Abstract: The purpose of the present invention is to provide a powder composition that can be used for cosmetics or skin topical agents and that replaces plastic powder bodies such as a nylon powder body, an acrylic powder body, and a urethane powder body. Provided is a composition which is a powder composition containing (a) acyllysine and (b) cellulose and/or starch, and which has a median diameter of the volume-based distribution of (A) acyllysine of 9 ?m or less. The contained amount of (A) is 2-40 mass %, and the contained amount of (B) is 3-95 mass %, with respect to 100 mass % of the total of the powder composition. The total amount of (A) and (B) is 10 mass % or more.

Abstract: The present invention provides a powder surface treatment method comprising (i) a step for mixing 0.001-20 parts by mass of a surface treating agent composition with 100 parts by mass of a power, and (ii) a step for adding an acidic liquid, followed by mixing, wherein the surface treating agent composition contains (a)-(d) below: (a) one or more selected from among an N-acyl amino acid having a carbon chain length of C8-C22 and a salt thereof; (b) one or more selected from among monohydric and polyhydric alcohols; (c) water; and (d) one or more selected from among (dl) an amino acid having an isoelectric point of 7.5-11, and (d2) a compound which generates an ion selected from among an aluminum ion, a magnesium ion, a calcium ion, a zinc ion, a zirconia ion, and a titanium ion, in the surface treating agent composition.

Abstract: A manufacturing apparatus of an electrical rotating machine includes a coil segment shaping section for shaping a linear wire rod with a predetermined length into a coil segment with a predetermined shape consisting of a pair of slot insertion portions extending substantially in parallel with each other and a linking portion for coupling the pair of slot insertion portions, and a coil assembling section for assembling a coil by circularly arranging the coil segments shaped in the coil segment shaping section. The coil segment shaping section and the coil assembling section are constituted to continuously perform the shaping and the assembling of the coil segment in each coil segment unit, based on control data set depending on a coil to be fabricated.
