摘要： PURPOSE: To add an adequate rate of upsetting after welding and obtain a stable weld zone by making the sum of the lengths on the opening sides of a square pipe blank material which is corner bent by roll forming longer by the length expressed by the prescribed equation.
CONSTITUTION: A steel strip is fed into top corner bending rolls 7, and is bent by leaving lengths l
1 , l
2 of opening sides in such a way as to provide the lengths on the top side of a square pipe when joints are welded. At this time, the sum of the lengths l
1 , l
2 on the opening sides is made longer by the length S expressed by the equation with respect to the lengths on the sides opposite from said opening sides. Next, a blank material 9 goes through lower side bending rolls and is fed to fin pass rolls 13, by which it is subjected to corner bending to a roughly square shape. Thence, the top side opening ends are butted and electrically welded by welding rolls 14, whereby a steel shape of a square shape having a welded joint 15 on the top side is obtained.

摘要： PROBLEM TO BE SOLVED: To provide an ice making vessel having improved efficiency of making ice with cold air and being lighter and strong, easy to assemble/disassemble, simple and efficient to transport and size changeable, and a heat exchange pipe having simple and inexpensive construction.
SOLUTION: The ice making vessel utilizing cold air comprises a grooved body in a grooved shape having corrugations perpendicular to the grooving direction and a water stop plate for blocking the grooved body at both side edges, the grooved body and the water stop plate being bolted to each other. A heat exchanger pipe which is opened at both ends and has a downward curved portion and approximately horizontal portions at both ends is placed thereon. Otherwise, a heat exchange pipe is provided thereon which is raised from the inside bottom of the vessel up to a level near the upper end of the vessel and vertically opened at both ends.

摘要： PURPOSE:To facilitate the position adjusting of roll position changing rolls through oscillating of the rolls during running, by providing forming rolls at the two vertexes of triangular oscillating plates and mounting the other vertex freely oscillatably to the right and left roll stands. CONSTITUTION:Shafts 2 are provided to the blocks 5, 6 which are provided horizontally slidably to upper and lower stand beams 3, 4 in the positions of the lateral symmetry with respect to the centerlines C, C of the roll stand. Next, the shafts 2 are made vertically movable by means of their nuts 7 and keys 8 without being rotated. In addition, rolls 14, 15 are mounted to the shafts 12, 13 at the other two vertexes of upper and lower triangular oscillating plates 11 peaking at the position of the shafts 2. Next, if a forming material 16 is pushed between the rolls 14 and 14, the oscillating plates 11 rotate in such a manner as to expand the space between the right and left rolls 14. Thence, when the forming material 16 is bitten in the rolls 15, the rolls 15 receive outward force and the oscillating plates 11 rotate in such a manner as to narrow the rolls 14. Then, the rolls 14, 14 and 15, 15 exert forming force to the forming material.

摘要： PURPOSE:To provide the titled bead removing device enabling to remove beads efficiently with gathering O2 gas from the bead side part to a bead part, by directing two pieces of scarfing nozzles for close to a sean welding position and by arranging symmetrically on a seam both scarfing nozzles. CONSTITUTION:An electric welded tube 1 is produced by forming a skelp in circular shape and performing an electric resistance welding by pressing by a squeese roll so as to abut both edges 5, while O2 gas is spouted from a scarfing nozzle 9 and auxiliary heating nozzle 13 by feeding a pressurized O2 to an oxygen conduit pipe 7 and 13. The O2 gas jetted from the nozzle 9 is flowed toward the seam along the inner peripheral face of the pipe 1 from the side part of the bead 6 and removes excess bead 6 by blowing off with oxidation the high temp. bead 6. Because of the O2 gas flowing so as to gather to the bead part at this moment, the O2 gas acts without waste on the bead removal and removes the bead 6 easily due to its high density. The O2 gas sprayed on the head 6 is directed for the upstream side and diffused in the air from an open pipe 2.
摘要翻译：目的：提供标题珠去除装置，能够通过将二氧化碳气体从珠边部分收集到珠粒部分，从而有效地除去珠粒，通过将两片切割喷嘴引导到接近an焊位置并对称地布置在接缝上烧烤喷嘴。构成：电焊管1通过形成圆形的骨架并通过压制辊进行电阻焊接，以便邻接两个边缘5，同时从熔化喷嘴9和辅助加热喷嘴喷出O 2气体通过将氧气导管7和13供给加压的O 2，从喷嘴9喷出的O 2气体沿着管子1的内周面从胎圈6的侧部流向接缝，并且去除多余的胎圈6 通过吹脱氧化高温。由于O 2气体在此时流动以便聚集到胎圈部分，所以O 2气体在珠粒移除时没有浪费，并且由于其高密度而容易地去除胎圈6。喷射在头6上的O2气体被引导到上游侧并且从开口管2扩散到空气中。

摘要： PURPOSE:To make the displacement of a measured body proportional to the change in an output, by placing the light reception face of a position detector so that the face coincides with the loci of a light spot image on the measured body, which take place when the body is displaced. CONSTITUTION:A light beam from a light source 1 is converged into a thin irradiated light beam 3 by an irradiation lens 2. The thin beam is projected to a measured body 4 in parallel with its displacement to be measured. Reflected light 3' from the body 4 is received by a condensing lens 5 in a direction different from that of proceeding of the beam 3 to form a light spot image on a light receiver 7 in a position detector 6. The receiver 7 is so placed that the loci of the light spot image coincide with the light reception face of the receiver. The ratio between both photoelectric (currents) i1, i2 of the light receiver changes depending on the position of the light spot image. The position y of the light spot image is determined by a calculator 8. The output of the calculator is applied to a compensation circuit 9 to perform compensation to make the displacement x of the body 4 and the output of the calculator 8 proportional to each other.
