Abstract: A substance capable of stimulating the movement of digestive tract, comprising a compound of the formula: (I) (active substance ? and active substance ? being stereoisomers), which substance is derived from natural products and hence cause no side effects, is highly safe even when continuously used for a prolonged period of time and can be widely employed as additives to refreshments, etc.; and a refreshment containing an additive comprising the stimulating substance. In particular, a digestive tract movement stimulating substance capable of acting on muscarine M3 receptor, obtained from beer through isolation and purification, which substance is one having drinkability stimulating effect; and a composition from natural products or natural processed products, comprising the above substance. The thus provided substance or composition is used as an additive to refreshment, thereby providing a refreshment capable of stimulating the movement of digestive tract.

Abstract: A method for producing a multilayer printed wiring board by the buildup process. A first layer printed wiring pattern (13) is formed on a metal core (11) over a first insulating laminate (12), and second layer printed wiring pattern (16) is formed on the first layer printed wiring pattern over through studs (15) and a second insulating laminate (14). The surface of the first layer printed wiring pattern (13) is roughened and the through studs (15) are formed by the buildup process using a conductive paste on the roughened surface.

Abstract: A process for manufacturing a polyester resin insulated wire involves coating a resin consisting essentially of a saturated substantially linear polyester resin prepared by reacting (i) an aromatic dicarboxylic acid or a dicarboxylic acid in which an aliphatic dicarboxylic acid is substituted for part of the aromatic dicarboxylic acid, and (ii) an aliphatic diol or an aromatic diol on a conductor having a copper surface without use of a solvent, and then heating the coated conductor in oxygen or an oxygen-containing gas at a temperature higher than the melting point of said linear polyester resin to permit cross-linking in the coated resin.

Abstract: A process for crosslinking a polycarbonate resin involves heating the polycarbonate resin in the presence of an organic copper compound at a temperature higher than the glass transition point of the polycarbonate resin.

Abstract: Copper powder or a copper compound is mixed with a substantially linear polyester series resin, and the resultant resin composition is formed into a predetermined shape. Thereafter, the resin composition is heated to a temperature above the melting point of the resin in an oxygen-containing atmosphere for cross-linking the polyester series resin.
