    摘要: A polygon scanner has a lighter rotating shaft on which a polygon mirror is mounted, to prevent a positional deviation of the polygon mirror from the rotating shaft in high speed rotation, in which the rotating shaft is supported through a dynamic pressure air bearing on a fixed shaft, in which the polygon mirror and motor constituent members are mounted on the rotating shaft, and in which the rotating shaft and the polygon mirror are made of respective light weight materials matched with each other in coefficient of thermal expansion, for example of aluminum or an aluminum alloy. Further, an anodic oxide film is formed at least on a portion where the rotating shaft could contact with the fixed shaft, and floating means is provided for constantly floating the rotating shaft relative to the fixed shaft upward in an axial direction thereof. A process for producing the polygon scanner comprises making a predetermined masking on a portion where the rotating shaft could contact with the fixed shaft, prior to an anodic oxidation treatment to form an anodic oxide film on the portion, and then performing the anodic oxidation treatment, whereby, during the treatment, forming an anodic oxide film and a pattern of recesses and protrusions for dynamic pressure generation corresponding to a pattern of the masking, which are constituent elements of a dynamic pressure air bearing.

    摘要: Herein disclosed is an optically reflecting code plate having a number of reflective and unreflective portions formed alternately on the surface of its substrate. This substrate is made of aluminum of high purity, for example, and has its surface anodized with a colorless, transparent and porous aluminum oxide film. At predetermined positions of the oxide film, which are to be formed with the aforementioned unreflective portions, moreover, metal such as nickel, tin, copper, iron, cobalt, silver, manganese or selenium is deposited by electrodeposition in the bottoms of the pores of the oxide film thereby to form a metal-deposited layer. Moreover, the vicinities of the openings of the aforementioned pores are impregnated with a dye such as a black metallized complex salt dye or a Nigrosine dye to form a dye-impregnated layer. The aforementioned metal-deposited layer and the dye-impregnated layer are overlaid the later over the former thereby to form the unreflective portions. The remaining portion shaving neither the metal-deposited layer nor the dye-impregnated layer so that it is exposed directly to the outside is left as the reflective portions.

    摘要: A sulfur dioxide-containing analysis stream, such as formed by the oxidative pyrolysis of a sulfur-containing liquid, is passed through a trapping medium comprising metal or metal oxide, preferably nickel oxide, wherein the sulfur dioxide is retained while the remainder of the gas flows through. Thereafter, the flow of analysis gas is discontinued and the trap zone is heated to release the sulfur dioxide, which is passed in an inert carrier gas stream through a sulfur dioxide detector such as a conductivity cell. Halides in the analysis stream are removed prior to trapping by being dissolved in an aqueous liquid in a scrubbing chamber. Such chamber is regenerated by vaporizing the halide-containing aqueous solution and venting it. Also, a system of the foregoing type including two traps and a single detector whereby two samples are alternately analyzed and trapped to reduce the overall analysis time.

    摘要: A three phase process for determining total organic halides in water. The first phase is a sorptive process including passing a liquid through a packed bed of sorptive material thereby removing quantitatively, purgeable and non-purgeable, organic halides and thereafter passing an inorganic halide displacement wash solution through the bed to displace inorganic halides. The second and third phases are a combination combustion and titration whereby organic bromides and other organic halides entering the combustion phase are quantitatively titrated coulometrically. The second and third phases include in a first heating zone heating a sample, such as the sorptive material following the first phase, in the presence of a mild oxidant to a temperature sufficient to vaporize water; in a second heating zone heating any remaining sample from the first heating zone and gases therefrom in the presence of an oxidant to a temperature sufficient to complete combustion of the sample and gases; and concurrently titrating coulometrically the gases from the second heating zone.

    摘要: A conveying device includes a conveyor, a detector, and circuitry. The conveyor conveys a recording medium in a conveyance direction. The detector detects a skew amount and a shift amount of a posture of the recording medium to be sent to the conveyor and detects, in parallel, end positions of the recording medium in a width direction of the recording medium intersecting with the conveyance direction, at at least three different points in the conveyance direction on one end of the recording medium in the width direction. The circuitry controls an operation of the conveyor and causes the detector to detect a corner folded portion of the recording medium based on the end positions of the recording medium in the width direction detected at the at least three different points.
