Title: Building skeleton structure
Inventor: NAGAMI KAZUO
IPC: E04B2/84
Filed: 1994-09-22
Abstract: PURPOSE: To improve earthquake resisting performance by integrating sub-frames of approximately ladder shape formed of low yield material, into a main frame formed on columns and beams to construct the skeleton of a multistory building, and absorbing vibrational energy by the sub-frames. CONSTITUTION: Spandrel walls 6, 7 made of reinforced concrete (RC) and fitted to vertical beams 3 laid between columns 2a are integrally connected by sub- frames 5 formed of low yield strength material into approximately ladder shape, through steel plates 8 and stud bolts 9. When a skeleton is horizontally vibrated by an earthquake or the like, the vertical member 12 of the sub-frame 5 acts as a steel damper and yield-deformed earlier than the other members to absorb vibrational energy. In the case of buckling, only the sub-frame 5 is replaced and recovered in an early stage. The earthquake resistance of a building can thereby be improved.

Title: Method for setting welding torch
Inventor: ARAYA TAKESHI
IPC: B23K9/29
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To automatically set a torch position in a groove in a preparatory work for welding. SOLUTION: With an inclined electrode 4 oscillated in an upper part in a groove, it comes into contact with one side but not with the opposite side. Then, the Y-axis is slightly moved to F side by a slide motor MY. These oscillating motions are repeated until the tip end of the electrode comes into contact with both walls of the groove. With both walls of the groove detected, the electrode 3 is found nearly in the center of the groove; therefore, the oscillating motion is stopped with the inclined electrode 4 facing the center of the groove. Then, the inclined electrode 4 is moved to the groove bottom (root part) by means of a Z-axis slide mechanism. With contact detected between the inclined electrode 4 and a base material 2 by a contact detector, the inclined electrode 4 is subsequently pulled up for a proper distance to complete a torch setting.
