    Abstract: An electronic component manufacturing method includes a blotting process of bringing a conductive paste applied to an end portion of each electronic component body held by a jig into contact with a surface of a surface plate. The blotting process includes simultaneous performance of a distance changing process of changing the distance between an end face of each electronic component body and the surface of the surface plate and a position changing process of changing a two-dimensional position where the end face of the electronic component body is projected on the surface of the surface plate in such a manner that the direction of the movement of two-dimensional position in parallel to the surface of the surface plate successively varies (e.g., along a circular path).

    Abstract: A method of producing a substrate includes: applying a composition on a metal basal plate to form a coating film; and forming a metal-containing layer on at least a part of the coating film. The composition contains a solvent, and a polymer having a first terminal structure and a second terminal structure in a single molecule. Each of the first terminal structure and the second terminal structure is at least one selected from the group consisting of a structure represented by formula (1) and a structure represented by formula (2). A1 and A2 each independently represent a monovalent group having a functional group capable of forming a chemical bond with a metal atom. L2 represents —S—, —NR—, or —NA22-, wherein A22 represents a monovalent group having a functional group capable of forming a chemical bond with a metal atom.

    Abstract: The preparation method of a starch-based double-loaded functional nanoparticle includes: performing restrictive hydrolysis treatment on egg high-density lipoprotein using proteases to obtain the polypeptide; performing self-assembling on a mixed system containing the polypeptide and quercetin under the alkaline condition to form a micelle nanoparticle; performing covalent grafting reaction on a mixed system containing the micelle nanoparticle and anthocyanin under the alkaline condition to form a graft; and electrostatically compounding carboxymethyl dextrin with the graft to obtain the starch-based double-loaded functional nanoparticle. In the preparation method, raw materials derived from natural sources are used, and the self-assembled colloid nanoparticle with good properties can be obtained by adjusting the pH without any organic reagents. The obtained product has a nanoparticle size, has high antioxidant activity and stability against environmental stress, and can be widely applied to the fields of delivery of nutrients, stabilization of biologically active substances and the like.

    Abstract: A coating film forming method includes: rotating a substrate at a first rotation speed in a coating cup with an upper surface open, and supplying and diffusing a coating solution for forming a coating film on the substrate; and after the supplying and diffusing the coating solution, drying the substrate by exhausting air through a gap between an annular member arranged above the substrate with centers thereof being located on a same axis and the front surface of the substrate, while rotating the substrate at a second rotation speed lower than the first rotation speed, wherein at the drying the substrate, a flow velocity of the air exhausted through the gap is higher than a flow velocity of air supplied from above the substrate in the coating cup to the substrate.
