Abstract: Provided is a die lip driving structure for adjusting a gap between a first lip and a second lip by applying a pressing load or a tensile load to a flexible lip portion which forms at least one of the first lip and the second lip provided in a die body, the die lip driving structure including: a lever supported by a rotating shaft as a fulcrum; and an operating rod which is supported to be displaced in an axial direction by the die body. A rotational force of the lever is converted into a force in the axial direction of the operating rod, and the force in the axial direction becomes a pressing load or a tensile load exerted on the flexible lip portion. The lever directly applies a force to the operating rod at the point of action of the lever.

Abstract: A carrier supporting titania thereon is further caused to carry a metal compound thereon. This metal compound is hydrogen reduced in a heating atmosphere at a first treatment temperature, then oxidized in a heating atmosphere at a second treatment temperature not higher than the first treatment temperature to thereby obtain a photocatalyst. In this event, metal is released from an extremely strong reduction state and thus highly dispersed on the catalyst in the form of fine particles so that high activity of the catalyst can be obtained. Then, by purifying gas while feeding light and heat to the photocatalyst by, for example, blacklights, a volatile organic compound such as acetaldehyde can be decomposed at a high decomposition rate through cooperation between photocatalytic activity and thermal catalytic activity of the photocatalyst.

Abstract: Titania is dissolved in a hydrogen peroxide solution to produce an amorphous titania gel, then the amorphous titania gel and a hydrogen peroxide solution are mixed together to produce an amorphous titania sol, and then an alkali solution is supplied to the solution containing the amorphous titania sol to thereby adjust a pH of the solution to 2 to 10. Even if the obtained solution containing amorphous titania is, for example, left to stand at normal temperature for a long time, gelling or aggregation of titania can be suppressed. That is, it is possible to obtain a titania solution that can maintain the state where fine particles of titania are highly dispersed in the solution, over a long term.

Abstract: The present invention provides a mortar tile which can reduce labor, time and cost required for installation without reducing a harmful substance decomposing ability using a photoresist. To achieve such an object, a mortar which is molded in a tile shape is manufactured by forming a formed article in a state that a photocatalyst is added to the mortar and, thereafter, the pressure-forming is performed at a pressure which allows the formation of open pores in a surface thereof, and a photocatalyst is applied to a surface of the formed article.
