    • [PROBLEMS] A light guide and a line illuminator incorporating it in which the deterioration of a read out image can be suppressed even when the document surface is floating by spreading the intensity distribution of light in the longitudinal direction at a position (document position) of an article being illuminated. [MEANS FOR SOLVING PROBLEMS] In a light guide (10) arranged such that a light entering from the end face exits from an exit face provided along the longitudinal direction while reflecting off the inner surface, a side face shape orthogonal to the longitudinal direction has a curved surface (1) of first elliptic arc, a curved surface (2) of second elliptic arc, a first exit face (3), a second exit face (4), and a light scattering part (5) formed at an elliptic focal position (or in the vicinity thereof) on the major axis plane of each ellipse. Condensing position of a light reflected off the first curved surface is different from the condensing position of a light reflected off the second curved surface.

    • A plate glass fitting structure for fitting plate glass to a fixed member equipped with a groove portion capable of receiving the peripheral edge portion of plate glass. According to conventional plate glass fitting structures, plate glass is likely to fall off the fixed member at the time of the occurence of a fire, etc. In the present invention, pairs of engagement portions (3b, 5) for preventing fall off of plate glass (2) from the groove portion (3a) are disposed dispersedly at the peripheral portions of the fixed member (3) and those of plate glass so that the plate glass (2) and the groove portion (3a) engage with each other while the plate glass (2) is fitted into the groove portion (3a). Therefore, even in the case of a fire, plate glass is prevented from falling off the fixed member.

    • Incorporating fluorine into a photocatalyst layer made of an oxide semiconductor such as titanium oxide serves to enhance the photocatalytic activity of the oxide. The photocatalyst may take in itself the form of film, flake, particle, powder or fiber. Alternatively, it can be used in a state applied on the surface of a substrate taking the form of plate, film, flake, particle, rod, fiber or the like. When the substrate has an alkali-containing glass composition, forming a layer of a metal oxide, such as silicon oxide, containing fluorine as the fluorine-containing layer between the substrate and a photocatalyst layer serves to protect the photocatalytic activity of the photocatalyst layer from lowering caused by the diffusion of alkali metal ions (such as Na ion) of the glass substrate into the photocatalyst layer, because the metal oxide layer functions as alkali barrier. Supported photocatalysts prepared by using an inorganic fiber or glass sheet as the substrate have an extremely excellent decomposition power against dilute harmful organic gases, thus being useful as the wall covering and air filters for the clean closed space and clean closed transfer space for semiconductors, various clean rooms, office buildings and general housing, and being effective in air cleaning of room, destruction of microorganisms, inhibition of stain, protection of transparent panels from misting (retention of hydrophilicity) and so on.
    • 将氟结合到由诸如氧化钛的氧化物半导体制成的光催化剂层中用于提高氧化物的光催化活性。 光催化剂本身可以是薄膜,薄片,颗粒,粉末或纤维的形式。 或者,其可以以施加在板,膜,片,颗粒,棒,纤维等的形式的基板的表面上的状态使用。 当基板具有含碱玻璃组合物时,在基板和光催化剂层之间形成含有氟作为含氟层的氧化硅等金属氧化物层用于保护光催化剂层的光催化活性 由于金属氧化物层作为碱性阻挡层,玻璃基板的碱金属离子(例如Na离子)扩散到光催化剂层中引起的降低。 通过使用无机纤维或玻璃板作为基材制备的负载型光催化剂对稀有害有机气体具有非常优异的分解能力,因此可用作清洁封闭空间的覆盖层和空气过滤器以及用于半导体的各种清洁的封闭传递空间 洁净室,办公楼和普通住房,有效的空气清洁,微生物的破坏,污渍的抑制,透明板的保护(保持亲水性)等。
