摘要:
A method for manufacturing limonoid glucosides that is superior in terms of industrial productivity is described. The method includes a step in which a raw material composed of citrus juice and/or molasses is passed through a flow passage equipped with an adsorbent having limonoid glucoside adsorptivity, after which the limonoid glucosides that have been adsorbed by the adsorbent in the flow passage are eluted into a solvent using a solvent capable of dissolving the limonoid glucosides, which yields a liquid containing limonoid glucosides.

The invention discloses a bait for fishes and shellfishes characterized in that the bait comprises a matrix material containing a microorganically fermented product of a plant residue obtained by separating from a plant at least one liquid selected from the group consisting of vegetable juice, fruit juice, plant essential oil, juice extracted from a processed plant product, plant milk and mixtures thereof, or disintegrated product of said microorganically fermented product, wherein the matrix material has incorporated therein (A) an amino acid having 2 or 3 carbon atoms, and (B) amino acid having at least 4 carbon atoms in an (A)/(B) molar ratio of 1:1 to 40:1.
摘要:
A manufacturing method of case-hardened parts whose chemical components comprising especially Fe, C, Si, Mn, S, Ni, Mo, Al, V and N including a step of the heat treatment 1 in which, after carburizing, carbonitriding or carburizing followed by carbonitriding steel is cooled gradually at a temperature less than 100.degree. C./minute, by another step of the heat treatment 2, in which steel is heated to a temperature higher than the Ac.sub.3 transformation point and less than 850.degree. C. and kept at the above temperature before quenching, or after keeping at the temperature, is cooled down to a level not below 600.degree. C. before quenching, or quenching is done after cooling down to and keeping the temperature not below 600.degree. C. is disclosed. This method makes the surface layer a mixture of martensite and retained austenite. Thus the case hardened steel products of high precision and high strength are obtainable.
