Abstract: A flux application state inspection device that inspects a transparent or translucent flux applied to an electrode of a circuit board, including: a first illuminator that emits first irradiation light that is ultraviolet light or visible light at a first incident angle not less than 0 degree and not greater than 30 degrees; a second illuminator that emits second irradiation light that is visible light having red or green color, at a larger incident angle than the first incident angle; an imaging device that is disposed above the circuit board such that an optical axis of the imaging device is orthogonal to the circuit board, takes a first image of light radiated from the first illuminator and reflected from the circuit board, and takes a second image of light radiated from the second illuminator and reflected from the circuit board.

Abstract: A flux application state inspection device includes an illumination device that irradiates, with ultraviolet light, a circuit board having electrodes on which a flux capable of absorbing the ultraviolet light is applied; an imaging device that takes an image of the ultraviolet light radiated to the circuit board; and a central processing unit (CPU) that: sets, with a reference portion of the circuit board as a reference, an inspection area on the circuit board for each component to be mounted on the circuit board, wherein the inspection area corresponds to the component and includes two or more of the electrodes on which the component is mounted, and detects whether an application state of the flux is defective or non-defective, based on the image obtained by the imaging device while the inspection area is irradiated with the ultraviolet light by the illumination device.

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.
