The plug member includes: a plug portion for sealing the supply port; a cover portion formed integrally with the plug portion; a pinch portion including a first portion and a second portion provided on the cover portion and opposite to each other; and a hollow portion extending from the cover portion through the plug portion. The plug portion and the cover portion are made of an elastic body, and the hollow portion has an opening on the cover portion side. A width of the opening is narrowed and a side face of the plug portion is deformed toward the hollow portion by pinching the first and second portions.

Abstract: In a server that predicts, as a contract price, a price of a purchase target to be provided by a supplier to a buyer, a reference setting unit sets a reference price based on an actual price of the purchase target currently or previously provided by one or more suppliers to the buyer. A purchase requirements setting unit sets purchase requirements including at least a purchase volume of the purchase target in the buyer, which are necessary for estimating a price of the purchase target to be provided to the buyer. A buyer requirements setting unit sets requirements regarding the buyer, which serve as buyer requirements including at least credit strength of the buyer. A prediction unit predicts the contract price based on the reference price, the purchase requirements, and the buyer requirements.

Abstract: The bushing includes an outer cylinder, an inner cylinder, and an elastic body therebetween. The outer cylinder has a central recess portion formed in a curved shape. The inner cylinder has a central convex portion being formed in a curved shape. A distance between a vertex of the central recess portion and the vertex of the central convex portion is smaller than a distance between a point other than the vertex of the central recess portion and a point at which a straight line extending from the point other than the vertex of the central recess portion to an intersection point of the perpendicular line and the axis of the inner cylinder intersects the central convex portion.

The outer cylinder has a central recess portion recessed from the inner peripheral surface in the radial direction at the central portion in the axial direction, and the thickness of both end portions is thicker than the thickness of the central portion. The central recess portion is formed in a curved shape or having a curved and a straight shape. The inner cylinder has a central convex portion swelling from the outer peripheral surface in the radial direction at a position corresponding to the central recess portion. The maximum outer diameter of the central convex portion is larger than the minimum inner diameter of the inner peripheral surface of the outer cylinder.

Abstract: A center console structure includes a metal internal frame that supports a shift operation mechanism, and an outer sheath body made of resin that encloses the internal frame and forms a dressed surface. A front side part of the internal frame is slanted so that an upper member is positioned forward and obliquely upward of a base part member closer to the floor surface, and a storage part is formed in front of the base part member in which a bottom part extending in a vehicle front-rear direction to a position immediately below an instrument panel is provided. Both left and right side walls of the bottom part are surrounded by left and right fence parts formed by extending lower parts of left and right side wall parts of the outer sheath body forward, a rear part is surrounded by a front lower part of the outer sheath body.

Abstract: There is provided a power amplifier capable of readily reducing odd-order harmonic waves even in high frequencies. This power amplifier includes n current sources (where “n” is a natural number equal to or greater than 3) that cause predetermined currents to flow; n switches that open and close current paths of the n current sources, respectively; and a signal generating section that generates n timing signals for turning on/off the n switches, respectively. In the power amplifier, the n timing signals are signals that have an identical duty ratio and that are different in phase; and the power amplifier outputs a signal amplified in power based on the currents flowing through the n current sources.
