Abstract: A static fluid mixer which can perform processing such as generation of ultrafine uniform bubbles and has small pressure loss. A static fluid mixer has mixing units having outflow openings for allowing fluid having passed through mixing flow paths to flow through the outflow openings. The mixing units are arranged in a tubular casing body at intervals in the axis direction of the casing body. Adjacent mixing units and the casing body form a flow path forming space. Each mixing unit has an annular outflow path communicating with the end of each mixing flow path. The annular outflow path is open in a ring-like form having a substantially constant width along the entire circumference. The opening at the end of the annular outflow path functions as an outflow opening connecting to the flow path forming space.

Abstract: A reformed fuel oil capable of enhancing combustion efficiency. The reforming is performed by circulating a fuel oil required times through a primary reform treatment in which the fuel oil is caused to undergo not only flow by centrifugal force but also meandering flow made while repeating flow split and confluence in a direction crossing the direction of the centrifugal force flow and a secondary reform treatment in which the fuel oil having undergone the primary reform treatment is caused to undergo not only flow by pressure feed force but also meandering flow made while repeating flow split and confluence in a direction crossing the direction of the pressure feed force flow.

Abstract: An emulsion fuel is provided which is usable as a fuel for combusting an internal combustion engine under an appropriate combustion condition. A slight amount of air is added to, and is mixed with, a liquid mixture between a fuel oil as a continuous phase and water as a dispersed phase. In this manner, since air bubbles reduced in buoyancy is hydrophobic, the air bubbles do not adhere the surfaces of water droplets, and are dispersed in the fuel oil, increasing a gas-liquid interfacial area (combustion surface area) and exerting surface activity (similar to the function of a surfactant) due to electrostatic polarization. This makes it possible to prevent the coalescence of fine water droplets and stabilize the water droplets in the emulsion fuel.

Abstract: The present invention provides a method for analyzing gas components, an apparatus for separating the gas components, and a method for identifying the gas components that can provide more accurate information in distribution and consumption by classifying and identifying products that have been subjected to carbon monoxide treatment. The present invention provides a method for quantitatively analyzing gas components contained in a specimen, wherein an untreated specimen having an unchanged solid state and a prescribed weight is placed in an airtight container in which a solution is accommodated; the specimen is homogenized in the airtight container; and the gas components contained the specimen are quantitatively analyzed.
