Abstract: A manifold apparatus includes a plurality of manifold blocks which are coupled together in a line. In each of the manifold blocks, an axial line of a branch port is deviated from an axial line of a main port in a direction perpendicular to a coupling direction in which the manifold blocks are coupled together. The plurality of manifold blocks are configured to be coupled together in a state where one of the adjacent manifold blocks is inverted 180° from the other of the adjacent manifold blocks in a direction perpendicular to the axial direction of the branch port and the coupling direction.

Abstract: When a ribbon is cast by heating raw materials to prepare a molten R-T-B-based alloy and supplying the molten alloy to a chill roll to solidify the molten alloy, the temperature of the molten alloy is adjusted in accordance with at least one of the arithmetic mean roughness Ra and the mean spacing of profile irregularities Sm of the surface of the chill roll, thereby controlling the spacing between adjacent R-rich phases in a crystal structure of resulting alloy flakes to a desired value. This makes it possible to inhibit variations in the crystal structure of the resulting alloy flakes that may occur due to wear of the chill roll. In adjusting the temperature of the molten alloy in accordance with at least one of the arithmetic mean roughness Ra and the mean spacing of profile irregularities Sm, it is preferred that the molten alloy temperature be adjusted using the equation: ?t=?7×(|?Ra|×|?Sm|)0.5/? where ?t is an amount of adjustment of the molten alloy temperature (° C.

Abstract: A method for producing an absolute alcohol containing not more than 0.4 mg/L of acetal by subjecting a raw material alcohol to a zeolite membrane treatment, the raw material alcohol being obtained by distilling a crude alcohol, and having an alcohol concentration of not less than 95 v/v%, and the raw material alcohol containing not more than 5 mg/L of acetaldehyde and not more than 60 mg/L of a total amount of organic impurities. An absolute alcohol can be produced, which absolute alcohol is highly safe to the human body and has a quality that no off-odor is felt by human senses. In addition, the contents of diacetyl and crotonaldehyde in the raw material alcohol may be set at levels not more than particular values, respectively.

Abstract: A cylindrical main body is provided with an inlet port and an outlet port. The outlet port is formed on a front end portion of the main body. A carriage is accommodated inside the cylindrical main body slidably in an axial direction of the main body. A sphere is held in the carriage such that a part thereof is exposed on a front end portion of the carriage. A carriage driver is provided for reciprocally moving the carriage inside the main body. A fluid flew into the main body from the inlet port stops flowing out from the outlet port when the sphere is abutted against the outlet port while the carriage is moved by the carriage driver toward the outlet port. The fluid starts flowing out from the outlet port when the sphere is separated from the outlet port while the carriage is moved away from the outlet port by the carriage driver.

Abstract: Disclosed are a method of and an apparatus for producing a heated recyled asphalt mixture, in which a new material and a normal-temperature waste material, the water content of which is set at a limited range of values, are adapted to be mixed together in the ratio of (90 to 40):(10 to 60) in terms of weight. The temperature of heating the new material by means of a dryer is controlled to range from 190.degree. C. to 350.degree. C. so as to be in conformity with the above mixing weight ratio. Both the materials are mixed and kneaded together in a mixer at a kneading temperature of 150.degree. C. or more. The gas generated within the mixer is exhausted toward a chimney in a state wherein the amount exhausted is made adjustable.

Abstract: Disclosed is a plant of batch system for producing a composite paving material by using a bituminous waste pavement material, which comprises a heating means equipped with a new aggregate material introduction shoot and a bituminous waste material introduction shoot, the former shoot being connected to a new aggregate material supply passageway and the latter shoot being connected to a reproduction material supply passageway. The plant also comprises a ratio control section which is intended to compare with each other respective supplying indicated values of new and waste aggregate materials as measured by conveyor scales disposed with respect to their corresponding supply passageways, and thereafter proportionally control the value of the waste material relative to the value of the new material so that both the values may bear a predetermined mixing ratio. The ratio control section, thereafter, generates a command control signal to an inverter involved in the waste material supply passageway.

Abstract: A process is provided for recovering a solvent vapor from a mixed gas of the solvent vapor and air. From a vessel storing a mixed gas of the solvent vapor and air, the mixed gas is passed through a compressor to be compressed to a low degree, the resultant compressed mixed gas is introduced to a first absorption column, where said compressed mixed gas is brought into contact with a first absorbent to absorb and recover a greater part of the solvent vapor. A gas coming out from the first absorption column is introduced to a second absorption column, where said gas is brought into contact with a second absorbent.
