parts group capable of being exposed when the private parts cleaning device is lifted, or a concealing member for concealing a space are provided.
