摘要： PROBLEM TO BE SOLVED: To provide an operational speed reducer which maintains the effect of reducing the hitting noise level when a working shaft is abutted on a facing component for a long time, and also to provide an electromagnetically-driven valve using the operational speed reducer. SOLUTION: The operational speed reducer 54 used for the electromagnetically-driven valve comprises a first fitting part 41 mounted on an armature shaft (a working shaft) 21, a section fitting part 35 which is mounted on a valves stem (the facing component) 16 in the axial direction of the armature shaft 21, an expansion case 45 and an expansion elastic ring (a speed controller) 52. The expansion case 45 is formed of a rubber-like elastic material, one end thereof is fitted to the first fitting part 41, and the other end thereof is fitted to the second fitting part 35. The expansion case 45 seals a viscous fluid 50 interposed between the fitting parts 41 and 35. The expansion elastic ring 52 is disposed on the outer circumferential surface of the expansion case 45 to retard the expansion of the expansion case 45. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To maintain an effect of reducing collision sound when an operating part hits against an opposed part for a long time. SOLUTION: An operation speed reducing device 36 used in an electromagnetic drive valve reduces relative speed of an armature shaft 21 to a valve stem 16 as the armature shaft 21 (the operating part) and the valve stem 16 (the opposed part) relatively moving come close to each other. The operation speed reducing device 36 has a first mounting portion 37 attached to the armature shaft 21, a second mounting portion 41 attached to the valve stem 16 opposite to the first mounting portion 37, and an expandable case 44 made of metal bellows defining an sealed space 45 for filling viscous fluid between the mounting portions 37, 41. A speed reducing section comprising the expandable case 44 and the sealed space 45 is provided with an expandable means which is formed by filling the sealed space 45 with gas 47, expands and contracts according to pressure in the sealed space 45.

摘要： PROBLEM TO BE SOLVED: To provide an operation axis velocity reduction gear, for which the deceleration urging force is relatively large, even if it is a short distance through entire actuation of a device, and furthermore for which deceleration applied ability is relatively large. SOLUTION: The reduction gear is the operation axis velocity reduction gear 1, which makes the operating axis decelerate by means of a slide having an expanding diameter part by being fitted to the operating axis, which includes a smaller diameter part, as well as the expanding diameter gradually expanding from the end part of the small-diameter part and, includes balls 2 arranged around the small-diameter part of the operation axis, a received part 4 for rotatably holding the balls 2, and simultaneously and movably holding in the radial direction of the operating axis and an elastic holding means 5, which lies outside the balls 2 and which elastically biases toward center of axis of the operating axis by opposing to force, by which the balls 2 are moved in outside diameter direction by the expanding diameter part, and is set to the elastic holding means 5, so that the value of initial pressure on which the balls 2 are moved in the outside diameter direction by the expanding diameter part is opposed.

摘要： PROBLEM TO BE SOLVED: To reduce clearance between the outside diameter of a piston and the inside diameter of a cylinder by providing a circumferentially continuing slit in the head of the piston. SOLUTION: A thermal expansion absorption device 4 has an anchored part 41 anchored to the head 11 of a piston 1 and has a sealing part 42 extended to the outer periphery to dose a slit 15 and freely slidably and elastically brought into close contact with the upper end face 12a of a skirt 12. Thereby combustion gas is prevented from flowing out through the slit 15 and the route of heat radiation from the head 11 to the skirt 12 is secured whereby an expanding force generated by the thermal expansion of the head 11 held at high temperatures can be prevented from being transmitted to the skirt 11 which is relatively low in thermal expansion.

摘要： PURPOSE:To provide a method and device for testing fatigue by which fatigue data can be obtained in a short time and, at the same time, the cracking of a test piece due to fatigue can be surely recognized without requiring any visual inspection. CONSTITUTION:When a test piece 100 is made to resonate by giving vibrations caused by a loudspeaker 23 while one end of the test piece 100 is supported in the state of a cantilever, the amplitude of the test piece 100 decreases, because the characteristic frequency of the test piece 100 is deviated from the resonance point as the fatigue at the stress concentration part progresses. Therefore, the fatigue of the test piece can be detected when the amplitude of the test piece 100 is measured with a displacement measuring means 3.

摘要： PURPOSE:To make it possible to improve the pressure proof strength of a bellows main body easily by forming plural steel-made bellows single bodies in such a way that each part is formed continuously in the U shaped cross section and bent outward at its crest part by cutting work and butting only both peripheral end parts to be connected by welding, thus increasing the plate thickness of the single body without overlapping the steel of the same plate thickness. CONSTITUTION:In manufacturing a bellows main body 11, cutting work is applied to the steel 21 formed of a disc ring body so as to form a bellows single body 12. In this bellows single body 12, inner peripheral parts 13 which are to be the valley parts are continuously formed in the U shaped cross sections, and both peripheral end parts 14A, 14B which are to be the crest part are bent outward. Plural bellows single bodies 12 thus formed are adjoiningly disposed facing mutually in the axial direction X, and only the respective peripheral end parts 14A, 14B are butted to be connected by welding, thus obtaining the bellows main body 11.
