Title: Spot welding method for high tension steel sheet
Inventor: SOFUE SUNAO
IPC: B23K11/10
Filed: 1988-05-14
Abstract: PURPOSE:To enable a welding operation at low current in short time by welding by interposing the granular body group of a difficult to conduct in the zone corresponding to the nugget shape of a joint joining face by the welding joint consisting of a high tension steel sheet at its one part at least. CONSTITUTION:The granular body 12 interposed in the joining boundary of the mating face of the joint 10 whose one part at least is composed of a high tension steel sheet is uniformly mixed in a consistence body B in its necessary amt. and the specified gap functioning for the increase in resistance is secured only by dropping to the joint joining face of one part its optimum amt. When the joint 10 is welded by pressurizing by an electrode 18, a partial contact is caused on the mutual joints by the biting and deflection of the granular body 12 to the joint and a current is passed. An abrupt heating is induced by being interrupted by the granular body 12 and the electric resistance of the joining zone becomes high enough. At the nugget forming part of the mating face becoming in the highest temp. the consistence body layer is discharged to the external part with its expansion by vaporizing, the joint 10 is melted and a thin nugget is formed. The welding work is performed in a short time with less power consumption and the good welding of an optimum nugget is enabled.

Title: Ignition time control device of engine
Inventor: OKA KENJI
IPC: F02P5/15
Filed: 1993-04-20
Abstract: PURPOSE:To prevent the torque fluctuation caused by sudden changes in ignition timing by controlling ignition timing based on an actual charge efficiency in a lean burn running area and based on the throttle opening of high resolution in shifting from this running area to a high charge efficiency rate area. CONSTITUTION:A theoretical air-fuel ratio controlling means P1 controls an air-fuel ratio so as to make it become a theoretical air-fuel ratio according to the running state of an engine P2, and a first ignition timing controlling device P3 controls ignition timing so that the air-fuel ratio becomes a lean air-fuel ratio from a low charge efficiency area to a specified charge efficiency area. However, when a shift judging mean P4 judges that an actual charge efficiency shifted to a high charge efficiency area from a specified charge efficiency area, a second ignition timing controlling means P5 gradually makes the air-fuel ratio equal to the theoretical air-fuel ratio and also control ignition timing according to high resolution throttle opening. As a result, the torque fluctuation caused by sudden changes in ignition timing can surely be prevented.
