Abstract:
A treatment device for endoscope includes a flexible sheath, an operation wire that is advanceably/retreatably inserted into the sheath, a treatment part comprising at least one elastic wires that can enter and exit a tip side inner part of the sheath, and a connecting member that secures to each other a tip of the operation wire and ends of the elastic wires. The connecting member includes a cylindrical body part, and a plurality of walls that extend from one end face of the body part in the direction of the axis of the body unit. A proximal end of the operation wire is secured to the body part, and the plurality of ends of the elastic wires are secured to the wall in the direction of the axis; when viewed from the wall side in the direction of the axis, at least one of the ends of the elastic wires overlaps with the body part. The interval between mutually adjacent walls is narrower than the outer diameter of the elastic wires.
Abstract:
A high-frequency treatment tool (1) includes an operating wire (12) having a treatment part (10) including a treatment electrode; a first tube (23) formed from an insulating material, in which the operating wire (12) for enabling the treatment part (10) to protrude and recede is inserted; and a second tube (21) having a passive electrode (22) at a distal end, in which inserted the first tube (23) such as to cover an inner peripheral face of the passive electrode (22) is inserted. An engagement part (25) and an engaged part (22C) that can engage with each other are formed in the first tube (23) and the passive electrode (22), and the engagement of the engagement part (25) with the engaged part (22C) restricts the relative movement of a distal-end part of the first tube (23) to a proximal-end side of the first tube (23) with respect to the passive electrode (22).

Abstract:
The present invention provides a β-type titanium alloy keeping the content of the relatively expensive β-stabilizing elements such as V or Mo down to a total of 10 mass % or less and reducing the effects of composition segregation of Fe and Cr and thereby able to keep the Young's modulus and density relatively low. The β-type titanium alloy of the present invention comprises, by mass %, when Al: 2 to 5%, 1) Fe: 2 to 4%, Cr: 6.2 to 11%, and V: 4 to 10%, 2) Fe: 2 to 4%, Cr: 5 to 11%, and Mo: 4 to 10%, or 3) Fe: 2 to 4%, Cr: 5.5 to 11%, and Mo+V (total of Mo and V): 4 to 10% in range, and a balance of substantially Ti. These include Zr added in amounts of 1 to 4 mass %. Furthermore, by making the oxygen equivalent Q 0.15 to 0.30 or leaving the alloy in the work hardened state or by applying both, the tensile strength before aging heat treatment can be further increased. Due to this, it is possible to obtain the required strength even if the amount of precipitation of the α phase with the high Young's modulus is small.

Abstract:
An α+β-type titanium alloy which, has a high Young's modulus and strength-ductility balance is provided as a material for a face of a driver, iron, or other golf club.A titanium alloy having a high strength and high Young's modulus for a golf club face comprising, by mass %, 4.7 to 5.5% of Al, 0.5 to 1.4% of Fe, 0.03% or less of N, O which satisfies an [O] eq (oxygen equivalent value) of 0.25 to 0.34% calculated by formula (1), and a balance of Ti and unavoidable impurities. By adding Al, O, and N which cause solution strengthening of the α-phase and selecting the inexpensive Fe as the β-stabilizing element and suitably limiting the amounts of addition of these elements, it is possible to achieve a high strength and a high Young's modulus which satisfies the SLE rule without relying on cold working strengthening or aging strengthening heat treatment, and simultaneously obtain a large, good total elongation and a high strength-ductility balance. [O]eq=[O]+2.77[N] formula (1)

There is also provided a fixing structure of the bus ring configured such that an insulator is interposed between each of the stator teeth and the winding protruding in the axial direction from the end face of the stator to enter inside the conductive wire of the bus ring.
Abstract:
The present invention provides, as a material for a golf club face of a driver, an iron or the like, a titanium alloy which satisfies the regulation for a coefficient of restitution, and has high Young's modulus and tensile strength and also has excellent hot and cold workability. The titanium alloy for a golf club face according to the present invention comprises, in percent by mass, 1.0 to 3.5% of Al, 0.5 to 1.4% of Fe, 0.2 to 0.5% or O and 0.002 to 0.030% of N, and the balance of Ti with inevitable impurities, wherein an α-phase is strengthened by combined addition of O and Al, and inexpensive Fe is selected as a β-phase stabilizing element, leading to high strength and high Young's modulus in combination. The content of Al causing deterioration of hot workability is limited to a low value, leading to low rolling load during hot rolling, and thus flaws and edge cracking are unlikely to occur during hot rolling.
