Inventor: SOFUE SUNAO
IPC: B23K11/34
Filed: 1986-11-07
Abstract: PURPOSE:To improve the corrosion resistance and welding efficiency of steel sheet by sprinkling and spreading or sticking the increasing agent of electric resistance between steel sheets on the joint of the steel sheets in advance and then, performing the electric resistance welding. CONSTITUTION:The resistance increasing agent 4 made of alumina powder, etc., is interposed between the two steel sheets 7 to which galvanized layers 2 are formed on both surfaces of base metals 3 to form a gap 5 on the mating face of the steel sheets 7. When electrodes 1 are pressed against the steel sheets 7 to perform the electric welding, the electric resistance is high on the mating face, so the temp. of the part become higher preferentially than other parts. At this time, the galvanized layers 2 are first molten and then, the base metals 3 are molten thinly to form a nugget. Since the welding is finished with little current or in a short period of time, the welding efficiency is improved by this method. Further, since the dissipating quantity of zinc of the galvanized layers 2 is reduced, the corrosion resistance of the steel sheets of a welded zone is improved.

Title: Fuel injection valve
Inventor: IKEGAMI MAKOTO
IPC: F02M55/02
Filed: 1989-10-12
Abstract: PURPOSE:To raise the flow speed and pressure of a fuel fluid flowing through a pipe and increase the fluid pressure at the outlet from the pipe by reducing the pipeline section area from inlet of pipe, which is fixed to the discharge port of a fuel injection pump, toward the outlet. CONSTITUTION:A plunger 2 is moved right in the condition that an injection device is filled with fuel liquid, and when a run-off hole 3 is blocked by the plunger 2, compression of the fuel liquid is begun. Now the compression wave propagates from the left end of pipeline 4 to the right at the sonic speed, and the pipeline section area decreases with distance in the compression wave propagating direction, so that the peak pressure of the compression wave increases with propagation of the compression wave. If there is a decrease in the pipeline section area anywhere on the pipeline 4a and if compression wave, i.e., discontinuous surface of flow speed and pressure, is going to pass this place, a leftwise reflex wave to decrease the flow speed according to the degree of section area change and to raise the pressure is, as shown by Y, produced after the passage compared with the condition before passage as shown by X. As for discontinuous surface of the compression wave propagating rightwise, the flow speed and pressure are increased because the liquid is further compressed due to the inertia of the liquid.
