Abstract: A gas-insulated switchgear includes a main circuit conductor forming a bus line, a tank having a tubular main body in which the main circuit conductor forming the bus line is provided at its center, and a grounding-switch tank that is a branch pipe connected to the main body, in which a movable contact forming a branch line that branches from the main circuit conductor forming the bus line is provided, where a tubular surface of the main body is spherical, and has an opening that allows the movable contact to pass therethrough.

Abstract: A gas-insulated switchgear includes: a plurality of circuit breakers extending along a first direction and aligned in rows along a second direction perpendicular to the first direction; one end rising portions raised from one end of the plurality of circuit breakers along a third direction perpendicular to the first direction and the second direction; other end rising portions raised from another end of the plurality of circuit breakers along the third direction; and a plurality of connection busbars connecting the other end rising portions together or connecting the one end rising portions together. Two lines through which the connection busbars pass are set between the one end rising portions and the other end rising portions.

Abstract: A switchgear includes a first contact capable of reciprocating along a motion axis, and a second contact. The second contact includes a facing unit movable in a first direction from the first contact toward the second contact when the facing unit is pushed in by the first contact, a spaced unit spaced from the axis and urged in a direction toward the axis, and a regulating unit coupled to the facing unit. The spaced unit abuts on the regulating unit to restrict movement of the spaced unit in the direction toward the axis as the facing unit is located in the second direction. The spaced unit is released from abutment on the regulating unit to move in the direction toward the axis into abutment on the first contact as the facing unit moves in the first direction.

Abstract: A polyester resin composition containing a polyester resin, and a fine cellulose fiber composite having an average fiber diameter of from 0.1 to 200 nm, wherein the fine cellulose fiber composite contains fine cellulose fibers and hydrocarbon groups being connected thereto via an amide bond. The polyester resin composition of the present invention can be worked into a molded article by thermoforming or injection-molding, and is suitably used for various industrial applications, such as daily sundries, household electric appliance parts, packaging materials for household electric appliance parts, and automobile parts. In addition, the fine cellulose fiber composite has high dispersibility against various resins and can exhibit thickening effects, so that it is suitable as various thickeners or the like.
