摘要： A fuel vapor processor has a fuel tank, a canister, a vapor pipe, a recovery pipe, an air pipe, a suction device, a vapor pipe valve, an air pipe valve, and a pressure regulator. The vapor pipe leads fuel vapor generated in the fuel tank to the canister for trapping the fuel vapor in the canister. The recovery pipe recoveries the fuel vapor desorbed from the canister into the fuel tank. The air pipe communicates the canister with the atmosphere. The suction device is disposed on the recovery pipe for desorbing the fuel vapor trapped in the canister. The pressure regulator is communicated with the air pipe between the air pipe valve and the canister in order to allow gas flow from the atmosphere toward the canister. During desorption of the fuel vapor due to the suction device, the vapor pipe valve and the air pipe valve are closed, and negative pressure is kept in the canister such that the fuel vapor is desorbed from the canister and fresh air is led into the canister via the pressure regulator.

This resistance welding method comprises a calculating step of calculating resistance ratio X of a second electric resistance value R2 of workpieces to be joined in residual heat after Joule heating stops to a first electric resistance value R1 of the workpieces immediately before the Joule heating stops or vice versa (R2/R1 or R1/R2); a determining step of determining whether the resistance ratio X is equal to or greater than a threshold value Xn, and a reheating step of carrying out the Joule heating again when the resistance ratio X is smaller than the threshold value Xn. Thereby at least part of a welding portion is melted and solidified to reliably form a nugget, and a stably resistance-welded member can be provided.

摘要： In a resistance welding method, by controlling the power amount from a melting start time onward, the weld quality may be stabilized efficiently, even when a disturbance is present, because of the correlation between the amount of power input from the melting start start time and a resulting nugget. The resistance welding method includes: pressing an electrode against a workpiece; inputting power to the workpiece through the electrode to subject the workpiece to Joule heating; detecting the melting start time, which is the time at which at least a portion of the faying portion of a workpiece starts to melt when subjected to Joule heating; calculating a first power amount input into the workpiece from the melting start time; and determining whether the first power amount has reached a first set value; and continuing the Joule heating until the first power amount reaches the first set value.

摘要： A fuel injection controller for an internal combustion engine. The engine includes a fuel vapor treatment device having a collector for collecting fuel vapor generating in a fuel tank; a purge line that introduces purge gas into an intake passage of the engine, the purge gas being a mixture of fuel vapor released from the collector and air; and a purge valve provided in the purge line to adjust flow rate of the purge gas. The fuel injection controller corrects an amount of fuel injected from an fuel injection valve based on an amount of fuel vapor contained in the purge gas flowing into a combustion chamber of the engine. The fuel injection controller comprises an estimation section for estimating the inflow amount of the purge gas flowing into the combustion chamber based on a passed amount of purge gas that has passed through the purge valve and a compensation value for compensating transportation delay. The compensation value is set based on internal pressure of the intake passage and velocity of intake air that flows into the combustion chamber.
