Title: Diffusion joining method of ti
Inventor: WACHI HIROSHI
IPC: B23K35/00
Filed: 1983-06-08
Abstract: PURPOSE:To reduce the time for treatment and to prevent deformation of a material to be joined having a low melting alloy layer and a material to be joined having no alloy layer by placing both materials to be joined so as to face a joint surface and joining the same. CONSTITUTION:Powder formed by incorporating Si, Cr and B into Ni base is used for the purpose of forming a low melting alloy layer on the joint surface of a material to be joined. The formation of the low melting alloy layer is accomplished by sticking the powder to the joint surface of the material to be joined by means of a binder and irradiating the same by a laser irradiation method in an Ar atmosphere to form the alloy layer. The surface of the alloy layer, that is, the part to be used as the joint surface, is flattened by emery paper. The joining is accomplished by setting the materials to be joined in a non-oxidizing atmosphere, pressurizing the materials simultaneously with heating and holding the materials for a prescribed time.

Title: Arc stabilizing method for inside pipe surface welding
Inventor: ISHIKAWA YASUSHI
IPC: B23K9/08
Filed: 1980-07-25
Abstract: PURPOSE: To stabilize an arc and to display its effect sufficiently by selecting the shape and arrangement of magnetic poles of electromagnets when welding the inside surface of a thick pipe by two DC electrodes.  
     CONSTITUTION: Magnetic poles 4a and 4b of an electromagnet 3 as the 1st electrode are increased in area where a base material 2 faces, and set parallel to the base material 2 at a distance l 1  which is short, but causes no trouble in welding operation; and the surface of the electromagnet 3 facing to the base material 2 is put as  close to an arc as possible. When the electromagnet 3 is energized with the opposite  polarity to that of the base material 2, a line 9 of magnetic force flows and a crossing magnetic field is produced in an edge part 1 to stabilize the arc. The parts of  magnetic poles 14a and 14b of an electromagnet 13 as the 2nd electrode facing to  the base material 2 is made small in area, and a distance l 2  between the magnetic  poles 14a and 14b, and the base material 2 is made relatively large. Since a weld  bead 10 as the 1st layer is formed in the edge part 1, an arc from the electrode 18  flies near the surface of the base material 2. Consequently, an arc for the welding of  the 2nd layer is regulated by a line 19 of magnetic force to be stabilized.

Abstract: PURPOSE:To manufacture easily a plug member which is rich in chemical resistance and superior in perfect straightness and roundness, by a method wherein the title manufacture is so constituted that synthetic resin is cast in the direction of a space for formation of a rotary shaft part and a cylindrical reinforcement material floats on a central shaft in the above-mentioned space. CONSTITUTION:A cylindrical reinforcement material 17 composed of a resin ring 18 by fitting over the material 17 is put within a cavity 10. In this instance, positioning is performed so that two pieces of rings 18 can be put into a space 16 for formation of a rotary shaft part in the cavity 10. Then ABS resin is cast into a nozzle touching part 11a by positioning an injection molding nozzle 11 under that state. The casting resin is entered strongly into the space 16 for formation of the rotary shaft part through pressure at the time of casting, in the cavity 10. In this instance, the casting resin arrives at the interior of the space 16 for formation of the rotary shaft while uniform pressure is being applied to the whole of the external circumferential surface of the ring 18 by passing through an air gap between the external circumference of the resin ring 18 fitted over the cylindrical reinforcement material 17 and a wall surface of the space 16. The cylindrical reinforcement material 17 floats to the center of the space 16 for formation of the rotary shaft part through the pressure and positioned coaxially.

Abstract: PURPOSE:To perform liquid feeding suitable for plural analysis methods only by the normal-reverse rotation of both cams by devising a means for setting the cam profile of a parallel-connected double plunger pump in such a way as to make the total feed liquid quantity of both plunger pumps constant at the normal rotation time of the cams. CONSTITUTION:When a parallel-connected double plunger pump 14 is driven after switching a change-over valve 19 onto the discharge drum 20 side, the moving phase sucked from a reservoir part 10 is delivered to a column 17 through a pressure sensor 15 and an injector 16. The respective components of a sample injected by the injector 16 are separated by the column 17 and detected by a detector 18. In the case of applying a single stage separation method, both cams of the pump 14 are rotated clockwise to hold total discharge quantity always constant and to perform precison liquid feeding. In the case of applying a recycle separation method, the change-over valve 19 is switched onto the recycle pipe 21 side to recycle the eluate having passed the detector 18, and simultaneously, both cams are rotated reversely to hold total suction quantity always constant.

Abstract: PURPOSE:To control arbitrarily the magnitude of an electromagnetic force acting on an energized coil, even in a uniform magnetic field, by making the opening and closing of a part of a magnetic shielding body possible, and by obtaining an electromagnetic propulsion force in the magnetic field. CONSTITUTION:The opening and closing of a part of a magnetic shielding body 4 are made possible, and by the extents of the opening and closing of the part of the magnetic shielding body 4, the intensity of a magnetic field 2 applied to a coil 1 is controlled, and as a result, the electromagnetic force (Lorentz's force) 3 acting on the coil 1 is made variable. For example, when the part of the magnetic shielding body 4 is closed, a propulsion force acts on the coil 1 in the right direction facing the figure. But, when the part of the magnetic shielding body 4 is opened, the electromagnetic propulsion forces (Lorentz's forces) 3 acting respectively in the right and left directions are balanced with each other, and as a result, the propulsion force scarcely acts on the coil 1. Thereby, even in a uniform magnetic field, the magnitude of the electromagnetic force 3 acting on the energized coil 1 is made controllable arbitrarily.
