Title: Laser beam welding method for metallic thin sheet
Inventor: ARAI SHINICHI
IPC: B23K26/21
Filed: 1985-11-06
Abstract: PURPOSE:To reduce the generation of welding defects by making a laser beam incident at the specified inclined angle on the vertical line at the welding butt part of a metallic thin sheet. CONSTITUTION:The laser beam welding is performed by abutting the metallic thin sheet 1, 1 to be butt-welded by a straight line IJ. In this case, the incident route of the laser beam is regulated in the range which is demarcated by the conical face having 40 deg. half apex angle which makes a welding point P as the apex and the plane having + or -15 inclination theta2 to the plane including the vertical line at the straight line IJ and welding point P. The incomplete deposition based on the excess irradiation energy in welding and the reduction in the laser output can be prevented by performing the incidence of the laser beam in this regulated range. Consequently, the burn through in welding at high speed is prevented and the generation of welding defects can be reduced.

Title: Thick-film resistive paste and thick film resistor
Inventor: ONOE KAZUAKI
IPC: H01C17/06
Filed: 1991-09-04
Abstract: PURPOSE:To realize a stable high resistive region in glass containing 15wt.% or more conductive powder, by adding 0.5 to 5wt.% tin oxide and/or titanium oxide to the glass. CONSTITUTION:The main elements of glass with their contents are 45 to 75wt.% lead oxide, 25 to 50wt.% silicon oxide, and 0.5 to 5wt.% boron oxide. In addition to these ingredients, the glass contains 0.5 to 5wt.% tin oxide and/or titanium oxide. When the content of tin oxide and/or titanium oxide is less than these percentages, the effect is reduced. When the content percentage is too large, a resistive film obtained through baking has a larger coefficient of thermal expansion, which makes the adhesion strength inadequately small. Consequently, the content percentage of the tin oxide and/or titanium oxide needs 0.5 to 5wt.%, and thereby a high resistive region of 5MOMEGA or above per square can be made stable in glass containing 15wt.% or more conductive powder.
