摘要： PURPOSE:To sufficiently prevent loosening by actuating simultaneously in the circumferential direction and in the axial direction the force to prevent loosening between a bolt and a sleeve-shaped nut provided with a collar-shaped nut. CONSTITUTION:A nut 1 consists of an upper collar-shaped nut part 10 and a sleeve-shaped nut 11 in which an axial direction slit 13 unitedly formed so that mutual female screws 12 are connected and a tapered part 14 are formed. In the process threadingly fastening the nut 1 to a bolt 6, the inner circumference of a fastening member 3 comes in contact with the tapered part 14 of the sleeve-shaped nut 11 with interference left, and the sleeve-shaped nut 11 is gradually pressed against a shaft 60 of the bolt 6. When fastening is completed, the sleeve-shaped nut 11 is strongly pressed to the bolt shaft 60 and the elastic force of a coned disc spring 4 strongly acts in the axial direction on the nut 1 to stretch the nut 1. The turning of the bolt 6 is suppressed and force to stop loosening acts efficiently and continuously.

摘要： PURPOSE:To increase fastening force in connecting members and widen an applicable environmental temperature range by setting the ratio of a load in on-load to a load in off-load in the deflection in a spring test in a specified value or higher. CONSTITUTION:A cone disc spring is made of a Ni-Ti alloy comprising 50.7-51.2at.% Ni and the rest Ti or a Ni-Ti base alloy obtained by replacing part of Ni and/or Ti of the Ni-Ti alloy with 0.01-5.0at.% at least one metal selected from V, Cr, Fe, Co, and Nb and 0.01-10.0at.% Cu, and has superelastic effect. The cone disc spring having a disc shape H/h of 0.1-1.5 (H is cone disc spring height and h is cone disc spring plate thickness.) has the ratio of load P2 in off-load to load P1 in on-load, P2/P1, in 75% deflection of the maximum deflection of 0.35 or more in a spring test showing deflection in X axis and load in Y axis at normal temperature.

摘要： PURPOSE:To enhance the operation efficiency by causing a retainer metal fitting to be moved by the shape recovery force of the shape memory alloy up to a position where the retainer metal fitting contacts strongly the male screw inserted into an insertion hole of the fixing base in the fixing device for a machine tool, etc. CONSTITUTION:A fixing base 1 fixed to a structural material 10 is formed with an insertion hole 11 and is formed with a guide 12 in such a direction as to intersect the insertion hole 11 crosswise and in overlapping relation upon it. The insertion hole 11 is formed with an internal thread, into which an external thread 2 is screwed. A shaft-like shape memory alloy 3 is passed through the guide 12. An elastic member 5 consisting of a vinyl pipe and abutting against an inner flange 13 formed at one end of the guide 12 interior, and a retainer metal fitting 4 consisting of an iron pipe are axially movably mounted on the shape memory alloy 3 at one side thereof. A pipe-like spacer 32 abutting against the inner flange 13 is mounted on the shape memory alloy at the other side thereof while, on the other hand, stoppers 30, 31 are caulked thereto. By this construction, the retainer metal fitting 4 is linearly moved from its initial position to a position where one end thereof strongly contacts the surface of the male screw 2, thus fixing the same.

摘要： PURPOSE: To extremely reduce the inside and outside diameters of a small- diameter tube made of an NiTi based alloy for medical use, to clean the inside surface of the tube and to improve the production efficiency thereof by forming the tube to the respectively specific outside and inside diameters and specifically setting the thickness of the oxidized film on the inside surface of the tube. CONSTITUTION: An Ni-Ti alloy, etc., composed of Ni and Ti at about 1:1 by atom ratio are used as the material for tube stock and the tube is formed to the outside diameter of 0.2 to 2mm diameter and the inside diameter of 0.1 to 1mm diameter. As a result, the requirement for the smaller diameter for use and the hardness or ease of production are simultaneously satisfied. The thickness of the oxidized film on the inside surface of the tube is set at =1μm. The oxidized film of the outside surface of the tube is similarly required to be set at

摘要： PURPOSE:To provide a device which is capable of taking out the rotational output of a high speed from the rotational power of the specified speed, and capable of withstanding the drive of a subject of large inertia by connecting the respective terminals of a plurality of bodies of revolution by means of connecting springs, and respectively specifying the range of angles of the circular arc motion at the respective terminals. CONSTITUTION:A triangular cylinder display board 10 having three display surfaces 10a-10c are fixed to an axis of revolution 12 of a disc 11 which is the second body of revolution. The working angle is limited by bringing a protrusion 11a provided on the disc 11 into contact with the respective disc steps 14, 15. A pulley 16 which is the first body of revolution is fitted to the axis of revolution 12 to give rotation by the wound wire 17. Then, a tension spring 18 made of shape memory alloy and a bias tension spring 19 are attached to the wire 17, and at the same time, the respective application sleeves 20, 21 which limit the rotational angle of the pulley 16 to 180 degrees are mounted in contact with the respective wire stoppers 22, 23. The respective spring connecting terminals alpha, beta to the pulley 16 and the disc 11 are connected to each other by means of a connecting spring 24.
