摘要： An image reading device comprising a rotary polygon mirror (6) for scanning a light flux from a light source (1), an imaging optical system (4) for forming on a reflection plane of the mirror (6) a linear image larger than the width in a main scanning direction of the one reflection plane, and a curved-face mirror (7), wherein the light source (1), the imaging optical system (4), the rotary polygon mirror (6) and the curved-face mirror (7) are disposed in different positions in a sub-scanning direction, a light flux from the imaging optical system (4) shines obliquely onto the polygon mirror (6), and a light flux reflected off the mirror (6) beams obliquely onto the curved-face mirror (7). Since one curved-face mirror can beam a light flux reflected from the rotary polygon mirror onto a surface to be scanned and the rotary polygon mirror having a small inscribed radius and many reflection planes can be used, satisfactory optical performance and high-speed feature can be realized.

摘要： By a first image forming optical system (42a to 42d), a plurality of light beams from light sources (41a to 41d) form linear images on a common deflecting surface (46) of an optical deflector (44). Light beams reflected off the optical deflector (44) are reflected by a plurality of curved surface mirrors (45a to 45d) and are allowed to scan over photosensitive members (4a to 4d), respectively. The plurality of curved surface mirrors (45a to 45d) are disposed on the same side with respect to a plane that includes a normal line at a center of the deflecting surface (46) and is parallel to a main scanning direction. Further, curved surfaces of the plurality of curved surface mirrors (45a to 45d) vary in shape. Thus, a tandem type color image forming apparatus that achieves low cost and has excellent optical performance and an optical scanning device that is used favorably in the color image forming apparatus can be provided.

摘要： A light quantity distribution control element includes a substrate of 20 mm×20 mm×3 mm made of a material that transmits light, such as optical glass or acryl, and a antireflective structure provided on a surface of the substrate. As the antireflective structure, a conical antireflective structure of a pitch of 0.15 μm (periodic structure having conical convexities) is formed. This corresponds to a antireflective structure having a pitch of a wavelength or less in the ultraviolet band (150 nm to 400 nm) at the time when ultraviolet light is used as incident light.

摘要： In treatment of water by injection of ozone into the water for removal of harmful matters, odor matters, and color matters therein, either or both of a nonyl phenol and a cresol are added to the water to be treated. The nonyl phenol is added together with a lower alcohol or acetone to the water to be treated. The cresol is added together with a lower alcohol or acetone to the water to be treated. A p-nonyl phenol is added as the nonyl phenol for treatment. As the cresol for addition, a p-cresol is added. As the nonyl phenol for addition, a nonyl phenol is used such that two molecular weights of 220 and 107 are detected when measured by either or both of gas chromatography and mass spectrometry. By the above treatment, the decomposition reaction of ozone can be accelerated, and thereby it becomes possible to accelerate the oxidative decomposition reaction of organic matters, the amount of ozone required for the decomposition of harmful matters can be reduced with the decomposition time. The decomposition rate of organic matters can be accelerated by addition of a nonyl phenol or a cresol. Accordingly, when the process for accelerating the reaction of ozone is applied in water treatment, the treatment rate of water can be enhanced. The treatment volume per time of water can be enhanced, whereby the site area for water treatment facilities can be reduced even in the event that the capacity of a reaction tank is reduced.

摘要： A plurality of types of ink having different wavelength characteristics are used for multiple printing of code information. When two or more types of ink are to be printed in an overlapping manner, in a region 8 in which one type of ink 4 and another type of ink 5 are printed in the overlapping manner, the ink 4 and the ink 5 are printed so as not to completely overlap each other by using a checkered pattern 9. As a result, the multiple printing can be performed without strict constraints on the wavelength characteristics of the ink.
