Publication number: 20160057303Abstract: A main power source portion generates a primary DC power from an input AC power, and a first sub power source portion generates a power source control secondary DC power from the primary DC power. Each of a plurality of second sub power source portions, upon input of an activation signal, generates an equipment secondary DC power from the primary DC power. A sub-power-source control portion starts to operate upon receiving the power source control secondary DC power. The sub-power-source control portion outputs the activation signal to a display-related second sub power source portion with higher priority when the detection result of a power state detection portion satisfies a predetermined unfavorable condition, than when the detection result does not satisfy the unfavorable condition, and outputs an alarm signal to cause display-related equipment to output an alarm.Type: ApplicationFiled: August 18, 2015Publication date: February 25, 2016Inventor: Hiroyuki Fujita

Publication number: 20160011163Abstract: The interior of a fractionating tool for fractionating dioxins is packed with a purification layer and an adsorption layer. The adsorption layer includes a first adsorption layer including an activated carbon-containing silica gel layer and a graphite-containing silica gel layer, and a second adsorption layer including an alumina layer. When a solution of dioxins is injected into the purification layer and is supplied with an aliphatic hydrocarbon solvent, the solvent dissolves dioxins in the solution of dioxins and passes through the purification layer and the adsorption layer. In this process, non-ortho PCBs, PCDDs and PCDFs among dioxins are adsorbed to the first adsorption layer, and mono-ortho PCBs among dioxins are adsorbed to the second adsorption layer. As a result, dioxins are fractionated into a group including non-ortho PCBs, PCDDs and PCDFs, and mono-ortho PCBs.Type: ApplicationFiled: May 27, 2013Publication date: January 14, 2016Applicant: MIURA CO., LTD.Inventors: Hiroyuki FUJITA, Hirofumi NAKAMURA

Publication number: 20160003784Abstract: A solute trapping column including two trapping agent layers has a first branched pathway extending from an upper part of a main body part thereof, and a second branched pathway extending from between two trapping agent layers, and with its upper part a purification column is connected. By injection of solution of dioxins and supply of solvent into the purification column, dioxins are trapped by the trapping agent layers. An extraction solvent supplied from the lower end side of the solute trapping column while keeping both the purification column and the first branched pathway blocked extracts the dioxins trapped by the second trapping agent layer and flows into the second branched pathway. An extraction solvent supplied in a similar manner while keeping both the purification column and the second branched pathway blocked extracts the dioxins trapped by the first trapping agent layer and flows into the first branched pathway.Type: ApplicationFiled: August 23, 2013Publication date: January 7, 2016Applicant: MIURA CO., LTD.Inventors: Hiroyuki FUJITA, Hirofumi NAKAMURA
