Abstract: An electrode system which includes: an electrode unit capable of switching at least a part of its shape between a curved shape and a stretched shape, wherein in the curved shape the electrode unit is wound around a predetermined linear tissue, and wherein in the stretched shape the electrode unit is flat; and a treatment tool that switches the shape of the at least a part of the electrode unit between the curved shape and the stretched shape, wherein the electrode unit includes: an insulating member formed in a sheet shape out of an elastic material; and an electrode that is disposed on a first surface which is an inside surface of a curvature when the insulating member has a curved shape and which applies a predetermined voltage.

Abstract: An intermediate shaft is provided which connects a steering shaft and a steering gear mechanism together via a universal joint, a shoulder bolt is provided which fastens one of yokes of the universal joint and a shaft portion of the intermediate shaft and on which a small diameter portion and a large diameter portion which are adapted to be brought into engagement with an outer circumferential surface of the shaft portion are formed sequentially from a distal end portion side, and the intermediate shaft has a bolt engagement recess portion which is formed on an outer circumferential surface of the shaft portion in such a manner as to extend in a direction which intersects an axial direction and which is adapted to be brought into engagement with the large diameter portion of the shoulder bolt and a dislocation preventive projecting portion which is formed on an outer circumferential surface of an end portion thereof, whereby a temporary fastening is implemented by bringing the small diameter portion of the sh

Abstract: A ceiling board free from trouble due to bending is to be provided. In the ceiling board to be supported horizontally by its peripheral parts as fixed parts, the part between the fixed parts, in a state wherein it is bent by its own weight, is formed in a dome shape in a direction reverse to the direction of bending by the part's own weight so that the board surface be horizontal.

Abstract: For the purpose of providing an RF coil that prevents a troublesome force from arising when a hanging portion is lifted up, a pair of handhold members 308 is provided along a side that corresponds to an inner side of a cylinder 110, each member extending from one end to the other end of one of a pair of flexible substrates 304 so that an operator can lift the hanging portion up using such handhold member.
