Title: Method for forming through hole having taper shape in object to be machined with press and hole machining tool therefor
Inventor: TAKEUCHI HIROTATSU
IPC: B21D28/34
Filed: 1995-08-03
Abstract: PURPOSE: To provide a forming method which is able to form a through hole having a taper shape by one time pressing at once. CONSTITUTION: With a drilling punch 1 attached on a press, an object to be machined is drilled by using a punch part 1a with a small diameter formed on a tip of the punch 1. A hole 11 drilled at this time is formed to a broken face that the lower end part of the hole is opened in pressing, but a taper face is formed on the internal face of hole 11 with the deformation processing with a taper forming part 1b having a little larger diameter than the diameter of the hole and a taper face T making this hole 11 as the guide. 'Burr 3a' is formed on the external circumference of the hole 11 following to the deformation processing, but this 'burr 3a' is prevented from generating with a pressing part 1c formed on the drilling punch 1. By executing the above processings by one time pressing, the through hole having the plural number of taper shapes can be formed simply.

Title: Sideways welding method
Inventor: TANAKA KISABUROU
IPC: B23K9/08
Filed: 1981-12-11
Abstract: PURPOSE:To prevent drip of a weld bead in sideways consumable electrode type gas shielded DC are welding, by letting flow arc current that flows in the welded material in the direction opposite to the direction of welding, and at the same time, allowing magnetic line of force to act on the surface of the molten pool. CONSTITUTION:An electromagnet 11 is inserted into the groove of a welded material 1 and a magnetic field 8 that crosses the molten metal formed by the welding arc is generated. Electromagnetic force 10 that moves the molten metal upward is formed by the magnetic field 8 and Fleming's left-hand rule caused by mutual action of current 9 that flows in the molten metal 5 in the direction of earth. By the action of this electromagnetic force 10, the molten bead is dripped by gravity, and undercut U is generated in the upper side and overlap O is generated in the lower side. Thus, occurrence of poor penetration of the bead of next layer can be prevented.

Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent foreign matters in lubricating oil from adhering to a collar by fixing fluorine resin on the surface of the collar slidingly touching a thrust bearing. SOLUTION: A collar 4 is constructed of a base material 20 and fluorine resin 21 arranged on the surface of the base material 20. As a loading side thrust bearing 6 is arranged one side while an unloading side thrust bearing 15 is arranged on the other side, the fluororesin 21 is arranged on both faces of the collar 4. Between the collar 4 and a lubricating oil, a fluid charging phenomenon is generated macroly, and as a result, foreign matter particles in the oil tends to adhere to the collar 4 by an electrostatic action. However, the fluororesin 21 is provided with small adhesion with the foreign matters, so that adhesion and accumulation of the foreign matters on the collar 4 is prevented.  Therefore, adhesion of the foreign matters in the oil onto the collar 4 can be prevented when the fluororesin 21 is fixed on the collar 4 surface which is brought into slide contact with the land part of the thrust bearing.
