Abstract: According to a method for producing an inorganic iodide in accordance with the present invention, it is possible to efficiently produce a highly pure inorganic iodide by reacting a hydrogen iodide gas with an inorganic base compound by bringing the hydrogen iodide gas into contact with the inorganic base compound. As such, it is possible to provide a simple and efficient method for producing an inorganic iodide.

Abstract: A system (100) of the present invention for producing an iodine compound includes: a raw material adjusting unit (1) for supplying hydrogen-containing gas to at least one of liquid iodine in an iodine melting pot (4) and gaseous iodine obtained by evaporating liquid iodine so as to obtain a mixture gas; a hydrogen iodide producing unit (10) including a hydrogen iodide producing tower (12) having a catalyst layer (12a) for converting the introduced mixture gas into crude hydrogen iodide gas; a hydrogen iodide refining unit for removing unreacted iodine from the introduced crude hydrogen iodide gas so as to obtain hydrogen iodide gas; and an iodine compound producing unit (30) for producing a target iodine compound from the obtained hydrogen iodide gas and a reaction material. This allows producing an iodine compound with high purity easily, efficiently, and with low cost.

Abstract: An object of the present invention is to provide a method for recovering iodine, which can be carried out simply and economically without practicing mixing processing operation of iodine-containing material, an alkali metal compound and a solvent in advance before introducing to a combustion furnace. The object of the present invention can be attained by a method for recovering iodine which comprises feeding an iodine-containing solution containing iodine and/or iodine compound, a basic alkali metal compound solution and/or a basic alkaline earth metal compound solution separately to a roasting furnace, oxidatively decomposing a combustible material by heat treatment, and absorbing iodine and/or iodine salt contained in a component at heat treatment exit with water or an aqueous solution.

Abstract: A color printer comprises a recording sheet tray 3 capable of storing numerous recording sheets 2, a sheet feed/discharge roller 293 feeding an uppermost recording sheet 2 from the recording sheet tray 3 to a platen roller 7, and a clamp mechanism section 13 clamping a front end of a recording sheet 2 loaded on the platen roller 7 at a predetermined fixed position. A driving device rotates the platen roller 7 to reciprocate the loaded recording sheet 2 in forward and backward directions every time when each of plurality of color images, such as yellow (Y), magenta (M), and cyan (C), is printed on the loaded recording sheet 2. A sheet transportation path is defined between the sheet feed/discharge roller 293 and the clamp mechanism section 13 for transporting the loaded recording sheet 2 forward and backward. This sheet transportation path is shorter in length than the recording sheets 2.

Abstract: A color printer for recording an image having at least two colors on a recording sheet with a recording head being brought into contact with a platen roller in a state that the recording sheet is interposed therebetween, the two colors being successively printed on a surface of the recording sheet with the recording sheet being operated to reciprocate with respect to a recording position on the platen roller. The printer includes a clamping device provided at a downstream side of the recording head in a sheet-travelling path from a supply section of the recording sheet to a discharging section of the recording sheet for holding the recording sheet when recording the image. The clamping device is fixed with respect to the recording position so that a distance between a holding position of the recording sheet taken by the clamping device and the recording position on the platen roller is always constant during the image recording.
