Abstract: PURPOSE: To mass-produce a bolt at a low price and to reduce the engaging resistance by providing a surface of a threaded shank ranging form its underhead part to its shank-end, with a groove-like flowing passage and forming a top of an end of arched surface, which faces the grooved flowing passage of thread ridges, into a convex, curved surface. CONSTITUTION: A shank 2 consists of an under-head part 21 having a prescribed length and a threaded shank 22, on which thread ridges are formed. A plurality of groove-like flowing passages reaching the shank-end are formed on the outer surface of the shank 2 at an equal interval. The top part of an arched end-surface 32, which becomes a break of the thread ridge and which faces the groove-like flowing passage 3, is formed into a convex, curved surface 33.  In manufacturing the bolt, either the groove-like passages are formed by plastic working or by cutting working on the surface of the shank 2 of a bolt-blank, on which no thread ridge is formed, in such a manner that the periphery of the shank 2 is divided into equal parts, or the flowing passages 3 are formed during the time of pressure rolling to the bolt blank first, and then the threaded shank is manufactured through (tread-)rolling by using three sets of thread rolling machines arranged at an equal interval, centering around the shank 2. Accordingly, the flowing passage 3 can be formed easily and accurately, the engaging resistance can be reduced, and a possibility of producing chips, which is caused when a soft member to be fastened is cut off by a large engaging resistance, can be eliminated.

Abstract: PURPOSE: To reduce the desulfurization cost and prevent accidents such as powdery dust explosion, by dividing the outside and inside of the cylindrical cage into five zones of adsorption, heating, desorption, cooling, and adsorbent exchange zones by the casing and seal devices.  
     CONSTITUTION: Gas to be treated enters from inlet 10 and passes through the charged layer of rotary cage 1 and is emitted from outlet 11. The adsorbent of the charged layer of rotary cage 1 adsorbs sulfur oxides from gas to be treated during one rotation in adsorption zone (a) and is heated up to the temperature adapted to desorption in heating zone (b). Next, in desorption zone (c), adsorbed snlfur oxides are released by desorptive gas, and desorptive gas containing sulfur oxides is sent to the sulfur components collector from outlet 13. The adsorbent after desorption is cooled by cooling zone (d) and enters into adsorption zone (a) again. The adsorbent which was used 5W15 times to degrade performance is pulled out, and a new adsorbent is supplied from supply tank 14 in adsorbent exchange zone (e), thus preventing degradation of performance.
