Abstract: A mining riser pipe is extended from above water toward a water bottom containing water bottom resources, and a lower portion of an insertion pipe connected to a lower portion of the mining riser pipe is inserted into the water bottom. A liquid is supplied into the insertion pipe and a rotation shaft extends axially inside both of pipes is rotated to rotate stirring blades attached to a lower portion of the rotation shaft inside the insertion pipe, thereby drilling and dissolving mud S inside the insertion pipe into a slurry form is raised to an upper portion of the insertion pipe by a stirring flow generated by the rotation of the stirring blades, and the raised mud is lifted above the water through the mining riser pipe by lifting force.

Abstract: There is provided an electric junction box unit including: an electric junction box having a plurality of stud bolts; a plurality of electric wire with terminals each including a terminal and an electric wire and fastened to a corresponding one of the plurality of stud bolts; and a cover to which at least one of the plurality of electric wire with terminals is assembled. The electric junction box includes an interference portion that interferes with at least a part of the cover when the electric wire with terminals assembled to the cover are disposed at a position different from a normal position where one of the electric wire with terminals is fastened to the corresponding stud bolt.

Abstract: In the present invention, when a DC reactor is in a magnetically saturated state, the on/off operations of a switching element are suspended and the switching element is set to an off state for a predetermined period of time, thereby resetting the magnetic saturation of the DC reactor and maintaining the supply of power to a load. After resetting the magnetic saturation, the pulse output of the normal pulse mode is restarted.

Abstract: A vibration damper including a plate-shaped metal bracket having an attachment, and first and second extended parts extending from the attachment toward mutually opposite sides. Edge flanges rise from both widthwise edges of the attachment across its entire length. The first extended part includes the edge flanges extending continuously from the attachment and a pair of rising walls rising on both widthwise sides thereof. A first dynamic damper including a pair of support rubber elastic bodies and a mass member is provided between the rising walls. The second extended part includes a rising supporter rising from its end and the edge flanges being continuous with the attachment across its entire length including the rising supporter. A second dynamic damper including an inner shaft member and an outer mass member elastically connected by a main rubber elastic body is attached to the rising supporter.

Abstract: An object of the present invention is to provide an adhesive composition and an adhesive sheet that are stably dissolved or dispersed in a solvent or a dispersion medium having low polarity, have high total light transmittance and have high-function antistatic properties. An adhesive composition including (A) an adhesive polymer comprising repeated structures which consist of one or more kinds of (meth)acryl-based, urethane-based, silicone-based and polyolefin-based unit structures, (B) a conductive polymer complex including a conjugated polymer, and a polyanion having a block copolymer structure, and (C) a nonaqueous solvent or dispersion medium, in which the conductive polymer complex is contained by 0.1 parts by mass or higher and lower than 10 parts by mass relative to 100 parts by mass of the adhesive polymer.

Abstract: The toilet apparatus includes a main part and a toilet seat. The main part includes a case cover covering a function part and is attached on a toilet bowl. The toilet seat is attached rotatably to the case cover, and shifts between a closed state and an open state. The case cover includes an extending portion. A height becomes low toward forward. The toilet seat includes a toilet seat main body and a heating part. The toilet seat main body includes a first portion and a second portion. The first portion is positioned in front of the case cover in the closed state. The second portion rises backward from the first portion in the closed state, and overlaps the extending portion. An upper end surface of the extending portion changes to lower a height toward forward and to lower a height toward a side.
