Described herein is a floating flap gate including a gate leaf having a buoyancy forming portion, the gate leaf being configured to be raised due to buoyancy effect (e.g., from water), a bottom fitting mounted to a proximal end portion of the gate leaf, the bottom fitting having a convex circular arc-shaped surface across a width direction of the gate leaf, a plate member having a concave circular arc-shaped surface to be mated with the convex circular arc-shaped surface of the bottom fitting when the gate leaf is in a lowered state, wherein the concave circular arc-shaped surface is in contact with the convex circular arc-shaped surface when the gate leaf is raised.

Floating flap gate

An aggregate of functional particles includes a plurality of functional particles and an insulating material for covering the plurality of functional particles, and a large number of aggregates of functional particles are filled in a resin. Alternatively, insulating functional particles are added to the plurality of functional particles by an amount less than 50% of that of the functional particles in volume ratio.

Composition of a functional material, and method of and apparatus for producing same

Magnetic powder contained in a resin composition for use in injection molding is coated with an insulating material, and a soft magnetic green compact or a hard magnetic green compact is insert molded into the resin composition. Increased magnetic flux destiny, reduced size, a simplified shape, and/or increased filling density can be achieved in a core part of an electric instrument.
