Title: Production of electric welded steel pipe having excellent to electric welding corrosion and low-temperature toughness
Inventor: MURAYAMA HIROSHI
IPC: C21D9/50
Filed: 1984-03-26
Abstract: PURPOSE:To produce a high-strength electric welded oil-well steel pipe having excellent low-temp. toughness and resistance to electric welding corrosion in the electric weld zone by subjecting the electric weld zone of the electric welded steel pipe to a heat treatment including heating and cooling under specific conditions. CONSTITUTION:The electric weld zone of a steel pipe manufactured by electric welding is heated to 1,050-1,200 deg.C and is then quickly cooled at a high cooling rate of 30 deg.C/sec-150 deg.C/sec from a temp. range of 750-950 deg.C. The structure is finely grained and the low-temp. toughness is improved by such quick cooling treatment. Said weld zone is further heated within 1min at 400-700 deg.C so that the strain generated by the quick cooling is relieved by the stress relief treatment and the low-temp. toughness is additionally improved. The high-strength electric welded oil well steel pipe having the low-temp. toughness in the weld zone by electric welding approximately equal to the low temp. toughness of the base metal or higher than the same and having excellent resistance to electric welding corrosion is thus obtd.

Title: Print control system
Inventor: KONISHI MASAO
IPC: B41J2/435
Filed: 1978-05-16
Abstract: PURPOSE: To obtain a sufficient luminance even when characters different in size are printed by an electronic photo printer, by changing the period of raster scan for describing character images of a CRT display face according to the size of characters.  
     CONSTITUTION: When characters different considerably in size from normal characters are printed by an electronic photo printer by using character images of a CRT display face as a light source, the period of raster scan is changed according to the size of characters. For example, when large characters such as bar code are printed, the period is made longer (as shown in figure b) in comparison with the period (figure a) of raster scan for normal-size characters. Thus, luminance can be ensured similarly to the conventional system, so that detection of character images can be prevented from being impeded independently of a slight lowering of resolution.

Title: Copper covered steel wire
Inventor: TAKAYAMA TERUYUKI
IPC: H01B7/00
Filed: 1988-03-10
Abstract: PURPOSE:To enable obtaining a stranded wire superior in both flexing resistance and solderbility by covering the core of a steel wire having a specific carbon content with a copper layer. CONSTITUTION:The core of a steel wire containing 0.005 to 0.06 weight percentage of carbon is covered with a copper layer. When the carbon content exceeds 0.06 weight percentage, the degree of work hardening of the steel wire increases so much that the steel wire is liable to fracture when subjected to a bending and twisting processes. Also, when the carbon content drops below 0.005 weight percentage, the steel wire is frequently fractured due to an intervening material. Preferably. the coverage ratio of the copper is 20 to 60% by a volume ratio. According to the aforesaid construction, it is possible to obtain a wire for stranding superior in solderbility and platability on the surface and in strength against repeated and remarkable bending processes.
