摘要： PROBLEM TO BE SOLVED: To make it possible to cut a rod-like article and to polish its cut surface in the step while holding the article such as a concrete specimen under test by simple holding means. SOLUTION: Holding means for engaging a rod-like article S with a holding cutout part 22 formed in the radial direction of a disc 21 and bringing a tension belt 31 into close contact to rotatable hold the article S is provided. A pair of cutters 50 for cutting the held article S by a peripheral blade 52 by rotating are disposed at a suitable interval. Polishing units G for polishing the cut surface of the article S are provided by slightly protruding in the lengthwise direction of the rotary shaft 42 of the cutters 50 from the blade 52 at the opposed surfaces of the cutters 50.

摘要： PROBLEM TO BE SOLVED: To provide a practical press-application observation device enabling the observation of a test material while giving stress to the test material in a closed chamber such as a vacuum or a gaseous atmosphere under temperature control. SOLUTION: The stress-application observation device is provided with a furnace body 61 equipped with an observation window for observing a test material 3 disposed in a furnace chamber 62, a high temperature observation furnace 60 having a suction port 68 for reducing a pressure in a heater 64 and the furnace chamber 62, and a tensile tester 30 capable of giving at least tensile strength to the test material 3 by displacing a pair of cross heads 31, 32 in an opposite direction each other by the same distance. Vacuum seals 49, 72 permitting a relative movement along a movement direction of the cross heads 31, 32 are provided between connection bodies 45, 46 interposed between the cross heads 31, 32 and the test terminal 3 and the high temperature observation furnace 60 respectively.

摘要： PROBLEM TO BE SOLVED: To provide a clamping device of screw type reinforcement joints which securely holds reinforcements although it is simple in the constitution and relatively rotates to sufficiently clamp the reinforcements and the sleeve and which can hold the reinforcements, even if the diameter thereof is a little different from each other. SOLUTION: A reinforcement 100 in which a screw is cut 100a at the end and a sleeve 101 are screwed and clamped together. The first divided body 10 fixed to the sleeve 101 and the second divided part 20 holding the reinforcement 100 are connected to each other so as to be relatively rotatable around the center axis P and a clamping structure 40 is provided to relatively rotate the first and second divided bodies 10, 20. The holding structure 30 holding the reinforcement 100 in the second divided body 20 is provided with a pair of pivot shafts 22, 22 arranged parallelly to the center axis P, four movable pieces 31, 32 movably supported by these pivot shafts, and a drawing tool 34 for the mutual movable pieces 31, 32 oppositely arranged so as to set closely the contact part provided in the movable pieces 31, 32 to approach the reinforcement 100.
