Title: Dc welding on inner surface of pipe
Inventor: ISHIKAWA YASUSHI
IPC: B23K9/025
Filed: 1980-02-14
Abstract: PURPOSE: To prevent magnetization of a pipe body and to stabilize the arc, by applying an arc current in the reverse direction to the welding current, by fitting an earthing cable to the end of the pipe reverse to the progross of welding diection.  
     CONSTITUTION: The welding current is passed from welding DC power source 6 to power cable 3 of welding torch 2 extended in the opposite direction of welding progress direction 10, and welding on beveling 7 which has not been welded of pipe body 1, is performed with the arc from welding torch 2. When pipe body 1 is welded with DC, the magnetic field generated at the nonwelded beveling section near the arc will be magnetic field HW generated by the welding curreng flowing through the parallel section of pipe body of power cable 3 and magnetic field HA generated by the welding current flowing through the vertical section of pipe body and the current of arc pillar. When the pipe diameter is larger, magnetic field HA is larger than magnetic field HW, and the welding is interrupted. To prevent such interruption, therefore, earthing cable 5a is fitted to the end of pipe and magnetic field HE is formed in the same direction with magnetic field HW by passing the arc current through the inside of pipe body 1 in the opposite direction of welding current. By this, magnetic field HA is negated and magnetization of pipe body 1 is prevented.

Filed: 1993-02-03
Abstract: PURPOSE:To shield insolation efficiently while minimally limiting the hindrance of a view by installing auxiliary slats on the top faces of each slat and automatically rotating solar cells as power supply sources. CONSTITUTION:When solar rays directly strike against solar cells 6... on auxiliary slats 4, 4, electricity is generated and electromagnets 7... are supplied with power, and the indoor sides of the electromagnets 7 are rotated upward while using pins 5 as axes by the repulsive power of the electromagnets 7 and permanent magnets. Accordingly, the auxiliary slats 4 are erected obliquely in the slat 1, and insolation into an indoor section is shielded. Since the auxiliary slats 4, which do not receive solar rays directly, are not erected, on the other hand, a window is not closed more than required, and the obstruction of a view is limited in the irreducible minimum of a demand.
