Title: Wire dot printing head
Inventor: SUZUKI HIROYA
IPC: H01F7/14
Filed: 1982-08-04
Abstract: PURPOSE:To enable to enhance printing speed and to reduce a rise in head temperature, by a method wherein a powder molded magnetic material having a high resistivity is used as a material for a magnetic circuit member constituting a dot printing head. CONSTITUTION:When an electric current is passed through a coil 4 by a printing signal and a core 1 is thereby excited, an armature 3 is attractedly moved downward, and a dot is printed by the tip of a pin 5. When a material high in resistivity but low in permeability, such as an Mn-Zn base soft magnetic material, is used as a material for the core 1, both a coil current and an armature flux rise up quickly, so that the operating speed of the head is enhanced. In addition, since the material has the high resistivity, the conductance for an eddy current can be reduced. Accordingly, the printing speed can be enhanced, and the rise in the head temperature can be reduced.

Abstract: PURPOSE:To prevent lowering of toughness of welded metal due to absorption of oxygen in gas shielded arc welding by adopting double gas shielded welding, and using a filler wire blended with a deoxidizer, and at the same time, magnetically agitaing molten metal. CONSTITUTION:Steel for low temperature such as 3.5% Ni steel, 9% Ni steel etc. for which low temperature toughness is required is welded by gas shielded a arc welding such as TIG welding and MIG welding. In the case of TIG welding, a filler wire 7a blended with Al, Ti, Si, Mn etc. as deoxidizer is used. Further, secondary shielding gas 10 composed of reducing H2 gas is supplied to outside of primary shielding gas 6 of Ar etc. as shielding gas.
