摘要:
A sodium-based dechlorinating agent is added to a flue gas; hydrogen chloride contained in this flue gas is removed as residue of dechlorination; the thus removed residue of dechlorination is dissolved by adding water; water-insoluble constituents are separated from the resulting aqueous solution; and after adjusting pH of the aqueous solution remaining after separation of the water-insoluble constituents, mercury, dioxin, and the like are removed and discharged. The sodium-based dechlorinating agent is mixed with a hydrophilic anti-caking agent, with an angle of repose of 40° or more, a dispersibility of less than 50, and a floodability index value of less than 90. This permits inhibition of occurrence of a pressure drop and leakage in the filter cloth of the dust collector.
摘要:
A sodium-based dechlorinating agent g is added to a flue gas G6; hydrogen chloride contained in this flue gas is removed as residue of dechlorination; the thus removed residue of dechlorination is dissolved by adding water i; water-insoluble constituents k are separated from the resulting aqueous solution j; and after adjusting pH of the aqueous solution 1 remaining after separation of the water-insoluble constituents k, mercury, dioxin and the like are removed and discharged. The sodium-based dechlorinating agent g is mixed with a hydrophilic anti-caking agent, with an angle of repose of 40° or more, a dispersibility of less than 50, and a floodability index value of less than 90. A mean particle diameter of sodium hydrogencarbonate is set within a range of from 2 &mgr;m to 30 &mgr;m. The hydrophilic anti-caking agent comprises silica, and is contained in an amount of 0.1 mass % or more in the sodium-based dechlorinating agent. Further, a mean particle diameter of the hydrophilic anti-caking agent is set within a range of from 0.001 &mgr;m to 1 &mgr;m. This permits inhibition of occurrence of a pressure drop and leakage in the filter cloth of the dust collector.

An image forming control apparatus for controlling an image forming apparatus to form an image on a recording medium includes a memory to store a target property data of original gradation values of image data of a target image to be formed on the recording medium; and circuitry to acquire actual property data of the target image actually formed on the recording medium, convert the original gradation values to another gradation values, generate a primary correction data based on the original gradation values and the another gradation values, generate a secondary correction data to supplement the generated primary correction data, compare the primary correction data and the secondary correction data, and generate gradation correction data used for correcting the original gradation values existing in a specific range of the original gradation values based on a comparison result of the primary correction data and the secondary correction data.
摘要:
An image processing apparatus includes a storage unit that stores therein a type of surface effect and predetermined glossiness in association with each other, a determining unit that determines, as first glossiness, the glossiness associated with the surface effect specified by the gloss control plane data, a measurement control unit that performs control to measure second glossiness indicating actual glossiness of a printed matter that is a recording medium on which printing has been performed by a printing apparatus, a generation unit that produces, from the gloss control plane data, gloss plane data for additional printing in which a density value is set in accordance with an amount of a transparent color material necessary for achieving the first glossiness on the basis of a difference in value between the first glossiness and the second glossiness, and an output unit that outputs the gloss plane data for additional printing.
摘要:
A valve opening-closing timing control device includes a solenoid valve having a solenoid mechanism provided with a spool having an oil path groove formed in an outer face thereof, and a sleeve for housing the spool to reciprocate and slide. A wall surface of the sleeve has a first port communicating with a first hydraulic oil supply section, a second port communicating with a second hydraulic oil supply section, and a third port communicating with the side of a hydraulic oil supply source. The spool is driven and set to a first position for supplying hydraulic oil from the hydraulic oil supply source to the first port, a second position for supplying the hydraulic oil from the hydraulic oil supply source to the second port, and a third position outside an area between the first and second positions to prevent supply of hydraulic oil from the first and second ports.
摘要:
In a method of manufacturing an optical fiber base material including depositing soot generated by flame hydrolysis, the fluctuation band of the surface temperature of a burner fixing section including a burner holder and its fixture for burners for compounding the optical fiber base material is kept equal to or less than 80 degree C.The temperature can be controlled by a heat shield plate arranged between a burner flame and a burner fixing section and a temperature control mechanism that heats or cools the burner fixing section. Thereby the relative position between the burner and the soot deposition is stabilized, so that the manufacturing method being capable of manufacturing an optical fiber base material having a stable refractive index and the apparatus therefor can be provided.
