Abstract: A crystal nucleating agent for polyolefin resins includes at least a raw material crystal nucleating agent (a) as a component (A), where the component (A) may be a diacetal compound. The crystal nucleating agent may have an angle of repose of 48° or smaller, and a 1-mm-thick polyolefin resin molded article produced using the crystal nucleating agent may have a haze value of 12 (percent) or smaller as determined by a method in conformity with JIS K7136 (2000). The crystal nucleating agent may be a blend including a sulfuric acid ester salt and/or a sulfonic acid salt as a component (E) and a higher fatty acid as a component (F). The blend may be obtained by preparing a mixture of the component (A) swelled with an organic solvent, the component (E) dissolved in the organic solvent, and the component (F) and removing the organic solvent from the mixture.

Abstract: A capacitance detection device includes a first electrode and a second electrode that at least partially face each other on opposite sides of a transfer path. An oscillator circuit forms an electric field between the first electrode and the second electrode. A detection circuit detects a change in capacitance between the first electrode and the second electrode. At least one of the oscillator circuit and the detection circuit is included in each of a first board and a second board. The first board is disposed such that a side surface of the first board faces the first electrode in an electric field direction, and the second board is disposed such that a side surface of the second board faces the second electrode in the electric field direction.
