Title: Method for joining hot rolled sheets
Inventor: IIFUSHI JUNICHI
IPC: B21B1/22
Filed: 1986-11-14
Abstract: PURPOSE:To facilitate centering and to shorten the time for welding in a continuous hot rolling method for joining and rolling metallic sheets by forming the ends of the two sheet materials to a trapezoidal shape, welding only the central parallel parts and coating a flux to the other joint parts. CONSTITUTION:The front and rear ends of the sheets are cut by a drum shear, etc., to the trapezoidal shape which has the parallel part C near the transverse center of the sheets and is tapered in the rest. Such sheets A, B are butted and only the parallel parts C are welded. The flux Fc is coated on the other tapered parts and the oxidized scale of the joint surface is removed to activate the surfaces so that the surfaces are in the easily press-weldable state. Self- centering is possible even with the sheet materials having different widths and the generation of a trouble such as crooked rolling is obviated if the sheet ends to be butted are formed to the trapezoidal shape in the above-mentioned manner. The sheets A, B joined in said manner are hot rolled and the joint part is thereby completely press-welded.

Title: Welded structure and its welding method
Inventor: NISHITANI SHOICHIRO
IPC: B23K9/23
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To improve the strength of a weld zone by flitting end faces of a pair of cylindrical members to each other, and forming a second weld zone extending to an outer circumferential surface of the cylindrical members across a fully fillet welded part between the outer circumferential surfaces. SOLUTION: A pair of cylindrical members 10, 11 are press flitted to each other with a margin at an end part, and the MAG welding is achieved so that the whole circumference between an end face of the cylindrical member 10 and an outer circumferential surface of the cylindrical member 11 is deposited by a fillet welded zone 12, and a second welded zone 13 is extended between the outer circumferential surfaces of the cylindrical members 10, 11 across the fillet welded zone 12. Because the second welded zone 13 is contracted and deformed, and the diameter of a fitted part of the cylindrical member 10 is reduced, the fitted part of the cylindrical member 11 is tightened, generation of the bending moment produced between the flitted parts due to the internal pressure is suppressed, and the strength is improved.  The second welded zone 13 is arranged on the symmetrical position on the circumference. The strength of the welded zone is thus improved.

Title: Push-pull output integrated circuit
Inventor: YOSHIDA HIROSHI
IPC: H03F3/30
Filed: 1984-12-24
Abstract: PURPOSE:To avoid consumption of useless electric power by setting a flowing current at a level equal to the charging/discharging current obtained when the voltage of a capacitor is changed by a level between logical valves '1' and '0'. CONSTITUTION:When a rectangular signal supplied to an input terminal 1 changes to '0' from '1', a signal Vc differentiated by a capacitor C is obtained and impressed to the base of a pnp transistor TRT4. As the coincidence is obtained between Vdd and GND for the voltage direction of the signal Vc, the voltage is impressed to the base of the TRT4 so that a deep vias is applied to said base from an OFF state. Thus the TRT4 is turned on to charge the gate capacity of a TRT3. When the input signal is changed to '1' from '0', a TRT2 is turned on and the gate capacity of the TRT3 is drawn out in the form oaf a drain current. Then the TRT3 is turned off. In other words, both TRT3 and T2 are turned on and off according to the change of the input signal.
